- ==============================================================================
- ##### ADC specific features #####
- ==============================================================================
- [..]
- (#) 12-bit, 10-bit, 8-bit or 6-bit configurable resolution
-
- (#) Interrupt generation at the end of regular conversion, end of injected
- conversion, and in case of analog watchdog or overrun events.
-
- (#) Single and continuous conversion modes.
-
- (#) Scan mode for automatic conversion of channel 0 to channel 'n'.
-
- (#) Data alignment with in-built data coherency.
-
- (#) Channel-wise programmable sampling time.
-
- (#) ADC conversion Regular or Injected groups.
-
- (#) External trigger (timer or EXTI) with configurable polarity for both
- regular and injected groups.
-
- (#) DMA request generation for transfer of conversions data of regular group.
-
- (#) ADC calibration
-
- (#) ADC offset on injected channels
-
- (#) ADC supply requirements: 2.4 V to 3.6 V at full speed and down to 1.8 V at
- slower speed.
-
- (#) ADC input range: from Vref (connected to Vssa) to Vref+ (connected to
- Vdda or to an external voltage reference).
-
-
- ##### How to use this driver #####
- ==============================================================================
- [..]
-
- (#) Enable the ADC interface
- As prerequisite, ADC clock must be configured at RCC top level.
- Two clocks settings are mandatory:
- - ADC clock (core clock):
- Example:
- Into HAL_ADC_MspInit() (recommended code location):
- __ADC1_CLK_ENABLE();
-
- - ADC clock (conversions clock):
- Only one possible clock source: derived from HSI RC 16MHz oscillator
- (HSI).
- Example:
- Into HAL_ADC_MspInit() or with main setting of RCC:
- RCC_OscInitTypeDef RCC_OscInitStructure;
- HAL_RCC_GetOscConfig(&RCC_OscInitStructure);
- RCC_OscInitStructure.OscillatorType = (... | RCC_OSCILLATORTYPE_HSI);
- RCC_OscInitStructure.HSIState = RCC_HSI_ON;
- RCC_OscInitStructure.HSICalibrationValue = RCC_HSICALIBRATION_DEFAULT;
- RCC_OscInitStructure.PLL.PLLState = RCC_PLL_NONE;
- RCC_OscInitStructure.PLL.PLLSource = ...
- RCC_OscInitStructure.PLL...
- HAL_RCC_OscConfig(&RCC_OscInitStructure);
-
- Note: ADC is connected directly to HSI RC 16MHz oscillator.
- Therefore, RCC PLL setting has no impact on ADC.
- PLL can be disabled (".PLL.PLLState = RCC_PLL_NONE") or
- enabled with HSI16 as clock source
- (".PLL.PLLSource = RCC_PLLSOURCE_HSI") to be used as device
- main clock source SYSCLK.
- The only mandatory setting is ".HSIState = RCC_HSI_ON"
-
- Note: ADC clock prescaler is configured at ADC level with
- parameter "ClockPrescaler" using function HAL_ADC_Init().
-
- (#) ADC pins configuration
- (++) Enable the clock for the ADC GPIOs using the following function:
- __GPIOx_CLK_ENABLE();
- (++) Configure these ADC pins in analog mode using HAL_GPIO_Init();
-
- (#) Configure the ADC parameters (conversion resolution, data alignment,
- continuous mode, ...) using the HAL_ADC_Init() function.
-
- (#) Activate the ADC peripheral using one of the start functions:
- HAL_ADC_Start(), HAL_ADC_Start_IT(), HAL_ADC_Start_DMA().
-
- *** Channels configuration to regular group ***
- ================================================
- [..]
- (+) To configure the ADC regular group features, use
- HAL_ADC_Init() and HAL_ADC_ConfigChannel() functions.
- (+) To read the ADC converted values, use the HAL_ADC_GetValue() function.
-
- *** DMA for regular group configuration ***
- ===========================================
- [..]
- (+) To enable the DMA mode for regular group, use the
- HAL_ADC_Start_DMA() function.
- (+) To enable the generation of DMA requests continuously at the end of
- the last DMA transfer, use the HAL_ADC_Init() function.
