I wanted to find out if anyone has any interest in working on an AVR OBDII scan tool? I'm currently working on another project (writing new firmware for the Fantazein Clock to rx data over serial port to display new/stock/weather tickers :idea: ) but I'm thinking of trying to do this when I get done.
I'm really referring to the straight up OBDII from cars from 96 (some before 96, like mine)and later. I know there is a CAN version of OBD on some late model cars, but this isn't what I'm referring to. OBDII uses PWM, if I remember correctly, so reading that is the trick. As far as I know, most Atmel chips can do PWM, no?
Well, I wanted to start a thread and see if anyone might have any interest in it. The check engine light in my car came on the other day and I went and bought the Actron AutoScanner ($150 :shock:) and when I opened it up there wasn't much to it. Just a few buttons and an LCD. I'll probably return it since it's too expensive and I'd like to make my own. Of course, I'll try to gather some info on it first. ;)
