Profile

I made a Matrix chat client for my 2001 BMW infotainment system using Kotlin, Jetpack Compose, a Rasbperry Pi, and a custom PCB I designed to plug into the factory wiring harness: https://e39.dev/hmi/Matrix/Matrix.htmlI used Compose MPP cross-compiled to a Raspberry Pi (running Raspbian) to make my own Infotainment system from scratch. It works on the 2001-vintage factory BMW display with a retractable screen that has a cassette deck behind it.I then wrote a Matrix Chat Client for the system. The only input device (no touch screen) is a rotary knob that can be pressed. The knob events are sent via the car's IBUS serial bus, which I integrated into the Compose MPP UI state https://e39.dev/hmi
