+  *            This module performs:
+  *                - Set the initial SP
+  *                - Set the initial PC == Reset_Handler,
+  *                - Set the vector table entries with the exceptions ISR address
+  *                - Branches to main in the C library (which eventually
+  *                  calls main()).
+  *            After Reset the Cortex-M4 processor is in Thread mode,
+  *            priority is Privileged, and the Stack is set to Main.

+  *              - To use or not the peripheral’s drivers in application code(i.e. 
+  *                code will be based on direct access to peripheral’s registers 
+  *                rather than drivers API), this option is controlled by

+     ==============================
+     [..]    
+       (+) Start the ADC peripheral using HAL_ADC_Start_DMA(), at this stage the user specify the length 
+           of data to be transfered at each end of conversion 
+       (+) At The end of data transfer by HAL_ADC_ConvCpltCallback() function is executed and user can

+  ==============================================================================
+                    ##### How to use this driver #####
+  ==============================================================================
+    [..]
+    (#)Initialize the ADC low level resources by implementing the HAL_ADC_MspInit():
+       (##) Enable the ADC interface clock using __ADC_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() 
+       (##) In case of using interrupts (e.g. HAL_ADC_Start_IT())
+             (+++) Configure the ADC interrupt priority using HAL_NVIC_SetPriority()
+             (+++) Enable the ADC IRQ handler using HAL_NVIC_EnableIRQ()
+             (+++) In ADC IRQ handler, call HAL_ADC_IRQHandler()
+      (##) In case of using DMA to control data transfer (e.g. HAL_ADC_Start_DMA())
+             (++) Enable the DMAx interface clock using __DMAx_CLK_ENABLE()
+             (++) Configure and enable two DMA streams stream for managing data
+                 transfer from peripheral to memory (output stream)
+             (++) 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.
+                       
+     (#) Configure the ADC Prescaler, conversion resolution and data alignment 
+         using the HAL_ADC_Init() function. 
+  
+     (#) Configure the ADC Injected channels group features, use HAL_ADC_Init()
+         and HAL_ADC_ConfigChannel() functions.
+         
+     (#) Three mode of operations are available within this driver :     
+  
+     *** Polling mode IO operation ***
+     =================================
+     [..]    
+       (+) Start the ADC peripheral using HAL_ADCEx_InjectedStart() 
+       (+) Wait for end of conversion using HAL_ADC_PollForConversion(), at this stage
+           user can specify the value of timeout according to his end application      
+       (+) To read the ADC converted values, use the HAL_ADCEx_InjectedGetValue() function.
+       (+) Stop the ADC peripheral using HAL_ADCEx_InjectedStop()
+  
+     *** Interrupt mode IO operation ***    
+     ===================================
+     [..]    
+       (+) Start the ADC peripheral using HAL_ADCEx_InjectedStart_IT() 
+       (+) Use HAL_ADC_IRQHandler() called under ADC_IRQHandler() Interrupt subroutine
+       (+) At ADC end of conversion HAL_ADCEx_InjectedConvCpltCallback() function is executed and user can 
+            add his own code by customization of function pointer HAL_ADCEx_InjectedConvCpltCallback 
+       (+) In case of ADC Error, HAL_ADCEx_InjectedErrorCallback() function is executed and user can 
+            add his own code by customization of function pointer HAL_ADCEx_InjectedErrorCallback
+       (+) Stop the ADC peripheral using HAL_ADCEx_InjectedStop_IT()
+       
+            
+     *** DMA mode IO operation ***    
+     ==============================
+     [..]    
+       (+) Start the ADC peripheral using HAL_ADCEx_InjectedStart_DMA(), at this stage the user specify the length 
+           of data to be transfered at each end of conversion 
+       (+) At The end of data transfer ba HAL_ADCEx_InjectedConvCpltCallback() function is executed and user can 
+            add his own code by customization of function pointer HAL_ADCEx_InjectedConvCpltCallback 
+       (+) In case of transfer Error, HAL_ADCEx_InjectedErrorCallback() function is executed and user can 
+            add his own code by customization of function pointer HAL_ADCEx_InjectedErrorCallback
+        (+) Stop the ADC peripheral using HAL_ADCEx_InjectedStop_DMA()
+        
+     *** Multi mode ADCs Regular channels configuration ***
+     ======================================================
+     [..]        
+       (+) Select the Multi mode ADC regular channels features (dual or triple mode)  
+          and configure the DMA mode using HAL_ADCEx_MultiModeConfigChannel() functions. 
+       (+) Start the ADC peripheral using HAL_ADCEx_MultiModeStart_DMA(), at this stage the user specify the length 
+           of data to be transfered at each end of conversion           
+       (+) Read the ADCs converted values using the HAL_ADCEx_MultiModeGetValue() function.

+  ==============================================================================
+    [..]            
+      (#) Enable the CAN controller interface clock using 
+          __CAN1_CLK_ENABLE() for CAN1 and __CAN1_CLK_ENABLE() for CAN2
+      -@- In case you are using CAN2 only, you have to enable the CAN1 clock.
+       
+      (#) CAN pins configuration
+        (++) Enable the clock for the CAN GPIOs using the following function:
+             __GPIOx_CLK_ENABLE()   
+        (++) Connect and configure the involved CAN pins to AF9 using the 
+              following function HAL_GPIO_Init() 
+              
+      (#) Initialise and configure the CAN using CAN_Init() function.   
+                 
+      (#) Transmit the desired CAN frame using HAL_CAN_Transmit() function.
+           
+      (#) Receive a CAN frame using HAL_CAN_Recieve() function.
+
+     *** Polling mode IO operation ***
+     =================================
+     [..]    
+       (+) Start the CAN peripheral transmission and wait the end of this operation 
+           using HAL_CAN_Transmit(), at this stage user can specify the value of timeout
+           according to his end application
+       (+) Start the CAN peripheral reception and wait the end of this operation 
+           using HAL_CAN_Receive(), at this stage user can specify the value of timeout
+           according to his end application 
+       
+     *** Interrupt mode IO operation ***    
+     ===================================
+     [..]    
+       (+) Start the CAN peripheral transmission using HAL_CAN_Transmit_IT()
+       (+) Start the CAN peripheral reception using HAL_CAN_Receive_IT()         
+       (+) Use HAL_CAN_IRQHandler() called under the used CAN Interrupt subroutine
+       (+) At CAN end of transmission HAL_CAN_TxCpltCallback() function is executed and user can 
+            add his own code by customization of function pointer HAL_CAN_TxCpltCallback 
+       (+) In case of CAN Error, HAL_CAN_ErrorCallback() function is executed and user can 
+            add his own code by customization of function pointer HAL_CAN_ErrorCallback
+ 
+     *** CAN HAL driver macros list ***
+     ============================================= 
+     [..]
+       Below the list of most used macros in CAN HAL driver.
+       
+      (+) __HAL_CAN_ENABLE_IT: Enable the specified CAN interrupts
+      (+) __HAL_CAN_DISABLE_IT: Disable the specified CAN interrupts
+      (+) __HAL_CAN_GET_IT_SOURCE: Check if the specified CAN interrupt source is enabled or disabled
+      (+) __HAL_CAN_CLEAR_FLAG: Clear the CAN's pending flags
+      (+) __HAL_CAN_GET_FLAG: Get the selected CAN's flag status
+      
+     [..] 
+      (@) You can refer to the CAN HAL driver header file for more useful macros

+    *** How to configure Systick using Cortex HAL driver ***
+    ========================================================
+    [..]
+    Setup SysTick Timer for 1 msec interrupts.
+           
+   (+) 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 (0x0F).
+        (++) 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 stm32f4xx_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

+
+      (#) Enable CRC AHB clock using __CRC_CLK_ENABLE();
+
+      (#) Use HAL_CRC_Accumulate() function to compute the CRC value of 
+          a 32-bit data buffer using combination of the previous CRC value
+          and the new one.
+
+      (#) Use HAL_CRC_Calculate() function to compute the CRC Value of 
+          a new 32-bit data buffer. This function resets the CRC computation  
+          unit before starting the computation to avoid getting wrong CRC values.

+  ==============================================================================
+                     ##### 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_CRYP_AESECB_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_CRYP_AESECB_Encrypt_DMA())
+             (++) Enable the DMAx interface clock using 
+                 (+++) __DMAx_CLK_ENABLE()
+             (++) Configure and enable two DMA streams one for managing data transfer from
+                 memory to peripheral (input stream) and another stream for managing data
+                 transfer from peripheral to memory (output stream)
+             (++) 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 key size: 128, 192 and 256. This parameter is relevant only for AES
+         (##) The encryption/decryption key. It's size depends on the algorithm
+              used for encryption/decryption
+         (##) 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   Extended CRYP HAL module driver
+  *          This file provides firmware functions to manage the following 
+  *          functionalities of CRYP extension peripheral:
+  *           + Extended AES processing functions     
+  *  
+  @verbatim
+  ==============================================================================
+                     ##### How to use this driver #####
+  ==============================================================================
+    [..]
+    The CRYP Extension 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_CRYPEx_AESGCM_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 DMAx interface clock using __DMAx_CLK_ENABLE()
+            (+++) Configure and enable two DMA streams one for managing data transfer from
+                memory to peripheral (input stream) and another stream for managing data
+                transfer from peripheral to memory (output stream)
+            (+++) 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() and 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 key size: 128, 192 and 256. This parameter is relevant only for AES
+        (##) The encryption/decryption key. Its size depends on the algorithm
+                used for encryption/decryption
+        (##) 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_CRYPEx_AESGCM_Encrypt()
+        (##) Interrupt mode: encryption and decryption APIs are not blocking functions
+                i.e. they process the data under interrupt
+                e.g. HAL_CRYPEx_AESGCM_Encrypt_IT()
+        (##) DMA mode: encryption and decryption APIs are not blocking functions
+                i.e. the data transfer is ensured by DMA
+                e.g. HAL_CRYPEx_AESGCM_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.
+    (#)In AES-GCM and AES-CCM modes are an authenticated encryption algorithms
+       which provide authentication messages.
+       HAL_AES_GCM_Finish() and HAL_AES_CCM_Finish() are used to provide those
+       authentication messages.
+       Call those functions after the processing ones (polling, interrupt or DMA).
+       e.g. in AES-CCM mode call HAL_CRYPEx_AESCCM_Encrypt() to encrypt the plain data
+            then call HAL_CRYPEx_AESCCM_Finish() to get the authentication message
+    (#)Call HAL_CRYP_DeInit() to deinitialize the CRYP peripheral.

