- * @brief CMSIS Cortex-M0+ Device Peripheral Access Layer Header File.
- * This file contains all the peripheral register's definitions, bits
- * definitions and memory mapping for STM32L0xx devices.
- *
- * The file is the unique include file that the application programmer
- * is using in the C source code, usually in main.c. This file contains:
- * - Configuration section that allows to select:
- * - The device used in the target application
- * - To use or not the peripheralâs drivers in application code(i.e.
- * code will be based on direct access to peripheralâs registers
- * rather than drivers API), this option is controlled by
- * "#define USE_HAL_DRIVER"

- ##### Initialization and de-initialization functions #####
- ===============================================================================
- [..] This section provides functions allowing to:
- (+) Initializes the Flash interface, the NVIC allocation and initial clock
- configuration. It initializes the source of time base also when timeout
- is needed and the backup domain when enabled.
- (+) de-Initializes common part of the HAL.
- (+) Configure The time base source to have 1ms time base with a dedicated
- Tick interrupt priority.
- (++) Systick timer is used by default as source of time base, but user
- can eventually implement his proper time base source (a general purpose
- timer for example or other time source), keeping in mind that Time base
- duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and
- handled in milliseconds basis.
- (++) Time base configuration function (HAL_InitTick ()) is called automatically
- at the beginning of the program after reset by HAL_Init() or at any time
- when clock is configured, by HAL_RCC_ClockConfig().
- (++) Source of time base is configured to generate interrupts at regular
- time intervals. Care must be taken if HAL_Delay() is called from a
- peripheral ISR process, the Tick interrupt line must have higher priority
- (numerically lower) than the peripheral interrupt. Otherwise the caller
- ISR process will be blocked.
- (++) functions affecting time base configurations are declared as __Weak
- to make override possible in case of other implementations in user file.

- * peripheral:
- * + Initialization and de-initialization functions
- * ++ Initialization and Configuration of ADC
- * + Operation functions

- @verbatim
- ==============================================================================
- ##### ADC specific features #####
- ==============================================================================
- [..]
- (#) 12-bit, 10-bit, 8-bit or 6-bit configurable resolution.
-
- (#) A built-in hardware oversampler allows to improve analog performances
- while off-loading the related computational burden from the CPU.
-
- (#) Interrupt generation at the end of conversion and in case of analog
- watchdog or overrun events.
-
- (#) Single and continuous conversion modes.
-
- (#) Scan or discontinuous mode conversion of channel 0 to channel 18.
-
- (#) Configurable scan direction (Upward from channel 0 to 18 or Backward from
- channel 18 to channel 0)
-
- (#) Data alignment with in-built data coherency.
-
- (#) Channel-wise programmable sampling time.
-
- (#) External trigger option with configurable polarity.
-
- (#) DMA request generation during regular channel conversion.
-
- (#) ADC supply requirements: 2.4 V to 3.6 V at full speed and down to 1.8 V at
- slower speed.
-
- (#) ADC input range: VREF- =VIN =VREF+.
-
- (#) ADC self-calibration.
-
- (#) ADC is automatically powered off (AutoOff mode) except during the active
- conversion phase. This dramatically reduces the power consumption of the
- ADC.
-
- (#) Wait mode to prevent ADC overrun in applications with low frequency.
-
-
- ##### How to use this driver #####
- ==============================================================================
- [..]
-
- (#) Enable the ADC interface
- As prerequisite, into HAL_ADC_MspInit(), ADC clock must be configured
- at RCC top level.
-
- Depending on both possible clock sources: PCLK clock or ADC asynchronous
- clock.
- __ADC1_CLK_ENABLE();
-
-
- (#) ADC pins configuration
- (++) Enable the clock for the ADC GPIOs using the following function:
- __GPIOx_CLK_ENABLE();
- (++) Configure these ADC pins in analog mode using HAL_GPIO_Init();
-
- (#) Configure the ADC parameters (conversion resolution, oversampler,
- data alignment, continuous mode,...) using the HAL_ADC_Init() function.
-
- (#) Activate the ADC peripheral using one of the start functions:
- HAL_ADC_Start(), HAL_ADC_Start_IT() or HAL_ADC_Start_DMA()
-
- *** Channels configuration ***
- ===============================
- [..]
- (+) To configure the ADC channels group, use HAL_ADC_ConfigChannel() function.
- (+) To read the ADC converted values, use the HAL_ADC_GetValue() function.
-
- *** DMA feature configuration ***
- =================================
- [..]
- (+) To enable the DMA mode, use the HAL_ADC_Start_DMA() function.
- (+) To enable the generation of DMA requests continuously at the end of
- the last DMA transfer, set .Init.DMAContinuousRequests to ENABLE and
- call HAL_ADC_Init() function.

-================================================================================
- ##### COMP Peripheral features #####
-================================================================================
-
- [..]
- The STM32L0xx device family integrates 2 analog comparators COMP1 and COMP2:
- (#) The non inverting input and inverting input can be set to GPIO pins
- as shown in table1. COMP Inputs below.
-
- (#) The COMP output is available using HAL_COMP_GetOutputLevel()
- and can be set on GPIO pins. Refer to table 2. COMP Outputs below.
-
- (#) The COMP output can be redirected to embedded timers (TIM2, TIM21, TIM22...) and LPTIM
- Refer to TIM and LPTIM drivers.
-
- (#) The comparators COMP1 and COMP2 can be combined in window mode and only COMP2 non inverting input can be used as non-inverting input.
-
- (#) The 2 comparators have interrupt capability with wake-up
- from Sleep and Stop modes (through the EXTI controller):
- (++) COMP1 is internally connected to EXTI Line 21
- (++) COMP2 is internally connected to EXTI Line 22
-
- From the corresponding IRQ handler, the right interrupt source can be retrieved with the
- macro __HAL_COMP_EXTI_GET_FLAG(). Possible values are:
- (++) COMP_EXTI_LINE_COMP1_EVENT
- (++) COMP_EXTI_LINE_COMP2_EVENT
-
-

-
- ##### How to use this driver #####
-================================================================================
- [..]
- This driver provides functions to configure and program the Comparators of all STM32L0xx devices.
-
- To use the comparator, perform the following steps:
-
- (#) Initialize the COMP low level resources by implementing the HAL_COMP_MspInit().
- (++) Configure the comparator input in analog mode using HAL_GPIO_Init().
- (++) Configure the comparator output in alternate function mode using HAL_GPIO_Init() to map the comparator
- output to the GPIO pin.
- (++) If required enable the VREFINT reference using HAL_VREFINT_Cmd() and HAL_COMP_EnableBuffer_Cmd().
- (++) If required enable the COMP interrupt by configuring and enabling EXTI line in Interrupt mode and
- selecting the desired sensitivity level using HAL_GPIO_Init() function. After that enable the comparator
- interrupt vector using HAL_NVIC_EnableIRQ() function.
-
- (#) Configure the comparator using HAL_COMP_Init() function:
- (++) Select the inverting input
- (++) Select the non-inverting input
- (++) Select the output polarity
- (++) Select the power mode
- (++) Select the window mode
-
- (#) Enable the comparator using HAL_COMP_Start() function

- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
-
- [..]
- *** How to configure Interrupts using CORTEX HAL driver ***
- ===========================================================
- [..]
- This section provide functions allowing to configure the NVIC interrupts (IRQ).
- The Cortex-M0+ exceptions are managed by CMSIS functions.
- (#) Enable and Configure the priority of the selected IRQ Channels.
- The priority can be 0..3.
-
- -@- Lower priority values gives higher priority.
- -@- Priority Order:
- (#@) Lowest priority.
- (#@) Lowest hardware priority (IRQn position).
-
- (#) Configure the priority of the selected IRQ Channels using HAL_NVIC_SetPriority()
-
- (#) Enable the selected IRQ Channels using HAL_NVIC_EnableIRQ()
-
- [..]
- *** How to configure Systick using CORTEX HAL driver ***
- ========================================================
- [..]
- Setup SysTick Timer for time base
-
- (+) The HAL_SYSTICK_Config()function calls the SysTick_Config() function which
- is a CMSIS function that:
- (++) Configures the SysTick Reload register with value passed as function parameter.
- (++) Configures the SysTick IRQ priority to the lowest value (0x03).
- (++) Resets the SysTick Counter register.
- (++) Configures the SysTick Counter clock source to be Core Clock Source (HCLK).
- (++) Enables the SysTick Interrupt.
- (++) Starts the SysTick Counter.
-
- (+) You can change the SysTick Clock source to be HCLK_Div8 by calling the macro
- __HAL_CORTEX_SYSTICKCLK_CONFIG(SYSTICK_CLKSOURCE_HCLK_DIV8) just after the
- HAL_SYSTICK_Config() function call. The __HAL_CORTEX_SYSTICKCLK_CONFIG() macro is defined
- inside the stm32l0xx_hal_cortex.h file.
-
- (+) You can change the SysTick IRQ priority by calling the
- HAL_NVIC_SetPriority(SysTick_IRQn,...) function just after the HAL_SYSTICK_Config() function
- call. The HAL_NVIC_SetPriority() call the NVIC_SetPriority() function which is a CMSIS function.
-
- (+) To adjust the SysTick time base, use the following formula:
-
- Reload Value = SysTick Counter Clock (Hz) x Desired Time base (s)
- (++) Reload Value is the parameter to be passed for HAL_SYSTICK_Config() function
- (++) Reload Value should not exceed 0xFFFFFF

- *
- * This file provides firmware functions to manage the following

- *
- @verbatim
- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..]
- The CRYP HAL driver can be used as follows:
-
- (#)Initialize the CRYP low level resources by implementing the HAL_CRYP_MspInit():
- (##) Enable the CRYP interface clock using __CRYP_CLK_ENABLE()
- (##) In case of using interrupts (e.g. HAL_AES_ECB_Encrypt_IT())
- (+) Configure the CRYP interrupt priority using HAL_NVIC_SetPriority()
- (+) Enable the CRYP IRQ handler using HAL_NVIC_EnableIRQ()
- (+) In CRYP IRQ handler, call HAL_CRYP_IRQHandler()
- (##) In case of using DMA to control data transfer (e.g. HAL_AES_ECB_Encrypt_DMA())
- (+) Enable the DMA1 interface clock using
- (++) __DMA1_CLK_ENABLE()
- (+) Configure and enable two DMA Channels one for managing data transfer from
- memory to peripheral (input channel) and another channel for managing data
- transfer from peripheral to memory (output channel)
- (+) Associate the initilalized DMA handle to the CRYP DMA handle
- using __HAL_LINKDMA()
- (+) Configure the priority and enable the NVIC for the transfer complete
- interrupt on the two DMA Streams. The output stream should have higher
- priority than the input stream.
- (++) HAL_NVIC_SetPriority()
- (++) HAL_NVIC_EnableIRQ()
-
- (#)Initialize the CRYP HAL using HAL_CRYP_Init(). This function configures mainly:
- (##) The data type: 1-bit, 8-bit, 16-bit and 32-bit
- (##) The encryption/decryption key.
- (##) The initialization vector (counter). It is not used ECB mode.
-
- (#)Three processing (encryption/decryption) functions are available:
- (##) Polling mode: encryption and decryption APIs are blocking functions
- i.e. they process the data and wait till the processing is finished
- e.g. HAL_CRYP_AESCBC_Encrypt()
- (##) Interrupt mode: encryption and decryption APIs are not blocking functions
- i.e. they process the data under interrupt
- e.g. HAL_CRYP_AESCBC_Encrypt_IT()
- (##) DMA mode: encryption and decryption APIs are not blocking functions
- i.e. the data transfer is ensured by DMA
- e.g. HAL_CRYP_AESCBC_Encrypt_DMA()
-
- (#)When the processing function is called at first time after HAL_CRYP_Init()
- the CRYP peripheral is initialized and processes the buffer in input.
- At second call, the processing function performs an append of the already
- processed buffer.
- When a new data block is to be processed, call HAL_CRYP_Init() then the
- processing function.
-
- (#)Call HAL_CRYP_DeInit() to deinitialize the CRYP peripheral.

- *

- * + Computation completed callback.
- *
- @verbatim
- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..]
- The CRYP HAL driver can be used as follows:
-
- (#)Initialize the CRYP low level resources by implementing the HAL_CRYP_MspInit():
- (##) Enable the CRYP interface clock using __CRYP_CLK_ENABLE()
- (##) In case of using interrupts (e.g. HAL_AES_ECB_Encrypt_IT())
- (+) Configure the CRYP interrupt priority using HAL_NVIC_SetPriority()
- (+) Enable the CRYP IRQ handler using HAL_NVIC_EnableIRQ()
- (+) In CRYP IRQ handler, call HAL_CRYP_IRQHandler()
- (##) In case of using DMA to control data transfer (e.g. HAL_AES_ECB_Encrypt_DMA())
- (+) Enable the DMA1 interface clock using
- (++) __DMA1_CLK_ENABLE()
- (+) Configure and enable two DMA Channels one for managing data transfer from
- memory to peripheral (input channel) and another channel for managing data
- transfer from peripheral to memory (output channel)
- (+) Associate the initilalized DMA handle to the CRYP DMA handle
- using __HAL_LINKDMA()
- (+) Configure the priority and enable the NVIC for the transfer complete
- interrupt on the two DMA Streams. The output stream should have higher
- priority than the input stream.
- (++) HAL_NVIC_SetPriority()
- (++) HAL_NVIC_EnableIRQ()
-
- (#)Initialize the CRYP HAL using HAL_CRYP_Init(). This function configures mainly:
- (##) The data type: 1-bit, 8-bit, 16-bit and 32-bit
- (##) The encryption/decryption key.
- (##) The initialization vector (counter). It is not used ECB mode.
-
- (#)Three processing (encryption/decryption) functions are available:
- (##) Polling mode: encryption and decryption APIs are blocking functions
- i.e. they process the data and wait till the processing is finished
- e.g. HAL_CRYP_AESCBC_Encrypt()
- (##) Interrupt mode: encryption and decryption APIs are not blocking functions
- i.e. they process the data under interrupt
- e.g. HAL_CRYP_AESCBC_Encrypt_IT()
- (##) DMA mode: encryption and decryption APIs are not blocking functions
- i.e. the data transfer is ensured by DMA
- e.g. HAL_CRYP_AESCBC_Encrypt_DMA()
-
- (#)When the processing function is called at first time after HAL_CRYP_Init()
- the CRYP peripheral is initialized and processes the buffer in input.
- At second call, the processing function performs an append of the already
- processed buffer.
- When a new data block is to be processed, call HAL_CRYP_Init() then the
- processing function.
-
- (#)Call HAL_CRYP_DeInit() to deinitialize the CRYP peripheral.

- * + DMA management
- *

- @verbatim
- ==============================================================================
- ##### DAC Peripheral features #####
- ==============================================================================
- [..]
- *** DAC Channels ***
- ====================
- [..]
- The device integrates 1 12-bit Digital Analog Converters:
- (#) DAC channel1 with DAC_OUT1 (PA4) as output
-
- *** DAC Triggers ***
- ====================
- [..]
- Digital to Analog conversion can be non-triggered using DAC_Trigger_None
- and DAC_OUT1/DAC_OUT2 is available once writing to DHRx register.
- [..]
- Digital to Analog conversion can be triggered by:
- (#) External event: EXTI Line 9 (any GPIOx_Pin9) using DAC_Trigger_Ext_IT9.
- The used pin (GPIOx_Pin9) must be configured in input mode.
-
- (#) Timers TRGO: TIM2, TIM6 and TIM21
- (DAC_Trigger_T2_TRGO, DAC_Trigger_T6_TRGO...)
-
- (#) Software using DAC_Trigger_Software
-
- *** DAC Buffer mode feature ***
- ===============================
- [..]
- Each DAC channel integrates an output buffer that can be used to
- reduce the output impedance, and to drive external loads directly
- without having to add an external operational amplifier.
- To enable, the output buffer use
- sConfig.DAC_OutputBuffer = DAC_OutputBuffer_Enable;
- [..]
- (@) Refer to the device datasheet for more details about output
- impedance value with and without output buffer.
-
- *** DAC wave generation feature ***
- ===================================
- [..]
- Both DAC channels can be used to generate
- (#) Noise wave using HAL_DAC_NoiseWaveGenerate()
- (#) Triangle wave using HAL_DAC_TriangleWaveGenerate()
-
- *** DAC data format ***
- =======================
- [..]
- The DAC data format can be:
- (#) 8-bit right alignment using DAC_ALIGN_8B_R
- (#) 12-bit left alignment using DAC_ALIGN_12B_L
- (#) 12-bit right alignment using DAC_ALIGN_12B_R
-
- *** DAC data value to voltage correspondence ***
- ================================================
- [..]
- The analog output voltage on each DAC channel pin is determined
- by the following equation:
- DAC_OUTx = VREF+ * DOR / 4095
- with DOR is the Data Output Register
- VEF+ is the input voltage reference (refer to the device datasheet)
- e.g. To set DAC_OUT1 to 0.7V, use
- Assuming that VREF+ = 3.3V, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V
-
- *** DMA requests ***
- =====================
- [..]
- A DMA1 request can be generated when an external trigger (but not
- a software trigger) occurs if DMA1 requests are enabled using
- HAL_DAC_Start_DMA()
- [..]
- DMA1 requests are mapped as following:
- (#) DAC channel1 : mapped on DMA1 Request9 channel2 which must be
- already configured
-
-
- ##### How to use this driver #####
- ==============================================================================
- [..]
- (+) DAC APB clock must be enabled to get write access to DAC
- registers using HAL_DAC_Init()
- (+) Configure DAC_OUTx (DAC_OUT1: PA4) in analog mode.
- (+) Configure the DAC channel using HAL_DAC_ConfigChannel() function.
- (+) Enable the DAC channel using HAL_DAC_Start() or HAL_DAC_Start_DMA functions

- * @author MCD Application Team
- * @version V1.1.0
- * @date 18-June-2014
- * @brief DMA HAL module driver.
- *
- * This file provides firmware functions to manage the following
- * functionalities of the Direct Memory Access (DMA) peripheral:
- * + Initialization/de-initialization functions
- * + I/O operation functions
- * + Peripheral State functions
- *
- *
- @verbatim
- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..]
- (#) Enable and configure the peripheral to be connected to the DMA Channel
- (except for internal SRAM / FLASH memories: no initialization is
- necessary).
-
- (#) For a given Channel, program the required configuration through the following parameters:
- Channel request, Transfer Direction, Source and Destination data formats,
- Circular, Normal or peripheral flow control mode, Channel Priority level,
- Source and Destination Increment mode using HAL_DMA_Init() function.
-
- *** Polling mode IO operation ***
- =================================
- [..]
- (+) Use HAL_DMA_Start() to start DMA transfer after the configuration of Source
- address and destination address and the Length of data to be transferred
- (+) Use HAL_DMA_PollForTransfer() to poll for the end of current transfer, in this
- case a fixed Timeout can be configured by User depending from his application.
-
- *** Interrupt mode IO operation ***
- ===================================
- [..]
- (+) Configure the DMA interrupt priority using HAL_NVIC_SetPriority()
- (+) Enable the DMA IRQ handler using HAL_NVIC_EnableIRQ()
- (+) Use HAL_DMA_Start_IT() to start DMA transfer after the configuration of
- Source address and destination address and the Length of data to be transferred. In this
- case the DMA interrupt is configured
- (+) Use HAL_DMA_IRQHandler() called under DMA_IRQHandler() Interrupt subroutine
- (+) At the end of data transfer HAL_DMA_IRQHandler() function is executed and user can
- add his own function by customization of function pointer XferCpltCallback and
- XferErrorCallback (i.e a member of DMA handle structure).
-
- (#) Use HAL_DMA_GetState() function to return the DMA state and HAL_DMA_GetError() in case of error
- detection.
-
- (#) Use HAL_DMA_Abort() function to abort the current transfer
-
- -@- In Memory-to-Memory transfer mode, Circular mode is not allowed.

- * @author MCD Application Team
- * @version V1.1.0
- * @date 18-June-2014
- * @brief FLASH HAL module driver.
- * This file provides firmware functions to manage the following
- * functionalities of the internal FLASH memory:
- * + FLASH Interface configuration
- * + FLASH Memory Programming
- * + DATA EEPROM Programming
- * + Option Bytes Programming
- * + Interrupts and flags management
- *
- * @verbatim
-
- ==============================================================================
- ##### FLASH peripheral features #####
- ==============================================================================
-
- [..] The Flash memory interface manages CPU accesses to the Flash memory.
- It implements the erase and program Flash memory operations
- and the read and write protection mechanisms.
-
- [..] The FLASH main features are:
- (+) Flash memory read operations
- (+) Flash memory program/erase operations
- (+) Read / write protections
- (+) Option Bytes programming
-
- ##### How to use this driver #####
- ==============================================================================
- [..]
- This driver provides functions and macros to configure and program the FLASH
- memory of all STM32L0xx devices.
-
- (#) FLASH Memory IO Programming functions:
- (++) Lock and Unlock the FLASH interface using HAL_FLASH_Unlock() and
- HAL_FLASH_Lock() functions
- (++) Program functions: byte, half word and word
- (++) There Two modes of programming :
- (+++) Polling mode using HAL_FLASH_Program() function
- (+++) Interrupt mode using HAL_FLASH_Program_IT() function
-
- (#) Interrupts and flags management functions :
- (++) Handle FLASH interrupts by calling HAL_FLASH_IRQHandler()
- (++) Wait for last FLASH operation according to its status
- (++) Get error flag status by calling HAL_GetErrorCode()
-
- [..]
- In addition to these functions, this driver includes a set of macros allowing
- to handle the following operations:
- (+) Set the latency
- (+) Enable/Disable the prefetch buffer
- (+) Enable/Disable the preread buffer
- (+) Enable/Disable the Flash power-down
- (+) Enable/Disable the FLASH interrupts
- (+) Monitor the FLASH flags status
-
- ===============================================================================
- ##### Programming operation functions #####
- ===============================================================================
- [..]
- This subsection provides a set of functions allowing to manage the FLASH
- program operations.
-
- [..] The FLASH Memory Programming functions, includes the following functions:
- (+) HAL_FLASH_Unlock(void);
- (+) HAL_FLASH_Lock(void);
- (+) HAL_FLASH_Program(uint32_t TypeProgram, uint32_t Address, uint32_t Data)
- (+) HAL_FLASH_Program_IT(uint32_t TypeProgram, uint32_t Address, uint32_t Data)
-
- [..] Any operation of erase or program should follow these steps:
- (#) Call the HAL_FLASH_Unlock() function to enable the flash control register and
- program memory access.
- (#) Call the desired function to erase page or program data.
- (#) Call the HAL_FLASH_Lock() to disable the flash program memory access
- (recommended to protect the FLASH memory against possible unwanted operation).
-
- ==============================================================================
- ##### Option Bytes Programming functions #####
- ==============================================================================
-
- [..] The FLASH_Option Bytes Programming_functions, includes the following functions:
- (+) HAL_FLASH_OB_Unlock(void);
- (+) HAL_FLASH_OB_Lock(void);
- (+) HAL_FLASH_OB_Launch(void);
- (+) HAL_FLASHEx_OBProgram(FLASH_OBProgramInitTypeDef *pOBInit);
- (+) HAL_FLASHEx_OBGetConfig(FLASH_OBProgramInitTypeDef *pOBInit);
-
- [..] Any operation of erase or program should follow these steps:
- (#) Call the HAL_FLASH_OB_Unlock() function to enable the Flash option control
- register access.
- (#) Call the following functions to program the desired option bytes.
- (++) HAL_FLASHEx_OBProgram(FLASH_OBProgramInitTypeDef *pOBInit);
- (#) Once all needed option bytes to be programmed are correctly written, call the
- HAL_FLASH_OB_Launch(void) function to launch the Option Bytes programming process.
- (#) Call the HAL_FLASH_OB_Lock() to disable the Flash option control register access (recommended
- to protect the option Bytes against possible unwanted operations).
-
- [..] Proprietary code Read Out Protection (PcROP):
- (#) The PcROP sector is selected by using the same option bytes as the Write
- protection (nWRPi bits). As a result, these 2 options are exclusive each other.
- (#) In order to activate the PcROP (change the function of the nWRPi option bits),
- the SPRMOD option bit must be activated.
- (#) The active value of nWRPi bits is inverted when PCROP mode is active, this
- means: if SPRMOD = 1 and nWRPi = 1 (default value), then the user page "i"
- is read/write protected.
- (#) To activate PCROP mode for Flash page(s), you need to follow the sequence below:
- (++) For page(s) within the first 64KB of the Flash, use this function
- HAL_FLASHEx_AdvOBProgram with PCROPState = PCROPSTATE_ENABLE.

- * @brief GPIO HAL module driver.
- * This file provides firmware functions to manage the following
- * functionalities of the General Purpose Input/Output (GPIO) peripheral:
- * + Initialization and de-initialization functions
- * + IO operation functions
- *
- @verbatim
- ==============================================================================
- ##### GPIO Peripheral features #####
- ==============================================================================
- [..]
- (+) Each port bit of the general-purpose I/O (GPIO) ports can be individually
- configured by software in several modes:
- (++) Input mode
- (++) Analog mode
- (++) Output mode
- (++) Alternate function mode
- (++) External interrupt/event lines
-
- (+) During and just after reset, the alternate functions and external interrupt
- lines are not active and the I/O ports are configured in input floating mode.
-
- (+) All GPIO pins have weak internal pull-up and pull-down resistors, which can be
- activated or not.
-
- (+) In Output or Alternate mode, each IO can be configured on open-drain or push-pull
- type and the IO speed can be selected depending on the VDD value.
-
- (+) The microcontroller IO pins are connected to onboard peripherals/modules through a
- multiplexer that allows only one peripheral alternate function (AF) connected
- to an IO pin at a time. In this way, there can be no conflict between peripherals
- sharing the same IO pin.
-
- (+) All ports have external interrupt/event capability. To use external interrupt
- lines, the port must be configured in input mode. All available GPIO pins are
- connected to the 16 external interrupt/event lines from EXTI0 to EXTI15.
-
- (+) The external interrupt/event controller consists of up to 23 edge detectors
- (16 lines are connected to GPIO) for generating event/interrupt requests (each
- input line can be independently configured to select the type (interrupt or event)
- and the corresponding trigger event (rising or falling or both). Each line can
- also be masked independently.
-
- ##### How to use this driver #####
- ==============================================================================
- [..]
- (#) Enable the GPIO IOPORT clock using the following function: __GPIOx_CLK_ENABLE().
-
- (#) In case of external interrupt/event mode selection, enable the SYSCFG clock
- using the following function __SYSCFG_CLK_ENABLE().
-
- (#) Configure the GPIO pin(s) using HAL_GPIO_Init().
- (++) Configure the IO mode using "Mode" member from GPIO_InitTypeDef structure
- (++) Activate Pull-up, Pull-down resistor using "Pull" member from GPIO_InitTypeDef
- structure.
- (++) In case of Output or alternate function mode selection: the speed is
- configured through "Speed" member from GPIO_InitTypeDef structure.
- (++) In alternate mode is selection, the alternate function connected to the IO
- is configured through "Alternate" member from GPIO_InitTypeDef structure.
- (++) Analog mode is required when a pin is to be used as ADC channel
- or DAC output.
- (++) In case of external interrupt/event selection the "Mode" member from
- GPIO_InitTypeDef structure select the type (interrupt or event) and
- the corresponding trigger event (rising or falling or both).
-
- (#) In case of external interrupt/event mode selection, configure NVIC IRQ priority
- mapped to the EXTI line using HAL_NVIC_SetPriority() and enable it using
- HAL_NVIC_EnableIRQ().
-
- (#) To get the level of a pin configured in input mode use HAL_GPIO_ReadPin().
-
- (#) To set/reset the level of a pin configured in output mode use
- HAL_GPIO_WritePin()/HAL_GPIO_TogglePin().
-
- (#) During and just after reset, the alternate functions are not
- active and the GPIO pins are configured in input floating mode (except JTAG
- pins).
-
- (#) The LSE oscillator pins OSC32_IN and OSC32_OUT can be used as general purpose
- (PC14 and PC15, respectively) when the LSE oscillator is off. The LSE has
- priority over the GPIO function.
-
- (#) The HSE oscillator pins OSC_IN/OSC_OUT can be used as
- general purpose PH0 and PH1, respectively, when the HSE oscillator is off.
- The HSE has priority over the GPIO function.

- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..]
- The I2C HAL driver can be used as follows:
-
- (#) Declare a I2C_HandleTypeDef handle structure, for example:
- I2C_HandleTypeDef hi2c;
-
- (#)Initialize the I2C low level resources by implement the HAL_I2C_MspInit ()API:
- (##) Enable the I2Cx interface clock
- (##) I2C pins configuration
- (+++) Enable the clock for the I2C GPIOs
- (+++) Configure I2C pins as alternate function open-drain
- (##) NVIC configuration if you need to use interrupt process
- (+++) Configure the I2Cx interrupt priority
- (+++) Enable the NVIC I2C IRQ Channel
- (##) DMA Configuration if you need to use DMA process
- (+++) Declare a DMA_HandleTypeDef handle structure for the transmit or receive stream
- (+++) Enable the DMAx interface clock using
- (+++) Configure the DMA handle parameters
- (+++) Configure the DMA Tx or Rx Stream
- (+++) Associate the initilalized DMA handle to the hi2c DMA Tx or Rx handle
- (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx or Rx Stream
-
- (#) Configure the Communication Clock Timing, Own Address1, Master Adressing Mode, Dual Addressing mode,
- Own Address2, Own Address2 Mask, General call and Nostretch mode in the hi2c Init structure.
-
- (#) Initialize the I2C registers by calling the HAL_I2C_Init() API:
- (+++) These API's configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)

- * @brief I2S HAL module driver.
- *
- * This file provides firmware functions to manage the following
- * functionalities of the Integrated Interchip Sound (I2S) peripheral:
- * + Initialization and de-initialization functions
- * + IO operation functions
- * + Peripheral State and Errors functions
- @verbatim
- ===============================================================================
- ##### How to use this driver #####
- ===============================================================================
- [..]
- The I2S HAL driver can be used as follow:
-
- (#) Declare a I2S_HandleTypeDef handle structure.
- (#) Initialize the I2S low level resources by implement the HAL_I2S_MspInit() API:
- (##) Enable the SPIx interface clock.
- (##) I2S pins configuration:
- (+++) Enable the clock for the I2S GPIOs.
- (+++) Configure these I2S pins as alternate function pull-up.
- (##) NVIC configuration if you need to use interrupt process (HAL_I2S_Transmit_IT()
- and HAL_I2S_Receive_IT() APIs).
- (+++) Configure the I2Sx interrupt priority.
- (+++) Enable the NVIC I2S IRQ handle.
- (##) DMA Configuration if you need to use DMA process (HAL_I2S_Transmit_DMA()
- and HAL_I2S_Receive_DMA() APIs:
- (+++) Declare a DMA handle structure for the Tx/Rx stream.
- (+++) Enable the DMAx interface clock.
- (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.
- (+++) Configure the DMA Tx/Rx Stream.
- (+++) Associate the initilalized DMA handle to the I2S DMA Tx/Rx handle.
- (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the
- DMA Tx/Rx Stream.
-
- (#) Program the Mode, Standard, Data Format, MCLK Output, Audio frequency and Polarity
- using HAL_I2S_Init() function.
-
- -@- The specific I2S interrupts (Transmission complete interrupt,
- RXNE interrupt and Error Interrupts) will be managed using the macros
- __I2S_ENABLE_IT() and __I2S_DISABLE_IT() inside the transmit and receive process.
- (#) Three mode of operations are available within this driver :
-
- *** Polling mode IO operation ***
- =================================
- [..]
- (+) Send an amount of data in blocking mode using HAL_I2S_Transmit()
- (+) Receive an amount of data in blocking mode using HAL_I2S_Receive()
-
- *** Interrupt mode IO operation ***
- ===================================
- [..]
- (+) Send an amount of data in non blocking mode using HAL_I2S_Transmit_IT()
- (+) At transmission end of transfer HAL_I2S_TxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_I2S_TxCpltCallback
- (+) Receive an amount of data in non blocking mode using HAL_I2S_Receive_IT()
- (+) At reception end of transfer HAL_I2S_RxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_I2S_RxCpltCallback
- (+) In case of transfer Error, HAL_I2S_ErrorCallback() function is executed and user can
- add his own code by customization of function pointer HAL_I2S_ErrorCallback
-
- *** DMA mode IO operation ***
- ==============================
- [..]
- (+) Send an amount of data in non blocking mode (DMA) using HAL_I2S_Transmit_DMA()
- (+) At transmission end of half transfer HAL_I2S_TxHalfCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_I2S_TxHalfCpltCallback
- (+) At transmission end of transfer HAL_I2S_TxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_I2S_TxCpltCallback
- (+) Receive an amount of data in non blocking mode (DMA) using HAL_I2S_Receive_DMA()
- (+) At reception end of half transfer HAL_I2S_RxHalfCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_I2S_RxHalfCpltCallback
- (+) At reception end of transfer HAL_I2S_RxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_I2S_RxCpltCallback
- (+) In case of transfer Error, HAL_I2S_ErrorCallback() function is executed and user can
- add his own code by customization of function pointer HAL_I2S_ErrorCallback
- (+) Pause the DMA Transfer using HAL_I2S_DMAPause()
- (+) Resume the DMA Transfer using HAL_I2S_DMAResume()
- (+) Stop the DMA Transfer using HAL_I2S_DMAStop()
-
- *** I2S HAL driver macros list ***
- ===================================
- [..]
- Below the list of most used macros in USART HAL driver.
-
- (+) __HAL_I2S_ENABLE: Enable the specified SPI peripheral (in I2S mode)
- (+) __HAL_I2S_DISABLE: Disable the specified SPI peripheral (in I2S mode)
- (+) __HAL_I2S_ENABLE_IT : Enable the specified I2S interrupts
- (+) __HAL_I2S_DISABLE_IT : Disable the specified I2S interrupts
- (+) __HAL_I2S_GET_FLAG: Check whether the specified I2S flag is set or not
-
- [..]
- (@) You can refer to the I2S HAL driver header file for more useful macros

- ##### IO operation functions #####

- [..]
- This subsection provides a set of functions allowing to manage the I2S data
- transfers.
-
- (#) There is two mode of transfer:
- (++) Blocking mode : The communication is performed in the polling mode.
- The status of all data processing is returned by the same function
- after finishing transfer.
- (++) No-Blocking mode : The communication is performed using Interrupts
- or DMA. These functions return the status of the transfer startup.
- The end of the data processing will be indicated through the
- dedicated I2S IRQ when using Interrupt mode or the DMA IRQ when
- using DMA mode.
-
- (#) Blocking mode functions are :
- (++) HAL_I2S_Transmit()
- (++) HAL_I2S_Receive()
-
- (#) No-Blocking mode functions with Interrupt are :
- (++) HAL_I2S_Transmit_IT()
- (++) HAL_I2S_Receive_IT()
-
- (#) No-Blocking mode functions with DMA are :
- (++) HAL_I2S_Transmit_DMA()
- (++) HAL_I2S_Receive_DMA()
-
- (#) A set of Transfer Complete Callbacks are provided in No_Blocking mode:
- (++) HAL_I2S_TxCpltCallback()
- (++) HAL_I2S_RxCpltCallback()
- (++) HAL_I2S_ErrorCallback()

- * @brief IRDA HAL module driver.
- *
- * This file provides firmware functions to manage the following
- * functionalities of the IrDA (Infrared Data Association) Peripheral
- * (IRDA)
- * + Initialization and de-initialization functions
- * + IO operation functions
- * + Peripheral Control functions
- *
- *
- @verbatim
- ===============================================================================
- ##### How to use this driver #####
- ===============================================================================
- [..]
- The IRDA HAL driver can be used as follows:
-
-
- (#) Declare a IRDA_HandleTypeDef handle structure.
- (#) Initialize the IRDA low level resources by implementing the HAL_IRDA_MspInit() API:
- (##) Enable the USARTx interface clock.
- (##) IRDA pins configuration:
- (+) Enable the clock for the IRDA GPIOs.
- (+) Configure these IRDA pins as alternate function pull-up.
- (##) NVIC configuration if you need to use interrupt process (HAL_IRDA_Transmit_IT()
- and HAL_IRDA_Receive_IT() APIs):
- (+) Configure the USARTx interrupt priority.
- (+) Enable the NVIC USART IRQ handle.
- (##) DMA Configuration if you need to use DMA process (HAL_IRDA_Transmit_DMA()
- and HAL_IRDA_Receive_DMA() APIs):
- (+) Declare a DMA handle structure for the Tx/Rx channel.
- (+) Enable the DMAx interface clock.
- (+) Configure the declared DMA handle structure with the required Tx/Rx parameters.
- (+) Configure the DMA Tx/Rx channel.
- (+) Associate the initilalized DMA handle to the IRDA DMA Tx/Rx handle.
- (+) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx channel.
-
- (#) Program the Baud Rate, Word Length, Parity, IrDA Mode, Prescaler
- and Mode(Receiver/Transmitter) in the hirda Init structure.
-
- (#) Initialize the IRDA registers by calling the HAL_IRDA_Init() API:
- (++) This API configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
- by calling the customed HAL_IRDA_MspInit() API.
- -@@- The specific IRDA interrupts (Transmission complete interrupt,
- RXNE interrupt and Error Interrupts) will be managed using the macros
- __HAL_IRDA_ENABLE_IT() and __HAL_IRDA_DISABLE_IT() inside the transmit and receive process.
-
- (#) Three operation modes are available within this driver :
-
- *** Polling mode IO operation ***
- =================================
- [..]
- (+) Send an amount of data in blocking mode using HAL_IRDA_Transmit()
- (+) Receive an amount of data in blocking mode using HAL_IRDA_Receive()
-
- *** Interrupt mode IO operation ***
- ===================================
- [..]
- (+) Send an amount of data in non blocking mode using HAL_IRDA_Transmit_IT()
- (+) At transmission end of transfer HAL_IRDA_TxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_IRDA_TxCpltCallback
- (+) Receive an amount of data in non blocking mode using HAL_IRDA_Receive_IT()
- (+) At reception end of transfer HAL_IRDA_RxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_IRDA_RxCpltCallback
- (+) In case of transfer Error, HAL_IRDA_ErrorCallback() function is executed and user can
- add his own code by customization of function pointer HAL_IRDA_ErrorCallback
-
- *** DMA mode IO operation ***
- =============================
- [..]
- (+) Send an amount of data in non blocking mode (DMA) using HAL_IRDA_Transmit_DMA()
- (+) At transmission end of transfer HAL_IRDA_TxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_IRDA_TxCpltCallback
- (+) Receive an amount of data in non blocking mode (DMA) using HAL_IRDA_Receive_DMA()
- (+) At reception end of transfer HAL_IRDA_RxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_IRDA_RxCpltCallback
- (+) In case of transfer Error, HAL_IRDA_ErrorCallback() function is executed and user can
- add his own code by customization of function pointer HAL_IRDA_ErrorCallback
-
- *** IRDA HAL driver macros list ***
- ===================================
- [..]
- Below the list of most used macros in IRDA HAL driver.
-
- (+) __HAL_IRDA_ENABLE: Enable the IRDA peripheral
- (+) __HAL_IRDA_DISABLE: Disable the IRDA peripheral
- (+) __HAL_IRDA_GET_FLAG : Checks whether the specified IRDA flag is set or not
- (+) __HAL_IRDA_CLEAR_FLAG : Clears the specified IRDA pending flag
- (+) __HAL_IRDA_ENABLE_IT: Enables the specified IRDA interrupt
- (+) __HAL_IRDA_DISABLE_IT: Disables the specified IRDA interrupt
-
- (@) You can refer to the IRDA HAL driver header file for more useful macros

- ##### Initialization and Configuration functions #####
- ===============================================================================
- [..]
- This subsection provides a set of functions allowing to initialize the USARTx
- in asynchronous IRDA mode.
- (+) For the asynchronous mode only these parameters can be configured:
- (++) Baud Rate
- (++) Word Length
- (++) Parity: If the parity is enabled, then the MSB bit of the data written
- in the data register is transmitted but is changed by the parity bit.
- Depending on the frame length defined by the M bit (8-bits or 9-bits)
- or by the M1 and M0 bits (7-bit, 8-bit or 9-bit),
- the possible IRDA frame formats are as listed in the following table:
- +---------------------------------------------------------------+
- | M1M0 bits | PCE bit | IRDA frame |
- |-----------|-----------|---------------------------------------|
- | 00 | 0 | | SB | 8-bit data | STB | |
- |-----------|-----------|---------------------------------------|
- | 00 | 1 | | SB | 7-bit data | PB | STB | |
- |-----------|-----------|---------------------------------------|
- | 01 | 0 | | SB | 9-bit data | STB | |
- |-----------|-----------|---------------------------------------|
- | 01 | 1 | | SB | 8-bit data | PB | STB | |
- |-----------------------|---------------------------------------|
- | 10 | 0 | | SB | 7-bit data | STB | |
- |-----------|-----------|---------------------------------------|
- | 10 | 1 | | SB | 6-bit data | PB | STB | |
- +---------------------------------------------------------------+
-
- (++) Power mode
- (++) Prescaler setting
- (++) Receiver/transmitter modes
-
- [..]
- The HAL_IRDA_Init() API follows the USART asynchronous configuration procedures
- (details for the procedures are available in reference manual).

