Please forgive a new guy and his silly questions. I have not purchased the Peggy2, YET. I'm a model railroader and want to use P2 to display my turntable. I want a green display for available track configeration on at least four different turntables (selectable via an encoder switch). When selected and occupied by an engine, I want to track indicator (P2) to display red; or flipflop. I think I can do this through the code, but any comments or advise would really be appreciated. Thanks in advance.

Each location on the Peggy 2 only lights a single LED element. If you have three-pin, common-anode red-green LEDs, you can drive one by taking up two column-locations in a single row.

Or, if you are wiring the LEDs off board, there's no problem interleaving red and green LEDs-- just keep the total number of LED elements at 625 or below.
