Types

type ADC

type ADC interface {
	pin.Pin
	// Range returns the maximum supported range [min, max] of the values.
	Range() (int32, int32)
	// Read returns the current pin level.
	Read() int32
}

ADC is an analog-to-digital-conversion input.

type DAC

type DAC interface {
	pin.Pin
	// Range returns the maximum supported range [min, max] of the values.
	Range() (int32, int32)
	// Out sets an analog output value.
	DAC(v int32)
}

DAC is an digital-to-analog-conversion output.
