Tutorial

First of all, you should:

• Be knowledgeable how to install a UF2 file into Raspi Pico on https://www.raspberrypi.org/documentation/rp2040/getting-started/#getting-started-with-c
  • https://learn.sparkfun.com/tutorials/pro-micro-rp2040-hookup-guide will also be helpful if you use Sparkfun Pro Micro RP2040

Use a release binary

• Download the newest release binary from Releases

• Unzip it. You should get a file that looks like prk_firmware-0.9.0-20210910-xxxxxxxx.uf2

• Flash the uf2 into RP2040 in BOOTSEL mode

  

• PRKFirmware mass storage drive should be mounted, then drag and drop your keymap.rb

  

Your keyboard will automatically reboot. Enjoy!

Tip: RP2040 in which PRK Firmware is already installed can reboot to BOOTSEL mode by double-pressing the RESET button without detaching the USB cable.
