Functions

  • PS/2 keyboard key detection (US layout) (2 keys are not supported: Pause/Break, PrintScreen)
  • Print key info via serial (UART, with TX pin 0, RX pin 1)
  • LED flashing depending on USB connection.

Setup

  • Connect the Pico to your computer in BOOTSEL mode (connect while holding the button)
  • Copy the ps2_macro_keyboard.uf2 file to the RPI-RP2 drive
  • Connect the PS/2 socket (mini-DIN 6P) pin 1 (data) to GP17 and pin 5 (clock) to GP16.
  • Connect the PS/2 socket pin 3 (ground) to any ground on the Pico.
  • Connect the PS/2 socket pin 4 (vcc) to Pico physical pin 36. It is important to NOT connect it to 5 volts, else it will fry your Pi (The keyboard works perfectly with 3.3 volts as well!)
  • The onboard LED should start flashing, indicating a connection.
  • Optional: To see serial output, connect USB to TTL adapter RX pin to GP0 and TX pin to GP1 (this is not reversed, TX goes to RX, and RX goes to TX)

Build

0 - Pico SDK installed and set up - see raspberrypi/pico-sdk
1 - Clone this repo. I'm kinda new to Git, I used some other repos and have a .gitmodules file, but I don't know if it works.
2 - Create a new build directory. (I needed to force push my local repo, so my build directory is pushed)
3 - Run cmake .. and make
4 - Copy the .uf2 file to the Pico in BOOTSEL mode
