Hello, i have the kit sparkfun multi-protocol OBDll with STN1110 but i can not establish communication KWP. I dont know how to do that.
I did some simulation tests, using an oscilloscope and realized that when sending commands to the ECU nothing comes out of the port ISO_K_TX or ISO_L_TX, the only thing that comes out of the port is a 25ms change line status(i think is some kind of wakeup).
So my conclusion is that maybe I am not correctly setting the STN1110.
- Can anyone provide a guide on how to start the simulated communication (without ECU)
with each protocol available on board?
- Does anyone here have experience with this IC?
If anyone can help me I would greatly appreciate, thanks.:wink:
