A sample mruby/c project for Raspberry Pi Pico W

This repository is created just by tweaking mrubyc-pico.

Getting started

• Setup Raspberry Pi Pico C/C++ SDK

  • Follow the instructions on https://github.com/raspberrypi/pico-sdk#quick-start-your-own-project

    • Make sure you have PICO_SDK_PATH environment variable

  • https://learn.sparkfun.com/tutorials/pro-micro-rp2040-hookup-guide will also help you if you use Sparkfun Pro Micro RP2040

• Install mrbc (mruby compiler)

  rbenv install mruby-4.0.0

• Clone this repository

  git clone --recursive https://github.com/lumbermill/mrubyc-pico-w.git
  cd mrubyc-pico-w
  # If you forgot to add recursive option, run the following:
  # git submodule update --init --recursive

• Build with the rake task

  rake samples:led

  You should have led.uf2 file in build directory. rake -T shows the commands for other examples.

  The runtime sample (rake samples:runtime) builds a firmware that receives mruby bytecode over USB serial and executes it — no reflash required per run. This is a minimal proof-of-concept; the full-featured runtime implementation is maintained at lumbermill/prremote.

• Install

  • Connect a USB cable to Raspi Pico while pressing BOOTSEL button
  • You'll find RPI-RP2 drive mounted in your PC's filer
  • Drag and drop led.uf2 into the drive
  • The LED on the Pico will start blinking. If not, you missed something
