Rainbow (WS2812 hue wheel)
demo Open · freely redistributable
An original public-domain (CC0) program, compiled from freestanding C to a flat ESP32-H2 RV32IMAC image. It bit-bangs the on-board WS2812 RGB LED on GPIO8 and steps an Adafruit-style colour wheel so the LED fades smoothly through the spectrum. Real RISC-V machine code driving a real 800 kHz one-wire waveform, decoded from the GPIO edge timing.
