Introducing Rubyduino, a Ruby to Arduino UNO compiler based on Matz's Spinel!

Rubyduino compiles Ruby sketches for Arduino boards and uploads the generated firmware. Under the hood it uses Spinel , a Matz's Ruby AOT compiler, vendored at a pinned revision. How it works? Rubyduino adds a small Arduino runtime on top of that C code. Functions like digital_write , delay_ms , analog_read , serial_print , and pulse_in are mapped to small AVR C functions that talk directly to the Arduino UNO hardware registers. After that, the normal AVR toolchain takes over: Ruby sketch Spinel
