CircuitPython Joystick controller for KevsArcade

This is a simple CircuitPython script that reads the analog joystick and buttons on a 2-axis arcade joystick and sends the data to a computer over USB. The computer can then use the data to control a game or other software.

The script is designed to work with the KevsArcade project.

Hardware

The script is designed to work with the following hardware:

• KY-023 2 axis joystick module
• Raspberry Pi Pico
• 2x Arcade buttons (Pimoroni)

Installation

1. Install CircuitPython on the Raspberry Pi Pico (Thonny can make this easy)
2. Copy the code.py file to the Pico - this will automatically run when the Pico is connected to a computer
3. Copy the boot.py file to the Pico - this will automatically run when the Pico is powered on and set it as a USB HID device
4. Copy the hid_gamepad.py file to the Pico - this is a library that allows the Pico to act as a USB HID device
5. Connect the joystick and buttons to the Pico as shown in the wiring.jpg file
6. Connect the Pico to the Raspberry Pi using a USB cable