+  ==============================================================================
+                      ##### DAC Peripheral features #####
+  ==============================================================================
+    [..]        
+      *** DAC Channels ***
+      ====================  
+    [..]  
+    The device integrates two 12-bit Digital Analog Converters that can 
+    be used independently or simultaneously (dual mode):
+      (#) DAC channel1 with DAC_OUT1 (PA4) as output
+      (#) DAC channel2 with DAC_OUT2 (PA5) 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, TIM4, TIM5, TIM6, TIM7 and TIM8 
+          (DAC_Trigger_T2_TRGO, DAC_Trigger_T4_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 
+         (#) Triangle wave
+            
+       *** 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 Stream5 channel7 which must be 
+             already configured
+         (#) DAC channel2 : mapped on DMA1 Stream6 channel7 which must be 
+             already configured
+       
+    -@- For Dual mode and specific signal (Triangle and noise) generation please 
+        refer to Extension Features Driver description        
+  
+      
+                      ##### 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, DAC_OUT2: PA5) 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
+
+     *** Polling mode IO operation ***
+     =================================
+     [..]    
+       (+) Start the DAC peripheral using HAL_DAC_Start() 
+       (+) To read the DAC last data output value value, use the HAL_DAC_GetValue() function.
+       (+) Stop the DAC peripheral using HAL_DAC_Stop()
+       
+     *** DMA mode IO operation ***    
+     ==============================
+     [..]    
+       (+) Start the DAC peripheral using HAL_DAC_Start_DMA(), at this stage the user specify the length 
+           of data to be transfered at each end of conversion 
+       (+) At The end of data transfer HAL_DAC_ConvCpltCallbackCh1()or HAL_DAC_ConvCpltCallbackCh2()  
+           function is executed and user can add his own code by customization of function pointer 
+           HAL_DAC_ConvCpltCallbackCh1 or HAL_DAC_ConvCpltCallbackCh2
+       (+) In case of transfer Error, HAL_DAC_ErrorCallbackCh1() function is executed and user can 
+            add his own code by customization of function pointer HAL_DAC_ErrorCallbackCh1
+       (+) Stop the DAC peripheral using HAL_DAC_Stop_DMA()
+                    
+     *** DAC HAL driver macros list ***
+     ============================================= 
+     [..]
+       Below the list of most used macros in DAC HAL driver.
+       
+      (+) __HAL_DAC_ENABLE : Enable the DAC peripheral
+      (+) __HAL_DAC_DISABLE : Disable the DAC peripheral
+      (+) __HAL_DAC_CLEAR_FLAG: Clear the DAC's pending flags
+      (+) __HAL_DAC_GET_FLAG: Get the selected DAC's flag status
+      
+     [..]
+      (@) You can refer to the DAC HAL driver header file for more useful macros

+                        ##### How to use this driver #####
+  ==============================================================================
+  [..]
+      The sequence below describes how to use this driver to capture image
+      from a camera module connected to the DCMI Interface.
+      This sequence does not take into account the configuration of the
+      camera module, which should be made before to configure and enable
+      the DCMI to capture images.
+
+    (#) Program the required configuration through following parameters:
+        horizontal and vertical polarity, pixel clock polarity, Capture Rate,
+        Synchronization Mode, code of the frame delimiter and data width 
+        using HAL_DCMI_Init() function.
+
+    (#) Configure the DMA2_Stream1 channel1 to transfer Data from DCMI DR
+        register to the destination memory buffer.
+
+    (#) Program the required configuration through following parameters:
+        DCMI mode, destination memory Buffer address and the data length 
+        and enable capture using HAL_DCMI_Start_DMA() function.
+
+    (#) Optionally, configure and Enable the CROP feature to select a rectangular
+        window from the received image using HAL_DCMI_ConfigCrop() 
+        and HAL_DCMI_EnableCROP() functions
+
+    (#) The capture can be stopped using the following HAL_DCMI_Stop() function.
+
+    (#) To control DCMI state you can use the following function : HAL_DCMI_GetState()
+
+     *** DCMI HAL driver macros list ***
+     ============================================= 
+     [..]
+       Below the list of most used macros in DCMI HAL driver.
+       
+      (+) __HAL_DCMI_ENABLE: Enable the DCMI peripheral.
+      (+) __HAL_DCMI_DISABLE: Disable the DCMI peripheral.
+      (+) __HAL_DCMI_GET_FLAG: Get the DCMI pending flags.
+      (+) __HAL_DCMI_CLEAR_FLAG: Clear the DCMI pending flags.
+      (+) __HAL_DCMI_ENABLE_IT: Enable the specified DCMI interrupts.
+      (+) __HAL_DCMI_DISABLE_IT: Disable the specified DCMI interrupts.
+      (+) __HAL_DCMI_GET_IT_SOURCE: Check whether the specified DCMI interrupt has occurred or not.
+ 
+     [..] 
+       (@) You can refer to the DCMI HAL driver header file for more useful macros

+  * @brief   DMA HAL module driver.
+  *    
+  *          This file provides firmware functions to manage the following 
+  *          functionalities of the Direct Memory Access (DMA) peripheral:
+  *           + Initialization and de-initialization functions
+  *           + IO operation functions
+  *           + Peripheral State and errors functions
+  @verbatim     
+  ==============================================================================      
+                        ##### How to use this driver #####
+  ============================================================================== 
+  [..]
+   (#) Enable and configure the peripheral to be connected to the DMA Stream
+       (except for internal SRAM/FLASH memories: no initialization is 
+       necessary) please refer to Reference manual for connection between peripherals
+       and DMA requests . 
+          
+   (#) For a given Stream, program the required configuration through the following parameters:   
+       Transfer Direction, Source and Destination data formats, 
+       Circular, Normal or peripheral flow control mode, Stream Priority level, 
+       Source and Destination Increment mode, FIFO mode and its Threshold (if needed), 
+       Burst mode for Source and/or Destination (if needed) 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.
+    
+     -@-   The FIFO is used mainly to reduce bus usage and to allow data packing/unpacking: it is
+           possible to set different Data Sizes for the Peripheral and the Memory (ie. you can set
+           Half-Word data size for the peripheral to access its data register and set Word data size
+           for the Memory to gain in access time. Each two half words will be packed and written in
+           a single access to a Word in the Memory).
+      
+     -@-   When FIFO is disabled, it is not allowed to configure different Data Sizes for Source
+           and Destination. In this case the Peripheral Data Size will be applied to both Source
+           and Destination.               
+  
+     *** DMA HAL driver macros list ***
+     ============================================= 
+     [..]
+       Below the list of most used macros in DMA HAL driver.
+       
+      (+) __HAL_DMA_ENABLE: Enable the specified DMA Stream.
+      (+) __HAL_DMA_DISABLE: Disable the specified DMA Stream.
+      (+) __HAL_DMA_GET_FS: Return the current DMA Stream FIFO filled level.
+      (+) __HAL_DMA_GET_FLAG: Get the DMA Stream pending flags.
+      (+) __HAL_DMA_CLEAR_FLAG: Clear the DMA Stream pending flags.
+      (+) __HAL_DMA_ENABLE_IT: Enable the specified DMA Stream interrupts.
+      (+) __HAL_DMA_DISABLE_IT: Disable the specified DMA Stream interrupts.
+      (+) __HAL_DMA_GET_IT_SOURCE: Check whether the specified DMA Stream interrupt has occurred or not. 
+     
+     [..] 
+      (@) You can refer to the DMA HAL driver header file for more useful macros

+                        ##### How to use this driver #####
+  ============================================================================== 
+    [..]
+      (#) Program the required configuration through following parameters:   
+          the Transfer Mode, the output color mode and the output offset using 
+          HAL_DMA2D_Init() function.
+
+      (#) Program the required configuration through following parameters:   
+          the input color mode, the input color, input alpha value, alpha mode 
+          and the input offset using HAL_DMA2D_ConfigLayer() function for foreground
+          or/and background layer.
+          
+     *** Polling mode IO operation ***
+     =================================   
+    [..]        
+       (+) Configure the pdata, Destination and data length and Enable 
+           the transfer using HAL_DMA2D_Start() 
+       (+) Wait for end of transfer using HAL_DMA2D_PollForTransfer(), at this stage
+           user can specify the value of timeout according to his end application.
+               
+     *** Interrupt mode IO operation ***    
+     ===================================
+     [..] 
+       (#) Configure the pdata, Destination and data length and Enable 
+           the transfer using HAL_DMA2D_Start_IT() 
+       (#) Use HAL_DMA2D_IRQHandler() called under DMA2D_IRQHandler() Interrupt subroutine
+       (#) At the end of data transfer HAL_DMA2D_IRQHandler() function is executed and user can 
+           add his own function by customization of function pointer XferCpltCallback and 
+           XferErrorCallback (i.e a member of DMA2D handle structure). 
+
+         -@-   In Register-to-Memory transfer mode, the pdata parameter is the register
+               color, in Memory-to-memory or memory-to-memory with pixel format
+               conversion the pdata is the source address and it is the color value 
+               for the A4 or A8 mode.
+
+         -@-   Configure the foreground source address, the background source address, 
+               the Destination and data length and Enable the transfer using 
+               HAL_DMA2D_BlendingStart() in polling mode and HAL_DMA2D_BlendingStart_IT()
+               in interrupt mode.
+               
+         -@-   HAL_DMA2D_BlendingStart() and HAL_DMA2D_BlendingStart_IT() functions
+               are used if the memory to memory with blending transfer mode is selected.
+                   
+      (#) Optionally, configure and enable the CLUT using HAL_DMA2D_ConfigCLUT()
+          HAL_DMA2D_EnableCLUT() functions.
+
+      (#) Optionally, configure and enable LineInterrupt using the following function:
+          HAL_DMA2D_ProgramLineEvent().
+   
+      (#) The transfer can be suspended, continued and aborted using the following
+          functions: HAL_DMA2D_Suspend(), HAL_DMA2D_Resume(), HAL_DMA2D_Abort().
+                     
+      (#) To control DMA2D state you can use the following function: HAL_DMA2D_GetState()                   
+
+     *** DMA2D HAL driver macros list ***

+  * @brief   DMA Extension HAL module driver
+  *         This file provides firmware functions to manage the following 
+  *         functionalities of the DMA Extension peripheral:

+  ==============================================================================
+                        ##### How to use this driver #####
+  ==============================================================================
+  [..]
+  The DMA Extension HAL driver can be used as follows:
+   (#) Start a multi buffer transfer using the HAL_DMA_MultiBufferStart() function
+       for polling mode or HAL_DMA_MultiBufferStart_IT() for interrupt mode.
+                   
+     -@-  In Memory-to-Memory transfer mode, Multi (Double) Buffer mode is not allowed.
+     -@-  When Multi (Double) Buffer mode is enabled the, transfer is circular by default.
+     -@-  In Multi (Double) buffer mode, it is possible to update the base address for 
+          the AHB memory port on-the-fly (DMA_SxM0AR or DMA_SxM1AR) when the stream is enabled.