- or DMA, these API's return the HAL status.
- The end of the data processing will be indicated through the
- dedicated IRDA IRQ when using Interrupt mode or the DMA IRQ when
- using DMA mode.
- The HAL_IRDA_TxCpltCallback(), HAL_IRDA_RxCpltCallback() user callbacks
- will be executed respectivelly at the end of the Transmit or Receive process

- * @brief IWDG HAL module driver.
- * This file provides firmware functions to manage the following
- * functionalities of the Independent Watchdog (IWDG) peripheral:
- * + Initialization and de-initialization functions
- * + IO operation functions
- * + Peripheral State functions
- *
- @verbatim
- ==============================================================================
- ##### IWDG Generic features #####
- ==============================================================================
- [..]
- (+) The IWDG can be started by either software or hardware (configurable
- through option byte).
-
- (+) The IWDG is clocked by its own dedicated Low-Speed clock (LSI) and
- thus stays active even if the main clock fails.
- Once the IWDG is started, the LSI is forced ON and cannot be disabled
- (LSI cannot be disabled too), and the counter starts counting down from
- the reset value of 0xFFF. When it reaches the end of count value (0x000)
- a system reset is generated.
-
- (+) The IWDG counter should be refreshed at regular intervals, otherwise the
- watchdog generates an MCU reset when the counter reaches 0.
-
- (+) The IWDG is implemented in the VDD voltage domain that is still functional
- in STOP and STANDBY mode (IWDG reset can wake-up from STANDBY).
- IWDGRST flag in RCC_CSR register can be used to inform when an IWDG
- reset occurs.
-
- [..] Min-max timeout value @32KHz (LSI): ~0.512ms / ~32.0s
- The IWDG timeout may vary due to LSI frequency dispersion. STM32L0xx
- devices provide the capability to measure the LSI frequency (LSI clock
- connected internally to TIM5 CH4 input capture). The measured value
- can be used to have an IWDG timeout with an acceptable accuracy.
-
-
- ##### How to use this driver #####
- ==============================================================================
- [..]
- If Window option is disabled
-
- (+) Use IWDG using HAL_IWDG_Init() function to :
- (++) Enable write access to IWDG_PR, IWDG_RLR.
- (++) Configure the IWDG prescaler, counter reload value.
- This reload value will be loaded in the IWDG counter each time the counter
- is reloaded, then the IWDG will start counting down from this value.
- (+) Use IWDG using HAL_IWDG_Start() function to :
- (++) Reload IWDG counter with value defined in the IWDG_RLR register.
- (++) Start the IWDG, when the IWDG is used in software mode (no need
- to enable the LSI, it will be enabled by hardware).
- (+) Then the application program must refresh the IWDG counter at regular
- intervals during normal operation to prevent an MCU reset, using
- HAL_IWDG_Refresh() function.
- [..]
- if Window option is enabled:
-
- (+) Use IWDG using HAL_IWDG_Start() function to enable IWDG downcounter
- (+) Use IWDG using HAL_IWDG_Init() function to :
- (++) Enable write access to IWDG_PR, IWDG_RLR and IWDG_WINR registers.
- (++) Configure the IWDG prescaler, reload value and window value.
- (+) Then the application program must refresh the IWDG counter at regular
- intervals during normal operation to prevent an MCU reset, using
- HAL_IWDG_Refresh() function.
-
- *** IWDG HAL driver macros list ***
- ====================================
- [..]
- Below the list of most used macros in IWDG HAL driver.
-
- (+) __HAL_IWDG_START: Enable the IWDG peripheral
- (+) __HAL_IWDG_RELOAD_COUNTER: Reloads IWDG counter with value defined in the reload register
- (+) __HAL_IWDG_ENABLE_WRITE_ACCESS : Enable write access to IWDG_PR and IWDG_RLR registers
- (+) __HAL_IWDG_DISABLE_WRITE_ACCESS : Disable write access to IWDG_PR and IWDG_RLR registers
- (+) __HAL_IWDG_GET_FLAG: Get the selected IWDG's flag status

- * This file provides firmware functions to manage the following
- * functionalities of the LCD Controller (LCD) peripheral:
- * + Initialization/de-initialization methods
- * + I/O operation methods
- * + Peripheral State methods
- *
- @verbatim
- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..] The LCD HAL driver can be used as follows:
-
- (#) Declare a LCD_HandleTypeDef handle structure.
-
- (#) Initialize the LCD low level resources by implement the HAL_LCD_MspInit() API:
- (##) Enable the LCDCLK (same as RTCCLK): to configure the RTCCLK/LCDCLK, proceed as follows:
- (+) Enable the Power Controller (PWR) APB1 interface clock using the
- __PWR_CLK_ENABLE() macro.
- (+) Enable access to RTC domain using the HAL_PWR_EnableBkUpAccess() function.
- (+) Select the RTC clock source using the __HAL_RCC_RTC_CONFIG() function.
-
- -@- The frequency generator allows you to achieve various LCD frame rates
- starting from an LCD input clock frequency (LCDCLK) which can vary
- from 32 kHz up to 1 MHz.
- (##) LCD pins configuration:
- (+) Enable the clock for the LCD GPIOs.
- (+) Configure these LCD pins as alternate function no-pull.
- (##) Enable the LCD interface clock.
-
- (#) Program the Prescaler, Divider, Blink mode, Blink Frequency Duty, Bias,
- Voltage Source, Dead Time, Pulse On Duration and Contrast in the hlcd Init structure.
-
- (#) Initialize the LCD registers by calling the HAL_LCD_Init() API.
-
- -@- The HAL_LCD_Init() API configures also the low level Hardware GPIO, CLOCK, ...etc)
- by calling the custumed HAL_LCD_MspInit() API.
- -@- After calling the HAL_LCD_Init() the LCD RAM memory is cleared
-
- (#) Optionally you can update the LCD configuration using these macros:
- (+) LCD High Drive using the __HAL_LCD_HIGHDRIVER_ENABLE() and __HAL_LCD_HIGHDRIVER_DISABLE() macros
- (+) LCD Pulse ON Duration using the __HAL_LCD_PULSEONDURATION_CONFIG() macro
- (+) LCD Dead Time using the __HAL_LCD_DEADTIME_CONFIG() macro
- (+) The LCD Blink mode and frequency using the __HAL_LCD_BLINK_CONFIG() macro
- (+) The LCD Contrast using the __HAL_LCD_CONTRAST_CONFIG() macro
-
- (#) Write to the LCD RAM memory using the HAL_LCD_Write() API, this API can be called
- more time to update the different LCD RAM registers before calling
- HAL_LCD_UpdateDisplayRequest() API.
-
- (#) The HAL_LCD_Clear() API can be used to clear the LCD RAM memory.
-
- (#) When LCD RAM memory is updated enable the update display request using
- the HAL_LCD_UpdateDisplayRequest() API.
-
- [..] LCD and low power modes:
- (#) The LCD remain active during STOP mode.

- ===============================================================================
- ##### IO operation functions #####
- ===============================================================================
- [..] Using its double buffer memory the LCD controller ensures the coherency of the
- displayed information without having to use interrupts to control LCD_RAM
- modification.
- The application software can access the first buffer level (LCD_RAM) through
- the APB interface. Once it has modified the LCD_RAM using the HAL_LCD_Write() API,
- it sets the UDR flag in the LCD_SR register using the HAL_LCD_UpdateDisplayRequest() API.
- This UDR flag (update display request) requests the updated information to be
- moved into the second buffer level (LCD_DISPLAY).
- This operation is done synchronously with the frame (at the beginning of the
- next frame), until the update is completed, the LCD_RAM is write protected and
- the UDR flag stays high.
- Once the update is completed another flag (UDD - Update Display Done) is set and
- generates an interrupt if the UDDIE bit in the LCD_FCR register is set.
- The time it takes to update LCD_DISPLAY is, in the worst case, one odd and one
- even frame.
- The update will not occur (UDR = 1 and UDD = 0) until the display is
- enabled (LCDEN = 1).

- ##### How to use this driver #####
- ==============================================================================
- [..]
- The LPTIM HAL driver can be used as follows:
-
- (#)Initialize the LPTIM low level resources by implementing the
- HAL_LPTIM_MspInit():
- (##) Enable the LPTIM interface clock using __LPTIM1_CLK_ENABLE().
- (##) In case of using interrupts (e.g. HAL_LPTIM_PWM_Start_IT()):
- (+) Configure the LPTIM interrupt priority using HAL_NVIC_SetPriority().
- (+) Enable the LPTIM IRQ handler using HAL_NVIC_EnableIRQ().
- (+) In LPTIM IRQ handler, call HAL_LPTIM_IRQHandler().
-
- (#)Initialize the LPTIM HAL using HAL_LPTIM_Init(). This function
- configures mainly:
- (##) The instance: Only LPTIM1 is present in STM32L053xx.
- (##) Clock: the counter clock.
- - Source : it can be either the ULPTIM input (IN1) or one of
- the internal clock; (APB, LSE, LSI or MSI).
- - Prescaler: select the clock divider.
- (##) UltraLowPowerClock : To be used only if the ULPTIM is selected
- as counter clock source.
- - Polarity: polarity of the active edge for the counter unit
- if the ULPTIM input is selected.
- - SampleTime: clock sampling time to configure the clock glitch
- filter.
- (##) Trigger: How the counter start.
- - Source: trigger can be software or one of the hardware triggers.
- - ActiveEdge : only for hardware trigger.
- - SampleTime : trigger sampling time to configure the trigger
- glitch filter.
- (##) OutputPolarity : 2 opposite polarities are possibles.
- (##) UpdateMode: specifies whether the update of the autoreload and
- the compare values is done immediately or after the end of current
- period.
-
- (#)Six modes are available:
-
- (##) PWM Mode: To generate a PWM signal with specified period and pulse,
- call HAL_LPTIM_PWM_Start() or HAL_LPTIM_PWM_Start_IT() for interruption
- mode.
-
- (##) One Pulse Mode: To generate pulse with specified width in response
- to a stimulus, call HAL_LPTIM_OnePulse_Start() or
- HAL_LPTIM_OnePulse_Start_IT() for interruption mode.
-
- (##) Set once Mode: In this mode, the output changes the level (from
- low level to high level if the output polarity is configured high, else
- the opposite) when a compare match occurs. To start this mode, call
- HAL_LPTIM_SetOnce_Start() or HAL_LPTIM_SetOnce_Start_IT() for
- interruption mode.
-
- (##) Encoder Mode: To use the encoder interface call
- HAL_LPTIM_Encoder_Start() or HAL_LPTIM_Encoder_Start_IT() for
- interruption mode.
-
- (##) Time out Mode: an active edge on one selected trigger input rests
- the counter. The first trigger event will start the timer, any
- successive trigger event will reset the counter and the timer will
- restart. To start this mode call HAL_LPTIM_TimeOut_Start_IT() or
- HAL_LPTIM_TimeOut_Start_IT() for interruption mode.
-
- (##) Counter Mode: counter can be used to count external events on
- the LPTIM Input1 or it can be used to count internal clock cycles.
- To start this mode, call HAL_LPTIM_Counter_Start() or
- HAL_LPTIM_Counter_Start_IT() for interruption mode.
-
-
- (#) User can stop any process by calling the corresponding API:
- HAL_LPTIM_Xxx_Stop() or HAL_LPTIM_Xxx_Stop_IT() if the process is
- already started in interruption mode.
-
- (#)Call HAL_LPTIM_DeInit() to deinitialize the LPTIM peripheral.

- ##### How to use this driver #####
- ==============================================================================
- [..]
- The PCD HAL driver can be used as follows:
-
- (#) Declare a PCD_HandleTypeDef handle structure, for example:
- PCD_HandleTypeDef hpcd;
-
- (#) Fill parameters of Init structure in HCD handle
-
- (#) Call HAL_PCD_Init() API to initialize the HCD peripheral (Core, Device core, ...)
-
- (#) Initialize the PCD low level resources through the HAL_PCD_MspInit() API:
- (##) Enable the PCD/USB Low Level interface clock using
- (+++) __USB_CLK_ENABLE;
-
- (##) Initialize the related GPIO clocks
- (##) Configure PCD pin-out
- (##) Configure PCD NVIC interrupt
-
- (#)Associate the Upper USB device stack to the HAL PCD Driver:
- (##) hpcd.pData = pdev;
-
- (#)Enable HCD transmission and reception:
- (##) HAL_PCD_Start();

- ===============================================================================
- ##### Peripheral Control functions #####
- ===============================================================================
-
- *** PVD configuration ***
- =========================
- [..]
- (+) The PVD is used to monitor the VDD power supply by comparing it to a
- threshold selected by the PVD Level (PLS[2:0] bits in the PWR_CR).
- (+) The PVD can use an external input analog voltage (PVD_IN) which is compared
- internally to VREFINT. The PVD_IN (PB7) has to be configured in Analog mode
- when PWR_PVDLevel_7 is selected (PLS[2:0] = 111).
-
- (+) A PVDO flag is available to indicate if VDD/VDDA is higher or lower
- than the PVD threshold. This event is internally connected to the EXTI
- line16 and can generate an interrupt if enabled. This is done through
- __HAL_PVD_EXTI_ENABLE_IT() macro.
- (+) The PVD is stopped in Standby mode.
-
- *** WakeUp pin configuration ***
- ================================
- [..]
- (+) WakeUp pin is used to wake up the system from Standby mode. This pin is
- forced in input pull-down configuration and is active on rising edges.
- (+) There are two WakeUp pins:
- WakeUp Pin 1 on PA.00.
- WakeUp Pin 2 on PC.13.
-
- [..]
- *** Main and Backup Regulators configuration ***
- ================================================
-
- (+) The main internal regulator can be configured to have a tradeoff between
- performance and power consumption when the device does not operate at
- the maximum frequency. This is done through __HAL_PWR_VOLTAGESCALING_CONFIG()
- macro which configure VOS bit in PWR_CR register:
- (++) When this bit is set (Regulator voltage output Scale 1 mode selected)
- the System frequency can go up to 32 MHz.
- (++) When this bit is reset (Regulator voltage output Scale 2 mode selected)
- the System frequency can go up to 16 MHz.
- (++) When this bit is reset (Regulator voltage output Scale 3 mode selected)
- the System frequency can go up to 4.2 MHz.
-
- Refer to the datasheets for more details.
-
- *** Low Power modes configuration ***
- =====================================
- [..]
- The device features 5 low-power modes:
- (+) Low power run mode: regulator in low power mode, limited clock frequency,
- limited number of peripherals running.
- (+) Sleep mode: Cortex-M0+ core stopped, peripherals kept running.
- (+) Low power sleep mode: Cortex-M0+ core stopped, limited clock frequency,
- limited number of peripherals running, regulator in low power mode.
- (+) Stop mode: All clocks are stopped, regulator running, regulator in low power mode.
- (+) Standby mode: VCORE domain powered off
-
- *** Low power run mode ***
- =========================
- [..]
- To further reduce the consumption when the system is in Run mode, the regulator can be
- configured in low power mode. In this mode, the system frequency should not exceed
- MSI frequency range1.
- In Low power run mode, all I/O pins keep the same state as in Run mode.
-
- (+) Entry:
- (++) VCORE in range2
- (++) Decrease the system frequency tonot exceed the frequency of MSI frequency range1.
- (++) The regulator is forced in low power mode using the HAL_PWREx_EnableLowPowerRunMode()
- function.
- (+) Exit:
- (++) The regulator is forced in Main regulator mode using the HAL_PWREx_DisableLowPowerRunMode()
- function.
- (++) Increase the system frequency if needed.
-
- *** Sleep mode ***
- ==================
- [..]
- (+) Entry:
- The Sleep mode is entered by using the HAL_PWR_EnterSLEEPMode(PWR_MAINREGULATOR_ON, PWR_SLEEPENTRY_WFx)
- functions with
- (++) PWR_SLEEPENTRY_WFI: enter SLEEP mode with WFI instruction
- (++) PWR_SLEEPENTRY_WFE: enter SLEEP mode with WFE instruction
-
- (+) Exit:
- (++) Any peripheral interrupt acknowledged by the nested vectored interrupt
- controller (NVIC) can wake up the device from Sleep mode.
-
- *** Low power sleep mode ***
- ============================
- [..]
- (+) Entry:
- The Low power sleep mode is entered by using the HAL_PWR_EnterSLEEPMode(PWR_LOWPOWERREGULATOR_ON, PWR_SLEEPENTRY_WFx)
- functions with
- (++) PWR_SLEEPENTRY_WFI: enter SLEEP mode with WFI instruction
- (++) PWR_SLEEPENTRY_WFE: enter SLEEP mode with WFE instruction
- (+) The Flash memory can be switched off by using the control bits (SLEEP_PD in the FLASH_ACR register.
- This reduces power consumption but increases the wake-up time.
-
- (+) Exit:
- (++) If the WFI instruction was used to enter Low power sleep mode, any peripheral interrupt
- acknowledged by the nested vectored interrupt controller (NVIC) can wake up the device
- from Low power sleep mode. If the WFE instruction was used to enter Low power sleep mode,
- the MCU exits Sleep mode as soon as an event occurs.
-
- *** Stop mode ***
- =================
- [..]
- The Stop mode is based on the Cortex-M0+ deepsleep mode combined with peripheral
- clock gating. The voltage regulator can be configured either in normal or low-power mode.
- In Stop mode, all clocks in the VCORE domain are stopped, the PLL, the MSI, the HSI and
- the HSE RC oscillators are disabled. Internal SRAM and register contents are preserved.
- To get the lowest consumption in Stop mode, the internal Flash memory also enters low
- power mode. When the Flash memory is in power-down mode, an additional startup delay is
- incurred when waking up from Stop mode.
- To minimize the consumption In Stop mode, VREFINT, the BOR, PVD, and temperature
- sensor can be switched off before entering Stop mode. They can be switched on again by
- software after exiting Stop mode using the ULP bit in the PWR_CR register.
- In Stop mode, all I/O pins keep the same state as in Run mode.
-
- (+) Entry:
- The Stop mode is entered using the HAL_PWR_EnterSTOPMode(PWR_MAINREGULATOR_ON, PWR_SLEEPENTRY_WFI )
- function with:
- (++) Main regulator ON.
- (++) Low Power regulator ON.
- (++) PWR_SLEEPENTRY_WFI: enter SLEEP mode with WFI instruction
- (++) PWR_SLEEPENTRY_WFE: enter SLEEP mode with WFE instruction
- (+) Exit:
- (++) By issuing an interrupt or a wakeup event, the MSI or HSI16 RC
- oscillator is selected as system clock depending the bit STOPWUCK in the RCC_CFGR
- register
-
- *** Standby mode ***
- ====================
- [..]
- The Standby mode allows to achieve the lowest power consumption. It is based on the
- Cortex-M0+ deepsleep mode, with the voltage regulator disabled. The VCORE domain is
- consequently powered off. The PLL, the MSI, the HSI oscillator and the HSE oscillator are
- also switched off. SRAM and register contents are lost except for the RTC registers, RTC
- backup registers and Standby circuitry.
-
- To minimize the consumption In Standby mode, VREFINT, the BOR, PVD, and temperature
- sensor can be switched off before entering the Standby mode. They can be switched
- on again by software after exiting the Standby mode.
- function.
-
- (+) Entry:
- (++) The Standby mode is entered using the HAL_PWR_EnterSTANDBYMode() function.
- (+) Exit:
- (++) WKUP pin rising edge, RTC alarm (Alarm A and Alarm B), RTC wakeup,
- tamper event, time-stamp event, external reset in NRST pin, IWDG reset.
-
- *** Auto-wakeup (AWU) from low-power mode ***
- =============================================
- [..]
- The MCU can be woken up from low-power mode by an RTC Alarm event, an RTC
- Wakeup event, a tamper event, a time-stamp event, or a comparator event,
- without depending on an external interrupt (Auto-wakeup mode).
-
- (+) RTC auto-wakeup (AWU) from the Stop mode
- (++) To wake up from the Stop mode with an RTC alarm event, it is necessary to:
- (+++) Configure the EXTI Line 17 to be sensitive to rising edges (Interrupt
- or Event modes) using the EXTI_Init() function.
- (+++) Enable the RTC Alarm Interrupt using the RTC_ITConfig() function
- (+++) Configure the RTC to generate the RTC alarm using the RTC_SetAlarm()
- and RTC_AlarmCmd() functions.
- (++) To wake up from the Stop mode with an RTC Tamper or time stamp event, it
- is necessary to:
- (+++) Configure the EXTI Line 19 to be sensitive to rising edges (Interrupt
- or Event modes) using the EXTI_Init() function.
- (+++) Enable the RTC Tamper or time stamp Interrupt using the RTC_ITConfig()
- function.
- (+++) Configure the RTC to detect the tamper or time stamp event using the
- RTC_TimeStampConfig(), RTC_TamperTriggerConfig() and RTC_TamperCmd()
- functions.
- (++) To wake up from the Stop mode with an RTC WakeUp event, it is necessary to:
- (+++) Configure the EXTI Line 20 to be sensitive to rising edges (Interrupt
- or Event modes) using the EXTI_Init() function.
- (+++) Enable the RTC WakeUp Interrupt using the RTC_ITConfig() function.
- (+++) Configure the RTC to generate the RTC WakeUp event using the RTC_WakeUpClockConfig(),
- RTC_SetWakeUpCounter() and RTC_WakeUpCmd() functions.
-
- (+) RTC auto-wakeup (AWU) from the Standby mode
- (++) To wake up from the Standby mode with an RTC alarm event, it is necessary to:
- (+++) Enable the RTC Alarm Interrupt using the RTC_ITConfig() function.
- (+++) Configure the RTC to generate the RTC alarm using the RTC_SetAlarm()
- and RTC_AlarmCmd() functions.
- (++) To wake up from the Standby mode with an RTC Tamper or time stamp event, it
- is necessary to:
- (+++) Enable the RTC Tamper or time stamp Interrupt using the RTC_ITConfig()
- function.
- (+++) Configure the RTC to detect the tamper or time stamp event using the
- RTC_TimeStampConfig(), RTC_TamperTriggerConfig() and RTC_TamperCmd()
- functions.
- (++) To wake up from the Standby mode with an RTC WakeUp event, it is necessary to:
- (+++) Enable the RTC WakeUp Interrupt using the RTC_ITConfig() function
- (+++) Configure the RTC to generate the RTC WakeUp event using the RTC_WakeUpClockConfig(),
- RTC_SetWakeUpCounter() and RTC_WakeUpCmd() functions.
-
- (+) Comparator auto-wakeup (AWU) from the Stop mode
- (++) To wake up from the Stop mode with an comparator 1 or comparator 2 wakeup
- event, it is necessary to:
- (+++) Configure the EXTI Line 21 for comparator 1 or EXTI Line 22 for comparator 2
- to be sensitive to to the selected edges (falling, rising or falling
- and rising) (Interrupt or Event modes) using the EXTI_Init() function.
- (+++) Configure the comparator to generate the event.

- [..] Once the device started from reset, the user application has to:
- (+) Configure the clock source to be used to drive the System clock
- (if the application needs higher frequency/performance)
- (+) Configure the System clock frequency and Flash settings
- (+) Configure the AHB and APB busses prescalers

- ===============================================================================
- [..]
- This section provide functions allowing to configure the internal/external
- clocks, PLL, CSS and MCO.
- [..] Internal/external clock and PLL configuration
- (#) HSI (high-speed internal), 16 MHz factory-trimmed RC used directly
- or through the PLL as System clock source.
- (#) MSI (multi-speed internal), multispeed low power RC
- (65.536 KHz to 4.194 MHz) MHz used as System clock source.
- (#) LSI (low-speed internal), 37 KHz low consumption RC used as IWDG
- and/or RTC clock source.
- (#) HSE (high-speed external), 1 to 24 MHz crystal oscillator used
- directly or through the PLL as System clock source. Can be used
- also as RTC clock source.
- (#) LSE (low-speed external), 32 KHz oscillator used as RTC clock source.
- (#) PLL (clocked by HSI or HSE), for System clock and USB (48 MHz).
- (#) CSS (Clock security system), once enable and if a HSE clock failure
- occurs (HSE used directly or through PLL as System clock source),
- the System clock is automatically switched to MSI and an interrupt
- is generated if enabled.
- The interrupt is linked to the Cortex-M3 NMI (Non-Maskable Interrupt)
- exception vector.
- (#) MCO (microcontroller clock output), used to output SYSCLK, HSI, MSI,
- HSE, PLL, LSI or LSE clock (through a configurable prescaler) on
- PA8 pin.
- [..] System, AHB and APB busses clocks configuration
- (#) Several clock sources can be used to drive the System clock (SYSCLK): MSI, HSI,
- HSE and PLL.
- The AHB clock (HCLK) is derived from System clock through configurable
- prescaler and used to clock the CPU, memory and peripherals mapped
- on IOPORT, AHB bus (DMA,Flash...). APB1 (PCLK1) and APB2 (PCLK2) clocks are derived
- from AHB clock through configurable prescalers and used to clock
- the peripherals mapped on these busses. You can use
- "HAL_RCC_GetSysClockFreq()" function to retrieve the frequencies of these clocks.
-
- -@- All the peripheral clocks are derived from the System clock (SYSCLK) except:
- (+@) I2S: the I2S clock can be derived from an external clock mapped on the I2S_CKIN pin.
-
- (+@) RTC: the RTC clock can be derived either from the LSI, LSE or HSE clock
- divided by 2 to 16. You have to use __HAL_RCC_RTC_CONFIG() and __HAL_RCC_RTC_ENABLE()
- macros to configure this clock.
- (+@) USB FS,and RNG require a frequency equal to 48 MHz to work correctly
- This clock is derived from the main PLL or HSI48 RC oscillator.
- (+@) IWDG clock which is always the LSI clock.
-
- (#) For the STM32L0xx devices, the maximum
- frequency of the SYSCLK ,HCLK, APB1 and APB2 is 32 MHz.
- Depending on the device voltage range, the maximum frequency should
- be adapted accordingly:
- ----------------------------------------------------------------
- | Wait states | HCLK clock frequency (MHz) |
- | |------------------------------------------------|
- | (Latency) | voltage range | voltage range |
- | | 1.65 V - 3.6 V | 2.0 V - 3.6 V |
- | |----------------|---------------|---------------|
- | | VCORE = 1.2 V | VCORE = 1.5 V | VCORE = 1.8 V |
- |-------------- |----------------|---------------|---------------|
- |0WS(1CPU cycle)|0 < HCLK <= 2 |0 < HCLK <= 8 |0 < HCLK <= 16 |
- |---------------|----------------|---------------|---------------|
- |1WS(2CPU cycle)|2 < HCLK <= 4 |8 < HCLK <= 16 |16 < HCLK <= 32|

- * @brief Extended RCC HAL module driver.
- *
- * This file provides firmware functions to manage the following
- * functionalities RCC extension peripheral:
- * + Extended Peripheral Control functions
- *
- @verbatim
- ==============================================================================
- ##### RCC specific features #####
- ==============================================================================
- For CRS, RCC Extension HAL driver can be used as follows:
-
- (#) In System clock configuration, HSI48 need to be enabled
-
- (#] Enable CRS clock in IP MSP init which will use CRS functions
-
- (#) Call CRS functions like this
- (##) Prepare synchronization configuration necessary for HSI48 calibration
- (+++) Default values can be set for frequency Error Measurement (reload and error limit)
- and also HSI48 oscillator smooth trimming.
- (+++) Macro __HAL_RCC_CRS_CALCULATE_RELOADVALUE can be also used to calculate
- directly reload value with target and synchronization frequencies values
- (##) Call function HAL_RCCEx_CRSConfig which
- (+++) Reset CRS registers to their default values.
- (+++) Configure CRS registers with synchronization configuration
- (+++) Enable automatic calibration and frequency error counter feature
-
- (##) A polling function is provided to wait for complete Synchronization
- (+++) Call function 'HAL_RCCEx_CRSWaitSynchronization()'
- (+++) According to CRS status, user can decide to adjust again the calibration or continue
- application if synchronization is OK
-
- (#) User can retrieve information related to synchronization in calling function
- HAL_RCCEx_CRSGetSynchronizationInfo()
-
- (#) Regarding synchronization status and synchronization information, user can try a new calibration
- in changing synchronization configuration and call again HAL_RCCEx_CRSConfig.
- Note: When the SYNC event is detected during the downcounting phase (before reaching the zero value),
- it means that the actual frequency is lower than the target (and so, that the TRIM value should be
- incremented), while when it is detected during the upcounting phase it means that the actual frequency
- is higher (and that the TRIM value should be decremented).
-
- (#) To use IT mode, user needs to handle it in calling different macros available to do it
- (__HAL_RCC_CRS_XXX_IT). Interruptions will go through RCC Handler (RCC_IRQn/RCC_CRS_IRQHandler)
- (+++) Call function HAL_RCCEx_CRSConfig()
- (+++) Enable RCC_IRQn (thnaks to NVIC functions)
- (+++) Enable CRS IT (__HAL_RCC_CRS_ENABLE_IT)
- [+++) Implement CRS status management in RCC_CRS_IRQHandler
-
- (#) To force a SYNC EVENT, user can use function 'HAL_RCCEx_CRSSoftwareSynchronizationGenerate()'. Function can be
- called before calling HAL_RCCEx_CRSConfig (for instance in Systick handler)

- * @brief RTC HAL module driver.
- * This file provides firmware functions to manage the following
- * functionalities of the Real Time Clock (RTC) peripheral:
- * + Initialization/de-initialization functions
- * + I/O operation functions
- * + Peripheral Control functions
- * + Peripheral State functions
- *
- @verbatim
- ==============================================================================
- ##### Backup Domain Operating Condition #####
- ==============================================================================
- [..] As long as the supply voltage remains in the operating range,
- the RTC never stops, regardless of the device status (Run mode,
- low power modes or under reset).
-
- ##### Backup Domain Reset #####
- ==================================================================
- [..] The backup domain reset sets all RTC registers and the RCC_CSR register
- to their reset values.
- [..] A backup domain reset is generated when one of the following events occurs:
- (+) Software reset, triggered by setting the RTCRST bit in the
- RCC Control Status register (RCC_CSR).
- (+) Power reset (BOR/POR/PDR).
-
- ##### Backup Domain Access #####
- ==================================================================
- [..] After reset, the backup domain (RTC registers and RTC backup data registers)
- is protected against possible unwanted write accesses.
- [..] To enable access to the RTC Domain and RTC registers, proceed as follows:
- (+) Enable the Power Controller (PWR) APB1 interface clock using the
- __PWR_CLK_ENABLE() function.
- (+) Enable access to RTC domain using the HAL_PWR_EnableBkUpAccess() function.
- (+) Select the RTC clock source using the __HAL_RCC_RTC_CONFIG() function.
- (+) Enable RTC Clock using the __HAL_RCC_RTC_ENABLE() function.
-
-
- ##### How to use this driver #####
- ==================================================================
- [..]
- (+) Enable the RTC domain access (see description in the section above).
- (+) Configure the RTC Prescaler (Asynchronous and Synchronous) and RTC hour
- format using the HAL_RTC_Init() function.
-
- *** Time and Date configuration ***
- ===================================
- [..]
- (+) To configure the RTC Calendar (Time and Date) use the HAL_RTC_SetTime()
- and HAL_RTC_SetDate() functions.
- (+) To read the RTC Calendar, use the HAL_RTC_GetTime() and HAL_RTC_GetDate() functions.
-
- *** Alarm configuration ***
- ===========================
- [..]
- (+) To configure the RTC Alarm use the HAL_RTC_SetAlarm() function.
- You can also configure the RTC Alarm with interrupt mode using the HAL_RTC_SetAlarm_IT() function.
- (+) To read the RTC Alarm, use the HAL_RTC_GetAlarm() function.
-
- *** RTC Wakeup configuration ***
- ================================
- [..]
- (+) To configure the RTC Wakeup Clock source and Counter use the HAL_RTC_SetWakeUpTimer()
- function. You can also configure the RTC Wakeup timer with interrupt mode
- using the HAL_RTC_SetWakeUpTimer_IT() function.
- (+) To read the RTC WakeUp Counter register, use the HAL_RTC_GetWakeUpTimer()
- function.
-
- *** Outputs configuration ***
- =============================
- [..] The RTC has 2 different outputs:
- (+) RTC_ALARM: this output is used to manage the RTC Alarm A, Alarm B
- and WaKeUp signals.
- To output the selected RTC signal, use the HAL_RTC_Init() function.
- (+) RTC_CALIB: this output is 512Hz signal or 1Hz.
- To enable the RTC_CALIB, use the HAL_RTCEx_SetCalibrationOutPut() function.
- (+) Two pins can be used as RTC_ALARM or RTC_CALIB (PC13, PB14) managed on
- the RTC_OR register.
- (+) When the RTC_CALIB or RTC_ALARM output is selected, the RTC_OUT pin is
- automatically configured in output alternate function.
-
- *** Smooth digital Calibration configuration ***
- ================================================
- [..]
- (+) Configure the RTC Original Digital Calibration Value and the corresponding
- calibration cycle period (32s,16s and 8s) using the HAL_RTCEx_SetSmoothCalib()
- function.
-
- *** TimeStamp configuration ***
- ===============================
- [..]
- (+) Enables the RTC TimeStamp using the HAL_RTC_SetTimeStamp() function.
- You can also configure the RTC TimeStamp with interrupt mode using the
- HAL_RTC_SetTimeStamp_IT() function.
- (+) To read the RTC TimeStamp Time and Date register, use the HAL_RTC_GetTimeStamp()
- function.
-
- *** Tamper configuration ***
- ============================
- [..]
- (+) Enable the RTC Tamper and Configure the Tamper filter count, trigger Edge
- or Level according to the Tamper filter (if equal to 0 Edge else Level)
- value, sampling frequency, NoErase, MaskFlag, precharge or discharge and
- Pull-UP using the HAL_RTC_SetTamper() function. You can configure RTC Tamper
- with interrupt mode using HAL_RTC_SetTamper_IT() function.
- (+) The default configuration of the Tamper erases the backup registers. To avoid
- erase, enable the NoErase field on the RTC_TAMPCR register.
-
- *** Backup Data Registers configuration ***
- ===========================================
- [..]
- (+) To write to the RTC Backup Data registers, use the HAL_RTC_BKUPWrite()
- function.
- (+) To read the RTC Backup Data registers, use the HAL_RTC_BKUPRead()
- function.
- (+) The backup registers are reset when a tamper detection event occurs
-
-
- ##### RTC and low power modes #####
- ==================================================================
- [..] The MCU can be woken up from a low power mode by an RTC alternate
- function.
- [..] The RTC alternate functions are the RTC alarms (Alarm A and Alarm B),
- RTC wakeup, RTC tamper event detection and RTC time stamp event detection.
- These RTC alternate functions can wake up the system from the Stop and
- Standby low power modes.
- [..] The system can also wake up from low power modes without depending
- on an external interrupt (Auto-wakeup mode), by using the RTC alarm
- or the RTC wakeup events.
- [..] The RTC provides a programmable time base for waking up from the
- Stop or Standby mode at regular intervals.
- Wakeup from STOP and Standby modes is possible only when the RTC clock source
- is LSE or LSI.

- ===============================================================================
- ##### Initialization and de-initialization functions #####
- ===============================================================================
- [..] This section provides functions allowing to initialize and configure the
- RTC Prescaler (Synchronous and Asynchronous), RTC Hour format, disable
- RTC registers Write protection, enter and exit the RTC initialization mode,
- RTC registers synchronization check and reference clock detection enable.
- (#) The RTC Prescaler is programmed to generate the RTC 1Hz time base.
- It is split into 2 programmable prescalers to minimize power consumption.
- (++) A 7-bit asynchronous prescaler and a 13-bit synchronous prescaler.
- (++) When both prescalers are used, it is recommended to configure the
- asynchronous prescaler to a high value to minimize power consumption.
- (#) All RTC registers are Write protected. Writing to the RTC registers
- is enabled by writing a key into the Write Protection register, RTC_WPR.
- (#) To configure the RTC Calendar, user application should enter
- initialization mode. In this mode, the calendar counter is stopped
- and its value can be updated. When the initialization sequence is
- complete, the calendar restarts counting after 4 RTCCLK cycles.
- (#) To read the calendar through the shadow registers after Calendar
- initialization, calendar update or after wakeup from low power modes
- the software must first clear the RSF flag. The software must then
- wait until it is set again before reading the calendar, which means
- that the calendar registers have been correctly copied into the
- RTC_TR and RTC_DR shadow registers.The HAL_RTC_WaitForSynchro() function
- implements the above software sequence (RSF clear and RSF check).

- * @brief Extended RTC HAL module driver.
- *
- * This file provides firmware functions to manage the following
- * functionalities of the Real Time Clock (RTC) Extension peripheral:
- * + RTC Time Stamp functions
- * + RTC Tamper functions
- * + RTC Wake-up functions
- * + Extension Control functions
- * + Extension RTC features functions
- *
- @verbatim
- ==============================================================================
- ##### Backup Domain Operating Condition #####
- ==============================================================================
- [..] As long as the supply voltage remains in the operating range,
- the RTC never stops, regardless of the device status (Run mode,
- low power modes or under reset).
-
- ##### Backup Domain Reset #####
- ==================================================================
- [..] The backup domain reset sets all RTC registers and the RCC_CSR register
- to their reset values.
- [..] A backup domain reset is generated when one of the following events occurs:
- (+) Software reset, triggered by setting the RTCRST bit in the
- RCC Control Status register (RCC_CSR).
- (+) Power reset (BOR/POR/PDR).
-
- ##### Backup Domain Access #####
- ==================================================================
- [..] After reset, the backup domain (RTC registers and RTC backup data registers)
- is protected against possible unwanted write accesses.
- [..] To enable access to the RTC Domain and RTC registers, proceed as follows:
- (+) Enable the Power Controller (PWR) APB1 interface clock using the
- __PWR_CLK_ENABLE() function.
- (+) Enable access to RTC domain using the HAL_PWR_EnableBkUpAccess() function.
- (+) Select the RTC clock source using the __HAL_RCC_RTC_CONFIG() function.
- (+) Enable RTC Clock using the __HAL_RCC_RTC_ENABLE() function.
-
-
- ##### How to use this driver #####
- ==============================================================================
- [..]
- (+) Enable the RTC domain access.
- (+) Configure the RTC Prescaler (Asynchronous and Synchronous) and RTC hour
- format using the HAL_RTC_Init() function.
-
- *** Time and Date configuration ***
- ===================================
- [..]
- (+) To configure the RTC Calendar (Time and Date) use the HAL_RTC_SetTime()
- and HAL_RTC_SetDate() functions.
- (+) To read the RTC Calendar, use the HAL_RTC_GetTime() and HAL_RTC_GetDate() functions.
-
- *** Alarm configuration ***
- ===========================
- [..]
- (+) To configure the RTC Alarm use the HAL_RTC_SetAlarm() function.
- You can also configure the RTC Alarm with interrupt mode using the HAL_RTC_SetAlarm_IT() function.
- (+) To read the RTC Alarm, use the HAL_RTC_GetAlarm() function.
-
- *** RTC Wakeup configuration ***
- ================================
- [..]
- (+) To configure the RTC Wakeup Clock source and Counter use the HAL_RTC_SetWakeUpTimer()
- function. You can also configure the RTC Wakeup timer in interrupt mode
- using the HAL_RTC_SetWakeUpTimer_IT() function.
- (+) To read the RTC WakeUp Counter register, use the HAL_RTC_GetWakeUpTimer()
- function.
-
- *** Outputs configuration ***
- =============================
- [..] The RTC has 2 different outputs:
- (+) RTC_ALARM: this output is used to manage the RTC Alarm A, Alarm B
- and WaKeUp signals.
- To output the selected RTC signal, use the HAL_RTC_Init() function.
- (+) RTC_CALIB: this output is 512Hz signal or 1Hz.
- To enable the RTC_CALIB, use the HAL_RTCEx_SetCalibrationOutPut() function.
- (+) Two pins can be used as RTC_ALARM or RTC_CALIB (PC13, PB14) managed on
- the RTC_OR register.
- (+) When the RTC_CALIB or RTC_ALARM output is selected, the RTC_OUT pin is
- automatically configured in output alternate function.
-
- *** Smooth digital Calibration configuration ***
- ================================================
- [..]
- (+) Configure the RTC Original Digital Calibration Value and the corresponding
- calibration cycle period (32s,16s and 8s) using the HAL_RTCEx_SetSmoothCalib()
- function.
-
- *** TimeStamp configuration ***
- ===============================
- [..]
- (+) Enables the RTC TimeStamp using the HAL_RTC_SetTimeStamp() function.
- You can also configure the RTC TimeStamp with interrupt mode using the
- HAL_RTC_SetTimeStamp_IT() function.
- (+) To read the RTC TimeStamp Time and Date register, use the HAL_RTC_GetTimeStamp()
- function.
-
- *** Tamper configuration ***
- ============================
- [..]
- (+) Enable the RTC Tamper and Configure the Tamper filter count, trigger Edge
- or Level according to the Tamper filter (if equal to 0 Edge else Level)
- value, sampling frequency, NoErase, MaskFlag, precharge or discharge and
- Pull-UP using the HAL_RTC_SetTamper() function. You can configure RTC Tamper
- with interrupt mode using HAL_RTC_SetTamper_IT() function.
- (+) The default configuration of the Tamper erases the backup registers. To avoid
- erase, enable the NoErase field on the RTC_TAMPCR register.
-
- *** Backup Data Registers configuration ***
- ===========================================
- [..]
- (+) To write to the RTC Backup Data registers, use the HAL_RTC_BKUPWrite()
- function.
- (+) To read the RTC Backup Data registers, use the HAL_RTC_BKUPRead()
- function.
- (+) The backup registers are reset when a tamper detection event occurs
-
-
- ##### RTC and low power modes #####
- ==================================================================
- [..] The MCU can be woken up from a low power mode by an RTC alternate
- function.
- [..] The RTC alternate functions are the RTC alarms (Alarm A and Alarm B),
- RTC wakeup, RTC tamper event detection and RTC time stamp event detection.
- These RTC alternate functions can wake up the system from the Stop and
- Standby low power modes.
- [..] The system can also wake up from low power modes without depending
- on an external interrupt (Auto-wakeup mode), by using the RTC alarm
- or the RTC wakeup events.
- [..] The RTC provides a programmable time base for waking up from the
- Stop or Standby mode at regular intervals.
- Wakeup from STOP and Standby modes is possible only when the RTC clock source
- is LSE or LSI.

- ===============================================================================
- ##### How to use this driver #####
- ===============================================================================
- [..]
- The SMARTCARD HAL driver can be used as follow:
-
- (#) Declare a SMARTCARD_HandleTypeDef handle structure.
- (#) Associate a USART to the SMARTCARD handle hsc.
- (#) Initialize the SMARTCARD low level resources by implementing the HAL_SMARTCARD_MspInit ()API:
- (##) Enable the USARTx interface clock.
- (##) USART pins configuration:
- (+) Enable the clock for the USART GPIOs.
- (+) Configure these USART pins as alternate function pull-up.
- (##) NVIC configuration if you need to use interrupt process (HAL_SMARTCARD_Transmit_IT()
- and HAL_SMARTCARD_Receive_IT() APIs):
- (+) Configure the USARTx interrupt priority.
- (+) Enable the NVIC USART IRQ handle.
- (@) The specific USART interrupts (Transmission complete interrupt,
- RXNE interrupt and Error Interrupts) will be managed using the macros
- __HAL_SMARTCARD_ENABLE_IT() and __HAL_SMARTCARD_DISABLE_IT() inside the transmit and receive process.
- (##) DMA Configuration if you need to use DMA process (HAL_SMARTCARD_Transmit_DMA()
- and HAL_SMARTCARD_Receive_DMA() APIs):
- (+) Declare a DMA handle structure for the Tx/Rx stream.
- (+) Enable the DMAx interface clock.
- (+) Configure the declared DMA handle structure with the required Tx/Rx parameters.
- (+) Configure the DMA Tx/Rx Stream.
- (+) Associate the initialized DMA handle to the SMARTCARD DMA Tx/Rx handle.
- (+) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx Stream.
-
- (#) Program the Baud Rate, Parity, Mode(Receiver/Transmitter), clock enabling/disabling and accordingly,
- the clock parameters (parity, phase, last bit), prescaler value, guard time and NACK on transmission
- error enabling or disabling in the hsc Init structure.
-
- (#) If required, program SMARTCARD advanced features (TX/RX pins swap, TimeOut, auto-retry counter,...)
- in the hsc AdvancedInit structure.
-
- (#) Initialize the SMARTCARD associated USART registers by calling
- the HAL_SMARTCARD_Init() API.
-
- (@) HAL_SMARTCARD_Init() API also configure also the low level Hardware GPIO, CLOCK, CORTEX...etc) by
- calling the customized HAL_SMARTCARD_MspInit() API.

