Lisa M is available there :


As you seem to be a ws2812 expert and I didn’t take the time to watch into details into the specs :

Is there a chance that I can make it work without using too much cpu time ? My idea is just to change the color from time to time for instance when the battery gets low.

If I understand well, I just need to send the color I want once and it will not use any cpu time until I want another color. Am I right ?

I have bought one of those :

I will try to make it work with my lisa board to make something similar to the DJI stuff.

But before I start, I want to make sure that none has already done it…or have you ?


I wrote an Arduino driver for the WS2811 (at a glance, looks identical) which might help:



Note: not designed to work with standard arduino SDK (which sucks), but instead my own, which is in that repo.