+  * @brief   FLASH HAL module driver.
+  *          This file provides firmware functions to manage the following 
+  *          functionalities of the internal FLASH memory:
+  *           + Program operations functions

+  ==============================================================================
+                        ##### FLASH peripheral features #####
+  ==============================================================================
+           
+  [..] The Flash memory interface manages CPU AHB I-Code and D-Code accesses 
+       to the Flash memory. It implements the erase and program Flash memory operations 
+       and the read and write protection mechanisms.
+      
+  [..] The Flash memory interface accelerates code execution with a system of instruction
+       prefetch and cache lines. 
+
+  [..] The FLASH main features are:
+      (+) Flash memory read operations
+      (+) Flash memory program/erase operations
+      (+) Read / write protections
+      (+) Prefetch on I-Code
+      (+) 64 cache lines of 128 bits on I-Code
+      (+) 8 cache lines of 128 bits on D-Code
+      
+      
+                     ##### How to use this driver #####
+  ==============================================================================
+    [..]                             
+      This driver provides functions and macros to configure and program the FLASH 
+      memory of all STM32F4xx 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, word and double 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_SetErrorCode()          
+
+    [..] 
+      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 Instruction cache and the Data cache
+       (+) Reset the Instruction cache and the Data cache
+       (+) Enable/Disable the FLASH interrupts
+       (+) Monitor the FLASH flags status
+

+  ==============================================================================
+                   ##### Flash Extension features #####
+  ==============================================================================
+           
+  [..] Comparing to other previous devices, the FLASH interface for STM32F427xx/437xx and 
+       STM32F429xx/439xx devices contains the following additional features 
+       
+       (+) Capacity up to 2 Mbyte with dual bank architecture supporting read-while-write
+           capability (RWW)
+       (+) Dual bank memory organization       
+       (+) PCROP protection for all banks
+   
+                      ##### How to use this driver #####
+  ==============================================================================
+  [..] This driver provides functions to configure and program the FLASH memory 
+       of all STM32F427xx/437xx andSTM32F429xx/439xx devices. It includes
+      (#) FLASH Memory Erase functions: 
+           (++) Lock and Unlock the FLASH interface using HAL_FLASH_Unlock() and 
+                HAL_FLASH_Lock() functions
+           (++) Erase function: Erase sector, erase all sectors
+           (++) There is two mode of erase :
+             (+++) Polling Mode using HAL_FLASHEx_Erase()
+             (+++) Interrupt Mode using HAL_FLASHEx_Erase_IT()
+             
+      (#) Option Bytes Programming functions: Use HAL_FLASHEx_OBProgram() to :
+           (++) Set/Reset the write protection
+           (++) Set the Read protection Level
+           (++) Set the BOR level
+           (++) Program the user Option Bytes
+      (#) Advanced Option Bytes Programming functions: Use HAL_FLASHEx_AdvOBProgram() to :  
+       (++) Extended space (bank 2) erase function
+       (++) Full FLASH space (2 Mo) erase (bank 1 and bank 2)
+       (++) Dual Boot actrivation
+       (++) Write protection configuration for bank 2
+       (++) PCROP protection configuration and control for both banks

+  *          This file provides firmware functions to manage the following 
+  *          functionalities of the General Purpose Input/Output (GPIO) peripheral:

+  *           + 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 AHB clock using the following function: __GPIOx_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 HASH HAL driver can be used as follows:
+    (#)Initialize the HASH low level resources by implementing the HAL_HASH_MspInit():
+        (##) Enable the HASH interface clock using __HASH_CLK_ENABLE()
+        (##) In case of using processing APIs based on interrupts (e.g. HAL_HMAC_SHA1_Start_IT())
+            (+++) Configure the HASH interrupt priority using HAL_NVIC_SetPriority()
+            (+++) Enable the HASH IRQ handler using HAL_NVIC_EnableIRQ()
+            (+++) In HASH IRQ handler, call HAL_HASH_IRQHandler()
+        (##) In case of using DMA to control data transfer (e.g. HAL_HMAC_SHA1_Start_DMA())
+            (+++) Enable the DMAx interface clock using __DMAx_CLK_ENABLE()
+            (+++) Configure and enable one DMA stream one for managing data transfer from
+                memory to peripheral (input stream). Managing data transfer from
+                peripheral to memory can be performed only using CPU
+            (+++) Associate the initialized DMA handle to the HASH DMA handle
+                using  __HAL_LINKDMA()
+            (+++) Configure the priority and enable the NVIC for the transfer complete
+                interrupt on the DMA Stream using HAL_NVIC_SetPriority() and HAL_NVIC_EnableIRQ()
+    (#)Initialize the HASH HAL using HAL_HASH_Init(). This function configures mainly:
+        (##) The data type: 1-bit, 8-bit, 16-bit and 32-bit.
+        (##) For HMAC, the encryption key.
+        (##) For HMAC, the key size used for encryption.
+    (#)Three processing functions are available:
+        (##) Polling mode: processing APIs are blocking functions
+             i.e. they process the data and wait till the digest computation is finished
+             e.g. HAL_HASH_SHA1_Start()
+        (##) Interrupt mode: encryption and decryption APIs are not blocking functions
+                i.e. they process the data under interrupt
+                e.g. HAL_HASH_SHA1_Start_IT()
+        (##) DMA mode: processing APIs are not blocking functions and the CPU is
+             not used for data transfer i.e. the data transfer is ensured by DMA
+                e.g. HAL_HASH_SHA1_Start_DMA()
+    (#)When the processing function is called at first time after HAL_HASH_Init()
+       the HASH peripheral is initialized and processes the buffer in input.
+       After that, the digest computation is started.
+       When processing multi-buffer use the accumulate function to write the
+       data in the peripheral without starting the digest computation. In last 
+       buffer use the start function to input the last buffer ans start the digest
+       computation.
+       (##) e.g. HAL_HASH_SHA1_Accumulate() : write 1st data buffer in the peripheral without starting the digest computation
+       (##) write (n-1)th data buffer in the peripheral without starting the digest computation
+       (##) HAL_HASH_SHA1_Start() : write (n)th data buffer in the peripheral and start the digest computation
+    (#)In HMAC mode, there is no Accumulate API. Only Start API is available.
+    (#)In case of using DMA, call the DMA start processing e.g. HAL_HASH_SHA1_Start_DMA().
+       After that, call the finish function in order to get the digest value
+       e.g. HAL_HASH_SHA1_Finish()
+    (#)Call HAL_HASH_DeInit() to deinitialize the HASH peripheral.

+  *          functionalities of HASH peripheral:
+  *           + Extended HASH processing functions based on SHA224 Algorithm

+  @verbatim
+  ==============================================================================
+                     ##### How to use this driver #####
+  ==============================================================================
+    [..]
+    The HASH HAL driver can be used as follows:
+    (#)Initialize the HASH low level resources by implementing the HAL_HASH_MspInit():
+        (##) Enable the HASH interface clock using __HASH_CLK_ENABLE()
+        (##) In case of using processing APIs based on interrupts (e.g. HAL_HMACEx_SHA224_Start())
+            (+++) Configure the HASH interrupt priority using HAL_NVIC_SetPriority()
+            (+++) Enable the HASH IRQ handler using HAL_NVIC_EnableIRQ()
+            (+++) In HASH IRQ handler, call HAL_HASH_IRQHandler()
+        (##) In case of using DMA to control data transfer (e.g. HAL_HMACEx_SH224_Start_DMA())
+            (+++) Enable the DMAx interface clock using __DMAx_CLK_ENABLE()
+            (+++) Configure and enable one DMA stream one for managing data transfer from
+                memory to peripheral (input stream). Managing data transfer from
+                peripheral to memory can be performed only using CPU
+            (+++) Associate the initialized DMA handle to the HASH DMA handle
+                using  __HAL_LINKDMA()
+            (+++) Configure the priority and enable the NVIC for the transfer complete
+                interrupt on the DMA Stream: HAL_NVIC_SetPriority() and HAL_NVIC_EnableIRQ()
+    (#)Initialize the HASH HAL using HAL_HASH_Init(). This function configures mainly:
+        (##) The data type: 1-bit, 8-bit, 16-bit and 32-bit.
+        (##) For HMAC, the encryption key.
+        (##) For HMAC, the key size used for encryption.
+    (#)Three processing functions are available:
+        (##) Polling mode: processing APIs are blocking functions
+             i.e. they process the data and wait till the digest computation is finished
+             e.g. HAL_HASHEx_SHA224_Start()
+        (##) Interrupt mode: encryption and decryption APIs are not blocking functions
+                i.e. they process the data under interrupt
+                e.g. HAL_HASHEx_SHA224_Start_IT()
+        (##) DMA mode: processing APIs are not blocking functions and the CPU is
+             not used for data transfer i.e. the data transfer is ensured by DMA
+                e.g. HAL_HASHEx_SHA224_Start_DMA()
+    (#)When the processing function is called at first time after HAL_HASH_Init()
+       the HASH peripheral is initialized and processes the buffer in input.
+       After that, the digest computation is started.
+       When processing multi-buffer use the accumulate function to write the
+       data in the peripheral without starting the digest computation. In last 
+       buffer use the start function to input the last buffer ans start the digest
+       computation.
+       (##) e.g. HAL_HASHEx_SHA224_Accumulate() : write 1st data buffer in the peripheral without starting the digest computation
+       (##)  write (n-1)th data buffer in the peripheral without starting the digest computation
+       (##)  HAL_HASHEx_SHA224_Start() : write (n)th data buffer in the peripheral and start the digest computation
+    (#)In HMAC mode, there is no Accumulate API. Only Start API is available.
+    (#)In case of using DMA, call the DMA start processing e.g. HAL_HASHEx_SHA224_Start_DMA().
+       After that, call the finish function in order to get the digest value
+       e.g. HAL_HASHEx_SHA224_Finish()
+    (#)Call HAL_HASH_DeInit() to deinitialize the HASH peripheral.

+                        ##### 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 Speed, Duty cycle, Addressing mode, Own Address1,
+        Dual Addressing mode, Own Address2, 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 :

+ ===============================================================================
+                  ##### 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.
+   -@- Make sure that either:
+        (+@) I2S PLL is configured or 
+        (+@) External clock source is configured after setting correctly 
+             the define constant EXTERNAL_CLOCK_VALUE in the stm32f4xx_hal_conf.h file. 
+             
+   (#) Three mode of operations are available within this driver :

+            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 :

+  *          functionalities of I2S extension peripheral:
+  *           + Extension features Functions
+  *         
+  @verbatim
+  ==============================================================================
+                    ##### I2S Extension features #####
+  ============================================================================== 
+  [..]
+     (#) In I2S full duplex mode, each SPI peripheral is able to manage sending and receiving 
+         data simultaneously using two data lines. Each SPI peripheral has an extended block 
+         called I2Sxext ie. I2S2ext for SPI2 and I2S3ext for SPI3).
+     (#) The extension block is not a full SPI IP, it is used only as I2S slave to
+         implement full duplex mode. The extension block uses the same clock sources
+         as its master.
+
+     (#) Both I2Sx and I2Sx_ext can be configured as transmitters or receivers.
+
+     -@- Only I2Sx can deliver SCK and WS to I2Sx_ext in full duplex mode, where 
+         I2Sx can be I2S2 or I2S3.
+
+ ===============================================================================
+                  ##### How to use this driver #####
+ ===============================================================================
+ [..]    
+   Three mode of operations are available within this driver :

+     (+) Send and receive in the same time an amount of data in blocking mode using HAL_I2S_TransmitReceive() 
+   
+   *** Interrupt mode IO operation ***    
+   ===================================
+   [..]    
+     (+) Send and receive in the same time an amount of data in non blocking mode using HAL_I2S_TransmitReceive_IT() 
+     (+) At transmission end of half transfer HAL_I2S_TxHalfCpltCallback is executed and user can

+     (+) 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 and receive an amount of data in non blocking mode (DMA) using HAL_I2S_TransmitReceive_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

+  ==============================================================================
+                        ##### How to use this driver #####
+  ==============================================================================
+  [..]
+    The IRDA HAL driver can be used as follow:
+    
+    (#) Declare a IRDA_HandleTypeDef handle structure.
+    (#) Initialize the IRDA low level resources by implement 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 mode of operations 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

+    This subsection provides a set of functions allowing to initialize the USARTx or the UARTy 
+    in IrDA mode.
+      (+) For the asynchronous mode only these parameters can be configured: 
+        (++) BaudRate
+        (++) WordLength 
+        (++) 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 IRDA frame formats are as listed in the following table:
+   +-------------------------------------------------------------+     
+   |   M bit |  PCE bit  |            IRDA frame                 |

+   +-------------------------------------------------------------+            
+        (++) Prescaler: A pulse of width less than two and greater than one PSC period(s) may or may
+             not be rejected. The receiver set up time should be managed by software. The IrDA physical layer
+             specification specifies a minimum of 10 ms delay between transmission and 
+             reception (IrDA is a half duplex protocol).