- ##### IO operation functions #####
- ===============================================================================
- This subsection provides a set of functions allowing to manage the SMARTCARD data transfers.
-
- (#) There are two mode of transfer:
- (+) Blocking mode: The communication is performed in polling mode.
- The HAL status of all data processing is returned by the same function
- after finishing transfer.
- (+) No-Blocking mode: The communication is performed using Interrupts
- or DMA, These API's return the HAL status.
- The end of the data processing will be indicated through the
- dedicated SMARTCARD IRQ when using Interrupt mode or the DMA IRQ when
- using DMA mode.
- The HAL_SMARTCARD_TxCpltCallback(), HAL_SMARTCARD_RxCpltCallback() user callbacks
- will be executed respectivelly at the end of the transmit or Receive process
- The HAL_SMARTCARD_ErrorCallback()user callback will be executed when a communication error is detected
-
- (#) Blocking mode API's are :
- (+) HAL_SMARTCARD_Transmit()
- (+) HAL_SMARTCARD_Receive()
-
- (#) Non-Blocking mode API's with Interrupt are :
- (+) HAL_SMARTCARD_Transmit_IT()
- (+) HAL_SMARTCARD_Receive_IT()
- (+) HAL_SMARTCARD_IRQHandler()
- (+) SMARTCARD_Transmit_IT()
- (+) SMARTCARD_Receive_IT()
-
- (#) No-Blocking mode functions with DMA are :
- (+) HAL_SMARTCARD_Transmit_DMA()

- * @brief SMBUS HAL module driver.
- *
- * This file provides firmware functions to manage the following
- * functionalities of the System Management Bus (SMBus) peripheral,
- * based on I2C principales of operation :
- * + Initialization/de-initialization functions
- * + I/O operation functions
- * + Peripheral Control functions
- * + Peripheral State functions

- @verbatim
- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..]
- The SMBUS HAL driver can be used as follows:
-
- (#) Declare a SMBUS_HandleTypeDef handle structure, for example:
- SMBUS_HandleTypeDef hsmbus;
-
- (#)Initialize the SMBUS low level resources by implement the HAL_SMBUS_MspInit ()API:
- (##) Enable the SMBUSx interface clock
- (##) SMBUS pins configuration
- (+) Enable the clock for the SMBUS GPIOs
- (+) Configure SMBUS pins as alternate function open-drain
- (##) NVIC configuration if you need to use interrupt process
- (+) Configure the SMBUSx interrupt priority
- (+) Enable the NVIC SMBUS IRQ Channel
-
- (#) Configure the Communication Clock Timing, Bus Timeout, Own Address1, Master Adressing Mode,
- Dual Addressing mode, Own Address2, Own Address2 Mask, General call, Nostretch mode,
- Peripheral mode and Packet Error Check mode in the hsmbus Init structure.
-
- (#) Initialize the SMBUS registers by calling the HAL_SMBUS_Init() API:
- (+) These API's configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
- by calling the customed HAL_SMBUS_MspInit(&hsmbus) API.
-
- (#) To check if target device is ready for communication, use the function HAL_SMBUS_IsDeviceReady()
-
- (#) For SMBUS IO operations, only one mode of operations is available within this driver :
-
- *** Interrupt mode IO operation ***
- ===================================
- [..]
- (+) Transmit in master/host SMBUS mode an amount of data in non blocking mode using HAL_SMBUS_Master_Transmit_IT()
- (++) At transmission end of transfer HAL_SMBUS_MasterTxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_SMBUS_MasterTxCpltCallback
- (+) Receive in master/host SMBUS mode an amount of data in non blocking mode using HAL_SMBUS_Master_Receive_IT()
- (++) At reception end of transfer HAL_SMBUS_MasterRxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_SMBUS_MasterRxCpltCallback
- (+) Abort a master/host SMBUS process commnunication with Interrupt using HAL_SMBUS_Master_Abort_IT()
- (++) The associated previous transfer callback is called at the end of abort process
- (++) mean HAL_SMBUS_MasterTxCpltCallback in case of previous state was master transmit
- (++) mean HAL_SMBUS_MasterRxCpltCallback in case of previous state was master receive
- (+) Enable the Address listen mode in slave/device SMBUS mode using HAL_SMBUS_Slave_Listen_IT()
- (++) When address slave/device SMBUS match, HAL_SMBUS_SlaveAddrCallback is executed and user can
- add his own code to check the Address Match Code and the transmission direction request by master/host (Write/Read).
- (++) At Listen mode end HAL_SMBUS_SlaveListenCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_SMBUS_SlaveListenCpltCallback
- (+) Transmit in slave/device SMBUS mode an amount of data in non blocking mode using HAL_SMBUS_Slave_Transmit_IT()
- (++) At transmission end of transfer HAL_SMBUS_SlaveTxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_SMBUS_SlaveTxCpltCallback
- (+) Receive in slave/device SMBUS mode an amount of data in non blocking mode using HAL_SMBUS_Slave_Receive_IT()
- (++) At reception end of transfer HAL_SMBUS_SlaveRxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_SMBUS_SlaveRxCpltCallback
- (+) Enable/Disable the SMBUS alert mode using HAL_SMBUS_EnableAlert_IT() HAL_SMBUS_DisableAlert_IT()
- (++) When SMBUS Alert is generated HAL_SMBUS_ErrorCallback() is executed and user can
- add his own code by customization of function pointer HAL_SMBUS_ErrorCallback
- to check the Alert Error Code using function HAL_SMBUS_GetError()
- (+) Get HAL state machine or error values using HAL_SMBUS_GetState() or HAL_SMBUS_GetError()
- (+) In case of transfer Error, HAL_SMBUS_ErrorCallback() function is executed and user can
- add his own code by customization of function pointer HAL_SMBUS_ErrorCallback
- to check the Error Code using function HAL_SMBUS_GetError()
-
- *** SMBUS HAL driver macros list ***
- ==================================
- [..]
- Below the list of most used macros in SMBUS HAL driver.
-
- (+) __HAL_SMBUS_ENABLE: Enable the SMBUS peripheral
- (+) __HAL_SMBUS_DISABLE: Disable the SMBUS peripheral
- (+) __HAL_SMBUS_GET_FLAG : Checks whether the specified SMBUS flag is set or not
- (+) __HAL_SMBUS_CLEAR_FLAG : Clears the specified SMBUS pending flag
- (+) __HAL_SMBUS_ENABLE_IT: Enables the specified SMBUS interrupt
- (+) __HAL_SMBUS_DISABLE_IT: Disables the specified SMBUS interrupt

- * @author MCD Application Team
- * @version V1.1.0
- * @date 18-June-2014
- * @brief SPI HAL module driver.
- *
- * This file provides firmware functions to manage the following
- * functionalities of the Serial Peripheral Interface (SPI) peripheral:
- * + Initialization and de-initialization functions
- * + IO operation functions
- * + Peripheral Control functions
- * + Peripheral State functions
- @verbatim
- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..]
- The SPI HAL driver can be used as follows:
-
- (#) Declare a SPI_HandleTypeDef handle structure, for example:
- SPI_HandleTypeDef hspi;
-
- (#)Initialize the SPI low level resources by implement the HAL_SPI_MspInit ()API:
- (##) Enable the SPIx interface clock
- (##) SPI pins configuration
- (+++) Enable the clock for the SPI GPIOs
- (+++) Configure these SPI pins as alternate function push-pull
- (##) NVIC configuration if you need to use interrupt process
- (+++) Configure the SPIx interrupt priority
- (+++) Enable the NVIC SPI IRQ handle
- (##) DMA Configuration if you need to use DMA process
- (+++) Declare a DMA_HandleTypeDef handle structure for the transmit or receive stream
- (+++) Enable the DMAx interface clock using
- (+++) Configure the DMA handle parameters
- (+++) Configure the DMA Tx or Rx Stream
- (+++) Associate the initilalized hdma_tx handle to the hspi DMA Tx or Rx handle
- (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx or Rx Stream
-
- (#) Program the Mode, Direction , Data size, Baudrate Prescaler, NSS
- management, Clock polarity and phase, FirstBit and CRC configuration in the hspi Init structure.
-
- (#) Initialize the SPI registers by calling the HAL_SPI_Init() API:
- (++) This API configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
- by calling the customed HAL_SPI_MspInit(&hspi) API.
- [..]
- Circular mode restriction:
- (#) The DMA circular mode cannot be used when the SPI is configured in these modes:
- (##) Master 2Lines RxOnly
- (##) Master 1Line Rx
- (#) The CRC feature is not managed when the DMA circular mode is enabled
- (#) When the SPI DMA Pause/Stop features are used, we must use the following APIs
- the HAL_SPI_DMAPause()/ HAL_SPI_DMAStop() only under the SPI callbacks
-
- [..]
- Using the HAL it is not possible to reach all supported SPI frequency with the differents SPI Modes,
- the following table resume the max SPI frequency reached with data size 8bits/16bits:
- +-----------------------------------------------------------------------------------------+
- | | | 2Lines Fullduplex | 2Lines RxOnly | 1Line |
- | Process | Tranfert mode |--------------------|--------------------|--------------------|
- | | | Master | Slave | Master | Slave | Master | Slave |

- This subsection provides a set of functions allowing to manage the SPI
- data transfers.
-
- [..] The SPI supports master and slave mode :
-
- (#) There are two mode of transfer:
- (++) Blocking mode: The communication is performed in polling mode.
- The HAL status of all data processing is returned by the same function
- after finishing transfer.
- (++) No-Blocking mode: The communication is performed using Interrupts
- or DMA, These API's return the HAL status.
- The end of the data processing will be indicated through the
- dedicated SPI IRQ when using Interrupt mode or the DMA IRQ when
- using DMA mode.
- The HAL_SPI_TxCpltCallback(), HAL_SPI_RxCpltCallback() and HAL_SPI_TxRxCpltCallback() user callbacks
- will be executed respectivelly at the end of the transmit or Receive process
- The HAL_SPI_ErrorCallback()user callback will be executed when a communication error is detected
-
- (#) Blocking mode API's are :
- (++) HAL_SPI_Transmit()in 1Line (simplex) and 2Lines (full duplex) mode
- (++) HAL_SPI_Receive() in 1Line (simplex) and 2Lines (full duplex) mode
- (++) HAL_SPI_TransmitReceive() in full duplex mode
-
- (#) Non-Blocking mode API's with Interrupt are :
- (++) HAL_SPI_Transmit_IT()in 1Line (simplex) and 2Lines (full duplex) mode
- (++) HAL_SPI_Receive_IT() in 1Line (simplex) and 2Lines (full duplex) mode
- (++) HAL_SPI_TransmitReceive_IT()in full duplex mode
- (++) HAL_SPI_IRQHandler()
-
- (#) No-Blocking mode functions with DMA are :
- (++) HAL_SPI_Transmit_DMA()in 1Line (simplex) and 2Lines (full duplex) mode
- (++) HAL_SPI_Receive_DMA() in 1Line (simplex) and 2Lines (full duplex) mode
- (++) HAL_SPI_TransmitReceie_DMA() in full duplex mode

- ==============================================================================
- ##### TIMER Generic features #####
- ==============================================================================
- [..] The Timer features include:
- (#) 16-bit up, down, up/down auto-reload counter.
- (#) 16-bit programmable prescaler allowing dividing (also on the fly) the counter clock
- frequency either by any factor between 1 and 65536.
- (#) Up to 4 independent channels for:
- (++) Input Capture
- (++) Output Compare
- (++) PWM generation (Edge and Center-aligned Mode)
- (++) One-pulse mode output
- (#) Synchronization circuit to control the timer with external signals and to interconnect
- several timers together.
- (#) Supports incremental (quadrature) encoder and hall-sensor circuitry for positioning
- purposes
-
- ##### How to use this driver #####
-================================================================================
- [..]
- (#) Enable the TIM interface clock using
- __TIMx_CLK_ENABLE();
-
- (#) TIM pins configuration
- (++) Enable the clock for the TIM GPIOs using the following function:
- __GPIOx_CLK_ENABLE();
- (++) Configure these TIM pins in Alternate function mode using HAL_GPIO_Init();
-
- (#) The external Clock can be configured, if needed (the default clock is the internal clock from the APBx),
- using the following function:
- HAL_TIM_ConfigClockSource, the clock configuration should be done before any start function.
-
- (#) Configure the TIM in the desired functioning mode using one of the
- initialization function of this driver:
- (++) HAL_TIM_Base_Init: to use the Timer to generate a simple time base
- (++) HAL_TIM_OC_Init and HAL_TIM_OC_ConfigChannel: to use the Timer to generate an
- Output Compare signal.
- (++) HAL_TIM_PWM_Init and HAL_TIM_PWM_ConfigChannel: to use the Timer to generate a
- PWM signal.
- (++) HAL_TIM_IC_Init and HAL_TIM_IC_ConfigChannel: to use the Timer to measure an

- * @brief This file provides firmware functions to manage the following
- * functionalities of the Timer (TIM) peripheral:
- * + Time Hall Sensor Interface Initialization
- * + Time Hall Sensor Interface Start
- * + Time Master and Slave synchronization configuration
- @verbatim
-================================================================================
- ##### TIM specific features integration #####
-================================================================================
-
- [..] The Timer features include:
- (#) 16-bit up, down, up/down auto-reload counter.
- (#) 16-bit programmable prescaler allowing dividing (also on the fly) the counter clock
- frequency either by any factor between 1 and 65536.
- (#) Up to 4 independent channels for:
- Input Capture
- Output Compare
- PWM generation (Edge and Center-aligned Mode)
- One-pulse mode output
- (#) Synchronization circuit to control the timer with external signals and to interconnect
- several timers together.
- (#) Supports incremental (quadrature) encoder and hall-sensor circuitry for positioning
- purposes
-
- ##### How to use this driver #####
-================================================================================
- [..]
- (#) Enable the TIM interface clock using
- __TIMx_CLK_ENABLE();
-
- (#) TIM pins configuration
- (++) Enable the clock for the TIM GPIOs using the following function:
- __GPIOx_CLK_ENABLE();
- (++) Configure these TIM pins in Alternate function mode using HAL_GPIO_Init();
-
- (#) The external Clock can be configured, if needed (the default clock is the internal clock from the APBx),
- using the following function:
- HAL_TIM_ConfigClockSource, the clock configuration should be done before any start function.
-
- (#) Configure the TIM in the desired operating mode using one of the
- configuration function of this driver:
- (++) HAL_TIMEx_MasterConfigSynchronization() to configure the peripheral in master mode.
-
- (#) Remap the Timer I/O using HAL_TIMEx_RemapConfig() API.

- * @brief This file provides firmware functions to manage the following
- * functionalities of the Touch Sensing Controller (TSC) peripheral:
- * + Initialization and DeInitialization
- * + Channel IOs, Shield IOs and Sampling IOs configuration
- * + Start and Stop an acquisition
- * + Read acquisition result

- @verbatim
-================================================================================
- ##### TSC specific features #####
-================================================================================
- [..]
- (#) Proven and robust surface charge transfer acquisition principle
-
- (#) Supports up to 3 capacitive sensing channels per group
-
- (#) Capacitive sensing channels can be acquired in parallel offering a very good
- response time
-
- (#) Spread spectrum feature to improve system robustness in noisy environments
-
- (#) Full hardware management of the charge transfer acquisition sequence
-
- (#) Programmable charge transfer frequency
-
- (#) Programmable sampling capacitor I/O pin
-
- (#) Programmable channel I/O pin
-
- (#) Programmable max count value to avoid long acquisition when a channel is faulty
-
- (#) Dedicated end of acquisition and max count error flags with interrupt capability
-
- (#) One sampling capacitor for up to 3 capacitive sensing channels to reduce the system
- components
-
- (#) Compatible with proximity, touchkey, linear and rotary touch sensor implementation
-
-
- ##### How to use this driver #####
-================================================================================
- [..]
- (#) Enable the TSC interface clock using __TSC_CLK_ENABLE() macro.
-
- (#) GPIO pins configuration
- (++) Enable the clock for the TSC GPIOs using __GPIOx_CLK_ENABLE() macro.
- (++) Configure the TSC pins used as sampling IOs in alternate function output Open-Drain mode,
- and TSC pins used as channel/shield IOs in alternate function output Push-Pull mode
- using HAL_GPIO_Init() function.
- (++) Configure the alternate function on all the TSC pins using HAL_xxxx() function.
-
- (#) Interrupts configuration
- (++) Configure the NVIC (if the interrupt model is used) using HAL_xxx() function.
-
- (#) TSC configuration
- (++) Configure all TSC parameters and used TSC IOs using HAL_TSC_Init() function.
-
- *** Acquisition sequence ***
- ===================================
- [..]
- (+) Discharge all IOs using HAL_TSC_IODischarge() function.
- (+) Wait a certain time allowing a good discharge of all capacitors. This delay depends
- of the sampling capacitor and electrodes design.
- (+) Select the channel IOs to be acquired using HAL_TSC_IOConfig() function.
- (+) Launch the acquisition using either HAL_TSC_Start() or HAL_TSC_Start_IT() function.
- If the synchronized mode is selected, the acquisition will start as soon as the signal
- is received on the synchro pin.
- (+) Wait the end of acquisition using either HAL_TSC_PollForAcquisition() or
- HAL_TSC_GetState() function or using WFI instruction for example.
- (+) Check the group acquisition status using HAL_TSC_GroupGetStatus() function.
- (+) Read the acquisition value using HAL_TSC_GroupGetValue() function.

- * @brief UART HAL module driver.
- *
- * This file provides firmware functions to manage the following
- * functionalities of the Universal Asynchronous Receiver Transmitter Peripheral (UART).
- * + Initialization and de-initialization methods
- * + IO operation methods
- * + Peripheral Control methods
- *
- @verbatim
- ===============================================================================
- ##### How to use this driver #####
- ===============================================================================
- [..]
- The UART HAL driver can be used as follows:
-
- (#) Declare a UART_HandleTypeDef handle structure.
-
- (#) Initialize the UART low level resources by implementing the HAL_UART_MspInit() API:
- (##) Enable the USARTx interface clock.
- (##) UART pins configuration:
- (+++) Enable the clock for the UART GPIOs.
- (+++) Configure these UART pins as alternate function pull-up.
- (##) NVIC configuration if you need to use interrupt process (HAL_UART_Transmit_IT()
- and HAL_UART_Receive_IT() APIs):
- (+++) Configure the USARTx interrupt priority.
- (+++) Enable the NVIC USART IRQ handle.
-
- (##) DMA Configuration if you need to use DMA process (HAL_UART_Transmit_DMA()
- and HAL_UART_Receive_DMA() APIs):
- (+++) Declare a DMA handle structure for the Tx/Rx stream.
- (+++) Enable the DMAx interface clock.
- (+++) Configure the declared DMA handle structure with the required
- Tx/Rx parameters.
- (+++) Configure the DMA Tx/Rx Stream.
- (+++) Associate the initialized DMA handle to the UART DMA Tx/Rx handle.
- (+++) Configure the priority and enable the NVIC for the transfer complete
- interrupt on the DMA Tx/Rx Stream.
-
- (#) Program the Baud Rate, Word Length, Stop Bit, Parity, Hardware
- flow control and Mode(Receiver/Transmitter) in the Init structure.
-
- (#) For the UART asynchronous mode, initialize the UART registers by calling
- the HAL_UART_Init() API.
-
- (#) For the UART Half duplex mode, initialize the UART registers by calling
- the HAL_HalfDuplex_Init() API.
-
- (#) For the LIN mode, initialize the UART registers by calling the HAL_LIN_Init() API.
-
- (#) For the Multi-Processor mode, initialize the UART registers by calling
- the HAL_MultiProcessor_Init() API.
-
- [..]
- (@) The specific UART interrupts (Transmission complete interrupt,
- RXNE interrupt and Error Interrupts) will be managed using the macros
- __HAL_UART_ENABLE_IT() and __HAL_UART_DISABLE_IT() inside the transmit
- and receive process.
-
- [..]
- (@) These APIs (HAL_UART_Init() and HAL_HalfDuplex_Init()) configure also the
- low level Hardware GPIO, CLOCK, CORTEX...etc) by calling the customed
- HAL_UART_MspInit() API.
-
- [..]
- Three operation modes are available within this driver :
-
- *** Polling mode IO operation ***
- =================================

- ##### Initialization and Configuration functions #####
- ===============================================================================
- [..]
- This subsection provides a set of functions allowing to initialize the USARTx or the UARTy
- in asynchronous mode.
- (+) For the asynchronous mode only these parameters can be configured:
- (++) Baud Rate
- (++) Word Length
- (++) Stop Bit
- (++) Parity: If the parity is enabled, then the MSB bit of the data written
- in the data register is transmitted but is changed by the parity bit.
- Depending on the frame length defined by the M bit (8-bits or 9-bits),
- the possible UART frame formats are as listed in the following table:
- +-----------------------------------------------------------------------+
- | M1 bit | M0 bit | PCE bit | USART frame |
- |---------|---------|-----------|---------------------------------------|
- | 0 | 0 | 0 | | SB | 8 bit data | STB | |
- |---------|---------|-----------|---------------------------------------|
- | 0 | 0 | 1 | | SB | 7 bit data | PB | STB | |
- |---------|---------|-----------|---------------------------------------|
- | 0 | 1 | 0 | | SB | 9 bit data | STB | |
- |---------|---------|-----------|---------------------------------------|
- | 0 | 1 | 1 | | SB | 8 bit data | PB | STB | |
- |---------|---------|-----------|---------------------------------------|
- | 1 | 0 | 0 | | SB | 7 bit data | STB | |
- |---------|---------|-----------|---------------------------------------|
- | 1 | 0 | 1 | | SB | 6 bit data | PB | STB | |
- +-----------------------------------------------------------------------+
- (++) Hardware flow control
- (++) Receiver/transmitter modes
- (++) Over Sampling Method
- (++) One-Bit Sampling Method
- (+) For the asynchronous mode, the following advanced features can be configured as well:
- (++) TX and/or RX pin level inversion
- (++) data logical level inversion
- (++) RX and TX pins swap
- (++) RX overrun detection disabling
- (++) DMA disabling on RX error
- (++) MSB first on communication line
- (++) auto Baud rate detection
- [..]
- The HAL_UART_Init(), HAL_HalfDuplex_Init(), HAL_LIN_Init()and HAL_MultiProcessorEx_Init()API
- follow respectively the UART asynchronous, UART Half duplex, UART LIN mode
- and UART multiprocessor mode mode configuration procedures (details for the procedures
- are available in reference manual).

- (+) Blocking mode: The communication is performed in polling mode.
- The HAL status of all data processing is returned by the same function
- after finishing transfer.
- (+) No-Blocking mode: The communication is performed using Interrupts
- or DMA, These API's return the HAL status.
- The end of the data processing will be indicated through the
- dedicated UART IRQ when using Interrupt mode or the DMA IRQ when
- using DMA mode.
- The HAL_UART_TxCpltCallback(), HAL_UART_RxCpltCallback() user callbacks
- will be executed respectivelly at the end of the transmit or Receive process
- The HAL_UART_ErrorCallback()user callback will be executed when a communication error is detected
-
- (#) Blocking mode API's are :
- (+) HAL_UART_Transmit()
- (+) HAL_UART_Receive()
-
- (#) Non-Blocking mode API's with Interrupt are :
- (+) HAL_UART_Transmit_IT()
- (+) HAL_UART_Receive_IT()
- (+) HAL_UART_IRQHandler()
- (+) UART_Transmit_IT()
- (+) UART_Receive_IT()

- ===============================================================================
- ##### How to use this driver #####
- ===============================================================================
- [..]
- The USART HAL driver can be used as follows:
-
- (#) Declare a USART_HandleTypeDef handle structure.
- (#) Initialize the USART low level resources by implement the HAL_USART_MspInit ()API:
- (##) Enable the USARTx interface clock.
- (##) USART pins configuration:
- (+++) Enable the clock for the USART GPIOs.
- (+++) Configure these USART pins as alternate function pull-up.
- (##) NVIC configuration if you need to use interrupt process (HAL_USART_Transmit_IT(),
- HAL_USART_Receive_IT() and HAL_USART_TransmitReceive_IT() APIs):
- (+++) Configure the USARTx interrupt priority.
- (+++) Enable the NVIC USART IRQ handle.
- (@) The specific USART interrupts (Transmission complete interrupt,
- RXNE interrupt and Error Interrupts) will be managed using the macros
- __HAL_USART_ENABLE_IT() and __HAL_USART_DISABLE_IT() inside the transmit and receive process.
- (##) DMA Configuration if you need to use DMA process (HAL_USART_Transmit_DMA()
- HAL_USART_Receive_IT() and HAL_USART_TransmitReceive_IT() APIs):
- (+++) Declare a DMA handle structure for the Tx/Rx stream.
- (+++) Enable the DMAx interface clock.
- (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.
- (+++) Configure the DMA Tx/Rx Stream.
- (+++) Associate the initilalized DMA handle to the USART DMA Tx/Rx handle.
- (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx Stream.
-
- (#) Program the Baud Rate, Word Length, Stop Bit, Parity, Hardware
- flow control and Mode(Receiver/Transmitter) in the husart Init structure.
-
- (#) Initialize the USART registers by calling the HAL_USART_Init() API:
- (+) These API's configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
- by calling the customed HAL_USART_MspInit(&husart) API.

- [..]
- This subsection provides a set of functions allowing to initialize the USART
- in asynchronous and in synchronous modes.
- (+) For the asynchronous mode only these parameters can be configured:
- (++) Baud Rate
- (++) Word Length
- (++) Stop Bit
- (++) Parity: If the parity is enabled, then the MSB bit of the data written
- in the data register is transmitted but is changed by the parity bit.
- Depending on the frame length defined by the M bit (8-bits or 9-bits),
- the possible USART frame formats are as listed in the following table:
- +-------------------------------------------------------------+
- | M0 bit | PCE bit | USART frame |
- |---------------------|---------------------------------------|
- | 0 | 0 | | SB | 8 bit data | STB | |
- |---------|-----------|---------------------------------------|
- | 0 | 1 | | SB | 7 bit data | PB | STB | |
- |---------|-----------|---------------------------------------|
- | 1 | 0 | | SB | 9 bit data | STB | |
- |---------|-----------|---------------------------------------|
- | 1 | 1 | | SB | 8 bit data | PB | STB | |
- +-------------------------------------------------------------+
- (++) USART polarity
- (++) USART phase
- (++) USART LastBit
- (++) Receiver/transmitter modes
-
- [..]
- The HAL_USART_Init() function follows the USART synchronous configuration
- procedure (details for the procedure are available in reference manual (RM0329)).

- ===============================================================================
- ##### IO operation functions #####
- ===============================================================================
- [..]
- This subsection provides a set of functions allowing to manage the USART synchronous
- data transfers.
-
- [..] The USART supports master mode only: it cannot receive or send data related to an input
- clock (SCLK is always an output).
-
- (#) There are two modes of transfer:
- (++) Blocking mode: The communication is performed in polling mode.
- The HAL status of all data processing is returned by the same function
- after finishing transfer.
- (++) No-Blocking mode: The communication is performed using Interrupts
- or DMA, These API's return the HAL status.
- The end of the data processing will be indicated through the
- dedicated USART IRQ when using Interrupt mode or the DMA IRQ when
- using DMA mode.
- The HAL_USART_TxCpltCallback(), HAL_USART_RxCpltCallback() and HAL_USART_TxRxCpltCallback() user callbacks
- will be executed respectivelly at the end of the transmit or Receive process
- The HAL_USART_ErrorCallback()user callback will be executed when a communication error is detected.
-
- (#) Blocking mode API's are :
- (++) HAL_USART_Transmit()in simplex mode
- (++) HAL_USART_Receive() in full duplex receive only
- (++) HAL_USART_TransmitReceive() in full duplex mode
-
- (#) Non-Blocking mode API's with Interrupt are :
- (++) HAL_USART_Transmit_IT()in simplex mode
- (++) HAL_USART_Receive_IT() in full duplex receive only
- (++) HAL_USART_TransmitReceive_IT()in full duplex mode
- (++) HAL_USART_IRQHandler()
-
- (#) No-Blocking mode functions with DMA are :
- (++) HAL_USART_Transmit_DMA()in simplex mode
- (++) HAL_USART_Receive_DMA() in full duplex receive only
- (++) HAL_USART_TransmitReceive_DMA() in full duplex mode
- (++) HAL_USART_DMAPause()
- (++) HAL_USART_DMAResume()
- (++) HAL_USART_DMAStop()
-
- (#) A set of Transfer Complete Callbacks are provided in No_Blocking mode:
- (++) HAL_USART_TxCpltCallback()
- (++) HAL_USART_RxCpltCallback()
- (++) HAL_USART_TxHalfCpltCallback()
- (++) HAL_USART_RxHalfCpltCallback()
- (++) HAL_USART_ErrorCallback()
- (++) HAL_USART_TxRxCpltCallback()

- * @author MCD Application Team
- * @version V1.1.0
- * @date 18-June-2014
- * @brief WWDG HAL module driver.
- * This file provides firmware functions to manage the following
- * functionalities of the Window Watchdog (WWDG) peripheral:
- * + Initialization and de-initialization functions
- * + IO operation functions
- * + Peripheral State functions
- @verbatim
- ==============================================================================
- ##### WWDG specific features #####
- ==============================================================================
- [..]
- Once enabled the WWDG generates a system reset on expiry of a programmed
- time period, unless the program refreshes the counter (downcounter)
- before reaching 0x3F value (i.e. a reset is generated when the counter
- value rolls over from 0x40 to 0x3F).
-
- (+) An MCU reset is also generated if the counter value is refreshed
- before the counter has reached the refresh window value. This
- implies that the counter must be refreshed in a limited window.
- (+) Once enabled the WWDG cannot be disabled except by a system reset.
- (+) WWDGRST flag in RCC_CSR register can be used to inform when a WWDG
- reset occurs.
- (+) The WWDG counter input clock is derived from the APB clock divided
- by a programmable prescaler.
- (+) WWDG counter clock = PCLK1 / Prescaler
- WWDG timeout = (WWDG counter clock) * (counter value)
- (+) Min-max timeout value @32 MHz(PCLK1): ~128.0 us / ~65.54 ms
-
-
- ##### How to use this driver #####
- ==============================================================================
- [..]
- (+) Enable WWDG APB1 clock using __WWDG_CLK_ENABLE().
- (+) Set the WWDG prescaler, refresh window and counter value
- using HAL_WWDG_Init() function.
- (+) Start the WWDG using HAL_WWDG_Start() function.
- When the WWDG is enabled the counter value should be configured to
- a value greater than 0x40 to prevent generating an immediate reset.
- (+) Optionally you can enable the Early Wakeup Interrupt (EWI) which is
- generated when the counter reaches 0x40, and then start the WWDG using
- HAL_WWDG_Start_IT().
- Once enabled, EWI interrupt cannot be disabled except by a system reset.
- (+) Then the application program must refresh the WWDG counter at regular
- intervals during normal operation to prevent an MCU reset, using
- HAL_WWDG_Refresh() function. This operation must occur only when
- the counter is lower than the refresh window value already programmed.
-
- *** WWDG HAL driver macros list ***
- ==================================
- [..]
- Below the list of most used macros in WWDG HAL driver.
-
- (+) __HAL_WWDG_ENABLE: Enable the WWDG peripheral
- (+) __HAL_WWDG_GET_FLAG: Get the selected WWDG's flag status
- (+) __HAL_WWDG_CLEAR_FLAG: Clear the WWDG's pending flags
- (+) __HAL_WWDG_ENABLE_IT: Enables the WWDG early wakeup interrupt

- * @version V1.1.0
- * @date 18-June-2014
- * @brief CMSIS Cortex-M0+ Device Peripheral Access Layer System Source File.
- *
- * This file provides two functions and one global variable to be called from
- * user application:
- * - SystemInit(): This function is called at startup just after reset and
- * before branch to main program. This call is made inside
- * the "startup_stm32l0xx.s" file.
- *
- * - SystemCoreClock variable: Contains the core clock (HCLK), it can be used
- * by the user application to setup the SysTick
- * timer or configure other parameters.
- *
- * - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must
- * be called whenever the core clock is changed
- * during program execution.
- *
- * This file configures the system clock as follows:
- *-----------------------------------------------------------------------------
- * System clock source | 1- PLL_HSE_EXTC | 3- PLL_HSI
- * | (external 8 MHz clock) | (internal 16 MHz)
- * | 2- PLL_HSE_XTAL |
- * | (external 8 MHz xtal) |
- *-----------------------------------------------------------------------------
- * SYSCLK(MHz) | 32 | 32
- *-----------------------------------------------------------------------------
- * AHBCLK (MHz) | 32 | 32
- *-----------------------------------------------------------------------------
- * APB1CLK (MHz) | 32 | 32
- *-----------------------------------------------------------------------------
- * APB2CLK (MHz) | 32 | 32
- *-----------------------------------------------------------------------------
- * USB capable (48 MHz precise clock) | YES | YES
- *-----------------------------------------------------------------------------

- * @brief CMSIS Cortex-M0+ Device Peripheral Access Layer Header File.
- * This file contains all the peripheral register's definitions, bits
- * definitions and memory mapping for STM32L0xx devices.
- *
- * The file is the unique include file that the application programmer
- * is using in the C source code, usually in main.c. This file contains:
- * - Configuration section that allows to select:
- * - The device used in the target application
- * - To use or not the peripheralâs drivers in application code(i.e.
- * code will be based on direct access to peripheralâs registers
- * rather than drivers API), this option is controlled by
- * "#define USE_HAL_DRIVER"

- [..]
- The common HAL driver contains a set of generic and common APIs that can be
- used by the PPP peripheral drivers and the user to start using the HAL.
- [..]
- The HAL contains two APIs' categories:
- (+) Common HAL APIs
- (+) Services HAL APIs

- ##### Initialization and de-initialization functions #####
- ===============================================================================
- [..] This section provides functions allowing to:
- (+) Initializes the Flash interface, the NVIC allocation and initial clock
- configuration. It initializes the source of time base also when timeout
- is needed and the backup domain when enabled.
- (+) de-Initializes common part of the HAL.
- (+) Configure The time base source to have 1ms time base with a dedicated
- Tick interrupt priority.
- (++) Systick timer is used by default as source of time base, but user
- can eventually implement his proper time base source (a general purpose
- timer for example or other time source), keeping in mind that Time base
- duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and
- handled in milliseconds basis.
- (++) Time base configuration function (HAL_InitTick ()) is called automatically
- at the beginning of the program after reset by HAL_Init() or at any time
- when clock is configured, by HAL_RCC_ClockConfig().
- (++) Source of time base is configured to generate interrupts at regular
- time intervals. Care must be taken if HAL_Delay() is called from a
- peripheral ISR process, the Tick interrupt line must have higher priority
- (numerically lower) than the peripheral interrupt. Otherwise the caller
- ISR process will be blocked.
- (++) functions affecting time base configurations are declared as __Weak
- to make override possible in case of other implementations in user file.

- * functionalities of the Analog to Digital Convertor (ADC)
- * peripheral:
- * + Initialization and de-initialization functions
- * ++ Initialization and Configuration of ADC
- * + Operation functions

- @verbatim
- ==============================================================================
- ##### ADC specific features #####
- ==============================================================================
- [..]
- (#) 12-bit, 10-bit, 8-bit or 6-bit configurable resolution.
-
- (#) A built-in hardware oversampler allows to improve analog performances
- while off-loading the related computational burden from the CPU.
-
- (#) Interrupt generation at the end of conversionand in case of analog
- watchdog or overrun events.
-
- (#) Single and continuous conversion modes.
-
- (#) Scan or dicontinuous mode conversion of channel 0 to channel 18.
-
- (#) Configurable scan direction (Upward from channel 0 to 18 or Backward from
- channel 18 to channel 0)
-
- (#) Data alignment with in-built data coherency.
-
- (#) Channel-wise programmable sampling time.
-
- (#) External trigger option with configurable polarity.
-
- (#) DMA request generation during regular channel conversion.
-
- (#) ADC supply requirements: 2.4 V to 3.6 V at full speed and down to 1.8 V at
- slower speed.
-
- (#) ADC input range: VREF=VIN =VREF+.
-
- (#) ADC self-calibration.
-
- (#) ADC is automatically powered off (AutoOff mode) except during the active
- conversion phase. This dramatically reduces the power consumption of the
- ADC.
-
- (#) Wait mode to prevent ADC overrun in applications with low frequency.
-
-
- ##### How to use this driver #####
- ==============================================================================
- [..]
-
- (#) Enable the ADC interface
- As prerequisite, into HAL_ADC_MspInit(), ADC clock must be configured
- at RCC top level.
-
- Depending on both possible clock sources: PCLK clock or ADC asynchronous
- clock.
- __ADC1_CLK_ENABLE();
-
-
- (#) ADC pins configuration
- (++) Enable the clock for the ADC GPIOs using the following function:
- __GPIOx_CLK_ENABLE();
- (++) Configure these ADC pins in analog mode using HAL_GPIO_Init();
-
- (#) Configure the ADC parameters (conversion resolution, oversampler,
- data alignment, continuous mode,...) using the HAL_ADC_Init() function.
-
- (#) Activate the ADC peripheral using one of the start functions:
- HAL_ADC_Start(), HAL_ADC_Start_IT() or HAL_ADC_Start_DMA()
-
- *** Channels configuration ***
- ===============================
- [..]
- (+) To configure the ADC channels group, use HAL_ADC_ConfigChannel() function.
- (+) To read the ADC converted values, use the HAL_ADC_GetValue() function.
-
- *** DMA feature configuration ***
- =================================
- [..]
- (+) To enable the DMA mode, use the HAL_ADC_Start_DMA() function.
- (+) To enable the generation of DMA requests continuously at the end of
- the last DMA transfer, set .Init.DMAContinuousRequests to ENABLE and
- call HAL_ADC_Init() function.

-================================================================================
-
- [..]
- The STM32L0xx device family integrates 2 analog comparators COMP1 and COMP2:
- (#) The non inverting input and inverting input can be set to GPIO pins
- as shown in table1. COMP Inputs below.
-
- (#) The COMP output is available using HAL_COMP_GetOutputLevel()
- and can be set on GPIO pins. Refer to table 2. COMP Outputs below.
-
- (#) The COMP output can be redirected to embedded timers (TIM2, TIM21, TIM22...) and LPTIM
- Refer to TIM and LPTIM drivers.
-
- (#) The comparators COMP1 and COMP2 can be combined in window mode and only COMP2 non inverting input can be used as non-inverting input.
-
- (#) The 2 comparators have interrupt capability with wake-up
- from Sleep and Stop modes (through the EXTI controller):
- (++) COMP1 is internally connected to EXTI Line 21
- (++) COMP2 is internally connected to EXTI Line 22
-
- From the corresponding IRQ handler, the right interrupt source can be retrieved with the
- macro __HAL_COMP_EXTI_GET_FLAG(). Possible values are:
- (++) COMP_EXTI_LINE_COMP1_EVENT
- (++) COMP_EXTI_LINE_COMP2_EVENT

- ##### How to use this driver #####
-================================================================================
- [..]
- This driver provides functions to configure and program the Comparators of all STM32L0xx devices.
-
- To use the comparator, perform the following steps:
-
- (#) Initialize the COMP low level resources by implementing the HAL_COMP_MspInit().
- (++) Enable the SYSCFG APB clock to get write access to comparator register using __SYSCFG_CLK_ENABLE().
- (++) Configure the comparator input in analog mode using HAL_GPIO_Init().
- (++) Configure the comparator output in alternate function mode using HAL_GPIO_Init() to map the comparator
- output to the GPIO pin.
- (++) If required enable the VREFINT reference using HAL_VREFINT_Cmd() and HAL_COMP_EnableBuffer_Cmd().
- (++) If required enable the COMP interrupt by configuring and enabling EXTI line in Interrupt mode and
- selecting the desired sensitivity level using HAL_GPIO_Init() function. After that enable the comparator
- interrupt vector using HAL_NVIC_EnableIRQ() function.
-
- (#) Configure the comparator using HAL_COMP_Init() function:
- (++) Select the inverting input
- (++) Select the non-inverting input
- (++) Select the output polarity
- (++) Select the power mode
- (++) Select the window mode
-
- (#) Enable the comparator using HAL_COMP_Start() function

- * @brief CORTEX HAL module driver.
- * This file provides firmware functions to manage the following
- * functionalities of the CORTEX:
- * + Initialization and de-initialization functions
- * + Peripheral Control functions
- *
- @verbatim
- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
-
- [..]
- *** How to configure Interrupts using CORTEX HAL driver ***
- ===========================================================
- [..]
- This section provide functions allowing to configure the NVIC interrupts (IRQ).
- The Cortex-M0+ exceptions are managed by CMSIS functions.
- (#) Enable and Configure the priority of the selected IRQ Channels.
- The priority can be 0..3.
-
- -@- Lower priority values gives higher priority.
- -@- Priority Order:
- (#@) Lowest priority.
- (#@) Lowest hardware priority (IRQn position).
-
- (#) Configure the priority of the selected IRQ Channels using HAL_NVIC_SetPriority()
-
- (#) Enable the selected IRQ Channels using HAL_NVIC_EnableIRQ()
-
- [..]
- *** How to configure Systick using CORTEX HAL driver ***
- ========================================================
- [..]
- Setup SysTick Timer for time base
-
- (+) The HAL_SYSTICK_Config()function calls the SysTick_Config() function which
- is a CMSIS function that:
- (++) Configures the SysTick Reload register with value passed as function parameter.
- (++) Configures the SysTick IRQ priority to the lowest value (0x03).
- (++) Resets the SysTick Counter register.
- (++) Configures the SysTick Counter clock source to be Core Clock Source (HCLK).
- (++) Enables the SysTick Interrupt.
- (++) Starts the SysTick Counter.
-
- (+) You can change the SysTick Clock source to be HCLK_Div8 by calling the macro
- __HAL_CORTEX_SYSTICKCLK_CONFIG(SYSTICK_CLKSOURCE_HCLK_DIV8) just after the
- HAL_SYSTICK_Config() function call. The __HAL_CORTEX_SYSTICKCLK_CONFIG() macro is defined
- inside the stm32l0xx_hal_cortex.h file.
-
- (+) You can change the SysTick IRQ priority by calling the
- HAL_NVIC_SetPriority(SysTick_IRQn,...) function just after the HAL_SYSTICK_Config() function
- call. The HAL_NVIC_SetPriority() call the NVIC_SetPriority() function which is a CMSIS function.
-
- (+) To adjust the SysTick time base, use the following formula:
-
- Reload Value = SysTick Counter Clock (Hz) x Desired Time base (s)
- (++) Reload Value is the parameter to be passed for HAL_SYSTICK_Config() function
- (++) Reload Value should not exceed 0xFFFFFF

- * This file provides firmware functions to manage the following

- * + Initialization and de-initialization functions
- * + Processing functions by algorithm using polling mode
- * + Processing functions by algorithm using interrupt mode

- *
- @verbatim
- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..]
- The CRYP HAL driver can be used as follows:
-
- (#)Initialize the CRYP low level resources by implementing the HAL_CRYP_MspInit():
- (##) Enable the CRYP interface clock using __CRYP_CLK_ENABLE()
- (##) In case of using interrupts (e.g. HAL_AES_ECB_Encrypt_IT())
- (+) Configure the CRYP interrupt priority using HAL_NVIC_SetPriority()
- (+) Enable the CRYP IRQ handler using HAL_NVIC_EnableIRQ()
- (+) In CRYP IRQ handler, call HAL_CRYP_IRQHandler()
- (##) In case of using DMA to control data transfer (e.g. HAL_AES_ECB_Encrypt_DMA())
- (+) Enable the DMA1 interface clock using
- (++) __DMA1_CLK_ENABLE()
- (+) Configure and enable two DMA Channels one for managing data transfer from
- memory to peripheral (input channel) and another channel for managing data
- transfer from peripheral to memory (output channel)
- (+) Associate the initilalized DMA handle to the CRYP DMA handle
- using __HAL_LINKDMA()
- (+) Configure the priority and enable the NVIC for the transfer complete
- interrupt on the two DMA Streams. The output stream should have higher
- priority than the input stream.
- (++) HAL_NVIC_SetPriority()
- (++) HAL_NVIC_EnableIRQ()
-
- (#)Initialize the CRYP HAL using HAL_CRYP_Init(). This function configures mainly:
- (##) The data type: 1-bit, 8-bit, 16-bit and 32-bit
- (##) The encryption/decryption key.
- (##) The initialization vector (counter). It is not used ECB mode.
-
- (#)Three processing (encryption/decryption) functions are available:
- (##) Polling mode: encryption and decryption APIs are blocking functions
- i.e. they process the data and wait till the processing is finished
- e.g. HAL_CRYP_AESCBC_Encrypt()
- (##) Interrupt mode: encryption and decryption APIs are not blocking functions
- i.e. they process the data under interrupt
- e.g. HAL_CRYP_AESCBC_Encrypt_IT()
- (##) DMA mode: encryption and decryption APIs are not blocking functions
- i.e. the data transfer is ensured by DMA
- e.g. HAL_CRYP_AESCBC_Encrypt_DMA()
-
- (#)When the processing function is called at first time after HAL_CRYP_Init()
- the CRYP peripheral is initialized and processes the buffer in input.
- At second call, the processing function performs an append of the already
- processed buffer.
- When a new data block is to be processed, call HAL_CRYP_Init() then the
- processing function.
-
- (#)Call HAL_CRYP_DeInit() to deinitialize the CRYP peripheral.

