Over-engineering an RGB LED strip: let’s make a custom programming language

This is nice. I once tried to get programmatic animations running on MicroPython, but it seemed to fail to load even the simplest color conversion class (I didn't have an ESP32 back then).

I also tried streaming patterns (could've been really cool to hook it up to something like ColorCord), but my Wifi connection was definitely also too unreliable for that (hmmm, what about PoE LED strips?).

There's some project based on Javascript (I think) with in-browser previews for the patterns, but it's proprietary and only sold as pre-flashed modules. I forgot the name, but I think it has been posted here.

This bytecode-custom-language solution definitely looks over-engineered (wish I could use a language I already know to make an animation), but damn, it should be efficient. I think I'll play around with it bit.

That would be the PixelBlaze from https://electromage.com/

... and it's super-duper-amazing for actually finishing LED projects. While the code on the ESP32 is proprietary, everything else is very open and the community is awesome.

If your name is Sisyphus or you just want to hack on LED electronics and maybe make some lights blink, anything else is fine.