+    This subsection provides a set of functions allowing to manage the IRDA data transfers.
+    [..]
+    IrDA is a half duplex communication protocol. If the Transmitter is busy, any data
+    on the IrDA receive line will be ignored by the IrDA decoder and if the Receiver 
+    is busy, data on the TX from the USART to IrDA will not be encoded by IrDA.
+    While receiving data, transmission should be avoided as the data to be transmitted
+    could be corrupted.
+
+    (#) 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

+  @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): ~125us / ~32.7s
+         The IWDG timeout may vary due to LSI frequency dispersion. STM32F4xx
+         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 #####
+  ==============================================================================
+    [..]
+      (+) Use IWDG using HAL_IWDG_Start() function to:
+          (++) Enable write access to IWDG_PR and IWDG_RLR registers.   
+          (++) Configure the IWDG prescaler and counter reload values.
+          (++) 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.  
+     
+     *** 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
+      (+) __HAL_IWDG_CLEAR_FLAG: Clear the IWDG's pending flags      
+

+  ==============================================================================
+                         ##### How to use this driver #####
+  ==============================================================================    
+    [..]
+      This driver is a generic layered driver which contains a set of APIs used to 
+      control NAND flash memories. It uses the FMC/FSMC layer functions to interface 
+      with NAND devices. This driver is used as follows:
+    
+      (+) NAND flash memory configuration sequence using the function HAL_NAND_Init() 
+          with control and timing parameters for both common and attribute spaces.
+            
+      (+) Read NAND flash memory maker and device IDs using the function
+          HAL_NAND_Read_ID(). The read information is stored in the NAND_ID_TypeDef 
+          structure declared by the function caller. 
+        
+      (+) Access NAND flash memory by read/write operations using the functions
+          HAL_NAND_Read_Page()/HAL_NAND_Read_SpareArea(), HAL_NAND_Write_Page()/HAL_NAND_Write_SpareArea()
+          to read/write page(s)/spare area(s). These functions use specific device 
+          information (Block, page size..) predefined by the user in the HAL_NAND_Info_TypeDef 
+          structure. The read/write address information is contained by the Nand_Address_Typedef
+          structure passed as parameter.
+        
+      (+) Perform NAND flash Reset chip operation using the function HAL_NAND_Reset().
+        
+      (+) Perform NAND flash erase block operation using the function HAL_NAND_Erase_Block().
+          The erase block address information is contained in the Nand_Address_Typedef 
+          structure passed as parameter.
+    
+      (+) Read the NAND flash status operation using the function HAL_NAND_Read_Status().
+        
+      (+) You can also control the NAND device by calling the control APIs HAL_NAND_ECC_Enable()/
+          HAL_NAND_ECC_Disable() to respectively enable/disable the ECC code correction
+          feature or the function HAL_NAND_GetECC() to get the ECC correction code. 
+       
+      (+) You can monitor the NAND device HAL state by calling the function
+          HAL_NAND_GetState()  
+
+    [..]
+      (@) This driver is a set of generic APIs which handle standard NAND flash operations.
+          If a NAND flash device contains different operations and/or implementations, 
+          it should be implemented separately.

+  * @brief   NOR HAL module driver.
+  *          This file provides a generic firmware to drive NOR memories mounted 
+  *          as external device.
+  *         
+  @verbatim
+  ==============================================================================
+                     ##### How to use this driver #####
+  ==============================================================================       
+    [..]
+      This driver is a generic layered driver which contains a set of APIs used to 
+      control NOR flash memories. It uses the FMC/FSMC layer functions to interface 
+      with NOR devices. This driver is used as follows:
+    
+      (+) NOR flash memory configuration sequence using the function HAL_NOR_Init() 
+          with control and timing parameters for both normal and extended mode.
+            
+      (+) Read NOR flash memory manufacturer code and device IDs using the function
+          HAL_NOR_Read_ID(). The read information is stored in the NOR_ID_TypeDef 
+          structure declared by the function caller. 
+        
+      (+) Access NOR flash memory by read/write data unit operations using the functions
+          HAL_NOR_Read(), HAL_NOR_Program().
+        
+      (+) Perform NOR flash erase block/chip operations using the functions 
+          HAL_NOR_Erase_Block() and HAL_NOR_Erase_Chip().
+        
+      (+) Read the NOR flash CFI (common flash interface) IDs using the function
+          HAL_NOR_Read_CFI(). The read information is stored in the NOR_CFI_TypeDef
+          structure declared by the function caller.
+        
+      (+) You can also control the NOR device by calling the control APIs HAL_NOR_WriteOperation_Enable()/
+          HAL_NOR_WriteOperation_Disable() to respectively enable/disable the NOR write operation  
+       
+      (+) You can monitor the NOR device HAL state by calling the function
+          HAL_NOR_GetState() 
+    [..]
+     (@) This driver is a set of generic APIs which handle standard NOR flash operations.
+         If a NOR flash device contains different operations and/or implementations, 
+         it should be implemented separately.
+
+     *** NOR HAL driver macros list ***
+     ============================================= 
+     [..]
+       Below the list of most used macros in NOR HAL driver.
+       
+      (+) __NOR_WRITE : NOR memory write data to specified address

+  * @brief   PCCARD HAL module driver.
+  *          This file provides a generic firmware to drive PCCARD memories mounted 
+  *          as external device.
+  *

+ ===============================================================================
+                        ##### How to use this driver #####
+ ===============================================================================  
+   [..]
+     This driver is a generic layered driver which contains a set of APIs used to 
+     control PCCARD/compact flash memories. It uses the FMC/FSMC layer functions 
+     to interface with PCCARD devices. This driver is used for:
+    
+    (+) PCCARD/compact flash memory configuration sequence using the function 
+        HAL_PCCARD_Init() with control and timing parameters for both common and 
+        attribute spaces.
+            
+    (+) Read PCCARD/compact flash memory maker and device IDs using the function
+        HAL_CF_Read_ID(). The read information is stored in the CompactFlash_ID 
+        structure declared by the function caller. 
+        
+    (+) Access PCCARD/compact flash memory by read/write operations using the functions
+        HAL_CF_Read_Sector()/HAL_CF_Write_Sector(), to read/write sector. 
+        
+    (+) Perform PCCARD/compact flash Reset chip operation using the function HAL_CF_Reset().
+        
+    (+) Perform PCCARD/compact flash erase sector operation using the function 
+        HAL_CF_Erase_Sector().
+    
+    (+) Read the PCCARD/compact flash status operation using the function HAL_CF_ReadStatus().
+     
+    (+) You can monitor the PCCARD/compact flash  device HAL state by calling the function
+        HAL_PCCARD_GetState()     
+        
+   [..]
+     (@) This driver is a set of generic APIs which handle standard PCCARD/compact flash 
+         operations. If a PCCARD/compact flash device contains different operations 
+         and/or implementations, it should be implemented separately.

+     (#) 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 
+              (+++) __OTGFS-OTG_CLK_ENABLE()/__OTGHS-OTG_CLK_ENABLE();
+              (+++) __OTGHSULPI_CLK_ENABLE(); (For High Speed Mode)
+           
+         (##) Initialize the related GPIO clocks
+         (##) Configure PCD pin-out
+         (##) Configure PCD NVIC interrupt
+    
+     (#)Associate the Upper USB device stack to the HAL PCD Driver:

+    *** 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).
+      (+) 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 is only one WakeUp pin: WakeUp Pin 1 on PA.00.
+
+    *** Low Power modes configuration ***
+    =====================================
+    [..]
+      The devices feature 3 low-power modes:
+      (+) Sleep mode: Cortex-M4 core stopped, peripherals kept running.
+      (+) Stop mode: all clocks are stopped, regulator running, regulator 
+          in low power mode
+      (+) Standby mode: 1.2V domain powered off.
+   
+   *** Sleep mode ***
+   ==================
+    [..]
+      (+) Entry:
+        The Sleep mode is entered by using the HAL_PWR_EnterSLEEPMode(PWR_MAINREGULATOR_ON, PWR_SLEEPENTRY_WFI)
+              functions with
+          (++) PWR_SLEEPENTRY_WFI: enter SLEEP mode with WFI instruction
+          (++) PWR_SLEEPENTRY_WFE: enter SLEEP mode with WFE instruction

+      -@@- The Regulator parameter is not used for the STM32F4 family 
+              and is kept as parameter just to maintain compatibility with the 
+              lower power families (STM32L).
+      (+) Exit:
+        Any peripheral interrupt acknowledged by the nested vectored interrupt 
+              controller (NVIC) can wake up the device from Sleep mode.
+
+   *** Stop mode ***
+   =================
+    [..]
+      In Stop mode, all clocks in the 1.2V domain are stopped, the PLL, the HSI,
+      and the HSE RC oscillators are disabled. Internal SRAM and register contents 
+      are preserved.
+      The voltage regulator can be configured either in normal or low-power mode.
+      To minimize the consumption In Stop mode, FLASH can be powered off before 
+      entering the Stop mode using the HAL_PWR_EnableFlashPowerDown() function.
+      It can be switched on again by software after exiting the Stop mode using
+      the HAL_PWR_DisableFlashPowerDown() function. 
+
+      (+) Entry:
+         The Stop mode is entered using the HAL_PWR_EnterSTOPMode(PWR_MAINREGULATOR_ON) 
+             function with:
+          (++) Main regulator ON.
+          (++) Low Power regulator ON.
+      (+) Exit:
+        Any EXTI Line (Internal or External) configured in Interrupt/Event mode.
+
+   *** Standby mode ***
+   ====================
+    [..]
+    (+)
+      The Standby mode allows to achieve the lowest power consumption. It is based 
+      on the Cortex-M4 deep sleep mode, with the voltage regulator disabled. 
+      The 1.2V domain is consequently powered off. The PLL, 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, backup SRAM and Standby 
+      circuitry.
+   
+      The voltage regulator is OFF.
+      
+      (++) 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 or a time-stamp event, without depending on 
+      an external interrupt (Auto-wakeup mode).
+
+      (+) RTC auto-wakeup (AWU) from the Stop and Standby modes
+       
+        (++) To wake up from the Stop mode with an RTC alarm event, it is necessary to 
+              configure the RTC to generate the RTC alarm using the HAL_RTC_SetAlarm_IT() function.
+
+        (++) To wake up from the Stop mode with an RTC Tamper or time stamp event, it 
+             is necessary to configure the RTC to detect the tamper or time stamp event using the
+                HAL_RTCEx_SetTimeStamp_IT() or HAL_RTCEx_SetTamper_IT() functions.
+                  
+        (++) To wake up from the Stop mode with an RTC WakeUp event, it is necessary to
+              configure the RTC to generate the RTC WakeUp event using the HAL_RTCEx_SetWakeUpTimer_IT() function.