- * @brief DAC HAL module driver.
- *
- * This file provides firmware functions to manage the following
- * functionalities of the Digital to Analog Converter (DAC) peripheral:
- * + DAC channels configuration: trigger, output buffer, data format
- * + DMA management
- *
- *
- @verbatim
- ==============================================================================
- ##### DAC Peripheral features #####
- ==============================================================================
- [..]
- *** DAC Channels ***
- ====================
- [..]
- The device integrates 1 12-bit Digital Analog Converters:
- (#) DAC channel1 with DAC_OUT1 (PA4) as output
-
- *** DAC Triggers ***
- ====================
- [..]
- Digital to Analog conversion can be non-triggered using DAC_Trigger_None
- and DAC_OUT1/DAC_OUT2 is available once writing to DHRx register.
- [..]
- Digital to Analog conversion can be triggered by:
- (#) External event: EXTI Line 9 (any GPIOx_Pin9) using DAC_Trigger_Ext_IT9.
- The used pin (GPIOx_Pin9) must be configured in input mode.
-
- (#) Timers TRGO: TIM2, TIM6 and TIM21
- (DAC_Trigger_T2_TRGO, DAC_Trigger_T6_TRGO...)
-
- (#) Software using DAC_Trigger_Software
-
- *** DAC Buffer mode feature ***
- ===============================
- [..]
- Each DAC channel integrates an output buffer that can be used to
- reduce the output impedance, and to drive external loads directly
- without having to add an external operational amplifier.
- To enable, the output buffer use
- sConfig.DAC_OutputBuffer = DAC_OutputBuffer_Enable;
- [..]
- (@) Refer to the device datasheet for more details about output
- impedance value with and without output buffer.
-
- *** DAC wave generation feature ***
- ===================================
- [..]
- Both DAC channels can be used to generate
- (#) Noise wave using HAL_DAC_NoiseWaveGenerate()
- (#) Triangle wave using HAL_DAC_TriangleWaveGenerate()
-
- *** DAC data format ***
- =======================
- [..]
- The DAC data format can be:
- (#) 8-bit right alignment using DAC_ALIGN_8B_R
- (#) 12-bit left alignment using DAC_ALIGN_12B_L
- (#) 12-bit right alignment using DAC_ALIGN_12B_R
-
- *** DAC data value to voltage correspondence ***
- ================================================
- [..]
- The analog output voltage on each DAC channel pin is determined
- by the following equation:
- DAC_OUTx = VREF+ * DOR / 4095
- with DOR is the Data Output Register
- VEF+ is the input voltage reference (refer to the device datasheet)
- e.g. To set DAC_OUT1 to 0.7V, use
- Assuming that VREF+ = 3.3V, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V
-
- *** DMA requests ***
- =====================
- [..]
- A DMA1 request can be generated when an external trigger (but not
- a software trigger) occurs if DMA1 requests are enabled using
- HAL_DAC_Start_DMA()
- [..]
- DMA1 requests are mapped as following:
- (#) DAC channel1 : mapped on DMA1 Request9 channel2 which must be
- already configured
-
-
- ##### How to use this driver #####
- ==============================================================================
- [..]
- (+) DAC APB clock must be enabled to get write access to DAC
- registers using HAL_DAC_Init()
- (+) Configure DAC_OUTx (DAC_OUT1: PA4) in analog mode.
- (+) Configure the DAC channel using HAL_DAC_ConfigChannel() function.
- (+) Enable the DAC channel using HAL_DAC_Start() or HAL_DAC_Start_DMA functions

- * @author MCD Application Team
- * @version V1.0.0
- * @date 22-April-2014
- * @brief DMA HAL module driver.
- *
- * This file provides firmware functions to manage the following
- * functionalities of the Direct Memory Access (DMA) peripheral:
- * + Initialization/de-initialization functions
- * + I/O operation functions
- * + Peripheral State functions
- *
- *
- @verbatim
- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..]
- (#) Enable and configure the peripheral to be connected to the DMA Channel
- (except for internal SRAM / FLASH memories: no initialization is
- necessary).
-
- (#) For a given Channel, program the required configuration through the following parameters:
- Channel request, Transfer Direction, Source and Destination data formats,
- Circular, Normal or peripheral flow control mode, Channel Priority level,
- Source and Destination Increment mode using HAL_DMA_Init() function.
-
- *** Polling mode IO operation ***
- =================================
- [..]
- (+) Use HAL_DMA_Start() to start DMA transfer after the configuration of Source
- address and destination address and the Length of data to be transferred
- (+) Use HAL_DMA_PollForTransfer() to poll for the end of current transfer, in this
- case a fixed Timeout can be configured by User depending from his application.
-
- *** Interrupt mode IO operation ***
- ===================================
- [..]
- (+) Configure the DMA interrupt priority using HAL_NVIC_SetPriority()
- (+) Enable the DMA IRQ handler using HAL_NVIC_EnableIRQ()
- (+) Use HAL_DMA_Start_IT() to start DMA transfer after the configuration of
- Source address and destination address and the Length of data to be transferred. In this
- case the DMA interrupt is configured
- (+) Use HAL_DMA_IRQHandler() called under DMA_IRQHandler() Interrupt subroutine
- (+) At the end of data transfer HAL_DMA_IRQHandler() function is executed and user can
- add his own function by customization of function pointer XferCpltCallback and
- XferErrorCallback (i.e a member of DMA handle structure).
-
- (#) Use HAL_DMA_GetState() function to return the DMA state and HAL_DMA_GetError() in case of error
- detection.
-
- (#) Use HAL_DMA_Abort() function to abort the current transfer
-
- -@- In Memory-to-Memory transfer mode, Circular mode is not allowed.

- * @date 22-April-2014
- * @brief FLASH HAL module driver.
- * This file provides firmware functions to manage the following
- * functionalities of the internal FLASH memory:
- * + FLASH Interface configuration
- * + FLASH Memory Programming
- * + DATA EEPROM Programming
- * + Option Bytes Programming
- * + Interrupts and flags management
- *
- * @verbatim
-
- ==============================================================================
- ##### FLASH peripheral features #####
- ==============================================================================
-
- [..] The Flash memory interface manages CPU accesses to the Flash memory.
- It implements the erase and program Flash memory operations
- and the read and write protection mechanisms.
-
- [..] The FLASH main features are:
- (+) Flash memory read operations
- (+) Flash memory program/erase operations
- (+) Read / write protections
- (+) Option Bytes programming
-
- ##### How to use this driver #####
- ==============================================================================
- [..]
- This driver provides functions and macros to configure and program the FLASH
- memory of all STM32L0xx devices.
-
- (#) FLASH Memory IO Programming functions:
- (++) Lock and Unlock the FLASH interface using HAL_FLASH_Unlock() and
- HAL_FLASH_Lock() functions
- (++) Program functions: byte, half word and word
- (++) There Two modes of programming :
- (+++) Polling mode using HAL_FLASH_Program() function
- (+++) Interrupt mode using HAL_FLASH_Program_IT() function
-
- (#) Interrupts and flags management functions :
- (++) Handle FLASH interrupts by calling HAL_FLASH_IRQHandler()
- (++) Wait for last FLASH operation according to its status
- (++) Get error flag status by calling HAL_GetErrorCode()
-
- [..]
- In addition to these functions, this driver includes a set of macros allowing
- to handle the following operations:
- (+) Set the latency
- (+) Enable/Disable the prefetch buffer
- (+) Enable/Disable the preread buffer
- (+) Enable/Disable the Flash power-down
- (+) Enable/Disable the FLASH interrupts
- (+) Monitor the FLASH flags status
-
- ===============================================================================
- ##### Programming operation functions #####
- ===============================================================================
- [..]
- This subsection provides a set of functions allowing to manage the FLASH
- program operations.
-
- [..] The FLASH Memory Programming functions, includes the following functions:
- (+) HAL_FLASH_Unlock(void);
- (+) HAL_FLASH_Lock(void);
- (+) HAL_FLASH_Program(uint32_t TypeProgram, uint32_t Address, uint32_t Data)
- (+) HAL_FLASH_Program_IT(uint32_t TypeProgram, uint32_t Address, uint32_t Data)
-
- [..] Any operation of erase or program should follow these steps:
- (#) Call the HAL_FLASH_Unlock() function to enable the flash control register and
- program memory access.
- (#) Call the desired function to erase page or program data.
- (#) Call the HAL_FLASH_Lock() to disable the flash program memory access
- (recommended to protect the FLASH memory against possible unwanted operation).
-
- ==============================================================================
- ##### Option Bytes Programming functions #####
- ==============================================================================
-
- [..] The FLASH_Option Bytes Programming_functions, includes the following functions:
- (+) HAL_FLASH_OB_Unlock(void);
- (+) HAL_FLASH_OB_Lock(void);
- (+) HAL_FLASH_OB_Launch(void);
- (+) HAL_FLASHEx_OBProgram(FLASH_OBProgramInitTypeDef *pOBInit);
- (+) HAL_FLASHEx_OBGetConfig(FLASH_OBProgramInitTypeDef *pOBInit);
-
- [..] Any operation of erase or program should follow these steps:
- (#) Call the HAL_FLASH_OB_Unlock() function to enable the Flash option control
- register access.
- (#) Call the following functions to program the desired option bytes.
- (++) HAL_FLASHEx_OBProgram(FLASH_OBProgramInitTypeDef *pOBInit);
- (#) Once all needed option bytes to be programmed are correctly written, call the
- HAL_FLASH_OB_Launch(void) function to launch the Option Bytes programming process.
- (#) Call the HAL_FLASH_OB_Lock() to disable the Flash option control register access (recommended
- to protect the option Bytes against possible unwanted operations).
-
- [..] Proprietary code Read Out Protection (PcROP):
- (#) The PcROP sector is selected by using the same option bytes as the Write
- protection (nWRPi bits). As a result, these 2 options are exclusive each other.
- (#) In order to activate the PcROP (change the function of the nWRPi option bits),
- the SPRMOD option bit must be activated.
- (#) The active value of nWRPi bits is inverted when PCROP mode is active, this
- means: if SPRMOD = 1 and nWRPi = 1 (default value), then the user page "i"
- is read/write protected.
- (#) To activate PCROP mode for Flash page(s), you need to follow the sequence below:
- (++) For page(s) within the first 64KB of the Flash, use this function
- HAL_FLASHEx_AdvOBProgram with PCROPState = PCROPSTATE_ENABLE.

- * @brief GPIO HAL module driver.
- * This file provides firmware functions to manage the following
- * functionalities of the General Purpose Input/Output (GPIO) peripheral:
- * + Initialization and de-initialization functions
- * + IO operation functions
- *
- @verbatim
- ==============================================================================
- ##### GPIO Peripheral features #####
- ==============================================================================
- [..]
- (+) Each port bit of the general-purpose I/O (GPIO) ports can be individually
- configured by software in several modes:
- (++) Input mode
- (++) Analog mode
- (++) Output mode
- (++) Alternate function mode
- (++) External interrupt/event lines
-
- (+) During and just after reset, the alternate functions and external interrupt
- lines are not active and the I/O ports are configured in input floating mode.
-
- (+) All GPIO pins have weak internal pull-up and pull-down resistors, which can be
- activated or not.
-
- (+) In Output or Alternate mode, each IO can be configured on open-drain or push-pull
- type and the IO speed can be selected depending on the VDD value.
-
- (+) The microcontroller IO pins are connected to onboard peripherals/modules through a
- multiplexer that allows only one peripheral alternate function (AF) connected
- to an IO pin at a time. In this way, there can be no conflict between peripherals
- sharing the same IO pin.
-
- (+) All ports have external interrupt/event capability. To use external interrupt
- lines, the port must be configured in input mode. All available GPIO pins are
- connected to the 16 external interrupt/event lines from EXTI0 to EXTI15.
-
- (+) The external interrupt/event controller consists of up to 23 edge detectors
- (16 lines are connected to GPIO) for generating event/interrupt requests (each
- input line can be independently configured to select the type (interrupt or event)
- and the corresponding trigger event (rising or falling or both). Each line can
- also be masked independently.
-
- ##### How to use this driver #####
- ==============================================================================
- [..]
- (#) Enable the GPIO IOPORT clock using the following function: __GPIOx_CLK_ENABLE().
-
- (#) In case of external interrupt/event mode selection, enable the SYSCFG clock
- using the following function __SYSCFG_CLK_ENABLE().
-
- (#) Configure the GPIO pin(s) using HAL_GPIO_Init().
- (++) Configure the IO mode using "Mode" member from GPIO_InitTypeDef structure
- (++) Activate Pull-up, Pull-down resistor using "Pull" member from GPIO_InitTypeDef
- structure.
- (++) In case of Output or alternate function mode selection: the speed is
- configured through "Speed" member from GPIO_InitTypeDef structure.
- (++) In alternate mode is selection, the alternate function connected to the IO
- is configured through "Alternate" member from GPIO_InitTypeDef structure.
- (++) Analog mode is required when a pin is to be used as ADC channel
- or DAC output.
- (++) In case of external interrupt/event selection the "Mode" member from
- GPIO_InitTypeDef structure select the type (interrupt or event) and
- the corresponding trigger event (rising or falling or both).
-
- (#) In case of external interrupt/event mode selection, configure NVIC IRQ priority
- mapped to the EXTI line using HAL_NVIC_SetPriority() and enable it using
- HAL_NVIC_EnableIRQ().
-
- (#) To get the level of a pin configured in input mode use HAL_GPIO_ReadPin().
-
- (#) To set/reset the level of a pin configured in output mode use
- HAL_GPIO_WritePin()/HAL_GPIO_TogglePin().
-
- (#) During and just after reset, the alternate functions are not
- active and the GPIO pins are configured in input floating mode (except JTAG
- pins).
-
- (#) The LSE oscillator pins OSC32_IN and OSC32_OUT can be used as general purpose
- (PC14 and PC15, respectively) when the LSE oscillator is off. The LSE has
- priority over the GPIO function.
-
- (#) The HSE oscillator pins OSC_IN/OSC_OUT can be used as
- general purpose PH0 and PH1, respectively, when the HSE oscillator is off.
- The HSE has priority over the GPIO function.

- * @brief I2C HAL module driver.
- *
- * This file provides firmware functions to manage the following
- * functionalities of the Inter Integrated Circuit (I2C) peripheral:
- * + Initialization and de-initialization functions
- * + IO operation functions
- * + Peripheral State functions
- *
- @verbatim
- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..]
- The I2C HAL driver can be used as follows:
-
- (#) Declare a I2C_HandleTypeDef handle structure, for example:
- I2C_HandleTypeDef hi2c;
-
- (#)Initialize the I2C low level resources by implement the HAL_I2C_MspInit ()API:
- (##) Enable the I2Cx interface clock
- (##) I2C pins configuration
- (+++) Enable the clock for the I2C GPIOs
- (+++) Configure I2C pins as alternate function open-drain
- (##) NVIC configuration if you need to use interrupt process
- (+++) Configure the I2Cx interrupt priority
- (+++) Enable the NVIC I2C IRQ Channel
- (##) DMA Configuration if you need to use DMA process
- (+++) Declare a DMA_HandleTypeDef handle structure for the transmit or receive stream
- (+++) Enable the DMAx interface clock using
- (+++) Configure the DMA handle parameters
- (+++) Configure the DMA Tx or Rx Stream
- (+++) Associate the initilalized DMA handle to the hi2c DMA Tx or Rx handle
- (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx or Rx Stream
-
- (#) Configure the Communication Clock Timing, Own Address1, Master Adressing Mode, Dual Addressing mode,
- Own Address2, Own Address2 Mask, General call and Nostretch mode in the hi2c Init structure.
-
- (#) Initialize the I2C registers by calling the HAL_I2C_Init() API:
- (+++) These API's configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
- by calling the customed HAL_I2C_MspInit(&hi2c) API.
-
- (#) To check if target device is ready for communication, use the function HAL_I2C_IsDeviceReady()
-
- (#) For I2C IO and IO MEM operations, three mode of operations are available within this driver :
-
- *** Polling mode IO operation ***
- =================================
- [..]
- (+) Transmit in master mode an amount of data in blocking mode using HAL_I2C_Master_Transmit()
- (+) Receive in master mode an amount of data in blocking mode using HAL_I2C_Master_Receive()
- (+) Transmit in slave mode an amount of data in blocking mode using HAL_I2C_Slave_Transmit()
- (+) Receive in slave mode an amount of data in blocking mode using HAL_I2C_Slave_Receive()
-
- *** Polling mode IO MEM operation ***
- =====================================

- add his own code by customization of function pointer HAL_I2C_ErrorCallback
-
- *** Interrupt mode IO MEM operation ***
- =======================================
- [..]

-
- *** DMA mode IO operation ***
- ==============================
- [..]
- (+) Transmit in master mode an amount of data in non blocking mode (DMA) using

- * @brief IRDA HAL module driver.
- *
- * This file provides firmware functions to manage the following
- * functionalities of the IrDA (Infrared Data Association) Peripheral
- * (IRDA)
- * + Initialization and de-initialization functions
- * + IO operation functions
- * + Peripheral Control functions
- *
- *
- @verbatim
- ===============================================================================
- ##### How to use this driver #####
- ===============================================================================
- [..]
- The IRDA HAL driver can be used as follows:
-
-
- (#) Declare a IRDA_HandleTypeDef handle structure.
- (#) Initialize the IRDA low level resources by implementing the HAL_IRDA_MspInit() API:
- (##) Enable the USARTx interface clock.
- (##) IRDA pins configuration:
- (+) Enable the clock for the IRDA GPIOs.
- (+) Configure these IRDA pins as alternate function pull-up.
- (##) NVIC configuration if you need to use interrupt process (HAL_IRDA_Transmit_IT()
- and HAL_IRDA_Receive_IT() APIs):
- (+) Configure the USARTx interrupt priority.
- (+) Enable the NVIC USART IRQ handle.
- (##) DMA Configuration if you need to use DMA process (HAL_IRDA_Transmit_DMA()
- and HAL_IRDA_Receive_DMA() APIs):
- (+) Declare a DMA handle structure for the Tx/Rx stream.
- (+) Enable the DMAx interface clock.
- (+) Configure the declared DMA handle structure with the required Tx/Rx parameters.
- (+) Configure the DMA Tx/Rx Stream.
- (+) Associate the initilalized DMA handle to the IRDA DMA Tx/Rx handle.
- (+) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx Stream.
-
- (#) Program the Baud Rate, Word Length, Parity, IrDA Mode, Prescaler
- and Mode(Receiver/Transmitter) in the hirda Init structure.
-
- (#) Initialize the IRDA registers by calling the HAL_IRDA_Init() API:
- (++) This API configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
- by calling the customed HAL_IRDA_MspInit() API.
- -@@- The specific IRDA interrupts (Transmission complete interrupt,
- RXNE interrupt and Error Interrupts) will be managed using the macros
- __HAL_IRDA_ENABLE_IT() and __HAL_IRDA_DISABLE_IT() inside the transmit and receive process.
-
- (#) Three operation modes are available within this driver :
-
- *** Polling mode IO operation ***
- =================================
- [..]
- (+) Send an amount of data in blocking mode using HAL_IRDA_Transmit()
- (+) Receive an amount of data in blocking mode using HAL_IRDA_Receive()
-
- *** Interrupt mode IO operation ***
- ===================================
- [..]
- (+) Send an amount of data in non blocking mode using HAL_IRDA_Transmit_IT()
- (+) At transmission end of transfer HAL_IRDA_TxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_IRDA_TxCpltCallback
- (+) Receive an amount of data in non blocking mode using HAL_IRDA_Receive_IT()
- (+) At reception end of transfer HAL_IRDA_RxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_IRDA_RxCpltCallback
- (+) In case of transfer Error, HAL_IRDA_ErrorCallback() function is executed and user can
- add his own code by customization of function pointer HAL_IRDA_ErrorCallback
-
- *** DMA mode IO operation ***
- =============================
- [..]
- (+) Send an amount of data in non blocking mode (DMA) using HAL_IRDA_Transmit_DMA()
- (+) At transmission end of transfer HAL_IRDA_TxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_IRDA_TxCpltCallback
- (+) Receive an amount of data in non blocking mode (DMA) using HAL_IRDA_Receive_DMA()
- (+) At reception end of transfer HAL_IRDA_RxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_IRDA_RxCpltCallback
- (+) In case of transfer Error, HAL_IRDA_ErrorCallback() function is executed and user can
- add his own code by customization of function pointer HAL_IRDA_ErrorCallback
-
- *** IRDA HAL driver macros list ***
- ===================================
- [..]
- Below the list of most used macros in IRDA HAL driver.
-
- (+) __HAL_IRDA_ENABLE: Enable the IRDA peripheral
- (+) __HAL_IRDA_DISABLE: Disable the IRDA peripheral
- (+) __HAL_IRDA_GET_FLAG : Checks whether the specified IRDA flag is set or not
- (+) __HAL_IRDA_CLEAR_FLAG : Clears the specified IRDA pending flag
- (+) __HAL_IRDA_ENABLE_IT: Enables the specified IRDA interrupt
- (+) __HAL_IRDA_DISABLE_IT: Disables the specified IRDA interrupt
-
- (@) You can refer to the IRDA HAL driver header file for more useful macros

- ##### Initialization and Configuration functions #####
- ===============================================================================
- [..]
- This subsection provides a set of functions allowing to initialize the USARTx
- in asynchronous IRDA mode.
- (+) For the asynchronous mode only these parameters can be configured:
- (++) Baud Rate
- (++) Word Length
- (++) Parity: If the parity is enabled, then the MSB bit of the data written
- in the data register is transmitted but is changed by the parity bit.
- Depending on the frame length defined by the M bit (8-bits or 9-bits)
- or by the M1 and M0 bits (7-bit, 8-bit or 9-bit),
- the possible IRDA frame formats are as listed in the following table:
- +---------------------------------------------------------------+
- | M1M0 bits | PCE bit | IRDA frame |
- |-----------|-----------|---------------------------------------|
- | 00 | 0 | | SB | 8-bit data | STB | |
- |-----------|-----------|---------------------------------------|
- | 00 | 1 | | SB | 7-bit data | PB | STB | |
- |-----------|-----------|---------------------------------------|
- | 01 | 0 | | SB | 9-bit data | STB | |
- |-----------|-----------|---------------------------------------|
- | 01 | 1 | | SB | 8-bit data | PB | STB | |
- |-----------------------|---------------------------------------|
- | 10 | 0 | | SB | 7-bit data | STB | |
- |-----------|-----------|---------------------------------------|
- | 10 | 1 | | SB | 6-bit data | PB | STB | |
- +---------------------------------------------------------------+
-
- (++) Power mode
- (++) Prescaler setting
- (++) Receiver/transmitter modes
-
- [..]
- The HAL_IRDA_Init() API follows the USART asynchronous configuration procedures
- (details for the procedures are available in reference manual).

- ##### I/O operation functions #####
- ===============================================================================
- This subsection provides a set of functions allowing to manage the IRDA asynchronous
- data transfers.
-
- (#) There are two modes of transfer:
- (+) Blocking mode: the communication is performed in polling mode.
- The HAL status of all data processing is returned by the same function
- after finishing transfer.
- (+) No-Blocking mode: the communication is performed using Interrupts
- or DMA, these API's return the HAL status.
- The end of the data processing will be indicated through the
- dedicated IRDA IRQ when using Interrupt mode or the DMA IRQ when
- using DMA mode.
- The HAL_IRDA_TxCpltCallback(), HAL_IRDA_RxCpltCallback() user callbacks
- will be executed respectivelly at the end of the Transmit or Receive process
- The HAL_IRDA_ErrorCallback() user callback will be executed when a communication error is detected
-
- (#) Blocking mode API's are :
- (+) HAL_IRDA_Transmit()
- (+) HAL_IRDA_Receive()
-
- (#) Non-Blocking mode API's with Interrupt are :
- (+) HAL_IRDA_Transmit_IT()
- (+) HAL_IRDA_Receive_IT()
- (+) HAL_IRDA_IRQHandler()
- (+) IRDA_Transmit_IT()
- (+) IRDA_Receive_IT()
-
- (#) Non-Blocking mode functions with DMA are :
- (+) HAL_IRDA_Transmit_DMA()
- (+) HAL_IRDA_Receive_DMA()

- * @brief IWDG HAL module driver.
- * This file provides firmware functions to manage the following
- * functionalities of the Independent Watchdog (IWDG) peripheral:
- * + Initialization and de-initialization functions
- * + IO operation functions
- * + Peripheral State functions
- *
- @verbatim
- ==============================================================================
- ##### IWDG Generic features #####
- ==============================================================================
- [..]
- (+) The IWDG can be started by either software or hardware (configurable
- through option byte).
-
- (+) The IWDG is clocked by its own dedicated Low-Speed clock (LSI) and
- thus stays active even if the main clock fails.
- Once the IWDG is started, the LSI is forced ON and cannot be disabled
- (LSI cannot be disabled too), and the counter starts counting down from
- the reset value of 0xFFF. When it reaches the end of count value (0x000)
- a system reset is generated.
-
- (+) The IWDG counter should be refreshed at regular intervals, otherwise the
- watchdog generates an MCU reset when the counter reaches 0.
-
- (+) The IWDG is implemented in the VDD voltage domain that is still functional
- in STOP and STANDBY mode (IWDG reset can wake-up from STANDBY).
- IWDGRST flag in RCC_CSR register can be used to inform when an IWDG
- reset occurs.
-
- [..] Min-max timeout value @32KHz (LSI): ~0.512ms / ~32.0s
- The IWDG timeout may vary due to LSI frequency dispersion. STM32L0xx
- devices provide the capability to measure the LSI frequency (LSI clock
- connected internally to TIM5 CH4 input capture). The measured value
- can be used to have an IWDG timeout with an acceptable accuracy.
-
-
- ##### How to use this driver #####
- ==============================================================================
- [..]
- (#) if Window option is disabled
- (+) Use IWDG using HAL_IWDG_Init() function to :
- (++) Enable write access to IWDG_PR, IWDG_RLR.
- (++) Configure the IWDG prescaler, counter reload value.
- This reload value will be loaded in the IWDG counter each time the counter
- is reloaded, then the IWDG will start counting down from this value.
- (+) Use IWDG using HAL_IWDG_Start() function to :
- (++) Reload IWDG counter with value defined in the IWDG_RLR register.
- (++) Start the IWDG, when the IWDG is used in software mode (no need
- to enable the LSI, it will be enabled by hardware).
- (+) Then the application program must refresh the IWDG counter at regular
- intervals during normal operation to prevent an MCU reset, using
- HAL_IWDG_Refresh() function.
- (#) if Window option is enabled:
- (+) Use IWDG using HAL_IWDG_Start() function to enable IWDG downcounter
- (+) Use IWDG using HAL_IWDG_Init() function to :
- (++) Enable write access to IWDG_PR, IWDG_RLR and IWDG_WINR registers.
- (++) Configure the IWDG prescaler, reload value and window value.
- (+) Then the application program must refresh the IWDG counter at regular
- intervals during normal operation to prevent an MCU reset, using
- HAL_IWDG_Refresh() function.
-
- *** IWDG HAL driver macros list ***
- ====================================
- [..]
- Below the list of most used macros in IWDG HAL driver.
-
- (+) __HAL_IWDG_START: Enable the IWDG peripheral
- (+) __HAL_IWDG_RELOAD_COUNTER: Reloads IWDG counter with value defined in the reload register
- (+) __HAL_IWDG_ENABLE_WRITE_ACCESS : Enable write access to IWDG_PR and IWDG_RLR registers
- (+) __HAL_IWDG_DISABLE_WRITE_ACCESS : Disable write access to IWDG_PR and IWDG_RLR registers
- (+) __HAL_IWDG_GET_FLAG: Get the selected IWDG's flag status

- * @brief LCD Controller HAL module driver.
- * This file provides firmware functions to manage the following
- * functionalities of the LCD Controller (LCD) peripheral:
- * + Initialization/de-initialization methods
- * + I/O operation methods
- * + Peripheral State methods
- *
- @verbatim
- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..] The LCD HAL driver can be used as follows:
-
- (#) Declare a LCD_HandleTypeDef handle structure.
-
- (#) Initialize the LCD low level resources by implement the HAL_LCD_MspInit() API:
- (##) Enable the LCDCLK (same as RTCCLK): to configure the RTCCLK/LCDCLK, proceed as follows:
- (+) Enable the Power Controller (PWR) APB1 interface clock using the
- __PWR_CLK_ENABLE() macro.
- (+) Enable access to RTC domain using the HAL_PWR_EnableBkUpAccess() function.
- (+) Select the RTC clock source using the __HAL_RCC_RTC_CONFIG() function.
-
- (@) The frequency generator allows you to achieve various LCD frame rates
- starting from an LCD input clock frequency (LCDCLK) which can vary
- from 32 kHz up to 1 MHz.
- (##) LCD pins configuration:
- (+) Enable the clock for the LCD GPIOs.
- (+) Configure these LCD pins as alternate function no-pull.
- (##) Enable the LCD interface clock.
-
- (#) Program the Prescaler, Divider, Blink mode, Blink Frequency Duty, Bias,
- Voltage Source, Dead Time, Pulse On Duration and Contrast in the hlcd Init structure.
-
- (#) Initialize the LCD registers by calling the HAL_LCD_Init() API.
-
- (@) The HAL_LCD_Init() API configures also the low level Hardware GPIO, CLOCK, ...etc)
- by calling the custumed HAL_LCD_MspInit() API.
- (@) After calling the HAL_LCD_Init() the LCD RAM memory is cleared
-
- (#) Optionally you can update the LCD configuration using these macros:
- - LCD High Drive using the __HAL_LCD_HIGHDRIVER_ENABLE() and __HAL_LCD_HIGHDRIVER_DISABLE() macros
- - LCD Pulse ON Duration using the __HAL_LCD_PULSEONDURATION_CONFIG() macro
- - LCD Dead Time using the __HAL_LCD_DEADTIME_CONFIG() macro
- - The LCD Blink mode and frequency using the __HAL_LCD_BLINK_CONFIG() macro
- - The LCD Contrast using the __HAL_LCD_CONTRAST_CONFIG() macro
-
- (#) Write to the LCD RAM memory using the HAL_LCD_Write() API, this API can be called
- more time to update the different LCD RAM registers before calling
- HAL_LCD_UpdateDisplayRequest() API.
-
- (#) The HAL_LCD_Clear() API can be used to clear the LCD RAM memory.
-
- (#) When LCD RAM memory is updated enable the update display request using
- the HAL_LCD_UpdateDisplayRequest() API.
-
- [..] LCD and low power modes:
- (#) The LCD still active during STOP mode.

- ##### I/O operation methods #####
- ===============================================================================
- [..] Using its double buffer memory the LCD controller ensures the coherency of the
- displayed information without having to use interrupts to control LCD_RAM
- modification.
- The application software can access the first buffer level (LCD_RAM) through
- the APB interface. Once it has modified the LCD_RAM using the HAL_LCD_Write() API,
- it sets the UDR flag in the LCD_SR register using the HAL_LCD_UpdateDisplayRequest() API.
- This UDR flag (update display request) requests the updated information to be
- moved into the second buffer level (LCD_DISPLAY).
- This operation is done synchronously with the frame (at the beginning of the
- next frame), until the update is completed, the LCD_RAM is write protected and
- the UDR flag stays high.
- Once the update is completed another flag (UDD - Update Display Done) is set and
- generates an interrupt if the UDDIE bit in the LCD_FCR register is set.
- The time it takes to update LCD_DISPLAY is, in the worst case, one odd and one
- even frame.
- The update will not occur (UDR = 1 and UDD = 0) until the display is
- enabled (LCDEN = 1).

- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..]
- The LPTIM HAL driver can be used as follows:
-
- (#)Initialize the LPTIM low level resources by implementing the
- HAL_LPTIM_MspInit():
- (##) Enable the LPTIM interface clock using __LPTIM1_CLK_ENABLE().
- (##) In case of using interrupts (e.g. HAL_LPTIM_PWM_Start_IT()):
- (+) Configure the LPTIM interrupt priority using HAL_NVIC_SetPriority().
- (+) Enable the LPTIM IRQ handler using HAL_NVIC_EnableIRQ().
- (+) In LPTIM IRQ handler, call HAL_LPTIM_IRQHandler().
-
- (#)Initialize the LPTIM HAL using HAL_LPTIM_Init(). This function
- configures mainly:
- (##) The instance: Only LPTIM1 is present in STM32L053xx.
- (##) Clock: the counter clock.
- - Source : it can be either the ULPTIM input (IN1) or one of
- the internal clock; (APB, LSE, LSI or MSI).
- - Prescaler: select the clock divider.
- (##) UltraLowPowerClock : To be used only if the ULPTIM is selected
- as counter clock source.
- - Polarity: polarity of the active edge for the counter unit
- if the ULPTIM input is selected.
- - SampleTime: clock sampling time to configure the clock glitch
- filter.
- (##) Trigger: How the counter start.
- - Source: trigger can be software or one of the hardware triggers.
- - ActiveEdge : only for hardware trigger.
- - SampleTime : trigger sampling time to configure the trigger
- glitch filter.
- (##) OutputPolarity : 2 opposite polarities are possibles.
- (##) UpdateMode: specifies whether the update of the autoreload and
- the compare values is done immediately or after the end of current
- period.
-
- (#)Six modes are available:
-
- (##) PWM Mode: To generate a PWM signal with specified period and pulse,
- call HAL_LPTIM_PWM_Start() or HAL_LPTIM_PWM_Start_IT() for interruption
- mode.
-
- (##) One Pulse Mode: To generate pulse with specified width in response
- to a stimulus, call HAL_LPTIM_OnePulse_Start() or
- HAL_LPTIM_OnePulse_Start_IT() for interruption mode.
-
- (##) Set once Mode: In this mode, the output changes the level (from
- low level to high level if the output polarity is configured high, else
- the opposite) when a compare match occurs. To start this mode, call
- HAL_LPTIM_SetOnce_Start() or HAL_LPTIM_SetOnce_Start_IT() for
- interruption mode.
-
- (##) Encoder Mode: To use the encoder interface call
- HAL_LPTIM_Encoder_Start() or HAL_LPTIM_Encoder_Start_IT() for
- interruption mode.
-
- (##) Time out Mode: an active edge on one selected trigger input rests
- the counter. The first trigger event will start the timer, any
- successive trigger event will reset the counter and the timer will
- restart. To start this mode call HAL_LPTIM_TimeOut_Start_IT() or
- HAL_LPTIM_TimeOut_Start_IT() for interruption mode.
-
- (##) Counter Mode: counter can be used to count external events on
- the LPTIM Input1 or it can be used to count internal clock cycles.
- To start this mode, call HAL_LPTIM_Counter_Start() or
- HAL_LPTIM_Counter_Start_IT() for interruption mode.
-
-
- (#) User can stop any process by calling the corresponding API:
- HAL_LPTIM_Xxx_Stop() or HAL_LPTIM_Xxx_Stop_IT() if the process is
- already started in interruption mode.
-
- (#)Call HAL_LPTIM_DeInit() to deinitialize the LPTIM peripheral.

- * @brief PCD HAL module driver.
- * This file provides firmware functions to manage the following

- * + Initialization and de-initialization functions
- * + IO operation functions
- * + Peripheral Control functions
- * + Peripheral State functions

- @verbatim
- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..]
- The PCD HAL driver can be used as follows:
-
- (#) Declare a PCD_HandleTypeDef handle structure, for example:
- PCD_HandleTypeDef hpcd;
-
- (#) Fill parameters of Init structure in HCD handle
-
- (#) Call HAL_PCD_Init() API to initialize the HCD peripheral (Core, Device core, ...)
-
- (#) Initialize the PCD low level resources through the HAL_PCD_MspInit() API:
- (##) Enable the PCD/USB Low Level interface clock using
- (+++) __USB_CLK_ENABLE);
-
- (##) Initialize the related GPIO clocks
- (##) Configure PCD pin-out
- (##) Configure PCD NVIC interrupt
-
- (#)Associate the Upper USB device stack to the HAL PCD Driver:
- (##) hpcd.pData = pdev;
-
- (#)Enable HCD transmission and reception:
- (##) HAL_PCD_Start();
-

-@verbatim
-
- ===============================================================================
- ##### Peripheral Control functions #####
- ===============================================================================
-
- *** PVD configuration ***
- =========================
- [..]
- (+) The PVD is used to monitor the VDD power supply by comparing it to a
- threshold selected by the PVD Level (PLS[2:0] bits in the PWR_CR).
- (+) The PVD can use an external input analog voltage (PVD_IN) which is compared
- internally to VREFINT. The PVD_IN (PB7) has to be configured in Analog mode
- when PWR_PVDLevel_7 is selected (PLS[2:0] = 111).
-
- (+) A PVDO flag is available to indicate if VDD/VDDA is higher or lower
- than the PVD threshold. This event is internally connected to the EXTI
- line16 and can generate an interrupt if enabled. This is done through
- __HAL_PVD_EXTI_ENABLE_IT() macro.
- (+) The PVD is stopped in Standby mode.
-
- *** WakeUp pin configuration ***
- ================================
- [..]
- (+) WakeUp pin is used to wake up the system from Standby mode. This pin is
- forced in input pull-down configuration and is active on rising edges.
- (+) There are two WakeUp pins:
- WakeUp Pin 1 on PA.00.
- WakeUp Pin 2 on PC.13.
-
- [..]
- *** Main and Backup Regulators configuration ***
- ================================================
-
- (+) The main internal regulator can be configured to have a tradeoff between
- performance and power consumption when the device does not operate at
- the maximum frequency. This is done through __HAL_PWR_VOLTAGESCALING_CONFIG()
- macro which configure VOS bit in PWR_CR register:
- (++) When this bit is set (Regulator voltage output Scale 1 mode selected)
- the System frequency can go up to 32 MHz.
- (++) When this bit is reset (Regulator voltage output Scale 2 mode selected)
- the System frequency can go up to 16 MHz.
- (++) When this bit is reset (Regulator voltage output Scale 3 mode selected)
- the System frequency can go up to 4.2 MHz.
-
- Refer to the datasheets for more details.
-
- *** Low Power modes configuration ***
- =====================================
- [..]
- The device features 5 low-power modes:
- (+) Low power run mode: regulator in low power mode, limited clock frequency,
- limited number of peripherals running.
- (+) Sleep mode: Cortex-M0+ core stopped, peripherals kept running.
- (+) Low power sleep mode: Cortex-M0+ core stopped, limited clock frequency,
- limited number of peripherals running, regulator in low power mode.
- (+) Stop mode: All clocks are stopped, regulator running, regulator in low power mode.
- (+) Standby mode: VCORE domain powered off
-
- *** Low power run mode ***
- =========================
- [..]
- To further reduce the consumption when the system is in Run mode, the regulator can be
- configured in low power mode. In this mode, the system frequency should not exceed
- MSI frequency range1.
- In Low power run mode, all I/O pins keep the same state as in Run mode.
-
- (+) Entry:
- (++) VCORE in range2
- (++) Decrease the system frequency tonot exceed the frequency of MSI frequency range1.
- (++) The regulator is forced in low power mode using the HAL_PWREx_EnableLowPowerRunMode()
- function.
- (+) Exit:
- (++) The regulator is forced in Main regulator mode using the HAL_PWREx_DisableLowPowerRunMode()
- function.
- (++) Increase the system frequency if needed.
-
- *** Sleep mode ***
- ==================
- [..]
- (+) Entry:
- The Sleep mode is entered by using the HAL_PWR_EnterSLEEPMode(PWR_MAINREGULATOR_ON, PWR_SLEEPENTRY_WFx)
- functions with
- (++) PWR_SLEEPENTRY_WFI: enter SLEEP mode with WFI instruction
- (++) PWR_SLEEPENTRY_WFE: enter SLEEP mode with WFE instruction
-
- (+) Exit:
- (++) Any peripheral interrupt acknowledged by the nested vectored interrupt
- controller (NVIC) can wake up the device from Sleep mode.
-
- *** Low power sleep mode ***
- ============================
- [..]
- (+) Entry:
- The Low power sleep mode is entered by using the HAL_PWR_EnterSLEEPMode(PWR_LOWPOWERREGULATOR_ON, PWR_SLEEPENTRY_WFx)
- functions with
- (++) PWR_SLEEPENTRY_WFI: enter SLEEP mode with WFI instruction
- (++) PWR_SLEEPENTRY_WFE: enter SLEEP mode with WFE instruction
- (+) The Flash memory can be switched off by using the control bits (SLEEP_PD in the FLASH_ACR register.
- This reduces power consumption but increases the wake-up time.
-
- (+) Exit:
- (++) If the WFI instruction was used to enter Low power sleep mode, any peripheral interrupt
- acknowledged by the nested vectored interrupt controller (NVIC) can wake up the device
- from Low power sleep mode. If the WFE instruction was used to enter Low power sleep mode,
- the MCU exits Sleep mode as soon as an event occurs.
-
- *** Stop mode ***
- =================
- [..]
- The Stop mode is based on the Cortex-M0+ deepsleep mode combined with peripheral
- clock gating. The voltage regulator can be configured either in normal or low-power mode.
- In Stop mode, all clocks in the VCORE domain are stopped, the PLL, the MSI, the HSI and
- the HSE RC oscillators are disabled. Internal SRAM and register contents are preserved.
- To get the lowest consumption in Stop mode, the internal Flash memory also enters low
- power mode. When the Flash memory is in power-down mode, an additional startup delay is
- incurred when waking up from Stop mode.
- To minimize the consumption In Stop mode, VREFINT, the BOR, PVD, and temperature
- sensor can be switched off before entering Stop mode. They can be switched on again by
- software after exiting Stop mode using the ULP bit in the PWR_CR register.
- In Stop mode, all I/O pins keep the same state as in Run mode.
-
- (+) Entry:
- The Stop mode is entered using the HAL_PWR_EnterSTOPMode(PWR_MAINREGULATOR_ON, PWR_SLEEPENTRY_WFI )
- function with:
- (++) Main regulator ON.
- (++) Low Power regulator ON.
- (++) PWR_SLEEPENTRY_WFI: enter SLEEP mode with WFI instruction
- (++) PWR_SLEEPENTRY_WFE: enter SLEEP mode with WFE instruction

- (++) By issuing an interrupt or a wakeup event, the MSI or HSI16 RC
- oscillator is selected as system clock depending the bit STOPWUCK in the RCC_CFGR
- register
-
- *** Standby mode ***
- ====================
- [..]
- The Standby mode allows to achieve the lowest power consumption. It is based on the
- Cortex-M0+ deepsleep mode, with the voltage regulator disabled. The VCORE domain is
- consequently powered off. The PLL, the MSI, the HSI oscillator and the HSE oscillator are
- also switched off. SRAM and register contents are lost except for the RTC registers, RTC
- backup registers and Standby circuitry.
-
- To minimize the consumption In Standby mode, VREFINT, the BOR, PVD, and temperature
- sensor can be switched off before entering the Standby mode. They can be switched
- on again by software after exiting the Standby mode.

-
- (+) Entry:
- (++) The Standby mode is entered using the HAL_PWR_EnterSTANDBYMode() function.
- (+) Exit:
- (++) WKUP pin rising edge, RTC alarm (Alarm A and Alarm B), RTC wakeup,
- tamper event, time-stamp event, external reset in NRST pin, IWDG reset.
-
- *** Auto-wakeup (AWU) from low-power mode ***
- =============================================
- [..]
- The MCU can be woken up from low-power mode by an RTC Alarm event, an RTC
- Wakeup event, a tamper event, a time-stamp event, or a comparator event,
- without depending on an external interrupt (Auto-wakeup mode).
-
- (+) RTC auto-wakeup (AWU) from the Stop mode
- (++) To wake up from the Stop mode with an RTC alarm event, it is necessary to:
- (+++) Configure the EXTI Line 17 to be sensitive to rising edges (Interrupt
- or Event modes) using the EXTI_Init() function.
- (+++) Enable the RTC Alarm Interrupt using the RTC_ITConfig() function
- (+++) Configure the RTC to generate the RTC alarm using the RTC_SetAlarm()
- and RTC_AlarmCmd() functions.
- (++) To wake up from the Stop mode with an RTC Tamper or time stamp event, it
- is necessary to:
- (+++) Configure the EXTI Line 19 to be sensitive to rising edges (Interrupt
- or Event modes) using the EXTI_Init() function.
- (+++) Enable the RTC Tamper or time stamp Interrupt using the RTC_ITConfig()
- function.
- (+++) Configure the RTC to detect the tamper or time stamp event using the
- RTC_TimeStampConfig(), RTC_TamperTriggerConfig() and RTC_TamperCmd()
- functions.
- (++) To wake up from the Stop mode with an RTC WakeUp event, it is necessary to:
- (+++) Configure the EXTI Line 20 to be sensitive to rising edges (Interrupt
- or Event modes) using the EXTI_Init() function.
- (+++) Enable the RTC WakeUp Interrupt using the RTC_ITConfig() function.
- (+++) Configure the RTC to generate the RTC WakeUp event using the RTC_WakeUpClockConfig(),
- RTC_SetWakeUpCounter() and RTC_WakeUpCmd() functions.
-
- (+) RTC auto-wakeup (AWU) from the Standby mode
- (++) To wake up from the Standby mode with an RTC alarm event, it is necessary to:
- (+++) Enable the RTC Alarm Interrupt using the RTC_ITConfig() function.
- (+++) Configure the RTC to generate the RTC alarm using the RTC_SetAlarm()
- and RTC_AlarmCmd() functions.
- (++) To wake up from the Standby mode with an RTC Tamper or time stamp event, it
- is necessary to:
- (+++) Enable the RTC Tamper or time stamp Interrupt using the RTC_ITConfig()
- function.
- (+++) Configure the RTC to detect the tamper or time stamp event using the
- RTC_TimeStampConfig(), RTC_TamperTriggerConfig() and RTC_TamperCmd()
- functions.
- (++) To wake up from the Standby mode with an RTC WakeUp event, it is necessary to:
- (+++) Enable the RTC WakeUp Interrupt using the RTC_ITConfig() function
- (+++) Configure the RTC to generate the RTC WakeUp event using the RTC_WakeUpClockConfig(),
- RTC_SetWakeUpCounter() and RTC_WakeUpCmd() functions.
-
- (+) Comparator auto-wakeup (AWU) from the Stop mode
- (++) To wake up from the Stop mode with an comparator 1 or comparator 2 wakeup
- event, it is necessary to:
- (+++) Configure the EXTI Line 21 for comparator 1 or EXTI Line 22 for comparator 2
- to be sensitive to to the selected edges (falling, rising or falling
- and rising) (Interrupt or Event modes) using the EXTI_Init() function.
- (+++) Configure the comparator to generate the event.

