HAL_ADC_Start_IT() ) with parameter EOCSelection set to end of each conversion
or in mode 'transfer by DMA' (function HAL_ADC_Start_DMA()). If overrun feature is
intended to be bypassed, use ADC in mode 'polling' or 'interruption' with parameter
EOCSelection must be set to end of sequence
uint32_t ADC_InitTypeDef::ContinuousConvMode
Specifies whether the conversion is performed in single mode (one conversion) or
continuous mode for regular group, after the selected trigger occurred (software start
or external trigger). This parameter can be set to ENABLE or DISABLE.
uint32_t ADC_InitTypeDef::NbrOfConversion
Specifies the number of ranks that will be converted within the regular group
sequencer. To use regular group sequencer and convert several ranks, parameter
'ScanConvMode' must be enabled. This parameter must be a number between
Min_Data = 1 and Max_Data = 16.
uint32_t ADC_InitTypeDef::DiscontinuousConvMode
Specifies whether the conversions sequence of regular group is performed in
Complete-sequence/Discontinuous-sequence (main sequence subdivided in
successive parts). Discontinuous mode is used only if sequencer is enabled
(parameter 'ScanConvMode'). If sequencer is disabled, this parameter is discarded.
Discontinuous mode can be enabled only if continuous mode is disabled. If continuous
mode is enabled, this parameter setting is discarded. This parameter can be set to
ENABLE or DISABLE.
uint32_t ADC_InitTypeDef::NbrOfDiscConversion
Specifies the number of discontinuous conversions in which the main sequence of
regular group (parameter NbrOfConversion) will be subdivided. If parameter
'DiscontinuousConvMode' is disabled, this parameter is discarded. This parameter
must be a number between Min_Data = 1 and Max_Data = 8.
uint32_t ADC_InitTypeDef::ExternalTrigConv
Selects the external event used to trigger the conversion start of regular group. If set
to ADC_SOFTWARE_START, external triggers are disabled. If set to external trigger
source, triggering is on event rising edge by default. This parameter can be a value of
ADC_External_trigger_Source_Regular
uint32_t ADC_InitTypeDef::ExternalTrigConvEdge
Selects the external trigger edge of regular group. If trigger is set to
ADC_SOFTWARE_START, this parameter is discarded. This parameter can be a
value of ADC_External_trigger_edge_Regular
uint32_t ADC_InitTypeDef::DMAContinuousRequests
Specifies whether the DMA requests are performed in one shot mode (DMA transfer
stop when number of conversions is reached) or in Continuous mode (DMA transfer
unlimited, whatever number of conversions). Note: In continuous mode, DMA must be
configured in circular mode. Otherwise an overrun will be triggered when DMA buffer
maximum pointer is reached. Note: This parameter must be modified when no
conversion is on going on both regular and injected groups (ADC disabled, or ADC
enabled without continuous mode or external trigger that could launch a conversion).
This parameter can be set to ENABLE or DISABLE.
