A controller area network ( CAN) is a vehicle bus standard designed to enable efficient communication primarily between electronic control units (ECUs). Originally developed to reduce the complexity and cost of electrical wiring in automobiles through multiplexing, the CAN bus protocol has since been adopted in various other contexts.
In this tutorial we explain the Controller Area Network (CAN bus) 'for dummies' incl. message interpretation, CAN logging - and the link to OBD2, J1939 and CANopen. Read on to learn why this has become the #1 guide on CAN bus. You can also view our CAN protocol intro above or get the PDF.

Feb 21, 2024 · CAN bus is an asynchronous half-duplex communication protocol, thus the CAN controller has TXD and RXD pins that are used for the transmission and reception of data, respectively. These pins are connected to the CAN transceiver for converting the digital signals to differential signals for the transmission of messages on the bus and vice-versa ...