- [..] After reset the device is running from MSI (2 MHz) with Flash 0 WS,
- all peripherals are off except internal SRAM, Flash and SW-DP.
- (+) There is no prescaler on High speed (AHB) and Low speed (APB) busses;
- all peripherals mapped on these busses are running at MSI speed.
- (+) The clock for all peripherals is switched off, except the SRAM and
- FLASH.
- (+) All GPIOs are in input floating state, except the SW-DP pins which
- are assigned to be used for debug purpose.
- [..] Once the device started from reset, the user application has to:
- (+) Configure the clock source to be used to drive the System clock
- (if the application needs higher frequency/performance)
- (+) Configure the System clock frequency and Flash settings
- (+) Configure the AHB and APB busses prescalers
- (+) Enable the clock for the peripheral(s) to be used
- (+) Configure the clock source(s) for peripherals whose clocks are not
- derived from the System clock (ADC, RTC/LCD, RNG and IWDG)

- ##### Initialization and de-initialization functions #####
- ===============================================================================
- [..]
- This section provide functions allowing to configure the internal/external
- clocks, PLL, CSS and MCO.
- [..] Internal/external clock and PLL configuration
- (#) HSI (high-speed internal), 16 MHz factory-trimmed RC used directly
- or through the PLL as System clock source.
- (#) MSI (multi-speed internal), multispeed low power RC
- (65.536 KHz to 4.194 MHz) MHz used as System clock source.
- (#) LSI (low-speed internal), 37 KHz low consumption RC used as IWDG
- and/or RTC clock source.
- (#) HSE (high-speed external), 1 to 24 MHz crystal oscillator used
- directly or through the PLL as System clock source. Can be used
- also as RTC clock source.
- (#) LSE (low-speed external), 32 KHz oscillator used as RTC clock source.
- (#) PLL (clocked by HSI or HSE), for System clock and USB (48 MHz).
- (#) CSS (Clock security system), once enable and if a HSE clock failure
- occurs (HSE used directly or through PLL as System clock source),
- the System clock is automatically switched to MSI and an interrupt
- is generated if enabled.
- The interrupt is linked to the Cortex-M3 NMI (Non-Maskable Interrupt)
- exception vector.
- (#) MCO (microcontroller clock output), used to output SYSCLK, HSI, MSI,
- HSE, PLL, LSI or LSE clock (through a configurable prescaler) on
- PA8 pin.
- [..] System, AHB and APB busses clocks configuration
- (#) Several clock sources can be used to drive the System clock (SYSCLK): MSI, HSI,
- HSE and PLL.
- The AHB clock (HCLK) is derived from System clock through configurable
- prescaler and used to clock the CPU, memory and peripherals mapped
- on IOPORT, AHB bus (DMA,Flash...). APB1 (PCLK1) and APB2 (PCLK2) clocks are derived
- from AHB clock through configurable prescalers and used to clock
- the peripherals mapped on these busses. You can use
- "HAL_RCC_GetSysClockFreq()" function to retrieve the frequencies of these clocks.
-
- -@- All the peripheral clocks are derived from the System clock (SYSCLK) except:
- (+@) I2S: the I2S clock can be derived from an external clock mapped on the I2S_CKIN pin.
-
- (+@) RTC: the RTC clock can be derived either from the LSI, LSE or HSE clock
- divided by 2 to 16. You have to use __HAL_RCC_RTC_CONFIG() and __HAL_RCC_RTC_ENABLE()
- macros to configure this clock.
- (+@) USB FS,and RNG require a frequency equal to 48 MHz to work correctly
- This clock is derived from the main PLL or HSI48 RC oscillator.
- (+@) IWDG clock which is always the LSI clock.
-
- (#) For the STM32L0xx devices, the maximum
- frequency of the SYSCLK ,HCLK, APB1 and APB2 is 32 MHz.
- Depending on the device voltage range, the maximum frequency should
- be adapted accordingly:
- ----------------------------------------------------------------
- | Wait states | HCLK clock frequency (MHz) |
- | |------------------------------------------------|
- | (Latency) | voltage range | voltage range |
- | | 1.65 V - 3.6 V | 2.0 V - 3.6 V |
- | |----------------|---------------|---------------|
- | | VCORE = 1.2 V | VCORE = 1.5 V | VCORE = 1.8 V |
- |-------------- |----------------|---------------|---------------|
- |0WS(1CPU cycle)|0 < HCLK <= 2 |0 < HCLK <= 8 |0 < HCLK <= 16 |
- |---------------|----------------|---------------|---------------|
- |1WS(2CPU cycle)|2 < HCLK <= 4 |8 < HCLK <= 16 |16 < HCLK <= 32|

- * @brief Extended RCC HAL module driver.
- *
- * This file provides firmware functions to manage the following
- * functionalities RCC extension peripheral:
- * + Extended Peripheral Control functions
- *
- @verbatim
- ==============================================================================
- ##### RCC specific features #####
- ==============================================================================
- For CRS, RCC Extension HAL driver can be used as follows:
-
- (#) In System clock configuration, HSI48 need to be enabled
-
- (#] Enable CRS clock in IP MSP init which will use CRS functions
-
- (#) Call CRS functions like this
- (##) Prepare synchronization configuration necessary for HSI48 calibration
- (+++) Default values can be set for frequency Error Measurement (reload and error limit)
- and also HSI48 oscillator smooth trimming.
- (+++) Macro __HAL_RCC_CRS_CALCULATE_RELOADVALUE can be also used to calculate
- directly reload value with target and synchronization frequencies values
- (##) Call function HAL_RCCEx_CRSConfig which
- (+++) Reset CRS registers to their default values.
- (+++) Configure CRS registers with synchronization configuration
- (+++) Enable automatic calibration and frequency error counter feature
-
- (##) A polling function is provided to wait for complete Synchronization
- (+++) Call function 'HAL_RCCEx_CRSWaitSynchronization()'
- (+++) According to CRS status, user can decide to adjust again the calibration or continue
- application if synchronization is OK
-
- (#) User can retrieve information related to synchronization in calling function
- HAL_RCCEx_CRSGetSynchronizationInfo()
-
- (#) Regarding synchronization status and synchronization information, user can try a new calibration
- in changing synchronization configuration and call again HAL_RCCEx_CRSConfig.
- Note: When the SYNC event is detected during the downcounting phase (before reaching the zero value),
- it means that the actual frequency is lower than the target (and so, that the TRIM value should be
- incremented), while when it is detected during the upcounting phase it means that the actual frequency
- is higher (and that the TRIM value should be decremented).
-
- (#) To use IT mode, user needs to handle it in calling different macros available to do it
- (__HAL_RCC_CRS_XXX_IT). Interruptions will go through RCC Handler (RCC_IRQn/RCC_CRS_IRQHandler)
- (+++) Call function HAL_RCCEx_CRSConfig()
- (+++) Enable RCC_IRQn (thnaks to NVIC functions)
- (+++) Enable CRS IT (__HAL_RCC_CRS_ENABLE_IT)
- [+++) Implement CRS status management in RCC_CRS_IRQHandler
-
- (#) To force a SYNC EVENT, user can use function 'HAL_RCCEx_CRSSoftwareSynchronizationGenerate()'. Function can be
- called before calling HAL_RCCEx_CRSConfig (for instance in Systick handler)

- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..]
- The RNG HAL driver can be used as follows:
-
- (#) Enable the RNG controller clock using __RNG_CLK_ENABLE() macro.
- (#) Activate the RNG peripheral using __HAL_RNG_ENABLE() macro.
- (#) Wait until the 32 bit Random Number Generator contains a valid
- random data using (polling/interrupt) mode.
- (#) Get the 32 bit random number using HAL_RNG_GetRandomNumber() function.

- * @brief RTC HAL module driver.
- * This file provides firmware functions to manage the following
- * functionalities of the Real Time Clock (RTC) peripheral:
- * + Initialization/de-initialization functions
- * + I/O operation functions
- * + Peripheral Control functions
- * + Peripheral State functions
- *
- @verbatim
- ==============================================================================
- ##### Backup Domain Operating Condition #####
- ==============================================================================
- [..] As long as the supply voltage remains in the operating range,
- the RTC never stops, regardless of the device status (Run mode,
- low power modes or under reset).
-
- ##### Backup Domain Reset #####
- ==================================================================
- [..] The backup domain reset sets all RTC registers and the RCC_CSR register
- to their reset values.
- [..] A backup domain reset is generated when one of the following events occurs:
- (+) Software reset, triggered by setting the RTCRST bit in the
- RCC Control Status register (RCC_CSR).
- (+) Power reset (BOR/POR/PDR).
-
- ##### Backup Domain Access #####
- ==================================================================
- [..] After reset, the backup domain (RTC registers and RTC backup data registers)
- is protected against possible unwanted write accesses.
- [..] To enable access to the RTC Domain and RTC registers, proceed as follows:
- (+) Enable the Power Controller (PWR) APB1 interface clock using the
- __PWR_CLK_ENABLE() function.
- (+) Enable access to RTC domain using the HAL_PWR_EnableBkUpAccess() function.
- (+) Select the RTC clock source using the __HAL_RCC_RTC_CONFIG() function.
- (+) Enable RTC Clock using the __HAL_RCC_RTC_ENABLE() function.
-
-
- ##### How to use this driver #####
- ==================================================================
- [..]
- (+) Enable the RTC domain access (see description in the section above).
- (+) Configure the RTC Prescaler (Asynchronous and Synchronous) and RTC hour
- format using the HAL_RTC_Init() function.
-
- *** Time and Date configuration ***
- ===================================
- [..]
- (+) To configure the RTC Calendar (Time and Date) use the HAL_RTC_SetTime()
- and HAL_RTC_SetDate() functions.
- (+) To read the RTC Calendar, use the HAL_RTC_GetTime() and HAL_RTC_GetDate() functions.
-
- *** Alarm configuration ***
- ===========================
- [..]
- (+) To configure the RTC Alarm use the HAL_RTC_SetAlarm() function.
- You can also configure the RTC Alarm with interrupt mode using the HAL_RTC_SetAlarm_IT() function.
- (+) To read the RTC Alarm, use the HAL_RTC_GetAlarm() function.
-
- *** RTC Wakeup configuration ***
- ================================
- [..]
- (+) To configure the RTC Wakeup Clock source and Counter use the HAL_RTC_SetWakeUpTimer()
- function. You can also configure the RTC Wakeup timer with interrupt mode
- using the HAL_RTC_SetWakeUpTimer_IT() function.
- (+) To read the RTC WakeUp Counter register, use the HAL_RTC_GetWakeUpTimer()
- function.
-
- *** Outputs configuration ***
- =============================
- [..] The RTC has 2 different outputs:
- (+) RTC_ALARM: this output is used to manage the RTC Alarm A, Alarm B
- and WaKeUp signals.
- To output the selected RTC signal, use the HAL_RTC_Init() function.
- (+) RTC_CALIB: this output is 512Hz signal or 1Hz.
- To enable the RTC_CALIB, use the HAL_RTCEx_SetCalibrationOutPut() function.
- (+) Two pins can be used as RTC_ALARM or RTC_CALIB (PC13, PB14) managed on
- the RTC_OR register.
- (+) When the RTC_CALIB or RTC_ALARM output is selected, the RTC_OUT pin is
- automatically configured in output alternate function.
-
- *** Smooth digital Calibration configuration ***
- ================================================
- [..]
- (+) Configure the RTC Original Digital Calibration Value and the corresponding
- calibration cycle period (32s,16s and 8s) using the HAL_RTCEx_SetSmoothCalib()
- function.
-
- *** TimeStamp configuration ***
- ===============================
- [..]
- (+) Enables the RTC TimeStamp using the HAL_RTC_SetTimeStamp() function.
- You can also configure the RTC TimeStamp with interrupt mode using the
- HAL_RTC_SetTimeStamp_IT() function.
- (+) To read the RTC TimeStamp Time and Date register, use the HAL_RTC_GetTimeStamp()
- function.
-
- *** Tamper configuration ***
- ============================
- [..]
- (+) Enable the RTC Tamper and Configure the Tamper filter count, trigger Edge
- or Level according to the Tamper filter (if equal to 0 Edge else Level)
- value, sampling frequency, NoErase, MaskFlag, precharge or discharge and
- Pull-UP using the HAL_RTC_SetTamper() function. You can configure RTC Tamper
- with interrupt mode using HAL_RTC_SetTamper_IT() function.
- (+) The default configuration of the Tamper erases the backup registers. To avoid
- erase, enable the NoErase field on the RTC_TAMPCR register.
-
- *** Backup Data Registers configuration ***
- ===========================================
- [..]
- (+) To write to the RTC Backup Data registers, use the HAL_RTC_BKUPWrite()
- function.
- (+) To read the RTC Backup Data registers, use the HAL_RTC_BKUPRead()
- function.
- (+) The backup registers are reset when a tamper detection event occurs
-
-
- ##### RTC and low power modes #####
- ==================================================================
- [..] The MCU can be woken up from a low power mode by an RTC alternate
- function.
- [..] The RTC alternate functions are the RTC alarms (Alarm A and Alarm B),
- RTC wakeup, RTC tamper event detection and RTC time stamp event detection.
- These RTC alternate functions can wake up the system from the Stop and
- Standby low power modes.
- [..] The system can also wake up from low power modes without depending
- on an external interrupt (Auto-wakeup mode), by using the RTC alarm
- or the RTC wakeup events.
- [..] The RTC provides a programmable time base for waking up from the
- Stop or Standby mode at regular intervals.
- Wakeup from STOP and Standby modes is possible only when the RTC clock source
- is LSE or LSI.

- ##### Initialization and de-initialization functions #####
- ===============================================================================
- [..] This section provides functions allowing to initialize and configure the
- RTC Prescaler (Synchronous and Asynchronous), RTC Hour format, disable
- RTC registers Write protection, enter and exit the RTC initialization mode,
- RTC registers synchronization check and reference clock detection enable.
- (#) The RTC Prescaler is programmed to generate the RTC 1Hz time base.
- It is split into 2 programmable prescalers to minimize power consumption.
- (++) A 7-bit asynchronous prescaler and a 13-bit synchronous prescaler.
- (++) When both prescalers are used, it is recommended to configure the
- asynchronous prescaler to a high value to minimize power consumption.
- (#) All RTC registers are Write protected. Writing to the RTC registers
- is enabled by writing a key into the Write Protection register, RTC_WPR.
- (#) To configure the RTC Calendar, user application should enter
- initialization mode. In this mode, the calendar counter is stopped
- and its value can be updated. When the initialization sequence is
- complete, the calendar restarts counting after 4 RTCCLK cycles.
- (#) To read the calendar through the shadow registers after Calendar
- initialization, calendar update or after wakeup from low power modes
- the software must first clear the RSF flag. The software must then
- wait until it is set again before reading the calendar, which means
- that the calendar registers have been correctly copied into the
- RTC_TR and RTC_DR shadow registers.The HAL_RTC_WaitForSynchro() function
- implements the above software sequence (RSF clear and RSF check).

- * @brief Extended RTC HAL module driver.
- *
- * This file provides firmware functions to manage the following
- * functionalities of the Real Time Clock (RTC) Extension peripheral:
- * + RTC Time Stamp functions
- * + RTC Tamper functions
- * + RTC Wake-up functions
- * + Extension Control functions
- * + Extension RTC features functions
- *
- @verbatim
- ==============================================================================
- ##### Backup Domain Operating Condition #####
- ==============================================================================
- [..] As long as the supply voltage remains in the operating range,
- the RTC never stops, regardless of the device status (Run mode,
- low power modes or under reset).
-
- ##### Backup Domain Reset #####
- ==================================================================
- [..] The backup domain reset sets all RTC registers and the RCC_CSR register
- to their reset values.
- [..] A backup domain reset is generated when one of the following events occurs:
- (+) Software reset, triggered by setting the RTCRST bit in the
- RCC Control Status register (RCC_CSR).
- (+) Power reset (BOR/POR/PDR).
-
- ##### Backup Domain Access #####
- ==================================================================
- [..] After reset, the backup domain (RTC registers and RTC backup data registers)
- is protected against possible unwanted write accesses.
- [..] To enable access to the RTC Domain and RTC registers, proceed as follows:
- (+) Enable the Power Controller (PWR) APB1 interface clock using the
- __PWR_CLK_ENABLE() function.
- (+) Enable access to RTC domain using the HAL_PWR_EnableBkUpAccess() function.
- (+) Select the RTC clock source using the __HAL_RCC_RTC_CONFIG() function.
- (+) Enable RTC Clock using the __HAL_RCC_RTC_ENABLE() function.
-
-
- ##### How to use this driver #####
- ==============================================================================
- [..]
- (+) Enable the RTC domain access.
- (+) Configure the RTC Prescaler (Asynchronous and Synchronous) and RTC hour
- format using the HAL_RTC_Init() function.
-
- *** Time and Date configuration ***
- ===================================
- [..]
- (+) To configure the RTC Calendar (Time and Date) use the HAL_RTC_SetTime()
- and HAL_RTC_SetDate() functions.
- (+) To read the RTC Calendar, use the HAL_RTC_GetTime() and HAL_RTC_GetDate() functions.
-
- *** Alarm configuration ***
- ===========================
- [..]
- (+) To configure the RTC Alarm use the HAL_RTC_SetAlarm() function.
- You can also configure the RTC Alarm with interrupt mode using the HAL_RTC_SetAlarm_IT() function.
- (+) To read the RTC Alarm, use the HAL_RTC_GetAlarm() function.
-
- *** RTC Wakeup configuration ***
- ================================
- [..]
- (+) To configure the RTC Wakeup Clock source and Counter use the HAL_RTC_SetWakeUpTimer()
- function. You can also configure the RTC Wakeup timer in interrupt mode
- using the HAL_RTC_SetWakeUpTimer_IT() function.
- (+) To read the RTC WakeUp Counter register, use the HAL_RTC_GetWakeUpTimer()
- function.
-
- *** Outputs configuration ***
- =============================
- [..] The RTC has 2 different outputs:
- (+) RTC_ALARM: this output is used to manage the RTC Alarm A, Alarm B
- and WaKeUp signals.
- To output the selected RTC signal, use the HAL_RTC_Init() function.
- (+) RTC_CALIB: this output is 512Hz signal or 1Hz.
- To enable the RTC_CALIB, use the HAL_RTCEx_SetCalibrationOutPut() function.
- (+) Two pins can be used as RTC_ALARM or RTC_CALIB (PC13, PB14) managed on
- the RTC_OR register.
- (+) When the RTC_CALIB or RTC_ALARM output is selected, the RTC_OUT pin is
- automatically configured in output alternate function.
-
- *** Smooth digital Calibration configuration ***
- ================================================
- [..]
- (+) Configure the RTC Original Digital Calibration Value and the corresponding
- calibration cycle period (32s,16s and 8s) using the HAL_RTCEx_SetSmoothCalib()
- function.
-
- *** TimeStamp configuration ***
- ===============================
- [..]
- (+) Enables the RTC TimeStamp using the HAL_RTC_SetTimeStamp() function.
- You can also configure the RTC TimeStamp with interrupt mode using the
- HAL_RTC_SetTimeStamp_IT() function.
- (+) To read the RTC TimeStamp Time and Date register, use the HAL_RTC_GetTimeStamp()
- function.
-
- *** Tamper configuration ***
- ============================
- [..]
- (+) Enable the RTC Tamper and Configure the Tamper filter count, trigger Edge
- or Level according to the Tamper filter (if equal to 0 Edge else Level)
- value, sampling frequency, NoErase, MaskFlag, precharge or discharge and
- Pull-UP using the HAL_RTC_SetTamper() function. You can configure RTC Tamper
- with interrupt mode using HAL_RTC_SetTamper_IT() function.
- (+) The default configuration of the Tamper erases the backup registers. To avoid
- erase, enable the NoErase field on the RTC_TAMPCR register.
-
- *** Backup Data Registers configuration ***
- ===========================================
- [..]
- (+) To write to the RTC Backup Data registers, use the HAL_RTC_BKUPWrite()
- function.
- (+) To read the RTC Backup Data registers, use the HAL_RTC_BKUPRead()
- function.
- (+) The backup registers are reset when a tamper detection event occurs
-
-
- ##### RTC and low power modes #####
- ==================================================================
- [..] The MCU can be woken up from a low power mode by an RTC alternate
- function.
- [..] The RTC alternate functions are the RTC alarms (Alarm A and Alarm B),
- RTC wakeup, RTC tamper event detection and RTC time stamp event detection.
- These RTC alternate functions can wake up the system from the Stop and
- Standby low power modes.
- [..] The system can also wake up from low power modes without depending
- on an external interrupt (Auto-wakeup mode), by using the RTC alarm
- or the RTC wakeup events.
- [..] The RTC provides a programmable time base for waking up from the
- Stop or Standby mode at regular intervals.
- Wakeup from STOP and Standby modes is possible only when the RTC clock source
- is LSE or LSI.

- *
- * This file provides firmware functions to manage the following
- * functionalities of the SmartCard.
- * + Initialization and de-initialization methods

- ===============================================================================
- ##### How to use this driver #####
- ===============================================================================
- [..]
- The SMARTCARD HAL driver can be used as follow:
-
- (#) Declare a SMARTCARD_HandleTypeDef handle structure.
- (#) Associate a USART to the SMARTCARD handle hsc.
- (#) Initialize the SMARTCARD low level resources by implementing the HAL_SMARTCARD_MspInit ()API:
- (##) Enable the USARTx interface clock.
- (##) USART pins configuration:
- (+) Enable the clock for the USART GPIOs.
- (+) Configure these USART pins as alternate function pull-up.
- (##) NVIC configuration if you need to use interrupt process (HAL_SMARTCARD_Transmit_IT()
- and HAL_SMARTCARD_Receive_IT() APIs):
- (+) Configure the USARTx interrupt priority.
- (+) Enable the NVIC USART IRQ handle.
- (@) The specific USART interrupts (Transmission complete interrupt,
- RXNE interrupt and Error Interrupts) will be managed using the macros
- __HAL_SMARTCARD_ENABLE_IT() and __HAL_SMARTCARD_DISABLE_IT() inside the transmit and receive process.
- (##) DMA Configuration if you need to use DMA process (HAL_SMARTCARD_Transmit_DMA()
- and HAL_SMARTCARD_Receive_DMA() APIs):
- (+) Declare a DMA handle structure for the Tx/Rx stream.
- (+) Enable the DMAx interface clock.
- (+) Configure the declared DMA handle structure with the required Tx/Rx parameters.
- (+) Configure the DMA Tx/Rx Stream.
- (+) Associate the initialized DMA handle to the SMARTCARD DMA Tx/Rx handle.
- (+) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx Stream.
-
- (#) Program the Baud Rate, Parity, Mode(Receiver/Transmitter), clock enabling/disabling and accordingly,
- the clock parameters (parity, phase, last bit), prescaler value, guard time and NACK on transmission
- error enabling or disabling in the hsc Init structure.
-
- (#) If required, program SMARTCARD advanced features (TX/RX pins swap, TimeOut, auto-retry counter,...)
- in the hsc AdvancedInit structure.
-
- (#) Initialize the SMARTCARD associated USART registers by calling
- the HAL_SMARTCARD_Init() API.
-
- (@) HAL_SMARTCARD_Init() API also configure also the low level Hardware GPIO, CLOCK, CORTEX...etc) by
- calling the customized HAL_SMARTCARD_MspInit() API.

- ##### I/O operation methods #####
- ===============================================================================
- This subsection provides a set of functions allowing to manage the SMARTCARD data transfers.
-
- (#) There are two mode of transfer:
- (+) Blocking mode: The communication is performed in polling mode.
- The HAL status of all data processing is returned by the same function
- after finishing transfer.
- (+) No-Blocking mode: The communication is performed using Interrupts
- or DMA, These API's return the HAL status.
- The end of the data processing will be indicated through the
- dedicated SMARTCARD IRQ when using Interrupt mode or the DMA IRQ when
- using DMA mode.
- The HAL_SMARTCARD_TxCpltCallback(), HAL_SMARTCARD_RxCpltCallback() user callbacks
- will be executed respectivelly at the end of the transmit or Receive process
- The HAL_SMARTCARD_ErrorCallback()user callback will be executed when a communication error is detected
-
- (#) Blocking mode API's are :
- (+) HAL_SMARTCARD_Transmit()
- (+) HAL_SMARTCARD_Receive()
-
- (#) Non-Blocking mode API's with Interrupt are :
- (+) HAL_SMARTCARD_Transmit_IT()
- (+) HAL_SMARTCARD_Receive_IT()
- (+) HAL_SMARTCARD_IRQHandler()
- (+) SMARTCARD_Transmit_IT()
- (+) SMARTCARD_Receive_IT()
-
- (#) No-Blocking mode functions with DMA are :
- (+) HAL_SMARTCARD_Transmit_DMA()
- (+) HAL_SMARTCARD_Receive_DMA()
-
- (#) A set of Transfer Complete Callbacks are provided in No_Blocking mode:
- (+) HAL_SMARTCARD_TxCpltCallback()
- (+) HAL_SMARTCARD_RxCpltCallback()
- (+) HAL_SMARTCARD_ErrorCallback()

- *
- @verbatim
- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..]
- The SMBUS HAL driver can be used as follows:
-
- (#) Declare a SMBUS_HandleTypeDef handle structure, for example:
- SMBUS_HandleTypeDef hsmbus;
-
- (#)Initialize the SMBUS low level resources by implement the HAL_SMBUS_MspInit ()API:
- (##) Enable the SMBUSx interface clock
- (##) SMBUS pins configuration
- (+) Enable the clock for the SMBUS GPIOs
- (+) Configure SMBUS pins as alternate function open-drain
- (##) NVIC configuration if you need to use interrupt process
- (+) Configure the SMBUSx interrupt priority
- (+) Enable the NVIC SMBUS IRQ Channel
-
- (#) Configure the Communication Clock Timing, Bus Timeout, Own Address1, Master Adressing Mode,
- Dual Addressing mode, Own Address2, Own Address2 Mask, General call, Nostretch mode,
- Peripheral mode and Packet Error Check mode in the hsmbus Init structure.
-
- (#) Initialize the SMBUS registers by calling the HAL_SMBUS_Init() API:
- (+) These API's configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
- by calling the customed HAL_SMBUS_MspInit(&hsmbus) API.
-
- (#) To check if target device is ready for communication, use the function HAL_SMBUS_IsDeviceReady()
-
- (#) For SMBUS IO operations, only one mode of operations is available within this driver :
-
- *** Interrupt mode IO operation ***
- ===================================
- [..]
- (+) Transmit in master/host SMBUS mode an amount of data in non blocking mode using HAL_SMBUS_Master_Transmit_IT()
- (++) At transmission end of transfer HAL_SMBUS_MasterTxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_SMBUS_MasterTxCpltCallback
- (+) Receive in master/host SMBUS mode an amount of data in non blocking mode using HAL_SMBUS_Master_Receive_IT()
- (++) At reception end of transfer HAL_SMBUS_MasterRxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_SMBUS_MasterRxCpltCallback
- (+) Abort a master/host SMBUS process commnunication with Interrupt using HAL_SMBUS_Master_Abort_IT()
- (++) The associated previous transfer callback is called at the end of abort process
- (++) mean HAL_SMBUS_MasterTxCpltCallback in case of previous state was master transmit
- (++) mean HAL_SMBUS_MasterRxCpltCallback in case of previous state was master receive
- (+) Enable the Address listen mode in slave/device SMBUS mode using HAL_SMBUS_Slave_Listen_IT()
- (++) When address slave/device SMBUS match, HAL_SMBUS_SlaveAddrCallback is executed and user can
- add his own code to check the Address Match Code and the transmission direction request by master/host (Write/Read).
- (++) At Listen mode end HAL_SMBUS_SlaveListenCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_SMBUS_SlaveListenCpltCallback
- (+) Transmit in slave/device SMBUS mode an amount of data in non blocking mode using HAL_SMBUS_Slave_Transmit_IT()
- (++) At transmission end of transfer HAL_SMBUS_SlaveTxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_SMBUS_SlaveTxCpltCallback
- (+) Receive in slave/device SMBUS mode an amount of data in non blocking mode using HAL_SMBUS_Slave_Receive_IT()
- (++) At reception end of transfer HAL_SMBUS_SlaveRxCpltCallback is executed and user can

- * @brief SPI HAL module driver.
- *
- * This file provides firmware functions to manage the following
- * functionalities of the Serial Peripheral Interface (SPI) peripheral:
- * + Initialization and de-initialization functions
- * + IO operation functions
- * + Peripheral Control functions
- * + Peripheral State functions
- @verbatim
- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..]
- The SPI HAL driver can be used as follows:
-
- (#) Declare a SPI_HandleTypeDef handle structure, for example:
- SPI_HandleTypeDef hspi;
-
- (#)Initialize the SPI low level resources by implement the HAL_SPI_MspInit ()API:
- (##) Enable the SPIx interface clock
- (##) SPI pins configuration
- (+) Enable the clock for the SPI GPIOs
- (+) Configure these SPI pins as alternate function push-pull
- (##) NVIC configuration if you need to use interrupt process
- (+) Configure the SPIx interrupt priority
- (+) Enable the NVIC SPI IRQ handle
- (##) DMA Configuration if you need to use DMA process
- (+) Declare a DMA_HandleTypeDef handle structure for the transmit or receive stream
- (+) Enable the DMAx interface clock using
- (+) Configure the DMA handle parameters
- (+) Configure the DMA Tx or Rx Stream
- (+) Associate the initilalized hdma_tx handle to the hspi DMA Tx or Rx handle
- (+) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx or Rx Stream
-
- (#) Program the Mode, Direction , Data size, Baudrate Prescaler, NSS
- management, Clock polarity and phase, FirstBit and CRC configuration in the hspi Init structure.
-
- (#) Initialize the SPI registers by calling the HAL_SPI_Init() API:
- (+) This API configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
- by calling the customed HAL_SPI_MspInit(&hspi) API.
- [..]
- Using the HAL it is not possible to reach all supported SPI frequency with the differents SPI Modes,
- the following table resume the max SPI frequency reached with data size 8bits/16bits:
- +-----------------------------------------------------------------------------------------+
- | | | 2Lines Fullduplex | 2Lines RxOnly | 1Line |
- | Process | Tranfert mode |--------------------|--------------------|--------------------|

- | X |----------------|----------|---------|----------|---------|----------|---------|
- | / | Interrupt | Fcpu/4 | Fcpu/16 | NA | NA | NA | NA |
- | R |----------------|----------|---------|----------|---------|----------|---------|
- | X | DMA | Fcpu/2 | Fcpu/2 | NA | NA | NA | NA |

- | X |----------------|----------|---------|----------|---------|----------|---------|
- | | DMA | Fcpu/2 | Fcpu/2 | NA | NA | Fcpu/8 | Fcpu/16 |
- +-----------------------------------------------------------------------------------------+
- @note The max SPI frequency depend on SPI data size (4bits, 5bits,..., 8bits,...15bits, 16bits),
- SPI mode(2 Lines fullduplex, 2 lines RxOnly, 1 line TX/RX) and Process mode (Polling, IT, DMA).
- @note
- (#) TX/RX processes are HAL_SPI_TransmitReceive(), HAL_SPI_TransmitReceive_IT() and HAL_SPI_TransmitReceive_DMA()
- (#) RX processes are HAL_SPI_Receive(), HAL_SPI_Receive_IT() and HAL_SPI_Receive_DMA()
- (#) TX processes are HAL_SPI_Transmit(), HAL_SPI_Transmit_IT() and HAL_SPI_Transmit_DMA()

- ==============================================================================
- ##### IO operation functions #####
- ===============================================================================
- This subsection provides a set of functions allowing to manage the SPI
- data transfers.
-
- [..] The SPI supports master and slave mode :
-
- (#) There are two mode of transfer:
- (+) Blocking mode: The communication is performed in polling mode.
- The HAL status of all data processing is returned by the same function
- after finishing transfer.
- (+) No-Blocking mode: The communication is performed using Interrupts
- or DMA, These API's return the HAL status.
- The end of the data processing will be indicated through the
- dedicated SPI IRQ when using Interrupt mode or the DMA IRQ when
- using DMA mode.
- The HAL_SPI_TxCpltCallback(), HAL_SPI_RxCpltCallback() and HAL_SPI_TxRxCpltCallback() user callbacks
- will be executed respectivelly at the end of the transmit or Receive process
- The HAL_SPI_ErrorCallback()user callback will be executed when a communication error is detected
-
- (#) Blocking mode API's are :
- (+) HAL_SPI_Transmit()in 1Line (simplex) and 2Lines (full duplex) mode
- (+) HAL_SPI_Receive() in 1Line (simplex) and 2Lines (full duplex) mode
- (+) HAL_SPI_TransmitReceive() in full duplex mode
-
- (#) Non-Blocking mode API's with Interrupt are :
- (+) HAL_SPI_Transmit_IT()in 1Line (simplex) and 2Lines (full duplex) mode
- (+) HAL_SPI_Receive_IT() in 1Line (simplex) and 2Lines (full duplex) mode
- (+) HAL_SPI_TransmitReceive_IT()in full duplex mode
- (+) HAL_SPI_IRQHandler()
-
- (#) No-Blocking mode functions with DMA are :
- (+) HAL_SPI_Transmit_DMA()in 1Line (simplex) and 2Lines (full duplex) mode
- (+) HAL_SPI_Receive_DMA() in 1Line (simplex) and 2Lines (full duplex) mode
- (+) HAL_SPI_TransmitReceie_DMA() in full duplex mode
-
- (#) A set of Transfer Complete Callbacks are provided in No_Blocking mode:
- (+) HAL_SPI_TxCpltCallback()
- (+) HAL_SPI_RxCpltCallback()
- (+) HAL_SPI_ErrorCallback()
- (+) HAL_SPI_TxRxCpltCallback()

- ==============================================================================
- ##### TIMER Generic features #####
- ==============================================================================
- [..] The Timer features include:
- (#) 16-bit up, down, up/down auto-reload counter.
- (#) 16-bit programmable prescaler allowing dividing (also on the fly) the counter clock
- frequency either by any factor between 1 and 65536.
- (#) Up to 4 independent channels for:
- Input Capture
- Output Compare
- PWM generation (Edge and Center-aligned Mode)
- One-pulse mode output
- (#) Synchronization circuit to control the timer with external signals and to interconnect
- several timers together.
- (#) Supports incremental (quadrature) encoder and hall-sensor circuitry for positioning
- purposes
-
- ##### How to use this driver #####
-================================================================================
- [..]
- (#) Enable the TIM interface clock using
- __TIMx_CLK_ENABLE();
-
- (#) TIM pins configuration
- (++) Enable the clock for the TIM GPIOs using the following function:
- __GPIOx_CLK_ENABLE();
- (++) Configure these TIM pins in Alternate function mode using HAL_GPIO_Init();
-
- (#) The external Clock can be configured, if needed (the default clock is the internal clock from the APBx),
- using the following function:
- HAL_TIM_ConfigClockSource, the clock configuration should be done before any start function.
-
- (#) Configure the TIM in the desired functioning mode using one of the
- initialization function of this driver:
- (++) HAL_TIM_Base_Init: to use the Timer to generate a simple time base
- (++) HAL_TIM_OC_Init and HAL_TIM_OC_ConfigChannel: to use the Timer to generate an
- Output Compare signal.
- (++) HAL_TIM_PWM_Init and HAL_TIM_PWM_ConfigChannel: to use the Timer to generate a
- PWM signal.
- (++) HAL_TIM_IC_Init and HAL_TIM_IC_ConfigChannel: to use the Timer to measure an
- external signal.
- (++) HAL_TIM_OnePulse_Init and HAL_TIM_OnePulse_ConfigChannel: to use the Timer in One Pulse Mode.
- (++) HAL_TIM_Encoder_Init: to use the Timer Encoder Interface.
-
- (#) Activate the TIM peripheral using one of the start functions:
- HAL_TIM_Base_Start(), HAL_TIM_Base_Start_DMA(), HAL_TIM_Base_Start_IT(),
- HAL_TIM_OC_Start(), HAL_TIM_OC_Start_DMA(), HAL_TIM_OC_Start_IT(),
- HAL_TIM_IC_Start(), HAL_TIM_IC_Start_DMA(), HAL_TIM_IC_Start_IT(),
- HAL_TIM_PWM_Start(), HAL_TIM_PWM_Start_DMA(), HAL_TIM_PWM_Start_IT(),
- HAL_TIM_OnePulse_Start(), HAL_TIM_OnePulse_Start_IT(),
- HAL_TIM_Encoder_Start(), HAL_TIM_Encoder_Start_DMA() or HAL_TIM_Encoder_Start_IT()
-
- (#) The DMA Burst is managed with the two following functions:
- HAL_TIM_DMABurst_WriteStart
- HAL_TIM_DMABurst_ReadStart

- * @file stm32l0xx_hal_tim_ex.c
- * @author MCD Application Team
- * @version V1.0.0
- * @date 22-April-2014
- * @brief TIM HAL module driver.
- * @brief This file provides firmware functions to manage the following
- * functionalities of the Timer (TIM) peripheral:
- * + Time Hall Sensor Interface Initialization
- * + Time Hall Sensor Interface Start
- * + Time Master and Slave synchronization configuration
- @verbatim
-================================================================================
- ##### <Product specific features/integration> #####
-================================================================================
-
- [..] The Timer features include:
- (#) 16-bit up, down, up/down auto-reload counter.
- (#) 16-bit programmable prescaler allowing dividing (also on the fly) the counter clock
- frequency either by any factor between 1 and 65536.
- (#) Up to 4 independent channels for:
- Input Capture
- Output Compare
- PWM generation (Edge and Center-aligned Mode)
- One-pulse mode output
- (#) Synchronization circuit to control the timer with external signals and to interconnect
- several timers together.
- (#) Supports incremental (quadrature) encoder and hall-sensor circuitry for positioning
- purposes
-
- ##### How to use this driver #####
-================================================================================
- [..]
- (#) Enable the TIM interface clock using
- __TIMx_CLK_ENABLE();
-
- (#) TIM pins configuration
- (++) Enable the clock for the TIM GPIOs using the following function:
- __GPIOx_CLK_ENABLE();
- (++) Configure these TIM pins in Alternate function mode using HAL_GPIO_Init();
-
- (#) The external Clock can be configured, if needed (the default clock is the internal clock from the APBx),
- using the following function:
- HAL_TIM_ConfigClockSource, the clock configuration should be done before any start function.
-
- (#) Configure the TIM in the desired operating mode using one of the
- configuration function of this driver:
- (++) HAL_TIMEx_MasterConfigSynchronization() to configure the peripheral in master mode.
-
- (#) Remap the Timer I/O using HAL_TIMEx_RemapConfig() API.

- * @file stm32l0xx_hal_tsc.c
- * @author MCD Application Team
- * @version V1.0.0
- * @date 22-April-2014
- * @brief This file provides firmware functions to manage the following
- * functionalities of the Touch Sensing Controller (TSC) peripheral:
- * + Initialization and DeInitialization
- * + Channel IOs, Shield IOs and Sampling IOs configuration
- * + Start and Stop an acquisition
- * + Read acquisition result
- * + Interrupts and flags management
- *
- @verbatim
-================================================================================
- ##### TSC specific features #####
-================================================================================
- [..]
- (#) Proven and robust surface charge transfer acquisition principle
-
- (#) Supports up to 3 capacitive sensing channels per group
-
- (#) Capacitive sensing channels can be acquired in parallel offering a very good
- response time
-
- (#) Spread spectrum feature to improve system robustness in noisy environments
-
- (#) Full hardware management of the charge transfer acquisition sequence
-
- (#) Programmable charge transfer frequency
-
- (#) Programmable sampling capacitor I/O pin
-
- (#) Programmable channel I/O pin
-
- (#) Programmable max count value to avoid long acquisition when a channel is faulty
-
- (#) Dedicated end of acquisition and max count error flags with interrupt capability
-
- (#) One sampling capacitor for up to 3 capacitive sensing channels to reduce the system
- components
-
- (#) Compatible with proximity, touchkey, linear and rotary touch sensor implementation
-
-
- ##### How to use this driver #####
-================================================================================
- [..]
- (#) Enable the TSC interface clock using __TSC_CLK_ENABLE() macro.
-
- (#) GPIO pins configuration
- (++) Enable the clock for the TSC GPIOs using __GPIOx_CLK_ENABLE() macro.
- (++) Configure the TSC pins used as sampling IOs in alternate function output Open-Drain mode,
- and TSC pins used as channel/shield IOs in alternate function output Push-Pull mode
- using HAL_GPIO_Init() function.
- (++) Configure the alternate function on all the TSC pins using HAL_xxxx() function.
-
- (#) Interrupts configuration
- (++) Configure the NVIC (if the interrupt model is used) using HAL_xxx() function.
-
- (#) TSC configuration
- (++) Configure all TSC parameters and used TSC IOs using HAL_TSC_Init() function.
-
- *** Acquisition sequence ***
- ===================================
- [..]
- (+) Discharge all IOs using HAL_TSC_IODischarge() function.
- (+) Wait a certain time allowing a good discharge of all capacitors. This delay depends
- of the sampling capacitor and electrodes design.
- (+) Select the channel IOs to be acquired using HAL_TSC_IOConfig() function.
- (+) Launch the acquisition using either HAL_TSC_Start() or HAL_TSC_Start_IT() function.
- If the synchronized mode is selected, the acquisition will start as soon as the signal
- is received on the synchro pin.
- (+) Wait the end of acquisition using either HAL_TSC_PollForAcquisition() or
- HAL_TSC_GetState() function or using WFI instruction for example.
- (+) Check the group acquisition status using HAL_TSC_GroupGetStatus() function.
- (+) Read the acquisition value using HAL_TSC_GroupGetValue() function.

- *
- * This file provides firmware functions to manage the following
- * functionalities of the Universal Asynchronous Receiver Transmitter Peripheral (UART).
- * + Initialization and de-initialization methods
- * + IO operation methods
- * + Peripheral Control methods
- *
- @verbatim
- ===============================================================================
- ##### How to use this driver #####
- ===============================================================================
- [..]
- The UART HAL driver can be used as follows:
-
- (#) Declare a UART_HandleTypeDef handle structure.
-
- (#) Initialize the UART low level resources by implementing the HAL_UART_MspInit() API:
- (##) Enable the USARTx interface clock.
- (##) UART pins configuration:
- (+++) Enable the clock for the UART GPIOs.
- (+++) Configure these UART pins as alternate function pull-up.
- (##) NVIC configuration if you need to use interrupt process (HAL_UART_Transmit_IT()
- and HAL_UART_Receive_IT() APIs):
- (+++) Configure the USARTx interrupt priority.
- (+++) Enable the NVIC USART IRQ handle.
-
- (##) DMA Configuration if you need to use DMA process (HAL_UART_Transmit_DMA()
- and HAL_UART_Receive_DMA() APIs):
- (+++) Declare a DMA handle structure for the Tx/Rx stream.
- (+++) Enable the DMAx interface clock.
- (+++) Configure the declared DMA handle structure with the required
- Tx/Rx parameters.
- (+++) Configure the DMA Tx/Rx Stream.
- (+++) Associate the initialized DMA handle to the UART DMA Tx/Rx handle.
- (+++) Configure the priority and enable the NVIC for the transfer complete
- interrupt on the DMA Tx/Rx Stream.
-
- (#) Program the Baud Rate, Word Length, Stop Bit, Parity, Hardware
- flow control and Mode(Receiver/Transmitter) in the Init structure.
-
- (#) For the UART asynchronous mode, initialize the UART registers by calling
- the HAL_UART_Init() API.
-
- (#) For the UART Half duplex mode, initialize the UART registers by calling
- the HAL_HalfDuplex_Init() API.
-
- (#) For the LIN mode, initialize the UART registers by calling the HAL_LIN_Init() API.
-
- (#) For the Multi-Processor mode, initialize the UART registers by calling
- the HAL_MultiProcessor_Init() API.
-
- [..]
- (@) The specific UART interrupts (Transmission complete interrupt,
- RXNE interrupt and Error Interrupts) will be managed using the macros
- __HAL_UART_ENABLE_IT() and __HAL_UART_DISABLE_IT() inside the transmit
- and receive process.
-
- [..]
- (@) These APIs (HAL_UART_Init() and HAL_HalfDuplex_Init()) configure also the
- low level Hardware GPIO, CLOCK, CORTEX...etc) by calling the customed
- HAL_UART_MspInit() API.
-
- [..]
- Three operation modes are available within this driver :
-
- *** Polling mode IO operation ***

- (+) Send an amount of data in blocking mode using HAL_UART_Transmit()
- (+) Receive an amount of data in blocking mode using HAL_UART_Receive()
-
- *** Interrupt mode IO operation ***

- ##### Initialization and Configuration functions #####
- ===============================================================================
- [..]
- This subsection provides a set of functions allowing to initialize the USARTx or the UARTy
- in asynchronous mode.
- (+) For the asynchronous mode only these parameters can be configured:
- (++) Baud Rate
- (++) Word Length
- (++) Stop Bit
- (++) Parity: If the parity is enabled, then the MSB bit of the data written
- in the data register is transmitted but is changed by the parity bit.
- Depending on the frame length defined by the M bit (8-bits or 9-bits),
- the possible UART frame formats are as listed in the following table:
- +-----------------------------------------------------------------------+
- | M1 bit | M0 bit | PCE bit | USART frame |
- |---------|---------|-----------|---------------------------------------|
- | 0 | 0 | 0 | | SB | 8 bit data | STB | |
- |---------|---------|-----------|---------------------------------------|
- | 0 | 0 | 1 | | SB | 7 bit data | PB | STB | |
- |---------|---------|-----------|---------------------------------------|
- | 0 | 1 | 0 | | SB | 9 bit data | STB | |
- |---------|---------|-----------|---------------------------------------|
- | 0 | 1 | 1 | | SB | 8 bit data | PB | STB | |
- |---------|---------|-----------|---------------------------------------|
- | 1 | 0 | 0 | | SB | 7 bit data | STB | |
- |---------|---------|-----------|---------------------------------------|
- | 1 | 0 | 1 | | SB | 6 bit data | PB | STB | |
- +-----------------------------------------------------------------------+
- (++) Hardware flow control
- (++) Receiver/transmitter modes
- (++) Over Sampling Method
- (++) One-Bit Sampling Method
- (+) For the asynchronous mode, the following advanced features can be configured as well:
- (++) TX and/or RX pin level inversion
- (++) data logical level inversion
- (++) RX and TX pins swap
- (++) RX overrun detection disabling
- (++) DMA disabling on RX error
- (++) MSB first on communication line
- (++) auto Baud rate detection
- [..]
- The HAL_UART_Init(), HAL_HalfDuplex_Init(), HAL_LIN_Init()and HAL_MultiProcessorEx_Init()API
- follow respectively the UART asynchronous, UART Half duplex, UART LIN mode
- and UART multiprocessor mode mode configuration procedures (details for the procedures
- are available in reference manual).

