Detailed Description

Pico ADC Class.

The purpose of this class is to manipulate the ADC on the board.

Constructor & Destructor Documentation

Adc() [1/2]

Adc

(

)

Constructor.

As default, the reference voltage is set to kAdcDefaultVRef value.

Adc() [2/2]

Adc ( float  vref )

explicit

Constructor.

Parameters

vref	Reference voltage of the ADC, in Volts.

Member Function Documentation

capture() [1/3]

float capture

(

uint

channel

)

Captures one sample from the ADC.

Captures and returns one sample. The valid channels are 0 to 3.

Parameters

channel

Number of the ADC channel (0 to 3).

Returns

Value of the sample, in Volts.

capture() [2/3]

float capture	(	uint	channel,
		size_t	size
	)

Captures multiple samples from the ADC.

Uses FIFO to capture samples from ADC. The valid channels are 0 to 3.

Parameters

channel	Number of the ADC channel (0 to 3).
size	Number of samples to capture.

Returns

Mean of all sample values, in Volts.

capture() [3/3]

float capture	(	uint	channel,
		float *	buf,
		size_t	size
	)

Captures multiple samples from the ADC.

Uses FIFO to capture samples from ADC. The valid channels are 0 to 3.

Parameters

channel	Number of the ADC channel (0 to 3).
buf	Pointer to buffer that receive the captured samples.
size	Number of samples to capture.

Returns

Mean of all sample values, in Volts.
