Is there a program that would let me turn the bits of an LCD controller on one at a time? I have a few controllers and I'm not sure of the pinout. I figured if I could make the outputs go on one at a time I could identify the pinout. Like leave the red and blue display data off and then turn on the green bits one at a time and so on. It would really help me match up some of this junk I have laying around here.