+ ===============================================================================
+                 ##### Peripheral extended features functions #####
+ ===============================================================================
+
+    *** Main and Backup Regulators configuration ***
+    ================================================
+    [..] 
+      (+) The backup domain includes 4 Kbytes of backup SRAM accessible only from 
+          the CPU, and address in 32-bit, 16-bit or 8-bit mode. Its content is 
+          retained even in Standby or VBAT mode when the low power backup regulator
+          is enabled. It can be considered as an internal EEPROM when VBAT is 
+          always present. You can use the HAL_PWR_EnableBkUpReg() function to 
+          enable the low power backup regulator. 
+
+      (+) When the backup domain is supplied by VDD (analog switch connected to VDD) 
+          the backup SRAM is powered from VDD which replaces the VBAT power supply to 
+          save battery life.
+
+      (+) The backup SRAM is not mass erased by a tamper event. It is read 
+          protected to prevent confidential data, such as cryptographic private 
+          key, from being accessed. The backup SRAM can be erased only through 
+          the Flash interface when a protection level change from level 1 to 
+          level 0 is requested. 
+      -@- Refer to the description of Read protection (RDP) in the Flash 
+          programming manual.
+
+      (+) 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_MAINREGULATORMODE_CONFIG() 
+          macro which configure VOS bit in PWR_CR register
+          
+        Refer to the product datasheets for more details.
+
+    *** FLASH Power Down configuration ****
+    =======================================
+    [..] 
+      (+) By setting the FPDS bit in the PWR_CR register by using the 
+          HAL_PWR_EnableFlashPowerDown() function, the Flash memory also enters power 
+          down mode when the device enters Stop mode. When the Flash memory 
+          is in power down mode, an additional startup delay is incurred when 
+          waking up from Stop mode.
+          
+           (+) For STM32F42xxx/43xxx Devices, the scale can be modified only when the PLL 
+           is OFF and the HSI or HSE clock source is selected as system clock. 
+           The new value programmed is active only when the PLL is ON.
+           When the PLL is OFF, the voltage scale 3 is automatically selected. 
+        Refer to the datasheets for more details.
+
+    *** Over-Drive and Under-Drive configuration ****
+    =================================================
+    [..]         
+       (+) For STM32F42xxx/43xxx Devices, in Run mode: the main regulator has
+           2 operating modes available:
+        (++) Normal mode: The CPU and core logic operate at maximum frequency at a given 
+             voltage scaling (scale 1, scale 2 or scale 3)
+        (++) Over-drive mode: This mode allows the CPU and the core logic to operate at a 
+            higher frequency than the normal mode for a given voltage scaling (scale 1,  
+            scale 2 or scale 3). This mode is enabled through HAL_PWREx_EnableOverDrive() function and
+            disabled by HAL_PWREx_DisableOverDrive() function, to enter or exit from Over-drive mode please follow 
+            the sequence described in Reference manual.
+             
+       (+) For STM32F42xxx/43xxx Devices, in Stop mode: the main regulator or low power regulator 
+           supplies a low power voltage to the 1.2V domain, thus preserving the content of registers 
+           and internal SRAM. 2 operating modes are available:
+         (++) Normal mode: the 1.2V domain is preserved in nominal leakage mode. This mode is only 
+              available when the main regulator or the low power regulator is used in Scale 3 or 
+              low voltage mode.
+         (++) Under-drive mode: the 1.2V domain is preserved in reduced leakage mode. This mode is only
+              available when the main regulator or the low power regulator is in low voltage mode.

+    [..]  
+      After reset the device is running from Internal High Speed oscillator 
+      (HSI 16MHz) with Flash 0 wait state, Flash prefetch buffer, D-Cache 
+      and I-Cache are disabled, and all peripherals are off except internal
+      SRAM, Flash and JTAG.
+      (+) There is no prescaler on High speed (AHB) and Low speed (APB) busses;
+          all peripherals mapped on these busses are running at HSI speed.
+      (+) The clock for all peripherals is switched off, except the SRAM and FLASH.
+      (+) All GPIOs are in input floating state, except the JTAG 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

+      This section provide functions allowing to configure the internal/external oscillators
+      (HSE, HSI, LSE, LSI, PLL, CSS and MCO) and the System busses clocks (SYSCLK, AHB, APB1 
+       and APB2).
+
+    [..] 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.
+
+         (#) LSI (low-speed internal), 32 KHz low consumption RC used as IWDG and/or RTC
+             clock source.
+
+         (#) HSE (high-speed external), 4 to 26 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), featuring two different output clocks:
+           (++) The first output is used to generate the high speed system clock (up to 168 MHz)
+           (++) The second output is used to generate the clock for the USB OTG FS (48 MHz),
+                the random analog generator (<=48 MHz) and the SDIO (<= 48 MHz).
+
+         (#) CSS (Clock security system), once enable using the macro __HAL_RCC_CSS_ENABLE()
+             and if a HSE clock failure occurs(HSE used directly or through PLL as System 
+             clock source), the System clockis automatically switched to HSI and an interrupt
+             is generated if enabled. The interrupt is linked to the Cortex-M4 NMI 
+             (Non-Maskable Interrupt) exception vector.   
+
+         (#) MCO1 (microcontroller clock output), used to output HSI, LSE, HSE or PLL
+             clock (through a configurable prescaler) on PA8 pin.
+
+         (#) MCO2 (microcontroller clock output), used to output HSE, PLL, SYSCLK or PLLI2S
+             clock (through a configurable prescaler) on PC9 pin.
+
+    [..] System, AHB and APB busses clocks configuration  
+         (#) Several clock sources can be used to drive the System clock (SYSCLK): 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 AHB bus (DMA, GPIO...). 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 either from a specific PLL (PLLI2S) or
+                from an external clock mapped on the I2S_CKIN pin. 
+                You have to use __HAL_RCC_PLLI2S_CONFIG() macro to configure this clock.
+          (+@) SAI: the SAI clock can be derived either from a specific PLL (PLLI2S) or (PLLSAI) or
+                from an external clock mapped on the I2S_CKIN pin. 
+                You have to use __HAL_RCC_PLLI2S_CONFIG() macro to configure this clock. 
+           (+@) RTC: the RTC clock can be derived either from the LSI, LSE or HSE clock
+                divided by 2 to 31. You have to use __HAL_RCC_RTC_CONFIG() and __HAL_RCC_RTC_ENABLE()
+                macros to configure this clock. 
+           (+@) USB OTG FS, SDIO and RTC: USB OTG FS require a frequency equal to 48 MHz
+                to work correctly, while the SDIO require a frequency equal or lower than
+                to 48. This clock is derived of the main PLL through PLLQ divider.
+           (+@) IWDG clock which is always the LSI clock.
+       
+         (#) For the STM32F405xx/07xx and STM32F415xx/17xx devices, the maximum
+             frequency of the SYSCLK and HCLK is 168 MHz, PCLK2 84 MHz and PCLK1 42 MHz.

+  @verbatim
+  ==============================================================================
+              ##### Backup Domain Operating Condition #####
+  ==============================================================================
+  [..] The real-time clock (RTC), the RTC backup registers, and the backup 
+       SRAM (BKP SRAM) can be powered from the VBAT voltage when the main 
+       VDD supply is powered off.
+       To retain the content of the RTC backup registers, backup SRAM, and supply 
+       the RTC when VDD is turned off, VBAT pin can be connected to an optional 
+       standby voltage supplied by a battery or by another source.
+
+  [..] To allow the RTC to operate even when the main digital supply (VDD) is turned
+       off, the VBAT pin powers the following blocks:
+    (#) The RTC
+    (#) The LSE oscillator
+    (#) The backup SRAM when the low power backup regulator is enabled
+    (#) PC13 to PC15 I/Os, plus PI8 I/O (when available)
+  
+  [..] When the backup domain is supplied by VDD (analog switch connected to VDD),
+       the following functions are available:
+    (#) PC14 and PC15 can be used as either GPIO or LSE pins
+    (#) PC13 can be used as a GPIO or as the RTC_AF1 pin
+    (#) PI8 can be used as a GPIO or as the RTC_AF2 pin
+  
+  [..] When the backup domain is supplied by VBAT (analog switch connected to VBAT 
+       because VDD is not present), the following functions are available:
+    (#) PC14 and PC15 can be used as LSE pins only
+    (#) PC13 can be used as the RTC_AF1 pin 
+    (#) PI8 can be used as the RTC_AF2 pin
+             
+                   ##### Backup Domain Reset #####
+  ==================================================================
+  [..] The backup domain reset sets all RTC registers and the RCC_BDCR register 
+       to their reset values. The BKPSRAM is not affected by this reset. The only
+       way of resetting the BKPSRAM is through the Flash interface by requesting 
+       a protection level change from 1 to 0.
+  [..] A backup domain reset is generated when one of the following events occurs:
+    (#) Software reset, triggered by setting the BDRST bit in the 
+        RCC Backup domain control register (RCC_BDCR). 
+    (#) VDD or VBAT power on, if both supplies have previously been powered off.  
+
+                   ##### Backup Domain Access #####
+  ==================================================================
+  [..] After reset, the backup domain (RTC registers, RTC backup data 
+       registers and backup SRAM) 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 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 provide functions allowing to initialize and configure the

+         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 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   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
+  ==============================================================================
+                  ##### 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.
+  
+  *** 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.
+  
+  *** TimeStamp configuration ***
+  ===============================
+  [..]
+    (+) Configure the RTC_AFx trigger and 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.
+    (+) The TIMESTAMP alternate function can be mapped either to RTC_AF1 (PC13)
+        or RTC_AF2 (PI8) depending on the value of TSINSEL bit in 
+        RTC_TAFCR register. The corresponding pin is also selected by HAL_RTC_SetTimeStamp()
+        or HAL_RTC_SetTimeStamp_IT() 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, 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 TAMPER1 alternate function can be mapped either to RTC_AF1 (PC13)
+        or RTC_AF2 (PI8) depending on the value of TAMP1INSEL bit in 
+        RTC_TAFCR register. The corresponding pin is also selected by HAL_RTC_SetTamper()
+        or HAL_RTC_SetTamper_IT() function.
+  
+  *** 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.

+ ==============================================================================
+                  ##### How to use this driver #####
+  ==============================================================================
+           
+  [..]
+    The SAI HAL driver can be used as follow:
+    
+    (#) Declare a SAI_HandleTypeDef handle structure.
+    (#) Initialize the SAI low level resources by implement the HAL_SAI_MspInit() API:
+        (##) Enable the SAI interface clock.                      
+        (##) SAI pins configuration:
+            (+++) Enable the clock for the SAI GPIOs.
+            (+++) Configure these SAI pins as alternate function pull-up.
+        (##) NVIC configuration if you need to use interrupt process (HAL_SAI_Transmit_IT()
+             and HAL_SAI_Receive_IT() APIs):
+            (+++) Configure the SAI interrupt priority.
+            (+++) Enable the NVIC SAI IRQ handle.
+
+        (##) DMA Configuration if you need to use DMA process (HAL_SAI_Transmit_DMA()
+             and HAL_SAI_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 SAI DMA Tx/Rx handle.
+            (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the 
+                DMA Tx/Rx Stream.
+  
+   (#) Program the SAI Mode, Standard, Data Format, MCLK Output, Audio frequency and Polarity
+       using HAL_SAI_Init() function.
+   
+   -@- The specific SAI interrupts (FIFO request and Overrun underrun interrupt)
+       will be managed using the macros __SAI_ENABLE_IT() and __SAI_DISABLE_IT()
+       inside the transmit and receive process.   
+       
+  [..]           
+   (@) Make sure that either:
+       (+@) I2S PLL is configured or 
+       (+@) SAI PLL is configured or 
+       (+@) External clock source is configured after setting correctly 
+            the define constant EXTERNAL_CLOCK_VALUE in the stm32f4xx_hal_conf.h file. 
+                        
+  [..]           
+    (@) In master TX mode: enabling the audio block immediately generates the bit clock 
+        for the external slaves even if there is no data in the FIFO, However FS signal 
+        generation is conditioned by the presence of data in the FIFO.
+                 
+  [..]           
+    (@) In master RX mode: enabling the audio block immediately generates the bit clock 
+        and FS signal for the external slaves. 
+                
+  [..]           
+    (@) It is mandatory to respect the following conditions in order to avoid bad SAI behavior: 
+        (+@)  First bit Offset <= (SLOT size - Data size)
+        (+@)  Data size <= SLOT size
+        (+@)  Number of SLOT x SLOT size = Frame length
+        (+@)  The number of slots should be even when SAI_FS_CHANNEL_IDENTIFICATION is selected.  
+
+  [..]         
+     Three mode of operations are available within this driver :     
+  
+   *** Polling mode IO operation ***
+   =================================
+   [..]    
+     (+) Send an amount of data in blocking mode using HAL_SAI_Transmit() 
+     (+) Receive an amount of data in blocking mode using HAL_SAI_Receive()
+   
+   *** Interrupt mode IO operation ***    
+   ===================================
+   [..]    
+     (+) Send an amount of data in non blocking mode using HAL_SAI_Transmit_IT() 
+     (+) At transmission end of transfer HAL_SAI_TxCpltCallback is executed and user can 
+         add his own code by customization of function pointer HAL_SAI_TxCpltCallback
+     (+) Receive an amount of data in non blocking mode using HAL_SAI_Receive_IT() 
+     (+) At reception end of transfer HAL_SAI_RxCpltCallback is executed and user can 
+         add his own code by customization of function pointer HAL_SAI_RxCpltCallback                                      
+     (+) In case of transfer Error, HAL_SAI_ErrorCallback() function is executed and user can 
+         add his own code by customization of function pointer HAL_SAI_ErrorCallback
+
+   *** DMA mode IO operation ***    
+   ==============================
+   [..] 
+     (+) Send an amount of data in non blocking mode (DMA) using HAL_SAI_Transmit_DMA() 
+     (+) At transmission end of transfer HAL_SAI_TxCpltCallback is executed and user can 
+         add his own code by customization of function pointer HAL_SAI_TxCpltCallback
+     (+) Receive an amount of data in non blocking mode (DMA) using HAL_SAI_Receive_DMA() 
+     (+) At reception end of transfer HAL_SAI_RxCpltCallback is executed and user can 
+         add his own code by customization of function pointer HAL_SAI_RxCpltCallback                                  
+     (+) In case of transfer Error, HAL_SAI_ErrorCallback() function is executed and user can 
+         add his own code by customization of function pointer HAL_SAI_ErrorCallback
+     (+) Pause the DMA Transfer using HAL_SAI_DMAPause()      
+     (+) Resume the DMA Transfer using HAL_SAI_DMAResume()  
+     (+) Stop the DMA Transfer using HAL_SAI_DMAStop()      
+   
+   *** SAI HAL driver macros list ***
+   ============================================= 
+   [..]
+     Below the list of most used macros in USART HAL driver.
+       
+      (+) __HAL_SAI_ENABLE: Enable the SAI peripheral
+      (+) __HAL_SAI_DISABLE: Disable the SAI peripheral
+      (+) __HAL_SAI_ENABLE_IT : Enable the specified SAI interrupts
+      (+) __HAL_SAI_DISABLE_IT : Disable the specified SAI interrupts
+      (+) __HAL_SAI_GET_IT_SOURCE: Check if the specified SAI interrupt source is 
+          enabled or disabled
+      (+) __HAL_SAI_GET_FLAG: Check whether the specified SAI flag is set or not

+    This subsection provides a set of functions allowing to manage the SAI 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 SAI IRQ when using Interrupt mode or the DMA IRQ when 
+            using DMA mode.
+
+    (+) Blocking mode functions are :
+        (++) HAL_SAI_Transmit()
+        (++) HAL_SAI_Receive()
+        (++) HAL_SAI_TransmitReceive()
+        
+    (+) No-Blocking mode functions with Interrupt are :
+        (++) HAL_SAI_Transmit_IT()
+        (++) HAL_SAI_Receive_IT()
+        (++) HAL_SAI_TransmitReceive_IT()
+
+    (+) No-Blocking mode functions with DMA are :
+        (++) HAL_SAI_Transmit_DMA()
+        (++) HAL_SAI_Receive_DMA()
+        (++) HAL_SAI_TransmitReceive_DMA()
+
+    (+) A set of Transfer Complete Callbacks are provided in No_Blocking mode:
+        (++) HAL_SAI_TxCpltCallback()
+        (++) HAL_SAI_RxCpltCallback()
+        (++) HAL_SAI_ErrorCallback()

+  ==============================================================================
+                        ##### How to use this driver #####
+  ==============================================================================
+  [..]
+    This driver implements a high level communication layer for read and write from/to 
+    this memory. The needed STM32 hardware resources (SDIO and GPIO) are performed by 
+    the user in HAL_SD_MspInit() function (MSP layer).                             
+    Basically, the MSP layer configuration should be the same as we provide in the 
+    examples.
+    You can easily tailor this configuration according to hardware resources.
+
+  [..]
+    This driver is a generic layered driver for SDIO memories which uses the HAL 
+    SDIO driver functions to interface with SD and uSD cards devices. 
+    It is used as follows:
+ 
+    (#)Initialize the SDIO low level resources by implement the HAL_SD_MspInit() API:
+        (##) Enable the SDIO interface clock using __SDIO_CLK_ENABLE(); 
+        (##) SDIO pins configuration for SD card
+            (+++) Enable the clock for the SDIO GPIOs using the functions __GPIOx_CLK_ENABLE();   
+            (+++) Configure these SDIO pins as alternate function pull-up using HAL_GPIO_Init()
+                  and according to your pin assignment;
+        (##) DMA Configuration if you need to use DMA process (HAL_SD_ReadBlocks_DMA()
+             and HAL_SD_WriteBlocks_DMA() APIs).
+            (+++) Enable the DMAx interface clock using __DMAx_CLK_ENABLE(); 
+            (+++) Configure the DMA using the function HAL_DMA_Init() with predeclared and filled. 
+        (##) NVIC configuration if you need to use interrupt process when using DMA transfer.
+            (+++) Configure the SDIO and DMA interrupt priorities using functions
+                  HAL_NVIC_SetPriority(); DMA priority is superior to SDIO's priority
+            (+++) Enable the NVIC DMA and SDIO IRQs using function HAL_NVIC_EnableIRQ()
+            (+++) SDIO interrupts are managed using the macros __HAL_SD_SDIO_ENABLE_IT() 
+                  and __HAL_SD_SDIO_DISABLE_IT() inside the communication process.
+            (+++) SDIO interrupts pending bits are managed using the macros __HAL_SD_SDIO_GET_IT()
+                  and __HAL_SD_SDIO_CLEAR_IT()
+    (#) At this stage, you can perform SD read/write/erase operations after SD card initialization  
+
+         
+  *** SD Card Initialization and configuration ***
+  ================================================    
+  [..]
+    To initialize the SD Card, use the HAL_SD_Init() function.  It Initializes 
+    the SD Card and put it into StandBy State (Ready for data transfer). 
+    This function provide the following operations:
+  
+    (#) Apply the SD Card initialization process at 400KHz and check the SD Card 
+        type (Standard Capacity or High Capacity). You can change or adapt this 
+        frequency by adjusting the "ClockDiv" field. 
+        The SD Card frequency (SDIO_CK) is computed as follows:
+  
+           SDIO_CK = SDIOCLK / (ClockDiv + 2)
+  
+        In initialization mode and according to the SD Card standard, 
+        make sure that the SDIO_CK frequency doesn't exceed 400KHz.
+  
+    (#) Get the SD CID and CSD data. All these information are managed by the SDCardInfo 
+        structure. This structure provide also ready computed SD Card capacity 
+        and Block size.
+        
+        -@- These information are stored in SD handle structure in case of future use.  
+  
+    (#) Configure the SD Card Data transfer frequency. By Default, the card transfer 
+        frequency is set to 24MHz. You can change or adapt this frequency by adjusting 
+        the "ClockDiv" field.
+        The SD Card frequency (SDIO_CK) is computed as follows:
+
+           SDIO_CK = SDIOCLK / (ClockDiv + 2) 
+
+        In transfer mode and according to the SD Card standard, make sure that the 
+        SDIO_CK frequency doesn't exceed 25MHz and 50MHz in High-speed mode switch.
+        To be able to use a frequency higher than 24MHz, you should use the SDIO 
+        peripheral in bypass mode. Refer to the corresponding reference manual 
+        for more details.
+  
+    (#) Select the corresponding SD Card according to the address read with the step 2.
+    
+    (#) Configure the SD Card in wide bus mode: 4-bits data.
+  
+  *** SD Card Read operation ***
+  ==============================
+  [..] 
+    (+) You can read from SD card in polling mode by using function HAL_SD_ReadBlocks(). 
+        This function support only 512-byte block length (the block size should be 
+        chosen as 512 byte).
+        You can choose either one block read operation or multiple block read operation 
+        by adjusting the "NumberOfBlocks" parameter.
+
+    (+) You can read from SD card in DMA mode by using function HAL_SD_ReadBlocks_DMA().
+        This function support only 512-byte block length (the block size should be 
+        chosen as 512 byte).
+        You can choose either one block read operation or multiple block read operation 
+        by adjusting the "NumberOfBlocks" parameter.
+        After this, you have to call the function HAL_SD_CheckReadOperation(), to insure
+        that the read transfer is done correctly in both DMA and SD sides.
+  
+  *** SD Card Write operation ***
+  =============================== 
+  [..] 
+    (+) You can write to SD card in polling mode by using function HAL_SD_WriteBlocks(). 
+        This function support only 512-byte block length (the block size should be 
+        chosen as 512 byte).
+        You can choose either one block read operation or multiple block read operation 
+        by adjusting the "NumberOfBlocks" parameter.
+
+    (+) You can write to SD card in DMA mode by using function HAL_SD_WriteBlocks_DMA().
+        This function support only 512-byte block length (the block size should be 
+        chosen as 512 byte).
+        You can choose either one block read operation or multiple block read operation 
+        by adjusting the "NumberOfBlocks" parameter.
+        After this, you have to call the function HAL_SD_CheckWriteOperation(), to insure
+        that the write transfer is done correctly in both DMA and SD sides.  
+  
+  *** SD card status ***
+  ====================== 
+  [..]
+    (+) At any time, you can check the SD Card status and get the SD card state 
+        by using the HAL_SD_GetStatus() function. This function checks first if the 
+        SD card is still connected and then get the internal SD Card transfer state.     
+    (+) You can also get the SD card SD Status register by using the HAL_SD_SendSDStatus() 
+        function.    
+
+  *** SD HAL driver macros list ***
+  ==================================
+  [..]
+    Below the list of most used macros in SD HAL driver.
+       
+    (+) __HAL_SD_SDIO_ENABLE : Enable the SD device
+    (+) __HAL_SD_SDIO_DISABLE : Disable the SD device

