Function Documentation

adc_get()

int16_t adc_get	(	uint8_t	channel,
		uint8_t	ref,
		uint8_t	div )

Performs a single conversion on a given ADC channel.

Parameters

channel	The channel used for the conversion: SOC_ADC_ADCCON_CH_x
ref	The reference voltage used for the conversion: SOC_ADC_ADCCON_REF_x
div	The decimation rate used for the conversion: SOC_ADC_ADCCON_DIV_x

Returns

Signed 16-bit conversion result: 2's complement, ENOBs in MSBs

Note

PD[5:4] are not usable when the temperature sensor is selected.
