		uint8_t	channel[]
	)

ADC Set a Regular Channel Conversion Sequence.

Define a sequence of channels to be converted as a regular group with a length from 1 to 16 channels. If this is called during conversion, the current conversion is reset and conversion begins again with the newly defined group.

Parameters

[in]	adc	ADC block register address base ADC register base addresses
[in]	length	Number of channels in the group, range 0..16
[in]	channel	Set of channels in sequence, range ADC Channel Numbers

◆ adc_set_resolution()

void adc_set_resolution	(	uint32_t	adc,
		uint16_t	resolution
	)

ADC Set Resolution.

ADC Resolution can be reduced from 12 bits to 10, 8 or 6 bits for a corresponding reduction in conversion time.

Parameters

[in]	adc	Unsigned int32. ADC base address (ADC register base addresses)
[in]	resolution	Unsigned int16. Resolution value (adc_api_res)

◆ adc_set_right_aligned()

void adc_set_right_aligned ( uint32_t adc )

ADC Set the Data as Right Aligned.

Parameters

[in] adc Unsigned int32. ADC base address (ADC register base addresses)

◆ adc_set_sample_time()

void adc_set_sample_time	(	uint32_t	adc,
		uint8_t	channel,
		uint8_t	time
	)

ADC Set the Sample Time for a Single Channel.

The sampling time can be selected in ADC clock cycles, exact values depend on the device.

Parameters

[in]	adc	ADC block register address base ADC register base addresses
[in]	channel	ADC Channel integer ADC Channel Numbers
[in]	time	Sampling time selection from ADC Sample Time Selection values

◆ adc_set_sample_time_on_all_channels()

void adc_set_sample_time_on_all_channels	(	uint32_t	adc,
		uint8_t	time
	)

ADC Set the Sample Time for All Channels.

The sampling time can be selected in ADC clock cycles, exact values depend on the device.

Parameters

[in]	adc	ADC block register address base ADC register base addresses
[in]	time	Sampling time selection from ADC Sample Time Selection values

◆ adc_set_single_conversion_mode()

void adc_set_single_conversion_mode ( uint32_t adc )

Enable Single Conversion Mode In this mode the ADC performs a conversion of one channel or a channel group and stops.

Parameters

[in] adc ADC block register address base ADC register base addresses

Definition at line 201 of file adc_common_v2.c.

References ADC_CFGR1.

◆ adc_start_conversion_regular()

void adc_start_conversion_regular ( uint32_t adc )

ADC Software Triggered Conversion on Regular Channels.

This starts conversion on a set of defined regular channels. Depending on the configuration bits EXTEN, a conversion will start immediately (software trigger configuration) or once a regular hardware trigger event occurs (hardware trigger configuration)

Parameters

[in] adc ADC block register address base ADC register base addresses
