Worked on some LED control junk again. Version 1 on the breadboard and then miniaturized into a wire.
This isn't my design, but it was a decent amount of fun anyway. It'll operate up to 50 WS2812 addressable LEDs using a fairly simple serial protocol as input. I drove a test LED (just one, because I was kind of dumb) from my bus pirate.
The original code, idea, etc... is here:https://github.com/TauLabs/TauLabs/wiki/PicoC-Project:-RGB-LEDs
I changed the protocol a bit because I wanted to be able to directly address LEDs at will instead having to communicate the entire state of the world on every write. (one line change)
