Computer engineer and Adafruit customer, Paul Bartek, created a tutorial to Display realtime engine data on PiTFT touchscreen displays for Raspberry Pi With RaspberryPi
A couple of weeks ago I released a tutorial demonstrating how to turn your
Raspberry Pi and aftermarket head unit into an advanced display for your
This week I will be showing you an affordable and practical alternative than
using an aftermarket head unit to display your data.
Here’s what I came up with! The program will connect through the OBD-II
interface, display the gauges available dependent on the particular vehicle
and display realtime engine data on Adafruit’s PiTFT touchscreen display
in an interactive GUI.
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
I took a fork of pyOBD’s software from there GitHub repository,
pyobd, and used this as the basis for my program.
