OBD II and a Pic 877 toy/ford/dodge etc
Hello everyone, havent been here for a while :sick:
Anyway ive been searching and reading everywhere trying to figure out how to possibly get my Pic 877's to communicate with my obdII on my toyota. I also have other cars i would like to do it with but for now the toyota is the probem (1996 camry)
Im pretty good with a pic, i can do basic stuff and debounce pull up and stuff like that, ive also gotten it to communicate via rs232. My language is C.
How would i get the pic to communicate with the obd2 system ? What protocol is it ? in my naive head im thinking that some how i can hook up a few wires from a port on my pic to my obd2 and send data to that wire (like serial) and reset and or read the codes.
I would be happy with something that blinks a light as to the codes, like 234 would blink twice stop blink three times stop then blink four times stop.
Once (if) i can get it to communicate i can work making it better.
Thanks in advance !
