I’ve been trying to write what I assume is a pretty basic mapping to have a hollow rectangle where every LED is somewhere along one of the edges (although I’d like to skip the actual corners I think?). I want to be able to specify the index where each side begins, which I guess would just be 3 variables, since side 1 can be assumed to begin at 0. I don’t want it to just have a width and height variable because the sides don’t quite have an even number of LEDs.
Unfortunately the mapper gives less informational error messages and I usually get to a point where my code can’t be saved because it has an error, but I can’t figure out where the error is. So I don’t even have the code from my latest attempt.
