uint32_t ADC_InjectionConfTypeDef::InjectedChannel
Selection of ADC channel to configure This parameter can be a value of
ADC_channels
package pins. Refer to device datasheet for channels availability.
uint32_t ADC_InjectionConfTypeDef::InjectedRank
Rank in the injected group sequencer This parameter must be a value of
ADCEx_injected_rank
conversion sequencer, rank containing a previous channel setting can be overwritten
by the new channel setting (or parameter number of conversions can be adjusted)
uint32_t ADC_InjectionConfTypeDef::InjectedSamplingTime
Sampling time value to be set for the selected channel. Unit: ADC clock cycles
Conversion time is the addition of sampling time and processing time (12 ADC clock
cycles at ADC resolution 12 bits, 11 cycles at 10 bits, 9 cycles at 8 bits, 7 cycles at 6
bits). This parameter can be a value of
parameter updates the parameter property of the channel, that can be used into
regular and/or injected groups. If this same channel has been previously configured in
the other group (regular/injected), it will be updated to last setting. Note: In case of
usage of internal measurement channels (VrefInt/Vbat/TempSensor), sampling time
constraints must be respected (sampling time can be adjusted in function of ADC
clock frequency and sampling time setting) Refer to device datasheet for timings
values, parameters TS_vrefint, TS_temp (values rough order: 4us min).
uint32_t ADC_InjectionConfTypeDef::InjectedOffset
Defines the offset to be subtracted from the raw converted data (for channels set on
injected group only). Offset value must be a positive number. Depending of ADC
resolution selected (12, 10, 8 or 6 bits), this parameter must be a number between
Min_Data = 0x000 and Max_Data = 0xFFF, 0x3FF, 0xFF or 0x3F respectively.
uint32_t ADC_InjectionConfTypeDef::InjectedNbrOfConversion
Specifies the number of ranks that will be converted within the injected group
sequencer. To use the injected group sequencer and convert several ranks,
parameter 'ScanConvMode' must be enabled. This parameter must be a number
between Min_Data = 1 and Max_Data = 4. Caution: this setting impacts the entire
injected group. Therefore, call of HAL_ADCEx_InjectedConfigChannel() to configure
