Hello. Maybe someone else works on things like this? I basically know how those are controlled, however I'm unsure what should I choose. Maybe SPI, maybe I should bitbang GPIO for clock / data? Last should work with that specific model (WS2801). Others use weird protocols (or "protocols"). I guess I should just try something. I just let people know that I'm working on that. I won't be surprised if I'm the first one to get it working. I'm also aware that this platform contains PRU's, which are maybe better for this task. Though, that seems like even more complex task. Like how to get code compiled for that (there seems to be one open way for C), how to get it running there and how to assign IO pins.
