OBD-Pi: Raspberry Pi Displaying Car Diagnostics (OBD-II) Data On An Aftermarket Head Unit #piday #raspberrypi @Raspberry_Pi

Thanks to Adafruit fan Paul Bartek for sending in his great project! Check out the full tutorial here.

I am a senior majoring in Computer Engineering from Chicago, Illinois. I follow your Rasp-Pi, BBB and Arduino blogs on a daily basis! I thought I would take a shot at creating a Raspberry Pi Tutorial / Blog.

The tutorial that I am sending in titled “OBD-Pi” is how to turn your Raspberry Pi & aftermarket head unit into an advanced display for your vehicles engine data.

pyOBD (aka pyOBD-II or pyOBD2) is an open source OBD-II (SAE-J1979) compliant scantool software written entirely in Python. It is designed to interface with low-cost ELM 32x OBD-II diagnostic interfaces such as ELM-USB.

I took a fork of pyOBD’s software from there GitHub repository, https://github.com/peterh pyobd, and used this as the basis for my program.

The program connects through the OBD-II interface, displays the gauges available dependent on the particular vehicle and displays realtime engine data to the cars aftermarket head unit in a interactive GUI.

I would be ecstatic if this made the Adafruit Blog under the Raspberry Pi category!
