+ slower speed.
+
+ (#) ADC input range: from Vref (connected to Vssa) to Vref+ (connected to

+
+
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+
+ (#) Enable the ADC interface
+ As prerequisite, into HAL_ADC_MspInit(), ADC clock must be configured
+ at RCC top level: clock source and clock prescaler.
+
+ For STM32F30x/STM32F33x devices:
+ Two possible clock sources: synchronous clock derived from AHB clock
+ or asynchronous clock derived from ADC dedicated PLL 72MHz.
+
+ For example, in case of device with a single ADC:
+ __ADC1_CLK_ENABLE() (mandatory)
+ __HAL_RCC_ADC1_CONFIG(RCC_ADC1PLLCLK_DIV1); (optional)
+
+ For example, in case of device with several ADCs:
+ if((hadc->Instance == ADC1) || (hadc->Instance == ADC2))
+ {
+ __ADC12_CLK_ENABLE() (mandatory)
+ __HAL_RCC_ADC12_CONFIG(RCC_ADC12PLLCLK_DIV1); (optional)
+ }
+ else
+ {
+ __ADC34_CLK_ENABLE() (mandatory)
+ __HAL_RCC_ADC34_CONFIG(RCC_ADC34PLLCLK_DIV1); (optional)
+ }
+
+ For STM32F37x devices:
+ Only one clock source: APB2 clock.
+ Example:
+ __HAL_RCC_ADC1_CONFIG(RCC_ADC1PCLK2_DIV2);
+
+ (#) 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()
+ HAL_ADCEx_InjectedStart(), HAL_ADCEx_InjectedStart_IT() or
+ HAL_ADC_MultiModeStart_DMA().
+
+ *** Channels to regular group configuration ***
+ ============================================
+ [..]
+ (+) To configure the ADC regular group features, use
+ HAL_ADC_Init() and HAL_ADC_ConfigChannel() functions.
+ (+) To activate the continuous mode, use the HAL_ADC_Init() function.
+ (+) To read the ADC converted values, use the HAL_ADC_GetValue() function.
+
+ *** Multimode ADCs configuration ***
+ ======================================================
+ [..]
+ (+) Multimode feature is available on devices with 2 ADCs or more.
+ (+) Refer to "Channels to regular group" description to
+ configure the ADC1 and ADC2 regular groups.
+ (+) Select the Multi mode ADC features (dual mode
+ simultaneous, interleaved, ...) and configure the DMA mode using
+ HAL_ADCEx_MultiModeConfigChannel() functions.
+ (+) Read the ADCs converted values using the HAL_ADCEx_MultiModeGetValue()
+ function.
+
+ *** DMA for regular 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.
+
+ *** Channels to injected group configuration ***
+ =============================================
+ [..]
+ (+) To configure the ADC Injected channels group features, use
+ HAL_ADCEx_InjectedConfigChannel() functions.
+ (+) To activate the continuous mode, use the HAL_ADC_Init() function.
+ (+) To read the ADC converted values, use the HAL_ADCEx_InjectedGetValue()
+ function.
