uint32_t ADC_InitTypeDef::ClockPrescaler
Select ADC clock prescaler. The clock is common for all the ADCs. This parameter
can be a value of ADC_ClockPrescaler
uint32_t ADC_InitTypeDef::Resolution
Configures the ADC resolution. This parameter can be a value of ADC_Resolution
uint32_t ADC_InitTypeDef::DataAlign
Specifies ADC data alignment to right (MSB on register bit 11 and LSB on register bit
0) (default setting) or to left (if regular group: MSB on register bit 15 and LSB on
register bit 4, if injected group (MSB kept as signed value due to potential negative
value after offset application): MSB on register bit 14 and LSB on register bit 3). This
parameter can be a value of ADC_Data_align
uint32_t ADC_InitTypeDef::ScanConvMode
Configures the sequencer of regular and injected groups. This parameter can be
associated to parameter 'DiscontinuousConvMode' to have main sequence subdivided
in successive parts. If disabled: Conversion is performed in single mode (one channel
converted, the one defined in rank 1). Parameters 'NbrOfConversion' and
'InjectedNbrOfConversion' are discarded (equivalent to set to 1). If enabled:
Conversions are performed in sequence mode (multiple ranks defined by
'NbrOfConversion'/'InjectedNbrOfConversion' and each channel rank). Scan direction
is upward: from rank1 to rank 'n'. This parameter can be set to ENABLE or DISABLE
uint32_t ADC_InitTypeDef::EOCSelection
Specifies what EOC (End Of Conversion) flag is used for conversion by polling and
interruption: end of conversion of each rank or complete sequence. This parameter
can be a value of ADC_EOCSelection. Note: For injected group, end of conversion
(flag&IT) is raised only at the end of the sequence. Therefore, if end of conversion is
set to end of each conversion, injected group should not be used with interruption
(HAL_ADCEx_InjectedStart_IT) or polling (HAL_ADCEx_InjectedStart and
HAL_ADCEx_InjectedPollForConversion). By the way, polling is still possible since
driver will use an estimated timing for end of injected conversion. Note: If overrun
feature is intended to be used, use ADC in mode 'interruption' (function
