3.2.12 Regular Channels Configuration functions
3.2.12.1 ADC_RegularChannelConfig
Function Name
void ADC_RegularChannelConfig ( ADC_TypeDef * ADCx,
uint8_t ADC_Channel, uint8_t Rank, uint8_t
ADC_SampleTime)
Function Description
Configures for the selected ADC regular channel its
corresponding rank in the sequencer and its sample time.
Parameters
 ADCx : where x can be 1, 2, 3 or 4 to select the ADC
peripheral.
 ADC_Channel : the ADC channel to configure. This
parameter can be one of the following values:
 ADC_Channel_1 : ADC Channel1 selected
 ADC_Channel_2 : ADC Channel2 selected
 ADC_Channel_3 : ADC Channel3 selected
 ADC_Channel_4 : ADC Channel4 selected
 ADC_Channel_5 : ADC Channel5 selected
 ADC_Channel_6 : ADC Channel6 selected
 ADC_Channel_7 : ADC Channel7 selected
 ADC_Channel_8 : ADC Channel8 selected
 ADC_Channel_9 : ADC Channel9 selected
 ADC_Channel_10 : ADC Channel10 selected
 ADC_Channel_11 : ADC Channel11 selected
 ADC_Channel_12 : ADC Channel12 selected
 ADC_Channel_13 : ADC Channel13 selected
 ADC_Channel_14 : ADC Channel14 selected
 ADC_Channel_15 : ADC Channel15 selected
 ADC_Channel_16 : ADC Channel16 selected
 ADC_Channel_17 : ADC Channel17 selected
 ADC_Channel_18 : ADC Channel18 selected
 Rank : The rank in the regular group sequencer. This
parameter must be between 1 to 16.
 ADC_SampleTime : The sample time value to be set for the
selected channel. This parameter can be one of the following
values:
 ADC_SampleTime_1Cycles5 : Sample time equal to
1.5 cycles
 ADC_SampleTime_2Cycles5 : Sample time equal to
2.5 cycles
 ADC_SampleTime_4Cycles5 : Sample time equal to
4.5 cycles
 ADC_SampleTime_7Cycles5 : Sample time equal to
7.5 cycles
 ADC_SampleTime_19Cycles5 : Sample time equal to
19.5 cycles
 ADC_SampleTime_61Cycles5 : Sample time equal to
61.5 cycles
