This tutorial will cover more advanced uses of the WS2812/NeoPixel LEDs with a PIC. For a different project (which itself is yet another nested sub-project… 😉 I was working on a variation of the mechanism I used to generate the WS2812 bitstream in Madison’s NeoClock. This new approach still uses the PWM and DSM modules as before but drives it with the PIC’s EUSART instead of the assembly-coded-bit-banged-PWM-edge-hopping contraption used in the clock.
