I'm thinking about making a controller for SK6812 Individually addressable RGB+W Led strips, perhaps something I can run on a Raspberry Pi. I'm curious if anyone has any example routines that do the output timing for Individually addressable LED strips?

I got my Raspberry pi working with the user space library written in C: at https://github.com/jgarff/rpi_ws281x with python and got my LED strip to light up with the examples. I also have FPC 3.0.4 installed on the pi. I would really like to be able to use the C library with FPC. I have some other C libraries that I’ve managed to use with FPC, but those were .dlls, but this doesn’t have .dlls. Would accessing this from FPC even be possible? And if so does anyone have an example of some C library that doesn’t have .dlls being accessed from FPC?
