Using Dracosb UFC OLED code, I added in the two comm channels to his multiplexer scheme, and have all displays running off one Uno using IC2.
Top display is Comm 2, then scratchpad, then the 5 option screens and the last one is Comm 1 - all hooked up via the multiplexer.
Going to make a circuit board to get rid of as much spaghetti as I can when I move it to the UFC.
Here is the code - if you are using dracosb's code for the switch matrix, you would have to cut and paste into this one - as I removed it since I am using a BBI-64 for everything else in the UFC.
