after playing with an arduino uno i want to read out the can messages from my car. I bought the Can-Shield 2.0 and a db9 to odb2 cable.
I used the seeduino library and the example codes and the serial monitor says that the init was successful.
After starting my car I don’t see andy messages in the serial monitor.
I searched a lot about my problem and I found out, that if I want to connect the shield to an existing can than I have to cut the p1 section on the back. Was that right?
I hope that anybody can help me.
