Reading OBDII Trouble Codes & Descriptions Using Python On A Raspberry Pi

[BirchJD]

I have written a Python script to read trouble codes from a car ECU and look up a human readable description for the codes. I will OpenSource the Python script on GitHub a bit later today here:

Following are some videos about the project:

The Raspberry Pi OBDII Python script is now communicating and getting all valid PID data using a Python Class. Source code will be updated on GitHub.

The OBDII Python application now has the start of a GUI added. The next update should have most of the GUI complete and a custom Raspberry Pi device to run on.

How can i get data from OBD2 to raspberry pi without using GUI.

I want to only script like below..

Rumee,

In GitHub you can view the commits to the project:

https://github.com/BirchJD/PiOBDII/commits/master

Get the code at one of the early commits, I think it was the second commit when I was just pulling back trouble codes.

i would like to build an OBD2 reader and am curious about what hardware is recommended. does this program have touch screen interface? is it ok to ask for hardware suggestion? can it send a audio alert when a error code is detected?

[BirchJD]

You just need an "ELM327 OBDII" device, search on eBay, there are lots of them and very cheap. This either connects to the USB, via WiFi or BlueTooth.

As for sending an audio alert, if you can program in Python, you can implement features like that.

The finished project with touch screen can be viewed on a video here:

My source code is OpenSource, you can find it here:

Thank you for your suggestions. I've bought one ELM327 OBD2 that connects via Bluetooth thanks to recommendations and useful advice from this post https://obdsolaris.com/elm327-definite-guide/
I think you guys should try out one for this case.
