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!
