A YouTube video demonstrating the LIN Communication project.
DIY Project – LIN Network Interface for RealDash with ESP32
I developed my own ESP32-based module for communication with steering wheels that use a LIN network, such as the Jeep Renegade steering wheel. In addition to the hardware, I also developed all the firmware responsible for reading, decoding, and interpreting the commands sent by the steering wheel.
The system communicates directly with the LIN network, identifies the pressed buttons, and provides all the information in real time through the Serial Monitor. Furthermore, I created a custom XML for RealDash, allowing each button on the steering wheel to be used as desired.
With this solution, it’s possible to map functions such as volume, track change, media commands, call answering, custom commands, and any other function supported by RealDash. The user has complete control over the button configuration through the XML.
Project Features:
• Full LIN Network communication using ESP32
• Compatible with LIN steering wheels from Jeep Renegade and other similar models
• Serial monitor with real-time command identification
• Customized XML for integration with RealDash
• Free mapping of all steering wheel buttons
• Open platform for customizations and new commands
• Completely DIY (Do It Yourself) project
The goal is to allow anyone to reuse modern multifunction steering wheels in customized projects, digital dashboards, Android multimedia systems, and RealDash-based systems, without relying on expensive or limited commercial interfaces.