+                       ##### How to use this driver #####
+  ============================================================================== 
+  [..]
+    This driver is a generic layered driver which contains a set of APIs used to 
+    control SDRAM memories. It uses the FMC layer functions to interface 
+    with SDRAM devices.  
+    The following sequence should be followed to configure the FMC to interface
+    with SDRAM memories: 
+      
+   (#) Declare a SDRAM_HandleTypeDef handle structure, for example:
+          SDRAM_HandleTypeDef  hdsram; and: 
+          
+       (++) Fill the SDRAM_HandleTypeDef handle "Init" field with the allowed 
+            values of the structure member.
+            
+       (++) Fill the SDRAM_HandleTypeDef handle "Instance" field with a predefined 
+            base register instance for NOR or SDRAM device 
+             
+   (#) Declare a FMC_SDRAM_TimingTypeDef structure; for example:
+          FMC_SDRAM_TimingTypeDef  Timing;
+      and fill its fields with the allowed values of the structure member.
+      
+   (#) Initialize the SDRAM Controller by calling the function HAL_SDRAM_Init(). This function
+       performs the following sequence:
+          
+       (##) MSP hardware layer configuration using the function HAL_SDRAM_MspInit()
+       (##) Control register configuration using the FMC SDRAM interface function 
+            FMC_SDRAM_Init()
+       (##) Timing register configuration using the FMC SDRAM interface function 
+            FMC_SDRAM_Timing_Init()
+       (##) Program the SDRAM external device by applying its initialization sequence
+            according to the device plugged in your hardware. This step is mandatory
+            for accessing the SDRAM device.   
+
+   (#) At this stage you can perform read/write accesses from/to the memory connected 
+       to the SDRAM Bank. You can perform either polling or DMA transfer using the
+       following APIs:
+       (++) HAL_SDRAM_Read()/HAL_SDRAM_Write() for polling read/write access
+       (++) HAL_SDRAM_Read_DMA()/HAL_SDRAM_Write_DMA() for DMA read/write transfer
+       
+   (#) You can also control the SDRAM device by calling the control APIs HAL_SDRAM_WriteOperation_Enable()/
+       HAL_SDRAM_WriteOperation_Disable() to respectively enable/disable the SDRAM write operation or 
+       the function HAL_SDRAM_SendCommand() to send a specified command to the SDRAM
+       device. The command to be sent must be configured with the FMC_SDRAM_CommandTypeDef 
+       structure.   
+       
+   (#) You can continuously monitor the SDRAM device HAL state by calling the function
+       HAL_SDRAM_GetState()

+  ==============================================================================
+                     ##### How to use this driver #####
+  ==============================================================================
+    [..]
+      The SMARTCARD HAL driver can be used as follow:
+    
+    (#) Declare a SMARTCARD_HandleTypeDef handle structure.
+    (#) Initialize the SMARTCARD low level resources by implement the HAL_SMARTCARD_MspInit ()API:
+        (##) Enable the USARTx interface clock.
+        (##) SMARTCARD pins configuration:
+            (+++) Enable the clock for the SMARTCARD GPIOs.
+            (+++) Configure these SMARTCARD 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 SMARTCARD interrupts (Transmission complete interrupt, 
+             RXNE interrupt and Error Interrupts) will be managed using the macros
+             __SMARTCARD_ENABLE_IT() and __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 initilalized 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, Word Length , Stop Bit, Parity, Hardware 
+        flow control and Mode(Receiver/Transmitter) in the hsc Init structure.
+
+    (#) Initialize the SMARTCARD registers by calling the HAL_SMARTCARD_Init() API:
+        (++) These API's configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
+             by calling the customed HAL_SMARTCARD_MspInit(&hsc) API.
+             
+    (#) Three mode of operations are available within this driver :     
+  
+    *** Polling mode IO operation ***
+    =================================
+    [..]    
+      (+) Send an amount of data in blocking mode using HAL_SMARTCARD_Transmit()

+       
+    *** Interrupt mode IO operation ***    
+    ===================================
+    [..]    
+      (+) Send an amount of data in non blocking mode using HAL_SMARTCARD_Transmit_IT() 
+      (+) At transmission end of transfer HAL_SMARTCARD_TxCpltCallback is executed and user can 
+          add his own code by customization of function pointer HAL_SMARTCARD_TxCpltCallback
+      (+) Receive an amount of data in non blocking mode using HAL_SMARTCARD_Receive_IT() 
+      (+) At reception end of transfer HAL_SMARTCARD_RxCpltCallback is executed and user can 
+          add his own code by customization of function pointer HAL_SMARTCARD_RxCpltCallback
+      (+) In case of transfer Error, HAL_SMARTCARD_ErrorCallback() function is executed and user can 
+          add his own code by customization of function pointer HAL_SMARTCARD_ErrorCallback
+
+    *** DMA mode IO operation ***    
+    ==============================
+    [..] 
+      (+) Send an amount of data in non blocking mode (DMA) using HAL_SMARTCARD_Transmit_DMA() 
+      (+) At transmission end of transfer HAL_SMARTCARD_TxCpltCallback is executed and user can 
+          add his own code by customization of function pointer HAL_SMARTCARD_TxCpltCallback
+      (+) Receive an amount of data in non blocking mode (DMA) using HAL_SMARTCARD_Receive_DMA() 
+      (+) At reception end of transfer HAL_SMARTCARD_RxCpltCallback is executed and user can 
+          add his own code by customization of function pointer HAL_SMARTCARD_RxCpltCallback
+      (+) In case of transfer Error, HAL_SMARTCARD_ErrorCallback() function is executed and user can 
+          add his own code by customization of function pointer HAL_SMARTCARD_ErrorCallback    
+
+    *** SMARTCARD HAL driver macros list ***
+    ============================================= 
+    [..]
+      Below the list of most used macros in SMARTCARD HAL driver.
+       
+      (+) __HAL_SMARTCARD_ENABLE: Enable the SMARTCARD peripheral

+    [..]
+    This subsection provides a set of functions allowing to initialize the USART 
+    in Smartcard mode.
+    [..]
+    The Smartcard interface is designed to support asynchronous protocol Smartcards as
+    defined in the ISO 7816-3 standard.
+    [..]
+    The USART can provide a clock to the smartcard through the SCLK output.
+    In smartcard mode, SCLK is not associated to the communication but is simply derived 
+    from the internal peripheral input clock through a 5-bit prescaler.
+    [..]
+      (+) 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 SmartCard frame formats are as listed in the following table:
+   +-------------------------------------------------------------+
+   |   M bit |  PCE bit  |            USART frame                |
+   |---------------------|---------------------------------------|
+   |    0    |    0      |    | SB | 8 bit data | STB |          |
+   |---------|-----------|---------------------------------------|

+    This subsection provides a set of functions allowing to manage the SMARTCARD data transfers.
+    [..]
+    IrDA is a half duplex communication protocol. If the Transmitter is busy, any data
+    on the IrDA receive line will be ignored by the IrDA decoder and if the Receiver 
+    is busy, data on the TX from the USART to IrDA will not be encoded by IrDA.
+    While receiving data, transmission should be avoided as the data to be transmitted
+    could be corrupted.
+
+    (#) 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()

+                        ##### 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.

+
+    (#) 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

+  ==============================================================================
+                          ##### How to use this driver #####
+  ==============================================================================  
+  [..]
+    This driver is a generic layered driver which contains a set of APIs used to 
+    control SRAM memories. It uses the FMC layer functions to interface 
+    with SRAM devices.  
+    The following sequence should be followed to configure the FMC/FSMC to interface
+    with SRAM/PSRAM memories: 
+      
+   (#) Declare a SRAM_HandleTypeDef handle structure, for example:
+          SRAM_HandleTypeDef  hsram; and: 
+          
+       (++) Fill the SRAM_HandleTypeDef handle "Init" field with the allowed 
+            values of the structure member.
+            
+       (++) Fill the SRAM_HandleTypeDef handle "Instance" field with a predefined 
+            base register instance for NOR or SRAM device 
+                         
+       (++) Fill the SRAM_HandleTypeDef handle "Extended" field with a predefined
+            base register instance for NOR or SRAM extended mode 
+             
+   (#) Declare two FMC_NORSRAM_TimingTypeDef structures, for both normal and extended 
+       mode timings; for example:
+          FMC_NORSRAM_TimingTypeDef  Timing and FMC_NORSRAM_TimingTypeDef  ExTiming;
+      and fill its fields with the allowed values of the structure member.
+      
+   (#) Initialize the SRAM Controller by calling the function HAL_SRAM_Init(). This function
+       performs the following sequence:
+          
+       (##) MSP hardware layer configuration using the function HAL_SRAM_MspInit()
+       (##) Control register configuration using the FMC NORSRAM interface function 
+            FMC_NORSRAM_Init()
+       (##) Timing register configuration using the FMC NORSRAM interface function 
+            FMC_NORSRAM_Timing_Init()
+       (##) Extended mode Timing register configuration using the FMC NORSRAM interface function 
+            FMC_NORSRAM_Extended_Timing_Init()
+       (##) Enable the SRAM device using the macro __FMC_NORSRAM_ENABLE()    
+
+   (#) At this stage you can perform read/write accesses from/to the memory connected 
+       to the NOR/SRAM Bank. You can perform either polling or DMA transfer using the
+       following APIs:
+       (++) HAL_SRAM_Read()/HAL_SRAM_Write() for polling read/write access
+       (++) HAL_SRAM_Read_DMA()/HAL_SRAM_Write_DMA() for DMA read/write transfer
+       
+   (#) You can also control the SRAM device by calling the control APIs HAL_SRAM_WriteOperation_Enable()/
+       HAL_SRAM_WriteOperation_Disable() to respectively enable/disable the SRAM write operation  
+       
+   (#) You can continuously monitor the SRAM device HAL state by calling the function
+       HAL_SRAM_GetState()              
+

+  ==============================================================================
+  [..] 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               
+   
+                        ##### How to use this driver #####
+  ==============================================================================
+    [..]
+     (#) Initialize the TIM low level resources by implementing the following functions 
+         depending from feature used :
+           (++) Time Base : HAL_TIM_Base_MspInit() 
+           (++) Input Capture : HAL_TIM_IC_MspInit()
+           (++) Output Compare : HAL_TIM_OC_MspInit()

+           (++) Encoder mode output : HAL_TIM_Encoder_MspInit()
+           
+     (#) Initialize the TIM low level resources :
+        (##) 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 depending from the feature used: 
+           (++) Time Base : HAL_TIM_Base_Start(), HAL_TIM_Base_Start_DMA(), HAL_TIM_Base_Start_IT()
+           (++) Input Capture :  HAL_TIM_IC_Start(), HAL_TIM_IC_Start_DMA(), HAL_TIM_IC_Start_IT()
+           (++) Output Compare : HAL_TIM_OC_Start(), HAL_TIM_OC_Start_DMA(), HAL_TIM_OC_Start_IT()
+           (++) PWM generation : HAL_TIM_PWM_Start(), HAL_TIM_PWM_Start_DMA(), HAL_TIM_PWM_Start_IT()
+           (++) One-pulse mode output : HAL_TIM_OnePulse_Start(), HAL_TIM_OnePulse_Start_IT()
+           (++) Encoder mode output : HAL_TIM_Encoder_Start(), HAL_TIM_Encoder_Start_DMA(), HAL_TIM_Encoder_Start_IT().
+

+         HAL_TIM_DMABurst_WriteStart()
+         HAL_TIM_DMABurst_ReadStart()

+  ==============================================================================
+                      ##### TIMER Extended features #####
+  ==============================================================================
+  [..] 
+    The Timer Extension features include: 
+    (#) Complementary outputs with programmable dead-time 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.
+    (#) Break input to put the timer output signals in reset state or in a known state.
+    (#) Supports incremental (quadrature) encoder and hall-sensor circuitry for 
+        positioning purposes                
+   
+                        ##### How to use this driver #####
+  ==============================================================================
+  [..]
+     (#) Initialize the TIM low level resources by implementing the following functions 
+         depending from feature used :
+           (++) Complementary Output Compare : HAL_TIM_OC_MspInit()
+           (++) Complementary PWM generation : HAL_TIM_PWM_MspInit()
+           (++) Complementary One-pulse mode output : HAL_TIM_OnePulse_MspInit()
+           (++) Hall Sensor output : HAL_TIM_HallSensor_MspInit()
+           
+     (#) Initialize the TIM low level resources :
+        (##) 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_TIMEx_HallSensor_Init and HAL_TIMEx_ConfigCommutationEvent: to use the 
+             Timer Hall Sensor Interface and the commutation event with the corresponding 
+             Interrupt and DMA request if needed (Note that One Timer is used to interface 
+             with the Hall sensor Interface and another Timer should be used to use 
+             the commutation event).
+
+    (#) Activate the TIM peripheral using one of the start functions: 
+           (++) Complementary Output Compare : HAL_TIMEx_OCN_Start(), HAL_TIMEx_OCN_Start_DMA(), HAL_TIMEx_OC_Start_IT()
+           (++) Complementary PWM generation : HAL_TIMEx_PWMN_Start(), HAL_TIMEx_PWMN_Start_DMA(), HAL_TIMEx_PWMN_Start_IT()
+           (++) Complementary One-pulse mode output : HAL_TIMEx_OnePulseN_Start(), HAL_TIMEx_OnePulseN_Start_IT()
+           (++) Hall Sensor output : HAL_TIMEx_HallSensor_Start(), HAL_TIMEx_HallSensor_Start_DMA(), HAL_TIMEx_HallSensor_Start_IT().

