I need help with my BM Trike! We have put WS2801 LED strips on in a non rectangular order.I have put together a matrix table (stealing code from lots of other people on this group!) that I am trying to use so that we can get the LEDs to light up in order from the front to the back of the trike in a sweeping sort of motion. But for the life of me I cannot figure out how to access the table correctly. This is the code I currently have. When I use the fill rainbow function, it does fill the LEDs with rainbow colors, but they are not in the right order. Any help would be appreciated. I am really out of my league, but am desperately hoping to get this done so that we are not darkwads!
