Im using GPIO 4 and 5 to drive a tri colour LED.
The problem is GPIO 5 never goes high, it hovers around 0.1V.
Port 5 is declared as an output and im setting it high but its not turning the LED on.
GPIO 4 works fine.
I know its not my circuit because when I short pin 5 high using a peice of wire, the LED comes on.
From reading the datasheet there doesnt seem to be anything special about port 5.
My chip must be broken ?? Right??
