Ford Mustang (S550) CAN Bus Research & Scripts

This repo serves as a compendium of scripts and hours of trial/error research to try and map the S550 canbus, specifically towards the IPC.

Main Scripts

s550_cluster.py <game> - Currently supports Forza Horizon 5, American Truck Simulator & Euro Truck Simulator 2 in an alpha state. Allows that game to interface with the cluster. See s550_data.py for the model in translating other game data
- Video Demonstration
interactive_brute_force.py - This script allows you to use the up,down,left,right,enter keys to control the menu on the cluster
- arrows.py and brute_force.py were merged into a single interactive script
- Video Demonstration

Supporting Scripts

ports.py - Script that was pulled from StackOverflow to show which port the USB-to-CAN interface is running on. Required to communicate with the IPC
decode_can_log.py - Takes a CANdump from the can folder and converts the b64 data string to a more easily readable byte array
replay.py - Attempt to replay data from the CANdump at a slower pace to determine functionality (doesn't quite work)

Requirements:

USB-to-CAN adapter. I am using a CANable
Wires / Breadboard Wires
12v power supply (I had one laying around with a 5.5mm x 2.1mm plug barrel on the end)
- You can wire one of the female connectors from here to allow for easy plug and play.
S550 Cluster (you can find them for under $100 on eBay.)
- I am unsure of the digital clusters functionality, some data should be shared so it should work in an alpha state.
Python, PIP, & Packages in the requirements.txt file
