RobG 1,892 Posted March 14, 2012 Share Posted March 14, 2012 Here's a nice project idea, MSP430 based OBD-II reader. Ever since my car's "Check Engine Soon" indicator started to light up, I wanted to buy or build my own OBD reader to see what's going on. I am thinking something simple would do the trick: MSP430, small LCD, and a couple of opto-couplers. This shouldn't be too hard, though there are several standards involved. Has anyone done anything with OBD? I would take that on, but I have several things in progress and just don't have enough time. Some useful references: Wiki OBD-II site OBD-II protocols Vehicle database Quote Link to post Share on other sites
