Cars

Repo Car Report Car report is an app I found around 2 years ago in F-droid. It is a simple app that helps you track your car expenses. It had an old UI but it had many features and it was really easy to use. I was really happy with the app, so I decided to investigate the app and found out that it was unmaintained since 2019 (officially since 2021)....

This post will cover my attempt of building a completely open way to read the OBD2 messages sent through the CAN bus of a car, and communicating with the ECU (Electronic Control Unit), basically “the brain” of the car. More will be coming :) Update on 2024-07-10 I’ve been working in this project since before writing this post, and there’s more info to share than I initially thought. I think a better way to share this is to write a series of posts, showing my progress and what I’ve learned so far....
