NeoPixel Rainbow
demo Open · freely redistributable
An original CC0 bare-metal Adafruit Feather nRF52840 Express program written for emulators.org and compiled with clang for thumbv7em (ARM Cortex-M4). It bit-bangs the single WS2812 NeoPixel on P0.16 with a smooth rotating rainbow, blinks the red user LED (P1.15) as a heartbeat, and prints each new colour name over UARTE0. Drives the real WS2812 line protocol and the real UARTE0 EasyDMA directly, no runtime.
