This repo contains all the information required to connect a Logitech G Driving Force shifter via it's serial DB9 connector and a USB Progressive handbrake to any Thrustmaster wheel with a 6-pin mini-DIN (PS/2) port via a RP2040. No modifications are required to any hardware maintaining full normal use.

The Shifter sends raw analog voltages for the 2 axis and a push button for reverse to the RP2040.
The handbrake communicates with the RP2040 via standard USB HID.
The RP2040 communicates to the Thrustmaster via I²C.

• Logitech G Driving Force shifter (For G29, G920, G923, etc..)
• Thrustmaster wheel with a DIN-6 (PS/2) port (T248, T300, etc..)
• [Optional] USB progressive (or digital) handbrake ./info/Ali Handbrake.png
• Male Serial DB9 cable ./info/DB9-pinout-diagram-345x.png
• Male 6-pin mini-DIN (PS/2) cable ./info/PS-2 Connector.jpeg
• Raspberry Pi RP2040 MCU waveshare.com/wiki/RP2040-Zero

• Solder Male Serial DB9 cable to RP2040 as per the following:

  Male DB9 Pin	RP2040 Pin	Description
  1	-	Not Connected
  2	31 / GPIO26	X-Axis
  3	39 / 5V	VCC
  4	20 / GPIO15	Reverse
  5	-	Not Connected
  6	-	Not Connected
  7	32 / GPIO27	Y-Axis
  8	39 / 5V	VCC
  9	GND	Ground

• Solder Male 6-pin mini-DIN (PS/2) cable to RP2040 as per the following:

  Male PS/2 Pin	RP2040 Pin	Description
  1	-	Not Connected
  2	7 / GPIO05	I2C SCL
  3	GND	Ground
  4	6 / GPIO04	I2C SDA
  5	37 / 3v3	VCC
  6	GND	Ground

• 1. Install VS Code: visualstudio.com/VS-Code

• 2. Install Pico VS Code Extension: visualstudio.com/raspberry-pi-pico
  Tutorial: raspberrypi.com/pico-vscode-extension
  (Optional) Install CMake Tools Extension: visualstudio.com/cmake-tools

• 3. Copy the .src/ directory to your computer and open it in VS Code.

• 4. Clean and Configure CMake using either CMake Tools or Pico

• 5. Build project and upload

• 6. Connect all cables and have fun :)

The idea to do this and a lot of the information came from:
