Read an amplified sound level

This program will read the output voltage of a microphone amplifier connected to analogue input pin C.0 and report the value read in the 'b1' variable. The voltage output from the amplifier must be between 0V and V+.

Code Example:
main:	readadc C.0, b1		; Read the amplifier output analogue value
	debug			; Display the value
	pause 1000		; Wait a while
	goto main		; Repeat
