  • Car to Arduino Communication: CAN Bus Sniffing and Broadcasting with Arduino

    Hi Stvmac11,thank you verys much for sharing this very instructive tutorial!As other people, I also have the problem that while the CAN is correctly initialized ("CAN init ok") when hooking the OBD connector into the car and running the sketch (read_sample no filter), no CAN messages appeared on my console.Looking at the code, I was actually expecting a large amount of messages apparing on my screen.I took the sketch "as is" adding nothing, just compiling it and uploading it. Is there anything that we have to add (in the code) in order to start seeing the messages?Thanks in advance for your replyJonathan
