Thu, Jun 18th 6:27pm 2009: Practical Arduino
Originally posted on Practical Arduino Just made a big step forward in the Car Engine Datalogger project with an ELM327 interface chip connected to the second serial port on an Arduino Mega:
I can now issue data requests from the Mega and read the return value back from the engine management system via the ODB-II interface.
One step closer to moving my whole vehicle remote control / datalogging / diagnostics system over to running on an Arduino :-)
There's some information about my current system at www.geekmyride.org/wiki/index.php/Jon's_RX-8 but hopefully that will soon be largely obsolete.
