The CAN bus speaketh

A project log for CAN-obd2

This project was started as a way to display and save information from my 2008 Honda Civic's OBD2 port.

There's a wonderfully simple app for android called BlueTerm. I'm using it to pipe all the data from my LPC11C14 through the HC-05 bluetooth module onto my phone, where I have the ability to just store all of it. Damn that's just too easy now isn't it? I'm going to start using these HC-05 devices everywhere.

So far I haven't been able to get my car to respond to any queries on the CAN bus, but I can listen to everything it is saying at the least. Here's a quote:

Well hot-diddly-damn, I don't know what any of that means. I've got plenty of MegaBytes of this stuff sitting in BlueTerm logs on my phone and computer though. What's next?
