Hello, I need some help.

I am using the CAN-BUS Shield v1.0 with the Arduino Uno R3.
Uploaded the receive_check example of the library and connected the shield with the cars CAN-H and CAN-L.

The Rx LED ist blinking, but i dont get any information on the serial monitor. CAN BUS Shield init ok! and the rest of the debug messages will be displayed.
The correct BUS Speed is selected.

Thanks in advance! Best regards from Germany.

I’m not sure what library you are using, but I know this one works for sure.

I have NO RX and TX blinking :frowning: Power only. How to debug?

This might be related to the termination being present. Try removing the termination jumper or the resistor.

I have more details in this post: viewtopic.php?p=18878#p18878
