WS2811 and WS2812 One-Wire Communication Assembly Help

But in general is much easier to control as the timings are those of an SPI interface and can be really fast driven if you have the resources.

I had 3 in the parts bin , so I had a go using mssp module . @64mhz with the fastest spi clk its no problem at all .
a complete 3 led frame is less than 80uS . heaps easier than ws2812
