A sample mruby/c project for Raspberry Pi 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-3.3.0

• Clone this repository

  git clone --recursive https://github.com/picoruby/mrubyc-pico.git # Don't forget --recursive
  cd mrubyc-pico

• Build with cmake and make

  cd build
  cmake ..
  # cmake -DCMAKE_BUILD_TYPE=Debug .. # You can debug with picoprobe
  make

  Now you should have l-chika.uf2 file in build directory.

• 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 l-chika.uf2 into the drive
  • The LED on the Pico will start blinking. If not, you missed something

"l-chika" ?

It means "LED blinking" in Japanese.
