1.8.2.12 ADC_ConversionSequenceSet Function

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.
