Hey Damage. Sounds great! Please keep us posted about your progress with lots of photos. For Game Frame, I’m just using one data pin (digital pin 6), and the grid zig zags from the top like this:
0 1 2 3
7 6 5 4
8 9 A B
F E D C
At 16×16, of course. Actually, it may start right-to-left on the top row… I have the final panel in route from China right now and will let you know when it arrives. I have versions of the firmware for both variations, since I’ve received both kinds.
