Creating my own "OBD-II reader" to access the CAN bus of a car
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....
