C
void ADC_ConversionSequenceSet (ADC_CHANNEL *channelList, uint8_t numChannel) void ADC_ConversionSequenceSet (ADC_CHANNEL_NUM *channelList, uint8_t numChannel)
Summary
Sets the user sequence of the channel conversion
Description
This function sets the order in which channels are converted.
Precondition
ADC_Initialize() must have been called first for the associate instance. Conversion should not be ongoing while changing the sequence.
Parameters
Param | Description |
---|---|
*channelList | pointer to the list of the channels which describes the order of conversion |
numChannel | Number of enabled channels in the list |
Returns
None.
Example
ADC_CHANNEL seq_order[4] = {ADC_CH3, ADC_CH5, ADC_CH1, ADC_CH2}; ADC_Initialize(); ADC_ConversionSequenceSet(seq_order, 0x4); ADC_ChannelsEnable(ADC_CH0_MASK | ADC_CH1_MASK | ADC_CH2_MASK | ADC_CH3_MASK);
ADC_CHANNEL_NUM seq_order[4] = {ADC_CH3, ADC_CH5, ADC_CH1, ADC_CH2}; ADC_Initialize(); ADC_ConversionSequenceSet(seq_order, 0x4); ADC_ChannelsEnable(ADC_CH0_MASK | ADC_CH1_MASK | ADC_CH2_MASK | ADC_CH3_MASK);
Remarks
Conversion order is set in this function and remains valid until user configures new conversion sequence order or reinitializes the peripheral. Array pointed to by *channelList must be valid during the call to this function. This function copies the array data into ADC HW registers.
