Detailed Description

Analog-to-Digital Converter (ADC) interface for reading analog signals.

Enumeration Type Documentation

Reference voltages.

Enumerator
ADC_REF_VIO	Use VIO_REF as reference voltage.
ADC_REF_2V5	Use 2.5V as reference voltage.
ADC_REF_1V25	Use 1.25V as reference voltage.

MYRIOTA_HARDWARE_API int ADCGetVoltage	(	uint8_t	PinNum,
		ADCReference	Reference,
		uint32_t *	mV
	)

Get the converted voltage (mV) from the MCU ADC port.

Parameters

PinNum	The ADC pin number. Can be PIN_ADC0 or PIN_ADC1.
Reference	The reference voltage.
mV[out]	Pointer to store the converted voltage in millivolts.

MYRIOTA_HARDWARE_API int ADCGetValue	(	uint8_t	PinNum,
		ADCReference	Reference,
		uint16_t *	Value
	)

Get raw value from the ADC port (0 - 0xFFF).

Parameters

PinNum	The ADC pin number. Can be PIN_ADC0 or PIN_ADC1.
Reference	The reference voltage.
Value[out]	Pointer to store the raw ADC value.