- ===============================================================================
- ##### I/O operation methods #####
- ===============================================================================
- This subsection provides a set of functions allowing to manage the UART asynchronous
- and Half duplex data transfers.
-
- (#) There are two mode of transfer:
- (+) Blocking mode: The communication is performed in polling mode.
- The HAL status of all data processing is returned by the same function
- after finishing transfer.
- (+) No-Blocking mode: The communication is performed using Interrupts
- or DMA, These API's return the HAL status.
- The end of the data processing will be indicated through the
- dedicated UART IRQ when using Interrupt mode or the DMA IRQ when
- using DMA mode.
- The HAL_UART_TxCpltCallback(), HAL_UART_RxCpltCallback() user callbacks
- will be executed respectivelly at the end of the transmit or Receive process
- The HAL_UART_ErrorCallback()user callback will be executed when a communication error is detected
-
- (#) Blocking mode API's are :
- (+) HAL_UART_Transmit()
- (+) HAL_UART_Receive()
-
- (#) Non-Blocking mode API's with Interrupt are :
- (+) HAL_UART_Transmit_IT()
- (+) HAL_UART_Receive_IT()
- (+) HAL_UART_IRQHandler()
- (+) UART_Transmit_IT()
- (+) UART_Receive_IT()
-
- (#) No-Blocking mode API's with DMA are :
- (+) HAL_UART_Transmit_DMA()
- (+) HAL_UART_Receive_DMA()
- (+) HAL_UART_DMAPause()
- (+) HAL_UART_DMAResume()
- (+) HAL_UART_DMAStop()
-
- (#) A set of Transfer Complete Callbacks are provided in No_Blocking mode:
- (+) HAL_UART_TxHalfCpltCallback()
- (+) HAL_UART_TxCpltCallback()
- (+) HAL_UART_RxHalfCpltCallback()
- (+) HAL_UART_RxCpltCallback()
- (+) HAL_UART_ErrorCallback()
-
- -@- In the Half duplex communication, it is forbidden to run the transmit
- and receive process in parallel, the UART state HAL_UART_STATE_BUSY_TX_RX can't be useful.

- ===============================================================================
- ##### How to use this driver #####
- ===============================================================================
- [..]
- The USART HAL driver can be used as follows:
-
- (#) Declare a USART_HandleTypeDef handle structure.
- (#) Initialize the USART low level resources by implement the HAL_USART_MspInit ()API:
- (##) Enable the USARTx interface clock.
- (##) USART pins configuration:
- (+) Enable the clock for the USART GPIOs.
- (+) Configure these USART pins as alternate function pull-up.
- (##) NVIC configuration if you need to use interrupt process (HAL_USART_Transmit_IT(),
- HAL_USART_Receive_IT() and HAL_USART_TransmitReceive_IT() APIs):
- (+) Configure the USARTx interrupt priority.
- (+) Enable the NVIC USART IRQ handle.
- (@) The specific USART interrupts (Transmission complete interrupt,
- RXNE interrupt and Error Interrupts) will be managed using the macros
- __HAL_USART_ENABLE_IT() and __HAL_USART_DISABLE_IT() inside the transmit and receive process.
- (##) DMA Configuration if you need to use DMA process (HAL_USART_Transmit_DMA()
- HAL_USART_Receive_IT() and HAL_USART_TransmitReceive_IT() APIs):
- (+) Declare a DMA handle structure for the Tx/Rx stream.
- (+) Enable the DMAx interface clock.
- (+) Configure the declared DMA handle structure with the required Tx/Rx parameters.
- (+) Configure the DMA Tx/Rx Stream.
- (+) Associate the initilalized DMA handle to the USART DMA Tx/Rx handle.
- (+) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx Stream.
-
- (#) Program the Baud Rate, Word Length, Stop Bit, Parity, Hardware
- flow control and Mode(Receiver/Transmitter) in the husart Init structure.
-
- (#) Initialize the USART registers by calling the HAL_USART_Init() API:
- (+) These API's configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
- by calling the customed HAL_USART_MspInit(&husart) API.

- ##### Initialization and Configuration functions #####
- ===============================================================================
- [..]
- This subsection provides a set of functions allowing to initialize the USART
- in asynchronous and in synchronous modes.
- (+) For the asynchronous mode only these parameters can be configured:
- (++) Baud Rate
- (++) Word Length
- (++) Stop Bit
- (++) Parity: If the parity is enabled, then the MSB bit of the data written
- in the data register is transmitted but is changed by the parity bit.
- Depending on the frame length defined by the M bit (8-bits or 9-bits),
- the possible USART frame formats are as listed in the following table:
- +-------------------------------------------------------------+
- | M0 bit | PCE bit | USART frame |
- |---------------------|---------------------------------------|
- | 0 | 0 | | SB | 8 bit data | STB | |
- |---------|-----------|---------------------------------------|
- | 0 | 1 | | SB | 7 bit data | PB | STB | |
- |---------|-----------|---------------------------------------|
- | 1 | 0 | | SB | 9 bit data | STB | |
- |---------|-----------|---------------------------------------|
- | 1 | 1 | | SB | 8 bit data | PB | STB | |
- +-------------------------------------------------------------+
- (++) USART polarity
- (++) USART phase
- (++) USART LastBit
- (++) Receiver/transmitter modes
-
- [..]
- The HAL_USART_Init() function follows the USART synchronous configuration
- procedure (details for the procedure are available in reference manual (RM0329)).

- This subsection provides a set of functions allowing to manage the USART synchronous
- data transfers.
-
- [..] The USART supports master mode only: it cannot receive or send data related to an input
- clock (SCLK is always an output).
-
- (#) There are two mode of transfer:
- (+) Blocking mode: The communication is performed in polling mode.
- The HAL status of all data processing is returned by the same function
- after finishing transfer.
- (+) No-Blocking mode: The communication is performed using Interrupts
- or DMA, These API's return the HAL status.
- The end of the data processing will be indicated through the
- dedicated USART IRQ when using Interrupt mode or the DMA IRQ when
- using DMA mode.
- The HAL_USART_TxCpltCallback(), HAL_USART_RxCpltCallback() and HAL_USART_TxRxCpltCallback() user callbacks
- will be executed respectivelly at the end of the transmit or Receive process
- The HAL_USART_ErrorCallback()user callback will be executed when a communication error is detected
-
- (#) Blocking mode API's are :
- (+) HAL_USART_Transmit()in simplex mode
- (+) HAL_USART_Receive() in full duplex receive only
- (+) HAL_USART_TransmitReceive() in full duplex mode
-
- (#) Non-Blocking mode API's with Interrupt are :
- (+) HAL_USART_Transmit_IT()in simplex mode
- (+) HAL_USART_Receive_IT() in full duplex receive only
- (+) HAL_USART_TransmitReceive_IT()in full duplex mode
- (+) HAL_USART_IRQHandler()
-
- (#) No-Blocking mode functions with DMA are :
- (+) HAL_USART_Transmit_DMA()in simplex mode
- (+) HAL_USART_Receive_DMA() in full duplex receive only
- (+) HAL_USART_TransmitReceive_DMA() in full duplex mode

- This subsection provides a set of functions allowing to control the USART.
- (+) HAL_USART_GetState() API can be helpful to check in run-time the state of the USART peripheral.
- (+) HAL_USART_GetError() API can be helpful to check in run-time the Error Code of the USART peripheral.
- (+) USART_SetConfig() API is used to set the USART communication parameters.
- (+) USART_CheckIdleState() APi ensures that TEACK and/or REACK bits are set after initialization

- * @brief WWDG HAL module driver.
- * This file provides firmware functions to manage the following
- * functionalities of the Window Watchdog (WWDG) peripheral:
- * + Initialization and de-initialization functions
- * + IO operation functions
- * + Peripheral State functions
- @verbatim
- ==============================================================================
- ##### WWDG specific features #####
- ==============================================================================
- [..]
- Once enabled the WWDG generates a system reset on expiry of a programmed
- time period, unless the program refreshes the counter (downcounter)
- before reaching 0x3F value (i.e. a reset is generated when the counter
- value rolls over from 0x40 to 0x3F).
-
- (+) An MCU reset is also generated if the counter value is refreshed
- before the counter has reached the refresh window value. This
- implies that the counter must be refreshed in a limited window.
- (+) Once enabled the WWDG cannot be disabled except by a system reset.
- (+) WWDGRST flag in RCC_CSR register can be used to inform when a WWDG
- reset occurs.
- (+) The WWDG counter input clock is derived from the APB clock divided
- by a programmable prescaler.
- (+) WWDG counter clock = PCLK1 / Prescaler
- WWDG timeout = (WWDG counter clock) * (counter value)
- (+) Min-max timeout value @32 MHz(PCLK1): ~128.0 us / ~65.54 ms
-
-
- ##### How to use this driver #####
- ==============================================================================
- [..]
- (+) Enable WWDG APB1 clock using __WWDG_CLK_ENABLE().
- (+) Set the WWDG prescaler, refresh window and counter value
- using HAL_WWDG_Init() function.
- (+) Start the WWDG using HAL_WWDG_Start() function.
- When the WWDG is enabled the counter value should be configured to
- a value greater than 0x40 to prevent generating an immediate reset.
- (+) Optionally you can enable the Early Wakeup Interrupt (EWI) which is
- generated when the counter reaches 0x40, and then start the WWDG using
- HAL_WWDG_Start_IT().
- Once enabled, EWI interrupt cannot be disabled except by a system reset.
- (+) Then the application program must refresh the WWDG counter at regular
- intervals during normal operation to prevent an MCU reset, using
- HAL_WWDG_Refresh() function. This operation must occur only when
- the counter is lower than the refresh window value already programmed.
-
- *** WWDG HAL driver macros list ***
- ==================================
- [..]
- Below the list of most used macros in WWDG HAL driver.
-
- (+) __HAL_WWDG_ENABLE: Enable the WWDG peripheral
- (+) __HAL_WWDG_GET_FLAG: Get the selected WWDG's flag status
- (+) __HAL_WWDG_CLEAR_FLAG: Clear the WWDG's pending flags
- (+) __HAL_WWDG_ENABLE_IT: Enables the WWDG early wakeup interrupt

- *
- * - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must
- * be called whenever the core clock is changed
- * during program execution.
- *
- * This file configures the system clock as follows:
- *-----------------------------------------------------------------------------
- * System clock source | 1- PLL_HSE_EXTC | 3- PLL_HSI
- * | (external 8 MHz clock) | (internal 16 MHz)

+ *
+ * - SystemCoreClock variable: Contains the core clock (HCLK), it can be used

+ *
+ * - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must
+ * be called whenever the core clock is changed
+ * during program execution.
+ *
+ * This file configures the system clock as follows:
+ *-----------------------------------------------------------------------------
+ * System clock source | 1- PLL_HSE_EXTC | 3- PLL_HSI
+ * | (external 8 MHz clock) | (internal 16 MHz)
+ * | 2- PLL_HSE_XTAL |

+ * This file provides two functions and one global variable to be called from

+ *
+ * - SystemCoreClock variable: Contains the core clock (HCLK), it can be used

+ *
+ * - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must
+ * be called whenever the core clock is changed
+ * during program execution.
+ *
+ * This file configures the system clock as follows:
+ *-----------------------------------------------------------------------------
+ * System clock source | 1- PLL_HSE_EXTC | 3- PLL_HSI
+ * | (external 8 MHz clock) | (internal 16 MHz)
+ * | 2- PLL_HSE_XTAL |

+ when clock is configured, by HAL_RCC_ClockConfig().

+ time intervals. Care must be taken if HAL_Delay() is called from a
+ peripheral ISR process, the Tick interrupt line must have higher priority
+ (numerically lower) than the peripheral interrupt. Otherwise the caller

+ @verbatim
+ ==============================================================================
+ ##### ADC specific features #####
+ ==============================================================================
+ [..]
+ (#) 12-bit, 10-bit, 8-bit or 6-bit configurable resolution.
+
+ (#) A built-in hardware oversampler allows to improve analog performances
+ while off-loading the related computational burden from the CPU.
+
+ (#) Interrupt generation at the end of conversion and in case of analog
+ watchdog or overrun events.
+
+ (#) Single and continuous conversion modes.
+
+ (#) Scan or discontinuous mode conversion of channel 0 to channel 18.
+
+ (#) Configurable scan direction (Upward from channel 0 to 18 or Backward from
+ channel 18 to channel 0)
+
+ (#) Data alignment with in-built data coherency.
+
+ (#) Channel-wise programmable sampling time.
+
+ (#) External trigger option with configurable polarity.
+
+ (#) DMA request generation during regular channel conversion.
+
+ (#) ADC supply requirements: 2.4 V to 3.6 V at full speed and down to 1.8 V at
+ slower speed.
+
+ (#) ADC input range: VREF- =VIN =VREF+.
+
+ (#) ADC self-calibration.
+
+ (#) ADC is automatically powered off (AutoOff mode) except during the active
+ conversion phase. This dramatically reduces the power consumption of the
+ ADC.
+
+ (#) Wait mode to prevent ADC overrun in applications with low frequency.
+
+
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+
+ (#) Enable the ADC interface
+ As prerequisite, into HAL_ADC_MspInit(), ADC clock must be configured
+ at RCC top level.
+
+ Depending on both possible clock sources: PCLK clock or ADC asynchronous
+ clock.
+ __ADC1_CLK_ENABLE();
+
+
+ (#) ADC pins configuration
+ (++) Enable the clock for the ADC GPIOs using the following function:
+ __GPIOx_CLK_ENABLE();
+ (++) Configure these ADC pins in analog mode using HAL_GPIO_Init();
+
+ (#) Configure the ADC parameters (conversion resolution, oversampler,
+ data alignment, continuous mode,...) using the HAL_ADC_Init() function.
+
+ (#) Activate the ADC peripheral using one of the start functions:
+ HAL_ADC_Start(), HAL_ADC_Start_IT() or HAL_ADC_Start_DMA()
+
+ *** Channels configuration ***
+ ===============================
+ [..]
+ (+) To configure the ADC channels group, use HAL_ADC_ConfigChannel() function.
+ (+) To read the ADC converted values, use the HAL_ADC_GetValue() function.
+
+ *** DMA feature configuration ***
+ =================================
+ [..]
+ (+) To enable the DMA mode, use the HAL_ADC_Start_DMA() function.
+ (+) To enable the generation of DMA requests continuously at the end of
+ the last DMA transfer, set .Init.DMAContinuousRequests to ENABLE and
+ call HAL_ADC_Init() function.

+ ##### COMP Peripheral features #####
+================================================================================
+
+ [..]
+ The STM32L0xx device family integrates 2 analog comparators COMP1 and COMP2:
+ (#) The non inverting input and inverting input can be set to GPIO pins
+ as shown in table1. COMP Inputs below.
+
+ (#) The COMP output is available using HAL_COMP_GetOutputLevel()
+ and can be set on GPIO pins. Refer to table 2. COMP Outputs below.
+
+ (#) The COMP output can be redirected to embedded timers (TIM2, TIM21, TIM22...) and LPTIM
+ Refer to TIM and LPTIM drivers.
+
+ (#) The comparators COMP1 and COMP2 can be combined in window mode and only COMP2 non inverting input can be used as non-inverting input.
+
+ (#) The 2 comparators have interrupt capability with wake-up
+ from Sleep and Stop modes (through the EXTI controller):
+ (++) COMP1 is internally connected to EXTI Line 21
+ (++) COMP2 is internally connected to EXTI Line 22
+
+ From the corresponding IRQ handler, the right interrupt source can be retrieved with the
+ macro __HAL_COMP_EXTI_GET_FLAG(). Possible values are:
+ (++) COMP_EXTI_LINE_COMP1_EVENT
+ (++) COMP_EXTI_LINE_COMP2_EVENT
+
+
+[..] Table 1. COMP Inputs for the STM32L0xx devices

+ |-----------------|----------------|---------------|
+ | | 1/4 VREFINT | -- | OK |

+
+
+ ##### How to use this driver #####
+================================================================================
+ [..]
+ This driver provides functions to configure and program the Comparators of all STM32L0xx devices.
+
+ To use the comparator, perform the following steps:
+
+ (#) Initialize the COMP low level resources by implementing the HAL_COMP_MspInit().
+ (++) Configure the comparator input in analog mode using HAL_GPIO_Init().
+ (++) Configure the comparator output in alternate function mode using HAL_GPIO_Init() to map the comparator
+ output to the GPIO pin.
+ (++) If required enable the VREFINT reference using HAL_VREFINT_Cmd() and HAL_COMP_EnableBuffer_Cmd().
+ (++) If required enable the COMP interrupt by configuring and enabling EXTI line in Interrupt mode and
+ selecting the desired sensitivity level using HAL_GPIO_Init() function. After that enable the comparator
+ interrupt vector using HAL_NVIC_EnableIRQ() function.
+
+ (#) Configure the comparator using HAL_COMP_Init() function:
+ (++) Select the inverting input
+ (++) Select the non-inverting input
+ (++) Select the output polarity
+ (++) Select the power mode
+ (++) Select the window mode
+
+ (#) Enable the comparator using HAL_COMP_Start() function

+ * + Initialization and de-initialization functions
+ * + Peripheral Control functions
+ *
+ @verbatim
+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+
+ [..]
+ *** How to configure Interrupts using CORTEX HAL driver ***
+ ===========================================================
+ [..]
+ This section provide functions allowing to configure the NVIC interrupts (IRQ).
+ The Cortex-M0+ exceptions are managed by CMSIS functions.
+ (#) Enable and Configure the priority of the selected IRQ Channels.
+ The priority can be 0..3.
+
+ -@- Lower priority values gives higher priority.
+ -@- Priority Order:
+ (#@) Lowest priority.
+ (#@) Lowest hardware priority (IRQn position).
+
+ (#) Configure the priority of the selected IRQ Channels using HAL_NVIC_SetPriority()
+
+ (#) Enable the selected IRQ Channels using HAL_NVIC_EnableIRQ()
+
+ [..]
+ *** How to configure Systick using CORTEX HAL driver ***
+ ========================================================
+ [..]
+ Setup SysTick Timer for time base
+
+ (+) The HAL_SYSTICK_Config()function calls the SysTick_Config() function which
+ is a CMSIS function that:
+ (++) Configures the SysTick Reload register with value passed as function parameter.
+ (++) Configures the SysTick IRQ priority to the lowest value (0x03).
+ (++) Resets the SysTick Counter register.
+ (++) Configures the SysTick Counter clock source to be Core Clock Source (HCLK).
+ (++) Enables the SysTick Interrupt.
+ (++) Starts the SysTick Counter.
+
+ (+) You can change the SysTick Clock source to be HCLK_Div8 by calling the macro
+ __HAL_CORTEX_SYSTICKCLK_CONFIG(SYSTICK_CLKSOURCE_HCLK_DIV8) just after the
+ HAL_SYSTICK_Config() function call. The __HAL_CORTEX_SYSTICKCLK_CONFIG() macro is defined
+ inside the stm32l0xx_hal_cortex.h file.
+
+ (+) You can change the SysTick IRQ priority by calling the
+ HAL_NVIC_SetPriority(SysTick_IRQn,...) function just after the HAL_SYSTICK_Config() function
+ call. The HAL_NVIC_SetPriority() call the NVIC_SetPriority() function which is a CMSIS function.
+
+ (+) To adjust the SysTick time base, use the following formula:
+
+ Reload Value = SysTick Counter Clock (Hz) x Desired Time base (s)
+ (++) Reload Value is the parameter to be passed for HAL_SYSTICK_Config() function
+ (++) Reload Value should not exceed 0xFFFFFF

+ * + Initialization and de-initialization functions
+ * + Processing functions by algorithm using polling mode
+ * + Processing functions by algorithm using interrupt mode

+ *
+ @verbatim
+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ The CRYP HAL driver can be used as follows:
+
+ (#)Initialize the CRYP low level resources by implementing the HAL_CRYP_MspInit():
+ (##) Enable the CRYP interface clock using __CRYP_CLK_ENABLE()
+ (##) In case of using interrupts (e.g. HAL_AES_ECB_Encrypt_IT())
+ (+) Configure the CRYP interrupt priority using HAL_NVIC_SetPriority()
+ (+) Enable the CRYP IRQ handler using HAL_NVIC_EnableIRQ()
+ (+) In CRYP IRQ handler, call HAL_CRYP_IRQHandler()
+ (##) In case of using DMA to control data transfer (e.g. HAL_AES_ECB_Encrypt_DMA())
+ (+) Enable the DMA1 interface clock using
+ (++) __DMA1_CLK_ENABLE()
+ (+) Configure and enable two DMA Channels one for managing data transfer from
+ memory to peripheral (input channel) and another channel for managing data
+ transfer from peripheral to memory (output channel)
+ (+) Associate the initilalized DMA handle to the CRYP DMA handle
+ using __HAL_LINKDMA()
+ (+) Configure the priority and enable the NVIC for the transfer complete
+ interrupt on the two DMA Streams. The output stream should have higher
+ priority than the input stream.
+ (++) HAL_NVIC_SetPriority()
+ (++) HAL_NVIC_EnableIRQ()
+
+ (#)Initialize the CRYP HAL using HAL_CRYP_Init(). This function configures mainly:
+ (##) The data type: 1-bit, 8-bit, 16-bit and 32-bit
+ (##) The encryption/decryption key.
+ (##) The initialization vector (counter). It is not used ECB mode.
+
+ (#)Three processing (encryption/decryption) functions are available:
+ (##) Polling mode: encryption and decryption APIs are blocking functions
+ i.e. they process the data and wait till the processing is finished
+ e.g. HAL_CRYP_AESCBC_Encrypt()
+ (##) Interrupt mode: encryption and decryption APIs are not blocking functions
+ i.e. they process the data under interrupt
+ e.g. HAL_CRYP_AESCBC_Encrypt_IT()
+ (##) DMA mode: encryption and decryption APIs are not blocking functions
+ i.e. the data transfer is ensured by DMA
+ e.g. HAL_CRYP_AESCBC_Encrypt_DMA()
+
+ (#)When the processing function is called at first time after HAL_CRYP_Init()
+ the CRYP peripheral is initialized and processes the buffer in input.
+ At second call, the processing function performs an append of the already
+ processed buffer.
+ When a new data block is to be processed, call HAL_CRYP_Init() then the
+ processing function.
+
+ (#)Call HAL_CRYP_DeInit() to deinitialize the CRYP peripheral.

+ * @brief CRYPEx HAL module driver.
+ *
+ * This file provides firmware functions to manage the following
+ * functionalities of the Cryptography (CRYP) extension peripheral:
+ * + Computation completed callback.
+ *
+ @verbatim
+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ The CRYP HAL driver can be used as follows:
+
+ (#)Initialize the CRYP low level resources by implementing the HAL_CRYP_MspInit():
+ (##) Enable the CRYP interface clock using __CRYP_CLK_ENABLE()
+ (##) In case of using interrupts (e.g. HAL_AES_ECB_Encrypt_IT())
+ (+) Configure the CRYP interrupt priority using HAL_NVIC_SetPriority()
+ (+) Enable the CRYP IRQ handler using HAL_NVIC_EnableIRQ()
+ (+) In CRYP IRQ handler, call HAL_CRYP_IRQHandler()
+ (##) In case of using DMA to control data transfer (e.g. HAL_AES_ECB_Encrypt_DMA())
+ (+) Enable the DMA1 interface clock using
+ (++) __DMA1_CLK_ENABLE()
+ (+) Configure and enable two DMA Channels one for managing data transfer from
+ memory to peripheral (input channel) and another channel for managing data
+ transfer from peripheral to memory (output channel)
+ (+) Associate the initilalized DMA handle to the CRYP DMA handle
+ using __HAL_LINKDMA()
+ (+) Configure the priority and enable the NVIC for the transfer complete
+ interrupt on the two DMA Streams. The output stream should have higher
+ priority than the input stream.
+ (++) HAL_NVIC_SetPriority()
+ (++) HAL_NVIC_EnableIRQ()
+
+ (#)Initialize the CRYP HAL using HAL_CRYP_Init(). This function configures mainly:
+ (##) The data type: 1-bit, 8-bit, 16-bit and 32-bit
+ (##) The encryption/decryption key.
+ (##) The initialization vector (counter). It is not used ECB mode.
+
+ (#)Three processing (encryption/decryption) functions are available:
+ (##) Polling mode: encryption and decryption APIs are blocking functions
+ i.e. they process the data and wait till the processing is finished
+ e.g. HAL_CRYP_AESCBC_Encrypt()
+ (##) Interrupt mode: encryption and decryption APIs are not blocking functions
+ i.e. they process the data under interrupt
+ e.g. HAL_CRYP_AESCBC_Encrypt_IT()
+ (##) DMA mode: encryption and decryption APIs are not blocking functions
+ i.e. the data transfer is ensured by DMA
+ e.g. HAL_CRYP_AESCBC_Encrypt_DMA()
+
+ (#)When the processing function is called at first time after HAL_CRYP_Init()
+ the CRYP peripheral is initialized and processes the buffer in input.
+ At second call, the processing function performs an append of the already
+ processed buffer.
+ When a new data block is to be processed, call HAL_CRYP_Init() then the
+ processing function.
+
+ (#)Call HAL_CRYP_DeInit() to deinitialize the CRYP peripheral.

+ * @brief DAC HAL module driver.
+ *
+ * This file provides firmware functions to manage the following
+ * functionalities of the Digital to Analog Converter (DAC) peripheral:
+ * + DAC channels configuration: trigger, output buffer, data format
+ * + DMA management
+ *
+ *
+ @verbatim
+ ==============================================================================
+ ##### DAC Peripheral features #####
+ ==============================================================================
+ [..]
+ *** DAC Channels ***
+ ====================
+ [..]
+ The device integrates 1 12-bit Digital Analog Converters:
+ (#) DAC channel1 with DAC_OUT1 (PA4) as output
+
+ *** DAC Triggers ***
+ ====================
+ [..]
+ Digital to Analog conversion can be non-triggered using DAC_Trigger_None
+ and DAC_OUT1/DAC_OUT2 is available once writing to DHRx register.
+ [..]
+ Digital to Analog conversion can be triggered by:
+ (#) External event: EXTI Line 9 (any GPIOx_Pin9) using DAC_Trigger_Ext_IT9.
+ The used pin (GPIOx_Pin9) must be configured in input mode.
+
+ (#) Timers TRGO: TIM2, TIM6 and TIM21
+ (DAC_Trigger_T2_TRGO, DAC_Trigger_T6_TRGO...)
+
+ (#) Software using DAC_Trigger_Software
+
+ *** DAC Buffer mode feature ***
+ ===============================
+ [..]
+ Each DAC channel integrates an output buffer that can be used to
+ reduce the output impedance, and to drive external loads directly
+ without having to add an external operational amplifier.
+ To enable, the output buffer use
+ sConfig.DAC_OutputBuffer = DAC_OutputBuffer_Enable;
+ [..]
+ (@) Refer to the device datasheet for more details about output
+ impedance value with and without output buffer.
+
+ *** DAC wave generation feature ***
+ ===================================
+ [..]
+ Both DAC channels can be used to generate
+ (#) Noise wave using HAL_DAC_NoiseWaveGenerate()
+ (#) Triangle wave using HAL_DAC_TriangleWaveGenerate()
+
+ *** DAC data format ***
+ =======================
+ [..]
+ The DAC data format can be:
+ (#) 8-bit right alignment using DAC_ALIGN_8B_R
+ (#) 12-bit left alignment using DAC_ALIGN_12B_L
+ (#) 12-bit right alignment using DAC_ALIGN_12B_R
+
+ *** DAC data value to voltage correspondence ***
+ ================================================
+ [..]
+ The analog output voltage on each DAC channel pin is determined
+ by the following equation:
+ DAC_OUTx = VREF+ * DOR / 4095
+ with DOR is the Data Output Register
+ VEF+ is the input voltage reference (refer to the device datasheet)
+ e.g. To set DAC_OUT1 to 0.7V, use
+ Assuming that VREF+ = 3.3V, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V
+
+ *** DMA requests ***
+ =====================
+ [..]
+ A DMA1 request can be generated when an external trigger (but not
+ a software trigger) occurs if DMA1 requests are enabled using
+ HAL_DAC_Start_DMA()
+ [..]
+ DMA1 requests are mapped as following:
+ (#) DAC channel1 : mapped on DMA1 Request9 channel2 which must be
+ already configured
+
+
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ (+) DAC APB clock must be enabled to get write access to DAC
+ registers using HAL_DAC_Init()
+ (+) Configure DAC_OUTx (DAC_OUT1: PA4) in analog mode.
+ (+) Configure the DAC channel using HAL_DAC_ConfigChannel() function.
+ (+) Enable the DAC channel using HAL_DAC_Start() or HAL_DAC_Start_DMA functions

+ * This file provides firmware functions to manage the following

+ * + Initialization/de-initialization functions
+ * + I/O operation functions
+ * + Peripheral State functions
+ *
+ *
+ @verbatim
+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ (#) Enable and configure the peripheral to be connected to the DMA Channel
+ (except for internal SRAM / FLASH memories: no initialization is
+ necessary).
+
+ (#) For a given Channel, program the required configuration through the following parameters:
+ Channel request, Transfer Direction, Source and Destination data formats,
+ Circular, Normal or peripheral flow control mode, Channel Priority level,
+ Source and Destination Increment mode using HAL_DMA_Init() function.
+
+ *** Polling mode IO operation ***
+ =================================
+ [..]
+ (+) Use HAL_DMA_Start() to start DMA transfer after the configuration of Source
+ address and destination address and the Length of data to be transferred
+ (+) Use HAL_DMA_PollForTransfer() to poll for the end of current transfer, in this
+ case a fixed Timeout can be configured by User depending from his application.
+
+ *** Interrupt mode IO operation ***
+ ===================================
+ [..]
+ (+) Configure the DMA interrupt priority using HAL_NVIC_SetPriority()
+ (+) Enable the DMA IRQ handler using HAL_NVIC_EnableIRQ()
+ (+) Use HAL_DMA_Start_IT() to start DMA transfer after the configuration of
+ Source address and destination address and the Length of data to be transferred. In this
+ case the DMA interrupt is configured
+ (+) Use HAL_DMA_IRQHandler() called under DMA_IRQHandler() Interrupt subroutine
+ (+) At the end of data transfer HAL_DMA_IRQHandler() function is executed and user can
+ add his own function by customization of function pointer XferCpltCallback and
+ XferErrorCallback (i.e a member of DMA handle structure).
+
+ (#) Use HAL_DMA_GetState() function to return the DMA state and HAL_DMA_GetError() in case of error
+ detection.
+
+ (#) Use HAL_DMA_Abort() function to abort the current transfer
+
+ -@- In Memory-to-Memory transfer mode, Circular mode is not allowed.

+ * @brief FLASH HAL module driver.
+ * This file provides firmware functions to manage the following
+ * functionalities of the internal FLASH memory:
+ * + FLASH Interface configuration
+ * + FLASH Memory Programming
+ * + DATA EEPROM Programming
+ * + Option Bytes Programming
+ * + Interrupts and flags management
+ *
+ * @verbatim
+
+ ==============================================================================
+ ##### FLASH peripheral features #####
+ ==============================================================================
+
+ [..] The Flash memory interface manages CPU accesses to the Flash memory.
+ It implements the erase and program Flash memory operations
+ and the read and write protection mechanisms.
+
+ [..] The FLASH main features are:
+ (+) Flash memory read operations
+ (+) Flash memory program/erase operations
+ (+) Read / write protections
+ (+) Option Bytes programming
+
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ This driver provides functions and macros to configure and program the FLASH
+ memory of all STM32L0xx devices.
+
+ (#) FLASH Memory IO Programming functions:
+ (++) Lock and Unlock the FLASH interface using HAL_FLASH_Unlock() and
+ HAL_FLASH_Lock() functions
+ (++) Program functions: byte, half word and word
+ (++) There Two modes of programming :
+ (+++) Polling mode using HAL_FLASH_Program() function
+ (+++) Interrupt mode using HAL_FLASH_Program_IT() function
+
+ (#) Interrupts and flags management functions :
+ (++) Handle FLASH interrupts by calling HAL_FLASH_IRQHandler()
+ (++) Wait for last FLASH operation according to its status
+ (++) Get error flag status by calling HAL_GetErrorCode()
+
+ [..]
+ In addition to these functions, this driver includes a set of macros allowing
+ to handle the following operations:
+ (+) Set the latency
+ (+) Enable/Disable the prefetch buffer
+ (+) Enable/Disable the preread buffer
+ (+) Enable/Disable the Flash power-down
+ (+) Enable/Disable the FLASH interrupts
+ (+) Monitor the FLASH flags status
+
+ ===============================================================================
+ ##### Programming operation functions #####
+ ===============================================================================
+ [..]
+ This subsection provides a set of functions allowing to manage the FLASH
+ program operations.
+
+ [..] The FLASH Memory Programming functions, includes the following functions:
+ (+) HAL_FLASH_Unlock(void);
+ (+) HAL_FLASH_Lock(void);
+ (+) HAL_FLASH_Program(uint32_t TypeProgram, uint32_t Address, uint32_t Data)
+ (+) HAL_FLASH_Program_IT(uint32_t TypeProgram, uint32_t Address, uint32_t Data)
+
+ [..] Any operation of erase or program should follow these steps:
+ (#) Call the HAL_FLASH_Unlock() function to enable the flash control register and
+ program memory access.
+ (#) Call the desired function to erase page or program data.
+ (#) Call the HAL_FLASH_Lock() to disable the flash program memory access
+ (recommended to protect the FLASH memory against possible unwanted operation).
+
+ ==============================================================================
+ ##### Option Bytes Programming functions #####
+ ==============================================================================
+
+ [..] The FLASH_Option Bytes Programming_functions, includes the following functions:
+ (+) HAL_FLASH_OB_Unlock(void);
+ (+) HAL_FLASH_OB_Lock(void);
+ (+) HAL_FLASH_OB_Launch(void);
+ (+) HAL_FLASHEx_OBProgram(FLASH_OBProgramInitTypeDef *pOBInit);
+ (+) HAL_FLASHEx_OBGetConfig(FLASH_OBProgramInitTypeDef *pOBInit);
+
+ [..] Any operation of erase or program should follow these steps:
+ (#) Call the HAL_FLASH_OB_Unlock() function to enable the Flash option control
+ register access.
+ (#) Call the following functions to program the desired option bytes.
+ (++) HAL_FLASHEx_OBProgram(FLASH_OBProgramInitTypeDef *pOBInit);
+ (#) Once all needed option bytes to be programmed are correctly written, call the
+ HAL_FLASH_OB_Launch(void) function to launch the Option Bytes programming process.
+ (#) Call the HAL_FLASH_OB_Lock() to disable the Flash option control register access (recommended
+ to protect the option Bytes against possible unwanted operations).
+
+ [..] Proprietary code Read Out Protection (PcROP):
+ (#) The PcROP sector is selected by using the same option bytes as the Write
+ protection (nWRPi bits). As a result, these 2 options are exclusive each other.
+ (#) In order to activate the PcROP (change the function of the nWRPi option bits),
+ the SPRMOD option bit must be activated.
+ (#) The active value of nWRPi bits is inverted when PCROP mode is active, this
+ means: if SPRMOD = 1 and nWRPi = 1 (default value), then the user page "i"
+ is read/write protected.
+ (#) To activate PCROP mode for Flash page(s), you need to follow the sequence below:
+ (++) For page(s) within the first 64KB of the Flash, use this function
+ HAL_FLASHEx_AdvOBProgram with PCROPState = PCROPSTATE_ENABLE.

+ * @brief GPIO HAL module driver.
+ * This file provides firmware functions to manage the following
+ * functionalities of the General Purpose Input/Output (GPIO) peripheral:
+ * + Initialization and de-initialization functions
+ * + IO operation functions
+ *
+ @verbatim
+ ==============================================================================
+ ##### GPIO Peripheral features #####
+ ==============================================================================
+ [..]
+ (+) Each port bit of the general-purpose I/O (GPIO) ports can be individually
+ configured by software in several modes:
+ (++) Input mode
+ (++) Analog mode
+ (++) Output mode
+ (++) Alternate function mode
+ (++) External interrupt/event lines
+
+ (+) During and just after reset, the alternate functions and external interrupt
+ lines are not active and the I/O ports are configured in input floating mode.
+
+ (+) All GPIO pins have weak internal pull-up and pull-down resistors, which can be
+ activated or not.
+
+ (+) In Output or Alternate mode, each IO can be configured on open-drain or push-pull
+ type and the IO speed can be selected depending on the VDD value.
+
+ (+) The microcontroller IO pins are connected to onboard peripherals/modules through a
+ multiplexer that allows only one peripheral alternate function (AF) connected
+ to an IO pin at a time. In this way, there can be no conflict between peripherals
+ sharing the same IO pin.
+
+ (+) All ports have external interrupt/event capability. To use external interrupt
+ lines, the port must be configured in input mode. All available GPIO pins are
+ connected to the 16 external interrupt/event lines from EXTI0 to EXTI15.
+
+ (+) The external interrupt/event controller consists of up to 23 edge detectors
+ (16 lines are connected to GPIO) for generating event/interrupt requests (each
+ input line can be independently configured to select the type (interrupt or event)
+ and the corresponding trigger event (rising or falling or both). Each line can
+ also be masked independently.
+
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ (#) Enable the GPIO IOPORT clock using the following function: __GPIOx_CLK_ENABLE().
+
+ (#) In case of external interrupt/event mode selection, enable the SYSCFG clock
+ using the following function __SYSCFG_CLK_ENABLE().
+
+ (#) Configure the GPIO pin(s) using HAL_GPIO_Init().
+ (++) Configure the IO mode using "Mode" member from GPIO_InitTypeDef structure
+ (++) Activate Pull-up, Pull-down resistor using "Pull" member from GPIO_InitTypeDef
+ structure.
+ (++) In case of Output or alternate function mode selection: the speed is
+ configured through "Speed" member from GPIO_InitTypeDef structure.
+ (++) In alternate mode is selection, the alternate function connected to the IO
+ is configured through "Alternate" member from GPIO_InitTypeDef structure.
+ (++) Analog mode is required when a pin is to be used as ADC channel
+ or DAC output.
+ (++) In case of external interrupt/event selection the "Mode" member from
+ GPIO_InitTypeDef structure select the type (interrupt or event) and
+ the corresponding trigger event (rising or falling or both).
+
+ (#) In case of external interrupt/event mode selection, configure NVIC IRQ priority
+ mapped to the EXTI line using HAL_NVIC_SetPriority() and enable it using
+ HAL_NVIC_EnableIRQ().
+
+ (#) To get the level of a pin configured in input mode use HAL_GPIO_ReadPin().
+
+ (#) To set/reset the level of a pin configured in output mode use
+ HAL_GPIO_WritePin()/HAL_GPIO_TogglePin().
+
+ (#) During and just after reset, the alternate functions are not
+ active and the GPIO pins are configured in input floating mode (except JTAG
+ pins).
+
+ (#) The LSE oscillator pins OSC32_IN and OSC32_OUT can be used as general purpose
+ (PC14 and PC15, respectively) when the LSE oscillator is off. The LSE has
+ priority over the GPIO function.
+
+ (#) The HSE oscillator pins OSC_IN/OSC_OUT can be used as
+ general purpose PH0 and PH1, respectively, when the HSE oscillator is off.
+ The HSE has priority over the GPIO function.

