Smiley Buttons
demo Open · freely redistributable
An original CC0 bare-metal micro:bit v1 program: it enables pull-ups on the button pins (P0.17 / P0.26) and reads them from the GPIO IN register, showing a neutral face by default, a happy face while A is held and a sad face while B is held. Exercises the real button hardware path.
