Function Documentation

adc_off()

void adc_off

(

const adc_peripheral_t

adc

)

Stops the ADC conversion.

The ADC will be powered off upon calling this command and instantly stop the conversion procedure.

Parameters

adc	The selected ADC

Returns

None

adc_on()

void adc_on

(

const adc_peripheral_t

adc

)

Starts the ADC conversion.

The ADC will be powered on upon calling this command and start the conversion procedure as configured. Dummy reads are included.

Parameters

adc	The selected ADC

Returns

None

adc_read()

uint16_t adc_read

(

const adc_peripheral_t

adc

)

Reads the last ADC conversion result.

Parameters

adc	The selected ADC

Returns

The conversion result

adc_set_modes()

void adc_set_modes	(	const adc_peripheral_t	adc,
		const struct ADCModes	config )

Sets the ADC modes according to the configuration.

The configuration values are specified within the adc_config struct. Some modes may not work as expected yet.

Parameters

adc	The selected ADC
config	The ADC configuration

Returns

None

adc_set_prescaler()

void adc_set_prescaler

(

const adc_prescaler_t

value

)

Sets the ADC Prescaler divider to the specified value.

The available dividers for the ADC Prescaler are specified in the adc_prescaler_t enum. Any other value will be ignored.

Parameters

value

The prescaler divider value

Returns

None

adc_set_resolution()

void adc_set_resolution	(	const adc_peripheral_t	adc,
		const adc_res_t	value )

Sets the ADC resolution to the specified value.

The available resolutions for the ADC channel reads are specified in the adc_res_t enum. Any other value will be ignored.

Parameters

adc	The selected ADC
value	The resolution of the ADC conversions

Returns

None

adc_set_samplerate()

void adc_set_samplerate	(	const adc_peripheral_t	adc,
		const uint8_t	channel,
		const adc_samplerate_t	value )

Sets the ADC sampling rate to the specified value.

The available sampling rates for the ADC channel reads are specified in the adc_res_t enum (in clock cycles). Any other value will be ignored.

Parameters

adc	The selected ADC
channel	The selected channel (0..19)
value	The clock cycles of the ADC conversions

Returns

None

adc_set_seq()

void adc_set_seq	(	const adc_peripheral_t	adc,
		const uint8_t *	seq,
		const uint8_t	count )

Sets the ADC conversion sequence to the specified order.

The sequence consists of 16 5-bit elements. Bits 6..8 will be ignored.

Parameters

adc	The selected ADC
seq	Pointer to channel conversion sequence array
count	The total amount of conversions

Returns

None
