Here I have used a CAN BUS Dongle from Waveshare to read CAN BUS data from the OBDII port.
You can see it in action here:
And find more info in my Github here:
Next is reading and clearing of DTC error codes.
Enjoy.

I can highly recommend PyOBD. It also features live data and graphs. It can also read and clear fault codes:
There’s also a video on this:

Thank you. To be honest I did not even look for other programs and created my own. The only difference with the PYobd is that it reads of the slower serial communication whereas I am reading the CAN BUS port. Plus I like to create my own programs so I can make them look as I want. But for other people it might be the better way. Have the DTC error reading and clearing done too. Now I could create some gauges maybe, although I have enough CAN BUS gauges that I also have built in my car. Next step will be hardware, Either create a whole expansion port PCB or make a tiny CAN BUS reader that connects to the USB hub I already have in the uConsole. Appreciate your comment though, thanks.

Super cool! I still hadn’t considered the possibility of using my uConsole as a CAN analyzer… great work!
