IF-THEN issue

[jmgelba]

Jump into the subrountine, run that code once, jump out, if the pin turns low, the led stays on because the IF THEN code isnt being run. Therefore there has to be IF THEN code in the main program loop to detect if PORTB.7 = 0 and turn off the LED and send 0 to the POT.

Very interesting. In your main code you have an IF statement to detect PORTB.7 =1 and another IF statement to detect PORTB.7=0.

or you could just call the subroutine from the main program as it does both checks.
