Matrix Animation
demo Open · freely redistributable
An original CC0 bare-metal Calliope mini program written for emulators.org and compiled with clang for thumbv6m (ARM Cortex-M0). It configures the LED-matrix GPIO and scans a big heart alternating with a small heart across the real 3x9-multiplexed matrix (wired exactly like the micro:bit v1); the board integrates the scan into the 25-LED image. Drives the display hardware directly with no runtime.
