V-Link - Raspberry Multimedia & CAN Interface

Hello!

Maybe some people already know my project from the swedespeed forum or reddit posts.

V-Link (formerly RTVI) is an automotive interface to retrofit older cars that already had some sort of MMI. My goal was to upgrade my car with Apple CarPlay as well as some more information when it comes to engine temps, boost pressure etc but the classical Need for Speed gauge was a little too much for me so I tried to keep it as OEM as possible. It's been in development for over 2 years now.

In the current form the project consists of two parts: an open-source app that runs natively on raspberry and a custom hat that I designed in my freetime which builds the interface to the car. The hat has dual-can, lin, serial out to control the screen mechanism and an ADC interface to connect external sensors like a combined oil temp/pressure sensor from Bosch. Its not needed and the circuit can be build from scratch but the installation just gets that much simpler.

The app supports Apple CarPlay and Android Auto at 60fps, live CAN-data as well as rich settings to customize the gauges and data to your needs. The CAN-data can be enhanced with additional codes or completely altered for any brand or model through an exposed settings file. It runs natively on Raspbian OS so you have full access to a completely customizable experience. No need for any Android or Custom images.

Currently the CAN communication is configured for P1 T5 models but some folks from the community are already looking up the codes for D2, D5 etc
