Write once, run on every boards: portable mruby
summary
Claims that one mruby program can run unchanged on multiple microcontrollers by splitting device-specific C glue from common Ruby behavior. Implements examples on EV3 and GR‑Peach (STM32 family under the hood), using an embed/middleware layer, two sensor types (PIR motion and ultrasonic distance), and two motor styles (angle servo and DC timed drive). Provides unified sensor/motor APIs, shared Ruby code, and working demos with a few live hardware swap hiccups.
