Well, I got mine together and i gets as far as the ISO 9141 init screen which then fails. My car is a 1995 Subaru Legacy Outback (yes it's OBD-II, an early one) and since it is so early I'm wondering if it needs the L-line as well, I remember reading earlier in the thread that it may have been used early on. I'm going to try jumpering the L to the K. Froggy, need someone else to test your code?
I built my Obduino with an iDuino (and the Freescale chip for ISO) so I was wondering how I would power it since it has no 9v pins. What I ended up doing is taking apart a car-USB adapter and connecting it to the 12v at the OBD-II plug and the 5v at the iDuino. It seems to work but I it seems to be a very dirty signal, I see it in the LCD. Any suggestions on cleaning up the adapter or should I just build a power supply for it.
Great work guys,
Matt
