Has anyone tried to use OBD2 connector on their car?
I was thinking it would be an awesome project to connect FEZ to your car and then display read some info, like speed, pressure…etc. and log these on an SD card.
I’ve heard (on the interweb so of course it’s true ) that the ELM327 is a Atmel CPU with a custom firmware loaded, and therefore if you can figure out the protocol you are probably home and hosed.
Not that i’m interested in the at all, but i have seen many projects in the elektor (http://www.elektor.com) about this topic, this last year or so.
When i’m not mistaken some of the articles are also explaning how that protocol works.
My dad has a OBD2 set for different cars. Might be an idea to start developing with this.
We will have to work together though. Can’t do this on my own.
