NeoPixel Rainbow
demo Open · freely redistributable
An original CC0 bare-metal Adafruit Metro M4 Express program written for emulators.org and compiled with clang for thumbv7em (ARM Cortex-M4). It bit-bangs the single WS2812 NeoPixel on PB22 with a smooth rotating rainbow, blinks the D13 LED (PA16) as a heartbeat, and prints each new colour name over the SERCOM3 USART. Drives the real WS2812 line protocol and the real SERCOM3 TX directly, no runtime.
