This page describes how to set up R2P2 and provides general information about its usage.

Laptop Security Settings

If your laptop is configured to prohibit writing to USB memory devices, likely due to your company’s security policy, it will not function😣

Mac Issues

  • From our experience, Mac laptops occasionally encounter issues during the workshop
  • We are unsure of the specific models that may have problems. Both Intel Macs and M1/M2/M3 Macs have had issues in the past
  • Please be aware that we will not be able to know if your Mac will work until the day of the workshop

Install R2P2 into Raspi Pico

  • Download the latest R2P2-PICORUBY-*.uf2 from GitHub https://github.com/picoruby/R2P2/releases (Of course, unzip it)

  • Connect Pi Pico and PC while\npressing the BOOTSEL button. Then you’ll find RPI-RP2 drive in file manager (File Explorer or Finder)

  • Drag & drop R2P2-*.uf2 into RPI-RP2 drive

  • You’ll find “R2P2” drive (sometimes naming the drive fails and it shows “USB Drive” or something like that. But it would be working anyway)

  • Open a proper serial port on the terminal emulator

    Information about terminal emulators can be found in /terminal-emulator.

  • If you could see a screen like this, congrats, now you are at the gate🎉

    • R2P2 shell is a Unix-like shell, so you can use commands like ls, cd, cat, rm, etc.
    • irb command starts an interactive Ruby shell

  • Lastly, we would like you to stargaze at the picoruby/picoruby repo🌟
