Talking to an automotive ECU

michinyon:
You said, you didn't see anything at all.

And then you said, some bytes are missing .

To me that seems inconsistent. Are you seeing anything happen, what do you see ?

If I run at the same speed as the Arduino emulator (7800 baud, but it's using the UART) I see nothing.

If I run at 9600 baud (emulator still at 7800) then I get data, but it seems corrupted.

Here's the emulator code I'm using:
