This is the code for the Pico Light Arcade game that can be seen here: https://twitter.com/ghidraninja/status/1422900329369178113

Hardware setup

The LEDs and buttons are connected in a 3x7 matrix. Pictures will follow shortly :)

Required materials

  • A board (duh!)
  • 20 arcade buttons (note that most of them are really dark at 3.3V, you might want to change the resistor!)
  • Blade receptables
  • Wire
  • A Raspberry Pi Pico

LEDS

The anode is the Y axis, and gets connected to IO 0, 1 and 2.

The cathode is the X axis of the matrix and gets connected to IOs 3-9.

Buttons

The buttons' matrix Y axis is connected to IO 10-12, the X axis to IO 13-19.

LED/Button schematic

This is how the LEDs & Buttons neeed to be connected (With Buttons starting from IO10 instead of IO0):

Building the firmware

export  PICO_SDK_PATH=path-to-sdk
mkdir build
cd build
cmake ..
make

Running the webinterface

Note that you'll need a self-signed cert + key for running locally, as browsers only allow Web Serial via HTTPS.

cd web
npm install
HTTPS=true SSL_CRT_FILE=cert.pem SSL_KEY_FILE=keynp.pem npm start