+  ==============================================================================
+                        ##### 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 implement 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 huart 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 API's(HAL_UART_Init() and HAL_HalfDuplex_Init()) configures also the 
+            low level Hardware GPIO, CLOCK, CORTEX...etc) by calling the customed 
+            HAL_UART_MspInit() API.
+          
+    (#) Three mode of operations are available within this driver :     
+

+    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:
+   +-------------------------------------------------------------+     
+   |   M bit |  PCE bit  |            UART frame                 |

+  ==============================================================================  
+  [..]
+    This subsection provides a set of functions allowing to manage the UART asynchronous
+    and Half duplex 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.  
+       (++) Non-Blocking mode: The communication is performed using Interrupts 
+            or DMA, these APIs 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()
+
+    (#) No-Blocking mode functions with DMA are:
+        (++) HAL_UART_Transmit_DMA()
+        (++) HAL_UART_Receive_DMA()
+
+    (#) A set of Transfer Complete Callbacks are provided in Non-Blocking mode:
+        (++) HAL_UART_TxCpltCallback()
+        (++) 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.
+        (##) 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.
+                    
+        -@@- The specific USART interrupts (Transmission complete interrupt, 
+             RXNE interrupt and Error Interrupts) will be managed using the macros
+             __USART_ENABLE_IT() and __USART_DISABLE_IT() inside the transmit and receive process.
+          
+    (#) Three mode of operations are available within this driver :     
+

+  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:
+   +-------------------------------------------------------------+
+   |   M bit |  PCE bit  |            USART frame                |

+
+    (#) There are two mode of transfer:
+        (++) Blocking mode: The communication is performed in polling mode.

+        (++) 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.

+  * @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

+  ==============================================================================
+                      ##### 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 clock (Hz) = PCLK1 / (4096 * Prescaler)
+    (+) WWDG timeout (mS) = 1000 * Counter / WWDG clock
+    (+) WWDG Counter refresh is allowed between the following limits :
+        (++) min time (mS) = 1000 * (Counter – Window) / WWDG clock
+        (++) max time (mS) = 1000 * (Counter – 0x40) / WWDG clock
+    
+    (+) Min-max timeout value at 50 MHz(PCLK1): 81.9 us / 41.9 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(). At EWI HAL_WWDG_WakeupCallback is executed and user can 
+        add his own code by customization of function pointer HAL_WWDG_WakeupCallback
+        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_IWDG_GET_FLAG: Get the selected WWDG's flag status
+      (+) __HAL_IWDG_CLEAR_FLAG: Clear the WWDG's pending flags 
+      (+) __HAL_IWDG_RELOAD_COUNTER: Enables the WWDG early wakeup interrupt

+  *           + Initialization/de-initialization functions

+  ==============================================================================
+                        ##### FMC peripheral features #####
+  ==============================================================================
+  [..] The Flexible memory controller (FMC) includes three memory controllers:
+       (+) The NOR/PSRAM memory controller
+       (+) The NAND/PC Card memory controller
+       (+) The Synchronous DRAM (SDRAM) controller 
+       
+  [..] The FMC functional block makes the interface with synchronous and asynchronous static
+       memories, SDRAM memories, and 16-bit PC memory cards. Its main purposes are:
+       (+) to translate AHB transactions into the appropriate external device protocol
+       (+) to meet the access time requirements of the external memory devices
+   
+  [..] All external memories share the addresses, data and control signals with the controller.
+       Each external device is accessed by means of a unique Chip Select. The FMC performs
+       only one access at a time to an external device.
+       The main features of the FMC controller are the following:
+        (+) Interface with static-memory mapped devices including:
+           (++) Static random access memory (SRAM)
+           (++) Read-only memory (ROM)
+           (++) NOR Flash memory/OneNAND Flash memory
+           (++) PSRAM (4 memory banks)
+           (++) 16-bit PC Card compatible devices
+           (++) Two banks of NAND Flash memory with ECC hardware to check up to 8 Kbytes of
+                data
+        (+) Interface with synchronous DRAM (SDRAM) memories
+        (+) Independent Chip Select control for each memory bank
+        (+) Independent configuration for each memory bank
+

+  ==============================================================================                  
+    [..] The Flexible static memory controller (FSMC) includes two memory controllers:
+         (+) The NOR/PSRAM memory controller
+         (+) The NAND/PC Card memory controller
+       
+    [..] The FSMC functional block makes the interface with synchronous and asynchronous static
+         memories, SDRAM memories, and 16-bit PC memory cards. Its main purposes are:
+         (+) to translate AHB transactions into the appropriate external device protocol.
+         (+) to meet the access time requirements of the external memory devices.
+   
+    [..] All external memories share the addresses, data and control signals with the controller.
+         Each external device is accessed by means of a unique Chip Select. The FSMC performs
+         only one access at a time to an external device.
+         The main features of the FSMC controller are the following:
+          (+) Interface with static-memory mapped devices including:
+             (++) Static random access memory (SRAM).
+             (++) Read-only memory (ROM).
+             (++) NOR Flash memory/OneNAND Flash memory.
+             (++) PSRAM (4 memory banks).
+             (++) 16-bit PC Card compatible devices.
+             (++) Two banks of NAND Flash memory with ECC hardware to check up to 8 Kbytes of
+                  data.
+          (+) Independent Chip Select control for each memory bank.
+          (+) Independent configuration for each memory bank.          
+

+  ==============================================================================
+                       ##### SDMMC peripheral features #####
+  ==============================================================================        
+    [..] The SD/SDIO MMC card host interface (SDIO) provides an interface between the APB2
+         peripheral bus and MultiMedia cards (MMCs), SD memory cards, SDIO cards and CE-ATA
+         devices.
+
+    [..] The MultiMedia Card system specifications are available through the MultiMedia Card
+         Association website at www.mmca.org, published by the MMCA technical committee.
+         SD memory card and SD I/O card system specifications are available through the SD card
+         Association website at www.sdcard.org.
+         CE-ATA system specifications are available through the CE-ATA work group web site at
+         www.ce-ata.org.
+    
+    [..] The SDIO features include the following:
+         (+) Full compliance with MultiMedia Card System Specification Version 4.2. Card support
+             for three different databus modes: 1-bit (default), 4-bit and 8-bit
+         (+) Full compatibility with previous versions of MultiMedia Cards (forward compatibility)
+         (+) Full compliance with SD Memory Card Specifications Version 2.0
+         (+) Full compliance with SD I/O Card Specification Version 2.0: card support for two
+             different data bus modes: 1-bit (default) and 4-bit
+         (+) Full support of the CE-ATA features (full compliance with CE-ATA digital protocol
+             Rev1.1)
+         (+) Data transfer up to 48 MHz for the 8 bit mode
+         (+) Data and command output enable signals to control external bidirectional drivers.
+                 
+   
+                           ##### How to use this driver #####
+  ==============================================================================
+    [..]
+      This driver is a considered as a driver of service for external devices drivers 
+      that interfaces with the SDIO peripheral.
+      According to the device used (SD card/ MMC card / SDIO card ...), a set of APIs 
+      is used in the device's driver to perform SDIO operations and functionalities.
+   
+      This driver is almost transparent for the final user, it is only used to implement other
+      functionalities of the external device.
+   
+    [..]
+      (+) The SDIO clock (SDIOCLK = 48 MHz) is coming from a specific output of PLL 
+          (PLL48CLK). Before start working with SDIO peripheral make sure that the
+          PLL is well configured.
+          The SDIO peripheral uses two clock signals:
+          (++) SDIO adapter clock (SDIOCLK = 48 MHz)
+          (++) APB2 bus clock (PCLK2)
+       
+          -@@- PCLK2 and SDIO_CK clock frequencies must respect the following condition:
+               Frequency(PCLK2) >= (3 / 8 x Frequency(SDIO_CK))
+  
+      (+) Enable/Disable peripheral clock using RCC peripheral macros related to SDIO
+          peripheral.
+
+      (+) Enable the Power ON State using the HAL_SDIO_PowerState_ON(hsdio) 
+          function and disable it using the function HAL_SDIO_PowerState_OFF(hsdio).
+                
+      (+) Enable/Disable the clock using the __SDIO_ENABLE()/__SDIO_DISABLE() macros.
+  
+      (+) Enable/Disable the peripheral interrupts using the macros __SDIO_ENABLE_IT(hsdio, IT) 
+          and __SDIO_DISABLE_IT(hsdio, IT) if you need to use interrupt mode. 
+  
+      (+) When using the DMA mode 
+          (++) Configure the DMA in the MSP layer of the external device
+          (++) Active the needed channel Request 
+          (++) Enable the DMA using __SDIO_DMA_ENABLE() macro or Disable it using the macro
+               __SDIO_DMA_DISABLE().
+  
+      (+) To control the CPSM (Command Path State Machine) and send 
+          commands to the card use the HAL_SDIO_SendCommand(), 
+          HAL_SDIO_GetCommandResponse() and HAL_SDIO_GetResponse() functions. First, user has
+          to fill the command structure (pointer to SDIO_CmdInitTypeDef) according 
+          to the selected command to be sent.
+          The parameters that should be filled are:
+           (++) Command Argument
+           (++) Command Index
+           (++) Command Response type
+           (++) Command Wait
+           (++) CPSM Status (Enable or Disable).
+  
+          -@@- To check if the command is well received, read the SDIO_CMDRESP
+              register using the HAL_SDIO_GetCommandResponse().
+              The SDIO responses registers (SDIO_RESP1 to SDIO_RESP2), use the
+              HAL_SDIO_GetResponse() function.
+  
+      (+) To control the DPSM (Data Path State Machine) and send/receive 
+           data to/from the card use the HAL_SDIO_DataConfig(), HAL_SDIO_GetDataCounter(), 
+          HAL_SDIO_ReadFIFO(), HAL_SDIO_WriteFIFO() and HAL_SDIO_GetFIFOCount() functions.
+

+  *
+  *   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_stm32f4xx.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.

+  *           constant and the selected clock source:

+  *           - If SYSCLK source is HSI, SystemCoreClock will contain the HSI_VALUE(*)

+  *           - If SYSCLK source is PLL, SystemCoreClock will contain the HSE_VALUE(**) 
+  *             or HSI_VALUE(*) multiplied/divided by the PLL factors.
+  *         
+  *         (*) HSI_VALUE is a constant defined in stm32f4xx_hal_conf.h file (default value
+  *             16 MHz) but the real value may vary depending on the variations
+  *             in voltage and temperature.

+  *              is same as the real frequency of the crystal used. Otherwise, this function

+  *
