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!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