+ @verbatim
+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ The I2C HAL driver can be used as follows:
+
+ (#) Declare a I2C_HandleTypeDef handle structure, for example:
+ I2C_HandleTypeDef hi2c;
+
+ (#)Initialize the I2C low level resources by implement the HAL_I2C_MspInit ()API:
+ (##) Enable the I2Cx interface clock
+ (##) I2C pins configuration
+ (+++) Enable the clock for the I2C GPIOs
+ (+++) Configure I2C pins as alternate function open-drain
+ (##) NVIC configuration if you need to use interrupt process
+ (+++) Configure the I2Cx interrupt priority
+ (+++) Enable the NVIC I2C IRQ Channel
+ (##) DMA Configuration if you need to use DMA process
+ (+++) Declare a DMA_HandleTypeDef handle structure for the transmit or receive stream
+ (+++) Enable the DMAx interface clock using
+ (+++) Configure the DMA handle parameters
+ (+++) Configure the DMA Tx or Rx Stream
+ (+++) Associate the initilalized DMA handle to the hi2c DMA Tx or Rx handle
+ (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx or Rx Stream
+
+ (#) Configure the Communication Clock Timing, Own Address1, Master Adressing Mode, Dual Addressing mode,
+ Own Address2, Own Address2 Mask, General call and Nostretch mode in the hi2c Init structure.
+
+ (#) Initialize the I2C registers by calling the HAL_I2C_Init() API:
+ (+++) These API's configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
+ by calling the customed HAL_I2C_MspInit(&hi2c) API.
+
+ (#) To check if target device is ready for communication, use the function HAL_I2C_IsDeviceReady()
+
+ (#) For I2C IO and IO MEM operations, three mode of operations are available within this driver :

+ * @brief I2S HAL module driver.
+ *
+ * This file provides firmware functions to manage the following
+ * functionalities of the Integrated Interchip Sound (I2S) peripheral:
+ * + Initialization and de-initialization functions
+ * + IO operation functions
+ * + Peripheral State and Errors functions
+ @verbatim
+ ===============================================================================
+ ##### How to use this driver #####
+ ===============================================================================
+ [..]
+ The I2S HAL driver can be used as follow:
+
+ (#) Declare a I2S_HandleTypeDef handle structure.
+ (#) Initialize the I2S low level resources by implement the HAL_I2S_MspInit() API:
+ (##) Enable the SPIx interface clock.
+ (##) I2S pins configuration:
+ (+++) Enable the clock for the I2S GPIOs.
+ (+++) Configure these I2S pins as alternate function pull-up.
+ (##) NVIC configuration if you need to use interrupt process (HAL_I2S_Transmit_IT()
+ and HAL_I2S_Receive_IT() APIs).
+ (+++) Configure the I2Sx interrupt priority.
+ (+++) Enable the NVIC I2S IRQ handle.
+ (##) DMA Configuration if you need to use DMA process (HAL_I2S_Transmit_DMA()
+ and HAL_I2S_Receive_DMA() APIs:
+ (+++) Declare a DMA handle structure for the Tx/Rx stream.
+ (+++) Enable the DMAx interface clock.
+ (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.
+ (+++) Configure the DMA Tx/Rx Stream.
+ (+++) Associate the initilalized DMA handle to the I2S DMA Tx/Rx handle.
+ (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the
+ DMA Tx/Rx Stream.
+
+ (#) Program the Mode, Standard, Data Format, MCLK Output, Audio frequency and Polarity
+ using HAL_I2S_Init() function.
+
+ -@- The specific I2S interrupts (Transmission complete interrupt,
+ RXNE interrupt and Error Interrupts) will be managed using the macros
+ __I2S_ENABLE_IT() and __I2S_DISABLE_IT() inside the transmit and receive process.
+ (#) Three mode of operations are available within this driver :
+
+ *** Polling mode IO operation ***
+ =================================
+ [..]
+ (+) Send an amount of data in blocking mode using HAL_I2S_Transmit()
+ (+) Receive an amount of data in blocking mode using HAL_I2S_Receive()
+
+ *** Interrupt mode IO operation ***
+ ===================================
+ [..]
+ (+) Send an amount of data in non blocking mode using HAL_I2S_Transmit_IT()
+ (+) At transmission end of transfer HAL_I2S_TxCpltCallback is executed and user can
+ add his own code by customization of function pointer HAL_I2S_TxCpltCallback
+ (+) Receive an amount of data in non blocking mode using HAL_I2S_Receive_IT()
+ (+) At reception end of transfer HAL_I2S_RxCpltCallback is executed and user can
+ add his own code by customization of function pointer HAL_I2S_RxCpltCallback
+ (+) In case of transfer Error, HAL_I2S_ErrorCallback() function is executed and user can
+ add his own code by customization of function pointer HAL_I2S_ErrorCallback
+
+ *** DMA mode IO operation ***
+ ==============================
+ [..]
+ (+) Send an amount of data in non blocking mode (DMA) using HAL_I2S_Transmit_DMA()
+ (+) At transmission end of half transfer HAL_I2S_TxHalfCpltCallback is executed and user can
+ add his own code by customization of function pointer HAL_I2S_TxHalfCpltCallback
+ (+) At transmission end of transfer HAL_I2S_TxCpltCallback is executed and user can
+ add his own code by customization of function pointer HAL_I2S_TxCpltCallback
+ (+) Receive an amount of data in non blocking mode (DMA) using HAL_I2S_Receive_DMA()
+ (+) At reception end of half transfer HAL_I2S_RxHalfCpltCallback is executed and user can
+ add his own code by customization of function pointer HAL_I2S_RxHalfCpltCallback
+ (+) At reception end of transfer HAL_I2S_RxCpltCallback is executed and user can
+ add his own code by customization of function pointer HAL_I2S_RxCpltCallback
+ (+) In case of transfer Error, HAL_I2S_ErrorCallback() function is executed and user can
+ add his own code by customization of function pointer HAL_I2S_ErrorCallback
+ (+) Pause the DMA Transfer using HAL_I2S_DMAPause()
+ (+) Resume the DMA Transfer using HAL_I2S_DMAResume()
+ (+) Stop the DMA Transfer using HAL_I2S_DMAStop()
+
+ *** I2S HAL driver macros list ***
+ ===================================
+ [..]
+ Below the list of most used macros in USART HAL driver.
+
+ (+) __HAL_I2S_ENABLE: Enable the specified SPI peripheral (in I2S mode)
+ (+) __HAL_I2S_DISABLE: Disable the specified SPI peripheral (in I2S mode)
+ (+) __HAL_I2S_ENABLE_IT : Enable the specified I2S interrupts
+ (+) __HAL_I2S_DISABLE_IT : Disable the specified I2S interrupts
+ (+) __HAL_I2S_GET_FLAG: Check whether the specified I2S flag is set or not
+
+ [..]
+ (@) You can refer to the I2S HAL driver header file for more useful macros

+ This subsection provides a set of functions allowing to initialize the USARTx
+ in asynchronous IRDA mode.
+ (+) For the asynchronous mode only these parameters can be configured:
+ (++) Baud Rate
+ (++) Word Length
+ (++) Parity: If the parity is enabled, then the MSB bit of the data written
+ in the data register is transmitted but is changed by the parity bit.
+ Depending on the frame length defined by the M bit (8-bits or 9-bits)
+ or by the M1 and M0 bits (7-bit, 8-bit or 9-bit),
+ the possible IRDA frame formats are as listed in the following table:
+ +---------------------------------------------------------------+
+ | M1M0 bits | PCE bit | IRDA frame |
+ |-----------|-----------|---------------------------------------|
+ | 00 | 0 | | SB | 8-bit data | STB | |

+ * @date 18-June-2014
+ * @brief IWDG HAL module driver.
+ * This file provides firmware functions to manage the following
+ * functionalities of the Independent Watchdog (IWDG) peripheral:
+ * + Initialization and de-initialization functions
+ * + IO operation functions
+ * + Peripheral State functions
+ *
+ @verbatim
+ ==============================================================================
+ ##### IWDG Generic features #####
+ ==============================================================================
+ [..]
+ (+) The IWDG can be started by either software or hardware (configurable
+ through option byte).
+
+ (+) The IWDG is clocked by its own dedicated Low-Speed clock (LSI) and
+ thus stays active even if the main clock fails.
+ Once the IWDG is started, the LSI is forced ON and cannot be disabled
+ (LSI cannot be disabled too), and the counter starts counting down from
+ the reset value of 0xFFF. When it reaches the end of count value (0x000)
+ a system reset is generated.
+
+ (+) The IWDG counter should be refreshed at regular intervals, otherwise the
+ watchdog generates an MCU reset when the counter reaches 0.
+
+ (+) The IWDG is implemented in the VDD voltage domain that is still functional
+ in STOP and STANDBY mode (IWDG reset can wake-up from STANDBY).
+ IWDGRST flag in RCC_CSR register can be used to inform when an IWDG
+ reset occurs.
+
+ [..] Min-max timeout value @32KHz (LSI): ~0.512ms / ~32.0s
+ The IWDG timeout may vary due to LSI frequency dispersion. STM32L0xx
+ devices provide the capability to measure the LSI frequency (LSI clock
+ connected internally to TIM5 CH4 input capture). The measured value
+ can be used to have an IWDG timeout with an acceptable accuracy.
+
+
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ If Window option is disabled
+
+ (+) Use IWDG using HAL_IWDG_Init() function to :
+ (++) Enable write access to IWDG_PR, IWDG_RLR.
+ (++) Configure the IWDG prescaler, counter reload value.
+ This reload value will be loaded in the IWDG counter each time the counter
+ is reloaded, then the IWDG will start counting down from this value.
+ (+) Use IWDG using HAL_IWDG_Start() function to :
+ (++) Reload IWDG counter with value defined in the IWDG_RLR register.
+ (++) Start the IWDG, when the IWDG is used in software mode (no need
+ to enable the LSI, it will be enabled by hardware).
+ (+) Then the application program must refresh the IWDG counter at regular
+ intervals during normal operation to prevent an MCU reset, using
+ HAL_IWDG_Refresh() function.
+ [..]
+ if Window option is enabled:
+
+ (+) Use IWDG using HAL_IWDG_Start() function to enable IWDG downcounter
+ (+) Use IWDG using HAL_IWDG_Init() function to :
+ (++) Enable write access to IWDG_PR, IWDG_RLR and IWDG_WINR registers.
+ (++) Configure the IWDG prescaler, reload value and window value.
+ (+) Then the application program must refresh the IWDG counter at regular
+ intervals during normal operation to prevent an MCU reset, using
+ HAL_IWDG_Refresh() function.
+
+ *** IWDG HAL driver macros list ***
+ ====================================
+ [..]
+ Below the list of most used macros in IWDG HAL driver.
+
+ (+) __HAL_IWDG_START: Enable the IWDG peripheral
+ (+) __HAL_IWDG_RELOAD_COUNTER: Reloads IWDG counter with value defined in the reload register
+ (+) __HAL_IWDG_ENABLE_WRITE_ACCESS : Enable write access to IWDG_PR and IWDG_RLR registers
+ (+) __HAL_IWDG_DISABLE_WRITE_ACCESS : Disable write access to IWDG_PR and IWDG_RLR registers
+ (+) __HAL_IWDG_GET_FLAG: Get the selected IWDG's flag status

+ * @brief LCD Controller HAL module driver.
+ * This file provides firmware functions to manage the following
+ * functionalities of the LCD Controller (LCD) peripheral:
+ * + Initialization/de-initialization methods
+ * + I/O operation methods
+ * + Peripheral State methods
+ *
+ @verbatim
+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..] The LCD HAL driver can be used as follows:
+
+ (#) Declare a LCD_HandleTypeDef handle structure.
+
+ (#) Initialize the LCD low level resources by implement the HAL_LCD_MspInit() API:
+ (##) Enable the LCDCLK (same as RTCCLK): to configure the RTCCLK/LCDCLK, proceed as follows:
+ (+) Enable the Power Controller (PWR) APB1 interface clock using the
+ __PWR_CLK_ENABLE() macro.
+ (+) Enable access to RTC domain using the HAL_PWR_EnableBkUpAccess() function.
+ (+) Select the RTC clock source using the __HAL_RCC_RTC_CONFIG() function.
+
+ -@- The frequency generator allows you to achieve various LCD frame rates
+ starting from an LCD input clock frequency (LCDCLK) which can vary
+ from 32 kHz up to 1 MHz.
+ (##) LCD pins configuration:
+ (+) Enable the clock for the LCD GPIOs.
+ (+) Configure these LCD pins as alternate function no-pull.
+ (##) Enable the LCD interface clock.
+
+ (#) Program the Prescaler, Divider, Blink mode, Blink Frequency Duty, Bias,
+ Voltage Source, Dead Time, Pulse On Duration and Contrast in the hlcd Init structure.
+
+ (#) Initialize the LCD registers by calling the HAL_LCD_Init() API.
+
+ -@- The HAL_LCD_Init() API configures also the low level Hardware GPIO, CLOCK, ...etc)
+ by calling the custumed HAL_LCD_MspInit() API.
+ -@- After calling the HAL_LCD_Init() the LCD RAM memory is cleared
+
+ (#) Optionally you can update the LCD configuration using these macros:
+ (+) LCD High Drive using the __HAL_LCD_HIGHDRIVER_ENABLE() and __HAL_LCD_HIGHDRIVER_DISABLE() macros
+ (+) LCD Pulse ON Duration using the __HAL_LCD_PULSEONDURATION_CONFIG() macro
+ (+) LCD Dead Time using the __HAL_LCD_DEADTIME_CONFIG() macro
+ (+) The LCD Blink mode and frequency using the __HAL_LCD_BLINK_CONFIG() macro
+ (+) The LCD Contrast using the __HAL_LCD_CONTRAST_CONFIG() macro
+
+ (#) Write to the LCD RAM memory using the HAL_LCD_Write() API, this API can be called
+ more time to update the different LCD RAM registers before calling
+ HAL_LCD_UpdateDisplayRequest() API.
+
+ (#) The HAL_LCD_Clear() API can be used to clear the LCD RAM memory.
+
+ (#) When LCD RAM memory is updated enable the update display request using
+ the HAL_LCD_UpdateDisplayRequest() API.
+
+ [..] LCD and low power modes:
+ (#) The LCD remain active during STOP mode.

+ ##### IO operation functions #####
+ ===============================================================================
+ [..] Using its double buffer memory the LCD controller ensures the coherency of the
+ displayed information without having to use interrupts to control LCD_RAM
+ modification.
+ The application software can access the first buffer level (LCD_RAM) through
+ the APB interface. Once it has modified the LCD_RAM using the HAL_LCD_Write() API,
+ it sets the UDR flag in the LCD_SR register using the HAL_LCD_UpdateDisplayRequest() API.
+ This UDR flag (update display request) requests the updated information to be
+ moved into the second buffer level (LCD_DISPLAY).
+ This operation is done synchronously with the frame (at the beginning of the
+ next frame), until the update is completed, the LCD_RAM is write protected and
+ the UDR flag stays high.
+ Once the update is completed another flag (UDD - Update Display Done) is set and
+ generates an interrupt if the UDDIE bit in the LCD_FCR register is set.
+ The time it takes to update LCD_DISPLAY is, in the worst case, one odd and one
+ even frame.
+ The update will not occur (UDR = 1 and UDD = 0) until the display is
+ enabled (LCDEN = 1).

+ *
+ * This file provides firmware functions to manage the following
+ * functionalities of the Low Power Timer (LPTIM) peripheral:
+ * + Initialization and de-initialization functions.
+ * + Start/Stop operation functions in polling mode.
+ * + Start/Stop operation functions in interrupt mode.

+ @verbatim
+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ The LPTIM HAL driver can be used as follows:
+
+ (#)Initialize the LPTIM low level resources by implementing the
+ HAL_LPTIM_MspInit():
+ (##) Enable the LPTIM interface clock using __LPTIM1_CLK_ENABLE().
+ (##) In case of using interrupts (e.g. HAL_LPTIM_PWM_Start_IT()):
+ (+) Configure the LPTIM interrupt priority using HAL_NVIC_SetPriority().
+ (+) Enable the LPTIM IRQ handler using HAL_NVIC_EnableIRQ().
+ (+) In LPTIM IRQ handler, call HAL_LPTIM_IRQHandler().
+
+ (#)Initialize the LPTIM HAL using HAL_LPTIM_Init(). This function
+ configures mainly:
+ (##) The instance: Only LPTIM1 is present in STM32L053xx.
+ (##) Clock: the counter clock.
+ - Source : it can be either the ULPTIM input (IN1) or one of
+ the internal clock; (APB, LSE, LSI or MSI).
+ - Prescaler: select the clock divider.
+ (##) UltraLowPowerClock : To be used only if the ULPTIM is selected
+ as counter clock source.
+ - Polarity: polarity of the active edge for the counter unit
+ if the ULPTIM input is selected.
+ - SampleTime: clock sampling time to configure the clock glitch
+ filter.
+ (##) Trigger: How the counter start.
+ - Source: trigger can be software or one of the hardware triggers.
+ - ActiveEdge : only for hardware trigger.
+ - SampleTime : trigger sampling time to configure the trigger
+ glitch filter.
+ (##) OutputPolarity : 2 opposite polarities are possibles.
+ (##) UpdateMode: specifies whether the update of the autoreload and
+ the compare values is done immediately or after the end of current
+ period.
+
+ (#)Six modes are available:
+
+ (##) PWM Mode: To generate a PWM signal with specified period and pulse,
+ call HAL_LPTIM_PWM_Start() or HAL_LPTIM_PWM_Start_IT() for interruption
+ mode.
+
+ (##) One Pulse Mode: To generate pulse with specified width in response
+ to a stimulus, call HAL_LPTIM_OnePulse_Start() or
+ HAL_LPTIM_OnePulse_Start_IT() for interruption mode.
+
+ (##) Set once Mode: In this mode, the output changes the level (from
+ low level to high level if the output polarity is configured high, else
+ the opposite) when a compare match occurs. To start this mode, call
+ HAL_LPTIM_SetOnce_Start() or HAL_LPTIM_SetOnce_Start_IT() for
+ interruption mode.
+
+ (##) Encoder Mode: To use the encoder interface call
+ HAL_LPTIM_Encoder_Start() or HAL_LPTIM_Encoder_Start_IT() for
+ interruption mode.
+
+ (##) Time out Mode: an active edge on one selected trigger input rests
+ the counter. The first trigger event will start the timer, any
+ successive trigger event will reset the counter and the timer will
+ restart. To start this mode call HAL_LPTIM_TimeOut_Start_IT() or
+ HAL_LPTIM_TimeOut_Start_IT() for interruption mode.
+
+ (##) Counter Mode: counter can be used to count external events on
+ the LPTIM Input1 or it can be used to count internal clock cycles.
+ To start this mode, call HAL_LPTIM_Counter_Start() or
+ HAL_LPTIM_Counter_Start_IT() for interruption mode.
+
+
+ (#) User can stop any process by calling the corresponding API:
+ HAL_LPTIM_Xxx_Stop() or HAL_LPTIM_Xxx_Stop_IT() if the process is
+ already started in interruption mode.
+
+ (#)Call HAL_LPTIM_DeInit() to deinitialize the LPTIM peripheral.

+ * @brief PCD HAL module driver.
+ * This file provides firmware functions to manage the following
+ * functionalities of the USB Peripheral Controller:
+ * + Initialization and de-initialization functions
+ * + IO operation functions
+ * + Peripheral Control functions
+ * + Peripheral State functions
+ *
+ @verbatim
+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ The PCD HAL driver can be used as follows:
+
+ (#) Declare a PCD_HandleTypeDef handle structure, for example:
+ PCD_HandleTypeDef hpcd;
+
+ (#) Fill parameters of Init structure in HCD handle
+
+ (#) Call HAL_PCD_Init() API to initialize the HCD peripheral (Core, Device core, ...)
+
+ (#) Initialize the PCD low level resources through the HAL_PCD_MspInit() API:
+ (##) Enable the PCD/USB Low Level interface clock using
+ (+++) __USB_CLK_ENABLE;
+
+ (##) Initialize the related GPIO clocks
+ (##) Configure PCD pin-out
+ (##) Configure PCD NVIC interrupt
+
+ (#)Associate the Upper USB device stack to the HAL PCD Driver:
+ (##) hpcd.pData = pdev;
+
+ (#)Enable HCD transmission and reception:
+ (##) HAL_PCD_Start();
+
+ @endverbatim

+ ===============================================================================
+ ##### Peripheral Control functions #####
+ ===============================================================================
+
+ *** PVD configuration ***
+ =========================
+ [..]
+ (+) The PVD is used to monitor the VDD power supply by comparing it to a
+ threshold selected by the PVD Level (PLS[2:0] bits in the PWR_CR).
+ (+) The PVD can use an external input analog voltage (PVD_IN) which is compared
+ internally to VREFINT. The PVD_IN (PB7) has to be configured in Analog mode
+ when PWR_PVDLevel_7 is selected (PLS[2:0] = 111).
+
+ (+) A PVDO flag is available to indicate if VDD/VDDA is higher or lower
+ than the PVD threshold. This event is internally connected to the EXTI
+ line16 and can generate an interrupt if enabled. This is done through
+ __HAL_PVD_EXTI_ENABLE_IT() macro.
+ (+) The PVD is stopped in Standby mode.
+
+ *** WakeUp pin configuration ***
+ ================================
+ [..]
+ (+) WakeUp pin is used to wake up the system from Standby mode. This pin is
+ forced in input pull-down configuration and is active on rising edges.
+ (+) There are two WakeUp pins:
+ WakeUp Pin 1 on PA.00.
+ WakeUp Pin 2 on PC.13.
+
+ [..]
+ *** Main and Backup Regulators configuration ***
+ ================================================
+
+ (+) The main internal regulator can be configured to have a tradeoff between
+ performance and power consumption when the device does not operate at
+ the maximum frequency. This is done through __HAL_PWR_VOLTAGESCALING_CONFIG()
+ macro which configure VOS bit in PWR_CR register:
+ (++) When this bit is set (Regulator voltage output Scale 1 mode selected)
+ the System frequency can go up to 32 MHz.
+ (++) When this bit is reset (Regulator voltage output Scale 2 mode selected)
+ the System frequency can go up to 16 MHz.
+ (++) When this bit is reset (Regulator voltage output Scale 3 mode selected)
+ the System frequency can go up to 4.2 MHz.
+
+ Refer to the datasheets for more details.
+
+ *** Low Power modes configuration ***
+ =====================================
+ [..]
+ The device features 5 low-power modes:
+ (+) Low power run mode: regulator in low power mode, limited clock frequency,
+ limited number of peripherals running.
+ (+) Sleep mode: Cortex-M0+ core stopped, peripherals kept running.
+ (+) Low power sleep mode: Cortex-M0+ core stopped, limited clock frequency,
+ limited number of peripherals running, regulator in low power mode.
+ (+) Stop mode: All clocks are stopped, regulator running, regulator in low power mode.
+ (+) Standby mode: VCORE domain powered off
+
+ *** Low power run mode ***
+ =========================
+ [..]
+ To further reduce the consumption when the system is in Run mode, the regulator can be
+ configured in low power mode. In this mode, the system frequency should not exceed
+ MSI frequency range1.
+ In Low power run mode, all I/O pins keep the same state as in Run mode.
+
+ (+) Entry:
+ (++) VCORE in range2
+ (++) Decrease the system frequency tonot exceed the frequency of MSI frequency range1.
+ (++) The regulator is forced in low power mode using the HAL_PWREx_EnableLowPowerRunMode()
+ function.
+ (+) Exit:
+ (++) The regulator is forced in Main regulator mode using the HAL_PWREx_DisableLowPowerRunMode()
+ function.
+ (++) Increase the system frequency if needed.
+
+ *** Sleep mode ***
+ ==================
+ [..]
+ (+) Entry:
+ The Sleep mode is entered by using the HAL_PWR_EnterSLEEPMode(PWR_MAINREGULATOR_ON, PWR_SLEEPENTRY_WFx)
+ functions with
+ (++) PWR_SLEEPENTRY_WFI: enter SLEEP mode with WFI instruction
+ (++) PWR_SLEEPENTRY_WFE: enter SLEEP mode with WFE instruction
+
+ (+) Exit:
+ (++) Any peripheral interrupt acknowledged by the nested vectored interrupt
+ controller (NVIC) can wake up the device from Sleep mode.
+
+ *** Low power sleep mode ***
+ ============================
+ [..]
+ (+) Entry:
+ The Low power sleep mode is entered by using the HAL_PWR_EnterSLEEPMode(PWR_LOWPOWERREGULATOR_ON, PWR_SLEEPENTRY_WFx)
+ functions with
+ (++) PWR_SLEEPENTRY_WFI: enter SLEEP mode with WFI instruction
+ (++) PWR_SLEEPENTRY_WFE: enter SLEEP mode with WFE instruction
+ (+) The Flash memory can be switched off by using the control bits (SLEEP_PD in the FLASH_ACR register.
+ This reduces power consumption but increases the wake-up time.
+
+ (+) Exit:
+ (++) If the WFI instruction was used to enter Low power sleep mode, any peripheral interrupt
+ acknowledged by the nested vectored interrupt controller (NVIC) can wake up the device
+ from Low power sleep mode. If the WFE instruction was used to enter Low power sleep mode,
+ the MCU exits Sleep mode as soon as an event occurs.
+
+ *** Stop mode ***
+ =================
+ [..]
+ The Stop mode is based on the Cortex-M0+ deepsleep mode combined with peripheral
+ clock gating. The voltage regulator can be configured either in normal or low-power mode.
+ In Stop mode, all clocks in the VCORE domain are stopped, the PLL, the MSI, the HSI and
+ the HSE RC oscillators are disabled. Internal SRAM and register contents are preserved.
+ To get the lowest consumption in Stop mode, the internal Flash memory also enters low
+ power mode. When the Flash memory is in power-down mode, an additional startup delay is
+ incurred when waking up from Stop mode.
+ To minimize the consumption In Stop mode, VREFINT, the BOR, PVD, and temperature
+ sensor can be switched off before entering Stop mode. They can be switched on again by
+ software after exiting Stop mode using the ULP bit in the PWR_CR register.
+ In Stop mode, all I/O pins keep the same state as in Run mode.
+
+ (+) Entry:
+ The Stop mode is entered using the HAL_PWR_EnterSTOPMode(PWR_MAINREGULATOR_ON, PWR_SLEEPENTRY_WFI )
+ function with:
+ (++) Main regulator ON.
+ (++) Low Power regulator ON.
+ (++) PWR_SLEEPENTRY_WFI: enter SLEEP mode with WFI instruction
+ (++) PWR_SLEEPENTRY_WFE: enter SLEEP mode with WFE instruction
+ (+) Exit:
+ (++) By issuing an interrupt or a wakeup event, the MSI or HSI16 RC
+ oscillator is selected as system clock depending the bit STOPWUCK in the RCC_CFGR
+ register
+
+ *** Standby mode ***
+ ====================
+ [..]
+ The Standby mode allows to achieve the lowest power consumption. It is based on the
+ Cortex-M0+ deepsleep mode, with the voltage regulator disabled. The VCORE domain is
+ consequently powered off. The PLL, the MSI, the HSI oscillator and the HSE oscillator are
+ also switched off. SRAM and register contents are lost except for the RTC registers, RTC
+ backup registers and Standby circuitry.
+
+ To minimize the consumption In Standby mode, VREFINT, the BOR, PVD, and temperature
+ sensor can be switched off before entering the Standby mode. They can be switched
+ on again by software after exiting the Standby mode.
+ function.
+
+ (+) Entry:
+ (++) The Standby mode is entered using the HAL_PWR_EnterSTANDBYMode() function.
+ (+) Exit:
+ (++) WKUP pin rising edge, RTC alarm (Alarm A and Alarm B), RTC wakeup,
+ tamper event, time-stamp event, external reset in NRST pin, IWDG reset.
+
+ *** Auto-wakeup (AWU) from low-power mode ***
+ =============================================
+ [..]
+ The MCU can be woken up from low-power mode by an RTC Alarm event, an RTC
+ Wakeup event, a tamper event, a time-stamp event, or a comparator event,
+ without depending on an external interrupt (Auto-wakeup mode).
+
+ (+) RTC auto-wakeup (AWU) from the Stop mode
+ (++) To wake up from the Stop mode with an RTC alarm event, it is necessary to:
+ (+++) Configure the EXTI Line 17 to be sensitive to rising edges (Interrupt
+ or Event modes) using the EXTI_Init() function.
+ (+++) Enable the RTC Alarm Interrupt using the RTC_ITConfig() function
+ (+++) Configure the RTC to generate the RTC alarm using the RTC_SetAlarm()
+ and RTC_AlarmCmd() functions.
+ (++) To wake up from the Stop mode with an RTC Tamper or time stamp event, it
+ is necessary to:
+ (+++) Configure the EXTI Line 19 to be sensitive to rising edges (Interrupt
+ or Event modes) using the EXTI_Init() function.
+ (+++) Enable the RTC Tamper or time stamp Interrupt using the RTC_ITConfig()
+ function.
+ (+++) Configure the RTC to detect the tamper or time stamp event using the
+ RTC_TimeStampConfig(), RTC_TamperTriggerConfig() and RTC_TamperCmd()
+ functions.
+ (++) To wake up from the Stop mode with an RTC WakeUp event, it is necessary to:
+ (+++) Configure the EXTI Line 20 to be sensitive to rising edges (Interrupt
+ or Event modes) using the EXTI_Init() function.
+ (+++) Enable the RTC WakeUp Interrupt using the RTC_ITConfig() function.
+ (+++) Configure the RTC to generate the RTC WakeUp event using the RTC_WakeUpClockConfig(),
+ RTC_SetWakeUpCounter() and RTC_WakeUpCmd() functions.
+
+ (+) RTC auto-wakeup (AWU) from the Standby mode
+ (++) To wake up from the Standby mode with an RTC alarm event, it is necessary to:
+ (+++) Enable the RTC Alarm Interrupt using the RTC_ITConfig() function.
+ (+++) Configure the RTC to generate the RTC alarm using the RTC_SetAlarm()
+ and RTC_AlarmCmd() functions.
+ (++) To wake up from the Standby mode with an RTC Tamper or time stamp event, it
+ is necessary to:
+ (+++) Enable the RTC Tamper or time stamp Interrupt using the RTC_ITConfig()
+ function.
+ (+++) Configure the RTC to detect the tamper or time stamp event using the
+ RTC_TimeStampConfig(), RTC_TamperTriggerConfig() and RTC_TamperCmd()
+ functions.
+ (++) To wake up from the Standby mode with an RTC WakeUp event, it is necessary to:
+ (+++) Enable the RTC WakeUp Interrupt using the RTC_ITConfig() function
+ (+++) Configure the RTC to generate the RTC WakeUp event using the RTC_WakeUpClockConfig(),
+ RTC_SetWakeUpCounter() and RTC_WakeUpCmd() functions.
+
+ (+) Comparator auto-wakeup (AWU) from the Stop mode
+ (++) To wake up from the Stop mode with an comparator 1 or comparator 2 wakeup
+ event, it is necessary to:
+ (+++) Configure the EXTI Line 21 for comparator 1 or EXTI Line 22 for comparator 2
+ to be sensitive to to the selected edges (falling, rising or falling
+ and rising) (Interrupt or Event modes) using the EXTI_Init() function.
+ (+++) Configure the comparator to generate the event.

+ @verbatim
+ ==============================================================================
+ ##### RCC specific features #####
+ ==============================================================================
+ [..] After reset the device is running from MSI (2 MHz) with Flash 0 WS,
+ all peripherals are off except internal SRAM, Flash and SW-DP.
+ (+) There is no prescaler on High speed (AHB) and Low speed (APB) busses;
+ all peripherals mapped on these busses are running at MSI speed.
+ (+) The clock for all peripherals is switched off, except the SRAM and
+ FLASH.
+ (+) All GPIOs are in input floating state, except the SW-DP pins which
+ are assigned to be used for debug purpose.
+ [..] Once the device started from reset, the user application has to:
+ (+) Configure the clock source to be used to drive the System clock
+ (if the application needs higher frequency/performance)
+ (+) Configure the System clock frequency and Flash settings
+ (+) Configure the AHB and APB busses prescalers
+ (+) Enable the clock for the peripheral(s) to be used
+ (+) Configure the clock source(s) for peripherals whose clocks are not
+ derived from the System clock (ADC, RTC/LCD, RNG and IWDG)

+ ##### Initialization and de-initialization functions #####
+ ===============================================================================
+ [..]
+ This section provide functions allowing to configure the internal/external
+ clocks, PLL, CSS and MCO.
+ [..] Internal/external clock and PLL configuration
+ (#) HSI (high-speed internal), 16 MHz factory-trimmed RC used directly
+ or through the PLL as System clock source.
+ (#) MSI (multi-speed internal), multispeed low power RC
+ (65.536 KHz to 4.194 MHz) MHz used as System clock source.
+ (#) LSI (low-speed internal), 37 KHz low consumption RC used as IWDG
+ and/or RTC clock source.
+ (#) HSE (high-speed external), 1 to 24 MHz crystal oscillator used
+ directly or through the PLL as System clock source. Can be used
+ also as RTC clock source.
+ (#) LSE (low-speed external), 32 KHz oscillator used as RTC clock source.
+ (#) PLL (clocked by HSI or HSE), for System clock and USB (48 MHz).
+ (#) CSS (Clock security system), once enable and if a HSE clock failure
+ occurs (HSE used directly or through PLL as System clock source),
+ the System clock is automatically switched to MSI and an interrupt
+ is generated if enabled.
+ The interrupt is linked to the Cortex-M3 NMI (Non-Maskable Interrupt)
+ exception vector.
+ (#) MCO (microcontroller clock output), used to output SYSCLK, HSI, MSI,
+ HSE, PLL, LSI or LSE clock (through a configurable prescaler) on
+ PA8 pin.
+ [..] System, AHB and APB busses clocks configuration
+ (#) Several clock sources can be used to drive the System clock (SYSCLK): MSI, HSI,
+ HSE and PLL.
+ The AHB clock (HCLK) is derived from System clock through configurable
+ prescaler and used to clock the CPU, memory and peripherals mapped
+ on IOPORT, AHB bus (DMA,Flash...). APB1 (PCLK1) and APB2 (PCLK2) clocks are derived
+ from AHB clock through configurable prescalers and used to clock
+ the peripherals mapped on these busses. You can use
+ "HAL_RCC_GetSysClockFreq()" function to retrieve the frequencies of these clocks.
+
+ -@- All the peripheral clocks are derived from the System clock (SYSCLK) except:
+ (+@) I2S: the I2S clock can be derived from an external clock mapped on the I2S_CKIN pin.
+
+ (+@) RTC: the RTC clock can be derived either from the LSI, LSE or HSE clock
+ divided by 2 to 16. You have to use __HAL_RCC_RTC_CONFIG() and __HAL_RCC_RTC_ENABLE()
+ macros to configure this clock.
+ (+@) USB FS,and RNG require a frequency equal to 48 MHz to work correctly
+ This clock is derived from the main PLL or HSI48 RC oscillator.
+ (+@) IWDG clock which is always the LSI clock.
+
+ (#) For the STM32L0xx devices, the maximum
+ frequency of the SYSCLK ,HCLK, APB1 and APB2 is 32 MHz.
+ Depending on the device voltage range, the maximum frequency should
+ be adapted accordingly:
+ ----------------------------------------------------------------
+ | Wait states | HCLK clock frequency (MHz) |
+ | |------------------------------------------------|
+ | (Latency) | voltage range | voltage range |
+ | | 1.65 V - 3.6 V | 2.0 V - 3.6 V |
+ | |----------------|---------------|---------------|
+ | | VCORE = 1.2 V | VCORE = 1.5 V | VCORE = 1.8 V |
+ |-------------- |----------------|---------------|---------------|
+ |0WS(1CPU cycle)|0 < HCLK <= 2 |0 < HCLK <= 8 |0 < HCLK <= 16 |
+ |---------------|----------------|---------------|---------------|
+ |1WS(2CPU cycle)|2 < HCLK <= 4 |8 < HCLK <= 16 |16 < HCLK <= 32|
+ ----------------------------------------------------------------

+ * @author MCD Application Team
+ * @version V1.1.0
+ * @date 18-June-2014
+ * @brief Extended RCC HAL module driver.
+ *
+ * This file provides firmware functions to manage the following
+ * functionalities RCC extension peripheral:
+ * + Extended Peripheral Control functions
+ *
+ @verbatim
+ ==============================================================================
+ ##### RCC specific features #####
+ ==============================================================================
+ For CRS, RCC Extension HAL driver can be used as follows:
+
+ (#) In System clock configuration, HSI48 need to be enabled
+
+ (#] Enable CRS clock in IP MSP init which will use CRS functions
+
+ (#) Call CRS functions like this
+ (##) Prepare synchronization configuration necessary for HSI48 calibration
+ (+++) Default values can be set for frequency Error Measurement (reload and error limit)
+ and also HSI48 oscillator smooth trimming.
+ (+++) Macro __HAL_RCC_CRS_CALCULATE_RELOADVALUE can be also used to calculate
+ directly reload value with target and synchronization frequencies values
+ (##) Call function HAL_RCCEx_CRSConfig which
+ (+++) Reset CRS registers to their default values.
+ (+++) Configure CRS registers with synchronization configuration
+ (+++) Enable automatic calibration and frequency error counter feature
+
+ (##) A polling function is provided to wait for complete Synchronization
+ (+++) Call function 'HAL_RCCEx_CRSWaitSynchronization()'
+ (+++) According to CRS status, user can decide to adjust again the calibration or continue
+ application if synchronization is OK
+
+ (#) User can retrieve information related to synchronization in calling function
+ HAL_RCCEx_CRSGetSynchronizationInfo()
+
+ (#) Regarding synchronization status and synchronization information, user can try a new calibration
+ in changing synchronization configuration and call again HAL_RCCEx_CRSConfig.
+ Note: When the SYNC event is detected during the downcounting phase (before reaching the zero value),
+ it means that the actual frequency is lower than the target (and so, that the TRIM value should be
+ incremented), while when it is detected during the upcounting phase it means that the actual frequency
+ is higher (and that the TRIM value should be decremented).
+
+ (#) To use IT mode, user needs to handle it in calling different macros available to do it
+ (__HAL_RCC_CRS_XXX_IT). Interruptions will go through RCC Handler (RCC_IRQn/RCC_CRS_IRQHandler)
+ (+++) Call function HAL_RCCEx_CRSConfig()
+ (+++) Enable RCC_IRQn (thnaks to NVIC functions)
+ (+++) Enable CRS IT (__HAL_RCC_CRS_ENABLE_IT)
+ [+++) Implement CRS status management in RCC_CRS_IRQHandler
+
+ (#) To force a SYNC EVENT, user can use function 'HAL_RCCEx_CRSSoftwareSynchronizationGenerate()'. Function can be
+ called before calling HAL_RCCEx_CRSConfig (for instance in Systick handler)

+ * This file provides firmware functions to manage the following
+ * functionalities of the Real Time Clock (RTC) peripheral:
+ * + Initialization/de-initialization functions
+ * + I/O operation functions
+ * + Peripheral Control functions
+ * + Peripheral State functions
+ *
+ @verbatim
+ ==============================================================================
+ ##### Backup Domain Operating Condition #####
+ ==============================================================================
+ [..] As long as the supply voltage remains in the operating range,
+ the RTC never stops, regardless of the device status (Run mode,
+ low power modes or under reset).
+
+ ##### Backup Domain Reset #####
+ ==================================================================
+ [..] The backup domain reset sets all RTC registers and the RCC_CSR register
+ to their reset values.
+ [..] A backup domain reset is generated when one of the following events occurs:
+ (+) Software reset, triggered by setting the RTCRST bit in the
+ RCC Control Status register (RCC_CSR).
+ (+) Power reset (BOR/POR/PDR).
+
+ ##### Backup Domain Access #####
+ ==================================================================
+ [..] After reset, the backup domain (RTC registers and RTC backup data registers)
+ is protected against possible unwanted write accesses.
+ [..] To enable access to the RTC Domain and RTC registers, proceed as follows:
+ (+) Enable the Power Controller (PWR) APB1 interface clock using the
+ __PWR_CLK_ENABLE() function.
+ (+) Enable access to RTC domain using the HAL_PWR_EnableBkUpAccess() function.
+ (+) Select the RTC clock source using the __HAL_RCC_RTC_CONFIG() function.
+ (+) Enable RTC Clock using the __HAL_RCC_RTC_ENABLE() function.
+
+
+ ##### How to use this driver #####
+ ==================================================================
+ [..]
+ (+) Enable the RTC domain access (see description in the section above).
+ (+) Configure the RTC Prescaler (Asynchronous and Synchronous) and RTC hour
+ format using the HAL_RTC_Init() function.
+
+ *** Time and Date configuration ***
+ ===================================
+ [..]
+ (+) To configure the RTC Calendar (Time and Date) use the HAL_RTC_SetTime()
+ and HAL_RTC_SetDate() functions.
+ (+) To read the RTC Calendar, use the HAL_RTC_GetTime() and HAL_RTC_GetDate() functions.
+
+ *** Alarm configuration ***
+ ===========================
+ [..]
+ (+) To configure the RTC Alarm use the HAL_RTC_SetAlarm() function.
+ You can also configure the RTC Alarm with interrupt mode using the HAL_RTC_SetAlarm_IT() function.
+ (+) To read the RTC Alarm, use the HAL_RTC_GetAlarm() function.
+
+ *** RTC Wakeup configuration ***
+ ================================
+ [..]
+ (+) To configure the RTC Wakeup Clock source and Counter use the HAL_RTC_SetWakeUpTimer()
+ function. You can also configure the RTC Wakeup timer with interrupt mode
+ using the HAL_RTC_SetWakeUpTimer_IT() function.
+ (+) To read the RTC WakeUp Counter register, use the HAL_RTC_GetWakeUpTimer()
+ function.
+
+ *** Outputs configuration ***
+ =============================
+ [..] The RTC has 2 different outputs:
+ (+) RTC_ALARM: this output is used to manage the RTC Alarm A, Alarm B
+ and WaKeUp signals.
+ To output the selected RTC signal, use the HAL_RTC_Init() function.
+ (+) RTC_CALIB: this output is 512Hz signal or 1Hz.
+ To enable the RTC_CALIB, use the HAL_RTCEx_SetCalibrationOutPut() function.
+ (+) Two pins can be used as RTC_ALARM or RTC_CALIB (PC13, PB14) managed on
+ the RTC_OR register.
+ (+) When the RTC_CALIB or RTC_ALARM output is selected, the RTC_OUT pin is
+ automatically configured in output alternate function.
+
+ *** Smooth digital Calibration configuration ***
+ ================================================
+ [..]
+ (+) Configure the RTC Original Digital Calibration Value and the corresponding
+ calibration cycle period (32s,16s and 8s) using the HAL_RTCEx_SetSmoothCalib()
+ function.
+
+ *** TimeStamp configuration ***
+ ===============================
+ [..]
+ (+) Enables the RTC TimeStamp using the HAL_RTC_SetTimeStamp() function.
+ You can also configure the RTC TimeStamp with interrupt mode using the
+ HAL_RTC_SetTimeStamp_IT() function.
+ (+) To read the RTC TimeStamp Time and Date register, use the HAL_RTC_GetTimeStamp()
+ function.
+
+ *** Tamper configuration ***
+ ============================
+ [..]
+ (+) Enable the RTC Tamper and Configure the Tamper filter count, trigger Edge
+ or Level according to the Tamper filter (if equal to 0 Edge else Level)
+ value, sampling frequency, NoErase, MaskFlag, precharge or discharge and
+ Pull-UP using the HAL_RTC_SetTamper() function. You can configure RTC Tamper
+ with interrupt mode using HAL_RTC_SetTamper_IT() function.
+ (+) The default configuration of the Tamper erases the backup registers. To avoid
+ erase, enable the NoErase field on the RTC_TAMPCR register.
+
+ *** Backup Data Registers configuration ***
+ ===========================================
+ [..]
+ (+) To write to the RTC Backup Data registers, use the HAL_RTC_BKUPWrite()
+ function.
+ (+) To read the RTC Backup Data registers, use the HAL_RTC_BKUPRead()
+ function.
+ (+) The backup registers are reset when a tamper detection event occurs
+
+
+ ##### RTC and low power modes #####
+ ==================================================================
+ [..] The MCU can be woken up from a low power mode by an RTC alternate
+ function.
+ [..] The RTC alternate functions are the RTC alarms (Alarm A and Alarm B),
+ RTC wakeup, RTC tamper event detection and RTC time stamp event detection.
+ These RTC alternate functions can wake up the system from the Stop and
+ Standby low power modes.
+ [..] The system can also wake up from low power modes without depending
+ on an external interrupt (Auto-wakeup mode), by using the RTC alarm
+ or the RTC wakeup events.
+ [..] The RTC provides a programmable time base for waking up from the
+ Stop or Standby mode at regular intervals.
+ Wakeup from STOP and Standby modes is possible only when the RTC clock source
+ is LSE or LSI.

+ [..] This section provides functions allowing to initialize and configure the
+ RTC Prescaler (Synchronous and Asynchronous), RTC Hour format, disable
+ RTC registers Write protection, enter and exit the RTC initialization mode,
+ RTC registers synchronization check and reference clock detection enable.
+ (#) The RTC Prescaler is programmed to generate the RTC 1Hz time base.
+ It is split into 2 programmable prescalers to minimize power consumption.
+ (++) A 7-bit asynchronous prescaler and a 13-bit synchronous prescaler.
+ (++) When both prescalers are used, it is recommended to configure the
+ asynchronous prescaler to a high value to minimize power consumption.
+ (#) All RTC registers are Write protected. Writing to the RTC registers
+ is enabled by writing a key into the Write Protection register, RTC_WPR.
+ (#) To configure the RTC Calendar, user application should enter

+ complete, the calendar restarts counting after 4 RTCCLK cycles.
+ (#) To read the calendar through the shadow registers after Calendar
+ initialization, calendar update or after wakeup from low power modes
+ the software must first clear the RSF flag. The software must then

+ that the calendar registers have been correctly copied into the
+ RTC_TR and RTC_DR shadow registers.The HAL_RTC_WaitForSynchro() function
+ implements the above software sequence (RSF clear and RSF check).

