Thanks for the quick reply.
I understand I shouldn’t have it connected to the car when I upload the sketch, but I’m not sure why I can’t monitor it afterward. I would only receive RX from the car, and TX to the computer. I won’t be entering any commands for the board to receive, and nothing in the sketch will transmit to the car. I just want to watch the communications between car components at this point.
Also, I have two arduinos, I don’t know if that would help anything.
okay, I see the problem after trying to run a quick test on the ardunio, the ardunio doesn’t like communicating with the computer @ 8192 baud. It’s not on the list in the monitor so it gives me a bunch of gibberish.
