If the difference is positive and larger than a certain minimum voltage, then the signal is 1, and if the difference between them is negative, it will be 0. This two wires act as a differential line where CAN signal is represented with the potential difference between them. ![]() ![]() While Data is the message content to be sent, usually in 0 to 8 bytes length.ĬAN Protocol consists of two wires : CAN_H and CAN_L to send and receive the message.
