Function Documentation

initAnalogOutput()

void initAnalogOutput	(	AnalogOutput *	analogoutput,
		const char *	name,
		int	hz,
		int	channel
	)

Initializes an analog output.

Parameters

output	Pointer to the AnalogOutput structure to initialize
name	Name of the output (string)
hz	Sampling frequency in Hertz
channel	ADC channel number for the output (0-16)

This function initializes the base output properties, sets the ADC channel, and configures the corresponding GPIO pin based on the channel number.
