Hi all:
Since the ws2812B require 1 uSec/bit pulse rate, I hope to control it via a PIC 12F1822 @ 32Mhz or 8Mhz per ASM instruction.

Has anyone done any work in this regard?
thx

If you google there's a number of examples (I was looking at playing with them, but haven't got round to it yet).

However, the same examples explain how the timing isn't at critical as it sounds.

I was thinking along the lines of a dedicated loop to time slice the hi/lo logic in the 1 uSec and to use the 50Usec gap between LED signals to fetch/calculate the next set of 24 bits.
