Function Documentation

uint16_t analog_read

(

uint8_t

channel )

Read analog value from saved result array.

Parameters:

channel

Channel to be read

Returns:

analog reading, 10-bit right aligned

ISR	(	ADC_vect	,
		ISR_NOBLOCK
	)

Analog Interrupt.

This is where we read our analog value and store it in an array for later retrieval