+ * @brief Extended RTC HAL module driver.
+ *
+ * This file provides firmware functions to manage the following
+ * functionalities of the Real Time Clock (RTC) Extension peripheral:
+ * + RTC Time Stamp functions
+ * + RTC Tamper functions
+ * + RTC Wake-up functions
+ * + Extension Control functions
+ * + Extension RTC features functions
+ *
+ @verbatim
+ ==============================================================================
+ ##### Backup Domain Operating Condition #####
+ ==============================================================================
+ [..] As long as the supply voltage remains in the operating range,
+ the RTC never stops, regardless of the device status (Run mode,
+ low power modes or under reset).
+
+ ##### Backup Domain Reset #####
+ ==================================================================
+ [..] The backup domain reset sets all RTC registers and the RCC_CSR register
+ to their reset values.
+ [..] A backup domain reset is generated when one of the following events occurs:
+ (+) Software reset, triggered by setting the RTCRST bit in the
+ RCC Control Status register (RCC_CSR).
+ (+) Power reset (BOR/POR/PDR).
+
+ ##### Backup Domain Access #####
+ ==================================================================
+ [..] After reset, the backup domain (RTC registers and RTC backup data registers)
+ is protected against possible unwanted write accesses.
+ [..] To enable access to the RTC Domain and RTC registers, proceed as follows:
+ (+) Enable the Power Controller (PWR) APB1 interface clock using the
+ __PWR_CLK_ENABLE() function.
+ (+) Enable access to RTC domain using the HAL_PWR_EnableBkUpAccess() function.
+ (+) Select the RTC clock source using the __HAL_RCC_RTC_CONFIG() function.
+ (+) Enable RTC Clock using the __HAL_RCC_RTC_ENABLE() function.
+
+
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ (+) Enable the RTC domain access.
+ (+) Configure the RTC Prescaler (Asynchronous and Synchronous) and RTC hour
+ format using the HAL_RTC_Init() function.
+
+ *** Time and Date configuration ***
+ ===================================
+ [..]
+ (+) To configure the RTC Calendar (Time and Date) use the HAL_RTC_SetTime()
+ and HAL_RTC_SetDate() functions.
+ (+) To read the RTC Calendar, use the HAL_RTC_GetTime() and HAL_RTC_GetDate() functions.
+
+ *** Alarm configuration ***
+ ===========================
+ [..]
+ (+) To configure the RTC Alarm use the HAL_RTC_SetAlarm() function.
+ You can also configure the RTC Alarm with interrupt mode using the HAL_RTC_SetAlarm_IT() function.
+ (+) To read the RTC Alarm, use the HAL_RTC_GetAlarm() function.
+
+ *** RTC Wakeup configuration ***
+ ================================
+ [..]
+ (+) To configure the RTC Wakeup Clock source and Counter use the HAL_RTC_SetWakeUpTimer()
+ function. You can also configure the RTC Wakeup timer in interrupt mode
+ using the HAL_RTC_SetWakeUpTimer_IT() function.
+ (+) To read the RTC WakeUp Counter register, use the HAL_RTC_GetWakeUpTimer()
+ function.
+
+ *** Outputs configuration ***
+ =============================
+ [..] The RTC has 2 different outputs:
+ (+) RTC_ALARM: this output is used to manage the RTC Alarm A, Alarm B
+ and WaKeUp signals.
+ To output the selected RTC signal, use the HAL_RTC_Init() function.
+ (+) RTC_CALIB: this output is 512Hz signal or 1Hz.
+ To enable the RTC_CALIB, use the HAL_RTCEx_SetCalibrationOutPut() function.
+ (+) Two pins can be used as RTC_ALARM or RTC_CALIB (PC13, PB14) managed on
+ the RTC_OR register.
+ (+) When the RTC_CALIB or RTC_ALARM output is selected, the RTC_OUT pin is
+ automatically configured in output alternate function.
+
+ *** Smooth digital Calibration configuration ***
+ ================================================
+ [..]
+ (+) Configure the RTC Original Digital Calibration Value and the corresponding
+ calibration cycle period (32s,16s and 8s) using the HAL_RTCEx_SetSmoothCalib()
+ function.
+
+ *** TimeStamp configuration ***
+ ===============================
+ [..]
+ (+) Enables the RTC TimeStamp using the HAL_RTC_SetTimeStamp() function.
+ You can also configure the RTC TimeStamp with interrupt mode using the
+ HAL_RTC_SetTimeStamp_IT() function.
+ (+) To read the RTC TimeStamp Time and Date register, use the HAL_RTC_GetTimeStamp()
+ function.
+
+ *** Tamper configuration ***
+ ============================
+ [..]
+ (+) Enable the RTC Tamper and Configure the Tamper filter count, trigger Edge
+ or Level according to the Tamper filter (if equal to 0 Edge else Level)
+ value, sampling frequency, NoErase, MaskFlag, precharge or discharge and
+ Pull-UP using the HAL_RTC_SetTamper() function. You can configure RTC Tamper
+ with interrupt mode using HAL_RTC_SetTamper_IT() function.
+ (+) The default configuration of the Tamper erases the backup registers. To avoid
+ erase, enable the NoErase field on the RTC_TAMPCR register.
+
+ *** Backup Data Registers configuration ***
+ ===========================================
+ [..]
+ (+) To write to the RTC Backup Data registers, use the HAL_RTC_BKUPWrite()
+ function.
+ (+) To read the RTC Backup Data registers, use the HAL_RTC_BKUPRead()
+ function.
+ (+) The backup registers are reset when a tamper detection event occurs
+
+
+ ##### RTC and low power modes #####
+ ==================================================================
+ [..] The MCU can be woken up from a low power mode by an RTC alternate
+ function.
+ [..] The RTC alternate functions are the RTC alarms (Alarm A and Alarm B),
+ RTC wakeup, RTC tamper event detection and RTC time stamp event detection.
+ These RTC alternate functions can wake up the system from the Stop and
+ Standby low power modes.
+ [..] The system can also wake up from low power modes without depending
+ on an external interrupt (Auto-wakeup mode), by using the RTC alarm
+ or the RTC wakeup events.
+ [..] The RTC provides a programmable time base for waking up from the
+ Stop or Standby mode at regular intervals.
+ Wakeup from STOP and Standby modes is possible only when the RTC clock source
+ is LSE or LSI.

+ * @brief SMARTCARD HAL module driver.
+ *
+ * This file provides firmware functions to manage the following
+ * functionalities of the SmartCard.
+ * + Initialization and de-initialization methods
+ * + IO operation methods
+ * + Peripheral Control methods
+ *
+ *
+ @verbatim
+ ===============================================================================
+ ##### How to use this driver #####
+ ===============================================================================
+ [..]
+ The SMARTCARD HAL driver can be used as follow:
+
+ (#) Declare a SMARTCARD_HandleTypeDef handle structure.
+ (#) Associate a USART to the SMARTCARD handle hsc.
+ (#) Initialize the SMARTCARD low level resources by implementing the HAL_SMARTCARD_MspInit ()API:
+ (##) Enable the USARTx interface clock.
+ (##) USART pins configuration:
+ (+) Enable the clock for the USART GPIOs.
+ (+) Configure these USART pins as alternate function pull-up.
+ (##) NVIC configuration if you need to use interrupt process (HAL_SMARTCARD_Transmit_IT()
+ and HAL_SMARTCARD_Receive_IT() APIs):
+ (+) Configure the USARTx interrupt priority.
+ (+) Enable the NVIC USART IRQ handle.
+ (@) The specific USART interrupts (Transmission complete interrupt,
+ RXNE interrupt and Error Interrupts) will be managed using the macros
+ __HAL_SMARTCARD_ENABLE_IT() and __HAL_SMARTCARD_DISABLE_IT() inside the transmit and receive process.
+ (##) DMA Configuration if you need to use DMA process (HAL_SMARTCARD_Transmit_DMA()
+ and HAL_SMARTCARD_Receive_DMA() APIs):
+ (+) Declare a DMA handle structure for the Tx/Rx stream.
+ (+) Enable the DMAx interface clock.
+ (+) Configure the declared DMA handle structure with the required Tx/Rx parameters.
+ (+) Configure the DMA Tx/Rx Stream.
+ (+) Associate the initialized DMA handle to the SMARTCARD DMA Tx/Rx handle.
+ (+) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx Stream.
+
+ (#) Program the Baud Rate, Parity, Mode(Receiver/Transmitter), clock enabling/disabling and accordingly,
+ the clock parameters (parity, phase, last bit), prescaler value, guard time and NACK on transmission
+ error enabling or disabling in the hsc Init structure.
+
+ (#) If required, program SMARTCARD advanced features (TX/RX pins swap, TimeOut, auto-retry counter,...)
+ in the hsc AdvancedInit structure.
+
+ (#) Initialize the SMARTCARD associated USART registers by calling
+ the HAL_SMARTCARD_Init() API.
+
+ (@) HAL_SMARTCARD_Init() API also configure also the low level Hardware GPIO, CLOCK, CORTEX...etc) by
+ calling the customized HAL_SMARTCARD_MspInit() API.

+ This subsection provides a set of functions allowing to initialize the USARTx
+ associated to the SmartCard.
+ (+) These parameters can be configured:
+ (++) Baud Rate
+ (++) Parity: parity should be enabled,
+ Frame Length is fixed to 8 bits plus parity:
+ the USART frame format is given in the following table:
+ +---------------------------------------------------------------+
+ | M1M0 bits | PCE bit | USART frame |
+ |-----------------------|---------------------------------------|
+ | 01 | 1 | | SB | 8 bit data | PB | STB | |
+ +---------------------------------------------------------------+
+ (++) Receiver/transmitter modes
+ (++) Synchronous mode (and if enabled, phase, polarity and last bit parameters)
+ (++) Prescaler value
+ (++) Guard bit time
+ (++) NACK enabling or disabling on transmission error
+
+ (+) The following advanced features can be configured as well:
+ (++) TX and/or RX pin level inversion
+ (++) data logical level inversion
+ (++) RX and TX pins swap
+ (++) RX overrun detection disabling
+ (++) DMA disabling on RX error
+ (++) MSB first on communication line
+ (++) Time out enabling (and if activated, timeout value)
+ (++) Block length
+ (++) Auto-retry counter
+
+ [..]
+ The HAL_SMARTCARD_Init() API follow respectively the USART (a)synchronous configuration procedures
+ (details for the procedures are available in reference manual).

+ @verbatim
+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ The SMBUS HAL driver can be used as follows:
+
+ (#) Declare a SMBUS_HandleTypeDef handle structure, for example:
+ SMBUS_HandleTypeDef hsmbus;
+
+ (#)Initialize the SMBUS low level resources by implement the HAL_SMBUS_MspInit ()API:
+ (##) Enable the SMBUSx interface clock
+ (##) SMBUS pins configuration
+ (+) Enable the clock for the SMBUS GPIOs
+ (+) Configure SMBUS pins as alternate function open-drain
+ (##) NVIC configuration if you need to use interrupt process
+ (+) Configure the SMBUSx interrupt priority
+ (+) Enable the NVIC SMBUS IRQ Channel
+
+ (#) Configure the Communication Clock Timing, Bus Timeout, Own Address1, Master Adressing Mode,
+ Dual Addressing mode, Own Address2, Own Address2 Mask, General call, Nostretch mode,
+ Peripheral mode and Packet Error Check mode in the hsmbus Init structure.
+
+ (#) Initialize the SMBUS registers by calling the HAL_SMBUS_Init() API:
+ (+) These API's configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
+ by calling the customed HAL_SMBUS_MspInit(&hsmbus) API.
+
+ (#) To check if target device is ready for communication, use the function HAL_SMBUS_IsDeviceReady()
+
+ (#) For SMBUS IO operations, only one mode of operations is available within this driver :
+
+ *** Interrupt mode IO operation ***
+ ===================================
+ [..]
+ (+) Transmit in master/host SMBUS mode an amount of data in non blocking mode using HAL_SMBUS_Master_Transmit_IT()
+ (++) At transmission end of transfer HAL_SMBUS_MasterTxCpltCallback is executed and user can
+ add his own code by customization of function pointer HAL_SMBUS_MasterTxCpltCallback
+ (+) Receive in master/host SMBUS mode an amount of data in non blocking mode using HAL_SMBUS_Master_Receive_IT()
+ (++) At reception end of transfer HAL_SMBUS_MasterRxCpltCallback is executed and user can
+ add his own code by customization of function pointer HAL_SMBUS_MasterRxCpltCallback
+ (+) Abort a master/host SMBUS process commnunication with Interrupt using HAL_SMBUS_Master_Abort_IT()
+ (++) The associated previous transfer callback is called at the end of abort process
+ (++) mean HAL_SMBUS_MasterTxCpltCallback in case of previous state was master transmit
+ (++) mean HAL_SMBUS_MasterRxCpltCallback in case of previous state was master receive
+ (+) Enable the Address listen mode in slave/device SMBUS mode using HAL_SMBUS_Slave_Listen_IT()
+ (++) When address slave/device SMBUS match, HAL_SMBUS_SlaveAddrCallback is executed and user can
+ add his own code to check the Address Match Code and the transmission direction request by master/host (Write/Read).
+ (++) At Listen mode end HAL_SMBUS_SlaveListenCpltCallback is executed and user can
+ add his own code by customization of function pointer HAL_SMBUS_SlaveListenCpltCallback
+ (+) Transmit in slave/device SMBUS mode an amount of data in non blocking mode using HAL_SMBUS_Slave_Transmit_IT()
+ (++) At transmission end of transfer HAL_SMBUS_SlaveTxCpltCallback is executed and user can
+ add his own code by customization of function pointer HAL_SMBUS_SlaveTxCpltCallback
+ (+) Receive in slave/device SMBUS mode an amount of data in non blocking mode using HAL_SMBUS_Slave_Receive_IT()
+ (++) At reception end of transfer HAL_SMBUS_SlaveRxCpltCallback is executed and user can
+ add his own code by customization of function pointer HAL_SMBUS_SlaveRxCpltCallback
+ (+) Enable/Disable the SMBUS alert mode using HAL_SMBUS_EnableAlert_IT() HAL_SMBUS_DisableAlert_IT()
+ (++) When SMBUS Alert is generated HAL_SMBUS_ErrorCallback() is executed and user can
+ add his own code by customization of function pointer HAL_SMBUS_ErrorCallback
+ to check the Alert Error Code using function HAL_SMBUS_GetError()
+ (+) Get HAL state machine or error values using HAL_SMBUS_GetState() or HAL_SMBUS_GetError()
+ (+) In case of transfer Error, HAL_SMBUS_ErrorCallback() function is executed and user can
+ add his own code by customization of function pointer HAL_SMBUS_ErrorCallback
+ to check the Error Code using function HAL_SMBUS_GetError()
+
+ *** SMBUS HAL driver macros list ***
+ ==================================
+ [..]
+ Below the list of most used macros in SMBUS HAL driver.
+
+ (+) __HAL_SMBUS_ENABLE: Enable the SMBUS peripheral
+ (+) __HAL_SMBUS_DISABLE: Disable the SMBUS peripheral
+ (+) __HAL_SMBUS_GET_FLAG : Checks whether the specified SMBUS flag is set or not
+ (+) __HAL_SMBUS_CLEAR_FLAG : Clears the specified SMBUS pending flag
+ (+) __HAL_SMBUS_ENABLE_IT: Enables the specified SMBUS interrupt
+ (+) __HAL_SMBUS_DISABLE_IT: Disables the specified SMBUS interrupt
+
+ [..]
+ (@) You can refer to the SMBUS HAL driver header file for more useful macros

+ * @brief SPI HAL module driver.
+ *
+ * This file provides firmware functions to manage the following
+ * functionalities of the Serial Peripheral Interface (SPI) peripheral:
+ * + Initialization and de-initialization functions
+ * + IO operation functions
+ * + Peripheral Control functions
+ * + Peripheral State functions
+ @verbatim
+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ The SPI HAL driver can be used as follows:
+
+ (#) Declare a SPI_HandleTypeDef handle structure, for example:
+ SPI_HandleTypeDef hspi;
+
+ (#)Initialize the SPI low level resources by implement the HAL_SPI_MspInit ()API:
+ (##) Enable the SPIx interface clock
+ (##) SPI pins configuration
+ (+++) Enable the clock for the SPI GPIOs
+ (+++) Configure these SPI pins as alternate function push-pull
+ (##) NVIC configuration if you need to use interrupt process
+ (+++) Configure the SPIx interrupt priority
+ (+++) Enable the NVIC SPI IRQ handle
+ (##) DMA Configuration if you need to use DMA process
+ (+++) Declare a DMA_HandleTypeDef handle structure for the transmit or receive stream
+ (+++) Enable the DMAx interface clock using
+ (+++) Configure the DMA handle parameters
+ (+++) Configure the DMA Tx or Rx Stream
+ (+++) Associate the initilalized hdma_tx handle to the hspi DMA Tx or Rx handle
+ (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx or Rx Stream
+
+ (#) Program the Mode, Direction , Data size, Baudrate Prescaler, NSS
+ management, Clock polarity and phase, FirstBit and CRC configuration in the hspi Init structure.
+
+ (#) Initialize the SPI registers by calling the HAL_SPI_Init() API:
+ (++) This API configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
+ by calling the customed HAL_SPI_MspInit(&hspi) API.
+ [..]
+ Circular mode restriction:
+ (#) The DMA circular mode cannot be used when the SPI is configured in these modes:
+ (##) Master 2Lines RxOnly
+ (##) Master 1Line Rx
+ (#) The CRC feature is not managed when the DMA circular mode is enabled
+ (#) When the SPI DMA Pause/Stop features are used, we must use the following APIs
+ the HAL_SPI_DMAPause()/ HAL_SPI_DMAStop() only under the SPI callbacks
+
+ [..]
+ Using the HAL it is not possible to reach all supported SPI frequency with the differents SPI Modes,
+ the following table resume the max SPI frequency reached with data size 8bits/16bits:
+ +-----------------------------------------------------------------------------------------+
+ | | | 2Lines Fullduplex | 2Lines RxOnly | 1Line |
+ | Process | Tranfert mode |--------------------|--------------------|--------------------|
+ | | | Master | Slave | Master | Slave | Master | Slave |
+ |=========================================================================================|
+ | T | Polling | Fcpu/2 | Fcpu/2 | NA | NA | NA | NA |
+ | X |----------------|----------|---------|----------|---------|----------|---------|
+ | / | Interrupt | Fcpu/4 | Fcpu/16 | NA | NA | NA | NA |
+ | R |----------------|----------|---------|----------|---------|----------|---------|
+ | X | DMA | Fcpu/2 | Fcpu/2 | NA | NA | NA | NA |
+ |=========|================|==========|=========|==========|=========|==========|=========|
+ | | Polling | Fcpu/2 | Fcpu/4 | Fcpu/16 | Fcpu/8 | Fcpu/8 | Fcpu/8 |
+ | |----------------|----------|---------|----------|---------|----------|---------|
+ | R | Interrupt | Fcpu/8 | Fcpu/16 | Fcpu/8 | Fcpu/8 | Fcpu/8 | Fcpu/4 |
+ | X |----------------|----------|---------|----------|---------|----------|---------|
+ | | DMA | Fcpu/4 | Fcpu/2 | Fcpu/4 | Fcpu/16 | Fcpu/2 | Fcpu/16 |
+ |=========|================|==========|=========|==========|=========|==========|=========|
+ | | Polling | Fcpu/2 | Fcpu/2 | NA | NA | Fcpu/8 | Fcpu/8 |
+ | |----------------|----------|---------|----------|---------|----------|---------|
+ | T | Interrupt | Fcpu/2 | Fcpu/4 | NA | NA | Fcpu/16 | Fcpu/8 |
+ | X |----------------|----------|---------|----------|---------|----------|---------|
+ | | DMA | Fcpu/2 | Fcpu/2 | NA | NA | Fcpu/8 | Fcpu/16 |
+ +-----------------------------------------------------------------------------------------+
+ @note The max SPI frequency depend on SPI data size (4bits, 5bits,..., 8bits,...15bits, 16bits),
+ SPI mode(2 Lines fullduplex, 2 lines RxOnly, 1 line TX/RX) and Process mode (Polling, IT, DMA).
+ @note
+ (#) TX/RX processes are HAL_SPI_TransmitReceive(), HAL_SPI_TransmitReceive_IT() and HAL_SPI_TransmitReceive_DMA()
+ (#) RX processes are HAL_SPI_Receive(), HAL_SPI_Receive_IT() and HAL_SPI_Receive_DMA()
+ (#) TX processes are HAL_SPI_Transmit(), HAL_SPI_Transmit_IT() and HAL_SPI_Transmit_DMA()

+ ==============================================================================
+ ##### IO operation functions #####
+ ===============================================================================
+ This subsection provides a set of functions allowing to manage the SPI
+ data transfers.
+
+ [..] The SPI supports master and slave mode :
+
+ (#) There are two mode of transfer:
+ (++) Blocking mode: The communication is performed in polling mode.
+ The HAL status of all data processing is returned by the same function
+ after finishing transfer.
+ (++) No-Blocking mode: The communication is performed using Interrupts
+ or DMA, These API's return the HAL status.
+ The end of the data processing will be indicated through the
+ dedicated SPI IRQ when using Interrupt mode or the DMA IRQ when
+ using DMA mode.
+ The HAL_SPI_TxCpltCallback(), HAL_SPI_RxCpltCallback() and HAL_SPI_TxRxCpltCallback() user callbacks
+ will be executed respectivelly at the end of the transmit or Receive process
+ The HAL_SPI_ErrorCallback()user callback will be executed when a communication error is detected
+
+ (#) Blocking mode API's are :
+ (++) HAL_SPI_Transmit()in 1Line (simplex) and 2Lines (full duplex) mode
+ (++) HAL_SPI_Receive() in 1Line (simplex) and 2Lines (full duplex) mode
+ (++) HAL_SPI_TransmitReceive() in full duplex mode
+
+ (#) Non-Blocking mode API's with Interrupt are :
+ (++) HAL_SPI_Transmit_IT()in 1Line (simplex) and 2Lines (full duplex) mode
+ (++) HAL_SPI_Receive_IT() in 1Line (simplex) and 2Lines (full duplex) mode
+ (++) HAL_SPI_TransmitReceive_IT()in full duplex mode
+ (++) HAL_SPI_IRQHandler()
+
+ (#) No-Blocking mode functions with DMA are :
+ (++) HAL_SPI_Transmit_DMA()in 1Line (simplex) and 2Lines (full duplex) mode
+ (++) HAL_SPI_Receive_DMA() in 1Line (simplex) and 2Lines (full duplex) mode
+ (++) HAL_SPI_TransmitReceie_DMA() in full duplex mode
+
+ (#) A set of Transfer Complete Callbacks are provided in No_Blocking mode:
+ (++) HAL_SPI_TxCpltCallback()
+ (++) HAL_SPI_RxCpltCallback()
+ (++) HAL_SPI_ErrorCallback()
+ (++) HAL_SPI_TxRxCpltCallback()

+ ==============================================================================
+ ##### TIMER Generic features #####
+ ==============================================================================
+ [..] The Timer features include:
+ (#) 16-bit up, down, up/down auto-reload counter.
+ (#) 16-bit programmable prescaler allowing dividing (also on the fly) the counter clock
+ frequency either by any factor between 1 and 65536.
+ (#) Up to 4 independent channels for:
+ (++) Input Capture
+ (++) Output Compare
+ (++) PWM generation (Edge and Center-aligned Mode)
+ (++) One-pulse mode output
+ (#) Synchronization circuit to control the timer with external signals and to interconnect
+ several timers together.
+ (#) Supports incremental (quadrature) encoder and hall-sensor circuitry for positioning
+ purposes
+
+ ##### How to use this driver #####
+================================================================================
+ [..]
+ (#) Enable the TIM interface clock using
+ __TIMx_CLK_ENABLE();
+
+ (#) TIM pins configuration
+ (++) Enable the clock for the TIM GPIOs using the following function:
+ __GPIOx_CLK_ENABLE();
+ (++) Configure these TIM pins in Alternate function mode using HAL_GPIO_Init();
+
+ (#) The external Clock can be configured, if needed (the default clock is the internal clock from the APBx),
+ using the following function:
+ HAL_TIM_ConfigClockSource, the clock configuration should be done before any start function.
+
+ (#) Configure the TIM in the desired functioning mode using one of the
+ initialization function of this driver:
+ (++) HAL_TIM_Base_Init: to use the Timer to generate a simple time base
+ (++) HAL_TIM_OC_Init and HAL_TIM_OC_ConfigChannel: to use the Timer to generate an
+ Output Compare signal.
+ (++) HAL_TIM_PWM_Init and HAL_TIM_PWM_ConfigChannel: to use the Timer to generate a
+ PWM signal.
+ (++) HAL_TIM_IC_Init and HAL_TIM_IC_ConfigChannel: to use the Timer to measure an
+ external signal.
+ (++) HAL_TIM_OnePulse_Init and HAL_TIM_OnePulse_ConfigChannel: to use the Timer in One Pulse Mode.
+ (++) HAL_TIM_Encoder_Init: to use the Timer Encoder Interface.
+
+ (#) Activate the TIM peripheral using one of the start functions:
+ HAL_TIM_Base_Start(), HAL_TIM_Base_Start_DMA(), HAL_TIM_Base_Start_IT(),
+ HAL_TIM_OC_Start(), HAL_TIM_OC_Start_DMA(), HAL_TIM_OC_Start_IT(),
+ HAL_TIM_IC_Start(), HAL_TIM_IC_Start_DMA(), HAL_TIM_IC_Start_IT(),
+ HAL_TIM_PWM_Start(), HAL_TIM_PWM_Start_DMA(), HAL_TIM_PWM_Start_IT(),
+ HAL_TIM_OnePulse_Start(), HAL_TIM_OnePulse_Start_IT(),
+ HAL_TIM_Encoder_Start(), HAL_TIM_Encoder_Start_DMA() or HAL_TIM_Encoder_Start_IT()
+
+ (#) The DMA Burst is managed with the two following functions:
+ HAL_TIM_DMABurst_WriteStart
+ HAL_TIM_DMABurst_ReadStart

+ * @author MCD Application Team
+ * @version V1.1.0
+ * @date 18-June-2014
+ * @brief TIM HAL module driver.
+ * @brief This file provides firmware functions to manage the following
+ * functionalities of the Timer (TIM) peripheral:
+ * + Time Hall Sensor Interface Initialization
+ * + Time Hall Sensor Interface Start
+ * + Time Master and Slave synchronization configuration
+ @verbatim
+================================================================================
+ ##### TIM specific features integration #####
+================================================================================
+
+ [..] The Timer features include:
+ (#) 16-bit up, down, up/down auto-reload counter.
+ (#) 16-bit programmable prescaler allowing dividing (also on the fly) the counter clock
+ frequency either by any factor between 1 and 65536.
+ (#) Up to 4 independent channels for:
+ Input Capture
+ Output Compare
+ PWM generation (Edge and Center-aligned Mode)
+ One-pulse mode output
+ (#) Synchronization circuit to control the timer with external signals and to interconnect
+ several timers together.
+ (#) Supports incremental (quadrature) encoder and hall-sensor circuitry for positioning
+ purposes
+
+ ##### How to use this driver #####
+================================================================================
+ [..]
+ (#) Enable the TIM interface clock using
+ __TIMx_CLK_ENABLE();
+
+ (#) TIM pins configuration
+ (++) Enable the clock for the TIM GPIOs using the following function:
+ __GPIOx_CLK_ENABLE();
+ (++) Configure these TIM pins in Alternate function mode using HAL_GPIO_Init();
+
+ (#) The external Clock can be configured, if needed (the default clock is the internal clock from the APBx),
+ using the following function:
+ HAL_TIM_ConfigClockSource, the clock configuration should be done before any start function.
+
+ (#) Configure the TIM in the desired operating mode using one of the
+ configuration function of this driver:
+ (++) HAL_TIMEx_MasterConfigSynchronization() to configure the peripheral in master mode.
+
+ (#) Remap the Timer I/O using HAL_TIMEx_RemapConfig() API.

+ * @author MCD Application Team
+ * @version V1.1.0
+ * @date 18-June-2014
+ * @brief This file provides firmware functions to manage the following
+ * functionalities of the Touch Sensing Controller (TSC) peripheral:
+ * + Initialization and DeInitialization
+ * + Channel IOs, Shield IOs and Sampling IOs configuration
+ * + Start and Stop an acquisition
+ * + Read acquisition result
+ * + Interrupts and flags management
+ *
+ @verbatim
+================================================================================
+ ##### TSC specific features #####
+================================================================================
+ [..]
+ (#) Proven and robust surface charge transfer acquisition principle
+
+ (#) Supports up to 3 capacitive sensing channels per group
+
+ (#) Capacitive sensing channels can be acquired in parallel offering a very good
+ response time
+
+ (#) Spread spectrum feature to improve system robustness in noisy environments
+
+ (#) Full hardware management of the charge transfer acquisition sequence
+
+ (#) Programmable charge transfer frequency
+
+ (#) Programmable sampling capacitor I/O pin
+
+ (#) Programmable channel I/O pin
+
+ (#) Programmable max count value to avoid long acquisition when a channel is faulty
+
+ (#) Dedicated end of acquisition and max count error flags with interrupt capability
+
+ (#) One sampling capacitor for up to 3 capacitive sensing channels to reduce the system
+ components
+
+ (#) Compatible with proximity, touchkey, linear and rotary touch sensor implementation
+
+
+ ##### How to use this driver #####
+================================================================================
+ [..]
+ (#) Enable the TSC interface clock using __TSC_CLK_ENABLE() macro.
+
+ (#) GPIO pins configuration
+ (++) Enable the clock for the TSC GPIOs using __GPIOx_CLK_ENABLE() macro.
+ (++) Configure the TSC pins used as sampling IOs in alternate function output Open-Drain mode,
+ and TSC pins used as channel/shield IOs in alternate function output Push-Pull mode
+ using HAL_GPIO_Init() function.
+ (++) Configure the alternate function on all the TSC pins using HAL_xxxx() function.
+
+ (#) Interrupts configuration
+ (++) Configure the NVIC (if the interrupt model is used) using HAL_xxx() function.
+
+ (#) TSC configuration
+ (++) Configure all TSC parameters and used TSC IOs using HAL_TSC_Init() function.
+
+ *** Acquisition sequence ***
+ ===================================
+ [..]
+ (+) Discharge all IOs using HAL_TSC_IODischarge() function.
+ (+) Wait a certain time allowing a good discharge of all capacitors. This delay depends
+ of the sampling capacitor and electrodes design.
+ (+) Select the channel IOs to be acquired using HAL_TSC_IOConfig() function.
+ (+) Launch the acquisition using either HAL_TSC_Start() or HAL_TSC_Start_IT() function.
+ If the synchronized mode is selected, the acquisition will start as soon as the signal
+ is received on the synchro pin.
+ (+) Wait the end of acquisition using either HAL_TSC_PollForAcquisition() or
+ HAL_TSC_GetState() function or using WFI instruction for example.
+ (+) Check the group acquisition status using HAL_TSC_GroupGetStatus() function.
+ (+) Read the acquisition value using HAL_TSC_GroupGetValue() function.

+ * + Initialization and de-initialization methods
+ * + IO operation methods
+ * + Peripheral Control methods
+ *
+ @verbatim
+ ===============================================================================
+ ##### How to use this driver #####
+ ===============================================================================
+ [..]
+ The UART HAL driver can be used as follows:
+
+ (#) Declare a UART_HandleTypeDef handle structure.
+
+ (#) Initialize the UART low level resources by implementing the HAL_UART_MspInit() API:
+ (##) Enable the USARTx interface clock.
+ (##) UART pins configuration:
+ (+++) Enable the clock for the UART GPIOs.
+ (+++) Configure these UART pins as alternate function pull-up.
+ (##) NVIC configuration if you need to use interrupt process (HAL_UART_Transmit_IT()
+ and HAL_UART_Receive_IT() APIs):
+ (+++) Configure the USARTx interrupt priority.
+ (+++) Enable the NVIC USART IRQ handle.
+
+ (##) DMA Configuration if you need to use DMA process (HAL_UART_Transmit_DMA()
+ and HAL_UART_Receive_DMA() APIs):
+ (+++) Declare a DMA handle structure for the Tx/Rx stream.
+ (+++) Enable the DMAx interface clock.
+ (+++) Configure the declared DMA handle structure with the required
+ Tx/Rx parameters.
+ (+++) Configure the DMA Tx/Rx Stream.
+ (+++) Associate the initialized DMA handle to the UART DMA Tx/Rx handle.
+ (+++) Configure the priority and enable the NVIC for the transfer complete
+ interrupt on the DMA Tx/Rx Stream.
+
+ (#) Program the Baud Rate, Word Length, Stop Bit, Parity, Hardware
+ flow control and Mode(Receiver/Transmitter) in the Init structure.
+
+ (#) For the UART asynchronous mode, initialize the UART registers by calling
+ the HAL_UART_Init() API.
+
+ (#) For the UART Half duplex mode, initialize the UART registers by calling
+ the HAL_HalfDuplex_Init() API.
+
+ (#) For the LIN mode, initialize the UART registers by calling the HAL_LIN_Init() API.
+
+ (#) For the Multi-Processor mode, initialize the UART registers by calling
+ the HAL_MultiProcessor_Init() API.
+
+ [..]
+ (@) The specific UART interrupts (Transmission complete interrupt,
+ RXNE interrupt and Error Interrupts) will be managed using the macros
+ __HAL_UART_ENABLE_IT() and __HAL_UART_DISABLE_IT() inside the transmit
+ and receive process.
+
+ [..]
+ (@) These APIs (HAL_UART_Init() and HAL_HalfDuplex_Init()) configure also the
+ low level Hardware GPIO, CLOCK, CORTEX...etc) by calling the customed
+ HAL_UART_MspInit() API.
+
+ [..]
+ Three operation modes are available within this driver :

+ (+) Send an amount of data in blocking mode using HAL_UART_Transmit()
+ (+) Receive an amount of data in blocking mode using HAL_UART_Receive()
+
+ *** Interrupt mode IO operation ***
+ ===================================
+ [..]
+ (+) Send an amount of data in non blocking mode using HAL_UART_Transmit_IT()

+ add his own code by customization of function pointer HAL_UART_TxHalfCpltCallback
+ (+) At transmission end of transfer HAL_UART_TxCpltCallback is executed and user can
+ add his own code by customization of function pointer HAL_UART_TxCpltCallback

+
+ *** DMA mode IO operation ***
+ ==============================

+ add his own code by customization of function pointer HAL_UART_TxHalfCpltCallback
+ (+) At transmission end of transfer HAL_UART_TxCpltCallback is executed and user can
+ add his own code by customization of function pointer HAL_UART_TxCpltCallback
+ (+) Receive an amount of data in non blocking mode (DMA) using HAL_UART_Receive_DMA()
+ (+) At reception end of half transfer HAL_UART_RxHalfCpltCallback is executed and user can

+ (+) Stop the DMA Transfer using HAL_UART_DMAStop()
+
+ *** UART HAL driver macros list ***
+ =============================================
+ [..]
+ Below the list of most used macros in UART HAL driver.
+
+ (+) __HAL_UART_ENABLE: Enable the UART peripheral
+ (+) __HAL_UART_DISABLE: Disable the UART peripheral
+ (+) __HAL_UART_GET_FLAG : Check whether the specified UART flag is set or not
+ (+) __HAL_UART_CLEAR_FLAG : Clear the specified UART pending flag
+ (+) __HAL_UART_ENABLE_IT: Enable the specified UART interrupt
+ (+) __HAL_UART_DISABLE_IT: Disable the specified UART interrupt

+ ===============================================================================
+ [..]
+ This subsection provides a set of functions allowing to initialize the USARTx or the UARTy
+ in asynchronous mode.
+ (+) For the asynchronous mode only these parameters can be configured:
+ (++) Baud Rate
+ (++) Word Length
+ (++) Stop Bit
+ (++) Parity: If the parity is enabled, then the MSB bit of the data written
+ in the data register is transmitted but is changed by the parity bit.
+ Depending on the frame length defined by the M bit (8-bits or 9-bits),
+ the possible UART frame formats are as listed in the following table:
+ +-----------------------------------------------------------------------+
+ | M1 bit | M0 bit | PCE bit | USART frame |
+ |---------|---------|-----------|---------------------------------------|
+ | 0 | 0 | 0 | | SB | 8 bit data | STB | |
+ |---------|---------|-----------|---------------------------------------|
+ | 0 | 0 | 1 | | SB | 7 bit data | PB | STB | |
+ |---------|---------|-----------|---------------------------------------|
+ | 0 | 1 | 0 | | SB | 9 bit data | STB | |
+ |---------|---------|-----------|---------------------------------------|
+ | 0 | 1 | 1 | | SB | 8 bit data | PB | STB | |
+ |---------|---------|-----------|---------------------------------------|
+ | 1 | 0 | 0 | | SB | 7 bit data | STB | |
+ |---------|---------|-----------|---------------------------------------|
+ | 1 | 0 | 1 | | SB | 6 bit data | PB | STB | |
+ +-----------------------------------------------------------------------+
+ (++) Hardware flow control
+ (++) Receiver/transmitter modes
+ (++) Over Sampling Method
+ (++) One-Bit Sampling Method
+ (+) For the asynchronous mode, the following advanced features can be configured as well:
+ (++) TX and/or RX pin level inversion
+ (++) data logical level inversion
+ (++) RX and TX pins swap
+ (++) RX overrun detection disabling
+ (++) DMA disabling on RX error
+ (++) MSB first on communication line
+ (++) auto Baud rate detection
+ [..]
+ The HAL_UART_Init(), HAL_HalfDuplex_Init(), HAL_LIN_Init()and HAL_MultiProcessorEx_Init()API
+ follow respectively the UART asynchronous, UART Half duplex, UART LIN mode
+ and UART multiprocessor mode mode configuration procedures (details for the procedures
+ are available in reference manual).

+ ##### IO operation functions #####
+ ===============================================================================
+ This subsection provides a set of functions allowing to manage the UART asynchronous
+ and Half duplex data transfers.
+
+ (#) There are two mode of transfer:
+ (+) Blocking mode: The communication is performed in polling mode.
+ The HAL status of all data processing is returned by the same function
+ after finishing transfer.
+ (+) No-Blocking mode: The communication is performed using Interrupts
+ or DMA, These API's return the HAL status.
+ The end of the data processing will be indicated through the
+ dedicated UART IRQ when using Interrupt mode or the DMA IRQ when
+ using DMA mode.
+ The HAL_UART_TxCpltCallback(), HAL_UART_RxCpltCallback() user callbacks
+ will be executed respectivelly at the end of the transmit or Receive process
+ The HAL_UART_ErrorCallback()user callback will be executed when a communication error is detected
+
+ (#) Blocking mode API's are :
+ (+) HAL_UART_Transmit()
+ (+) HAL_UART_Receive()
+
+ (#) Non-Blocking mode API's with Interrupt are :
+ (+) HAL_UART_Transmit_IT()
+ (+) HAL_UART_Receive_IT()
+ (+) HAL_UART_IRQHandler()
+ (+) UART_Transmit_IT()
+ (+) UART_Receive_IT()
+
+ (#) No-Blocking mode API's with DMA are :
+ (+) HAL_UART_Transmit_DMA()
+ (+) HAL_UART_Receive_DMA()
+ (+) HAL_UART_DMAPause()
+ (+) HAL_UART_DMAResume()
+ (+) HAL_UART_DMAStop()
+
+ (#) A set of Transfer Complete Callbacks are provided in No_Blocking mode:
+ (+) HAL_UART_TxHalfCpltCallback()
+ (+) HAL_UART_TxCpltCallback()
+ (+) HAL_UART_RxHalfCpltCallback()
+ (+) HAL_UART_RxCpltCallback()
+ (+) HAL_UART_ErrorCallback()
+
+ -@- In the Half duplex communication, it is forbidden to run the transmit
+ and receive process in parallel, the UART state HAL_UART_STATE_BUSY_TX_RX can't be useful.

+ ===============================================================================
+ ##### How to use this driver #####
+ ===============================================================================
+ [..]
+ The USART HAL driver can be used as follows:
+
+ (#) Declare a USART_HandleTypeDef handle structure.
+ (#) Initialize the USART low level resources by implement the HAL_USART_MspInit ()API:
+ (##) Enable the USARTx interface clock.
+ (##) USART pins configuration:
+ (+++) Enable the clock for the USART GPIOs.
+ (+++) Configure these USART pins as alternate function pull-up.
+ (##) NVIC configuration if you need to use interrupt process (HAL_USART_Transmit_IT(),
+ HAL_USART_Receive_IT() and HAL_USART_TransmitReceive_IT() APIs):
+ (+++) Configure the USARTx interrupt priority.
+ (+++) Enable the NVIC USART IRQ handle.
+ (@) The specific USART interrupts (Transmission complete interrupt,
+ RXNE interrupt and Error Interrupts) will be managed using the macros
+ __HAL_USART_ENABLE_IT() and __HAL_USART_DISABLE_IT() inside the transmit and receive process.
+ (##) DMA Configuration if you need to use DMA process (HAL_USART_Transmit_DMA()
+ HAL_USART_Receive_IT() and HAL_USART_TransmitReceive_IT() APIs):
+ (+++) Declare a DMA handle structure for the Tx/Rx stream.
+ (+++) Enable the DMAx interface clock.
+ (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.
+ (+++) Configure the DMA Tx/Rx Stream.
+ (+++) Associate the initilalized DMA handle to the USART DMA Tx/Rx handle.
+ (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx Stream.
+
+ (#) Program the Baud Rate, Word Length, Stop Bit, Parity, Hardware
+ flow control and Mode(Receiver/Transmitter) in the husart Init structure.
+
+ (#) Initialize the USART registers by calling the HAL_USART_Init() API:
+ (+) These API's configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
+ by calling the customed HAL_USART_MspInit(&husart) API.

+ This subsection provides a set of functions allowing to initialize the USART
+ in asynchronous and in synchronous modes.
+ (+) For the asynchronous mode only these parameters can be configured:
+ (++) Baud Rate
+ (++) Word Length
+ (++) Stop Bit
+ (++) Parity: If the parity is enabled, then the MSB bit of the data written
+ in the data register is transmitted but is changed by the parity bit.
+ Depending on the frame length defined by the M bit (8-bits or 9-bits),
+ the possible USART frame formats are as listed in the following table:
+ +-------------------------------------------------------------+
+ | M0 bit | PCE bit | USART frame |
+ |---------------------|---------------------------------------|
+ | 0 | 0 | | SB | 8 bit data | STB | |
+ |---------|-----------|---------------------------------------|

+ |---------|-----------|---------------------------------------|
+ | 1 | 1 | | SB | 8 bit data | PB | STB | |
+ +-------------------------------------------------------------+
+ (++) USART polarity
+ (++) USART phase
+ (++) USART LastBit
+ (++) Receiver/transmitter modes
+
+ [..]
+ The HAL_USART_Init() function follows the USART synchronous configuration
+ procedure (details for the procedure are available in reference manual (RM0329)).

+ * This file provides firmware functions to manage the following
+ * functionalities of the Window Watchdog (WWDG) peripheral:
+ * + Initialization and de-initialization functions
+ * + IO operation functions
+ * + Peripheral State functions
+ @verbatim
+ ==============================================================================
+ ##### WWDG specific features #####
+ ==============================================================================
+ [..]
+ Once enabled the WWDG generates a system reset on expiry of a programmed
+ time period, unless the program refreshes the counter (downcounter)
+ before reaching 0x3F value (i.e. a reset is generated when the counter
+ value rolls over from 0x40 to 0x3F).
+
+ (+) An MCU reset is also generated if the counter value is refreshed
+ before the counter has reached the refresh window value. This
+ implies that the counter must be refreshed in a limited window.
+ (+) Once enabled the WWDG cannot be disabled except by a system reset.
+ (+) WWDGRST flag in RCC_CSR register can be used to inform when a WWDG
+ reset occurs.
+ (+) The WWDG counter input clock is derived from the APB clock divided
+ by a programmable prescaler.
+ (+) WWDG counter clock = PCLK1 / Prescaler
+ WWDG timeout = (WWDG counter clock) * (counter value)
+ (+) Min-max timeout value @32 MHz(PCLK1): ~128.0 us / ~65.54 ms
+
+
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ (+) Enable WWDG APB1 clock using __WWDG_CLK_ENABLE().
+ (+) Set the WWDG prescaler, refresh window and counter value
+ using HAL_WWDG_Init() function.
+ (+) Start the WWDG using HAL_WWDG_Start() function.
+ When the WWDG is enabled the counter value should be configured to
+ a value greater than 0x40 to prevent generating an immediate reset.
+ (+) Optionally you can enable the Early Wakeup Interrupt (EWI) which is
+ generated when the counter reaches 0x40, and then start the WWDG using
+ HAL_WWDG_Start_IT().
+ Once enabled, EWI interrupt cannot be disabled except by a system reset.
+ (+) Then the application program must refresh the WWDG counter at regular
+ intervals during normal operation to prevent an MCU reset, using
+ HAL_WWDG_Refresh() function. This operation must occur only when
+ the counter is lower than the refresh window value already programmed.
+
+ *** WWDG HAL driver macros list ***
+ ==================================
+ [..]
+ Below the list of most used macros in WWDG HAL driver.
+
+ (+) __HAL_WWDG_ENABLE: Enable the WWDG peripheral
+ (+) __HAL_WWDG_GET_FLAG: Get the selected WWDG's flag status
+ (+) __HAL_WWDG_CLEAR_FLAG: Clear the WWDG's pending flags
+ (+) __HAL_WWDG_ENABLE_IT: Enables the WWDG early wakeup interrupt
