regular and injected groups.
(#) DMA request generation for transfer of conversions data of regular group.

(#) 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, 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.
