I tried this:
// like so
SPI1.send4bit([1,1,1,1,1,1,1,1, 1,1,1,1,1,1,1,1, 1,1,1,1,1,1,1,1], 0b1110, 0b1100);
This should turn the first led white, but did nothing :(
Is this wrong?
I also found this guide showing how to control WS2812 with PWM and DMA. This is a very efficient way, as they say. This guide is far beyond my understanding. Is something like this available with Espruino?
When I started this project, I thought that the LED part would be easy and fun. Already wasted four days on this problem, lol)
