Detailed Description

ADC Basic configuration API.

Function Documentation

adc_calibrate_start()

void adc_calibrate_start

(

uint32_t

adc

)

ADC Start the calibration procedure.

Deprecated:

Replaced by adc_calibrate/_async/is_calibrating

Parameters

[in]

adc

Unsigned int32. ADC base address (ADC register base addresses)

Definition at line 410 of file adc.c.

References ADC_CR, and ADC_CR_ADCAL.

adc_calibrate_wait_finish()

void adc_calibrate_wait_finish

(

uint32_t

adc

)

ADC Wait to finish the ADC calibration procedure.

Deprecated:

Replaced by adc_calibrate/_async/is_calibrating

Parameters

[in]

adc

Unsigned int32. ADC base address (ADC register base addresses)

Definition at line 422 of file adc.c.

References ADC_CR, and ADC_CR_ADCAL.

adc_disable_vbat_sensor()

void adc_disable_vbat_sensor

(

void

)

ADC Disable The VBat Sensor.

Disabling this will reduce power consumption from the battery voltage measurement.

Definition at line 398 of file adc.c.

References ADC1, and ADC_CCR.

adc_enable_vbat_sensor()

void adc_enable_vbat_sensor

(

void

)

ADC Enable The VBat Sensor.

This enables the battery voltage measurements on channel 17.

adc_set_clk_source()

void adc_set_clk_source	(	uint32_t	adc,
		uint32_t	source
	)

ADC Set Clock Source.

The ADC clock taken from the many sources.

Parameters

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

Definition at line 309 of file adc.c.

References ADC_CFGR2.

adc_set_regular_sequence()

void adc_set_regular_sequence	(	uint32_t	adc,
		uint8_t	length,
		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 18 channels. If this is called during conversion, the current conversion is reset and conversion begins again with the newly defined group.

Warning

This core doesn't support the random order of ADC conversions. The channel list must be ordered by channel number.

Parameters

[in]	adc	Unsigned int32. ADC base address (ADC register base addresses)
[in]	length	Unsigned int8. Number of channels in the group.
[in]	channel	Unsigned int8[]. Set of channels to convert, integers 0..18.

Definition at line 331 of file adc.c.

References ADC_CFGR1, ADC_CFGR1_SCANDIR, ADC_CHSELR, and cm3_assert_not_reached.

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 from 1.5 to 239.5, same for all channels.

Parameters

[in]	adc	Unsigned int32. ADC base address (ADC register base addresses)
[in]	time	Unsigned int8. Sampling time selection (ADC sampling time)
