To try and fault find i have stuck leds on my outputs porta 0 1 2. And wrote a program to light them one at a time with a 1sec delay. Even this doesnt work. One of the leds doesnt light one stays on at half brightness and the other led does what it should. Can anyone see why this program isnt working.
