What is BUS Systems And Why Required? In past electronic devices in vehicles are connected via point to point wiring system. More Electronic in vehicle which resulted in bulky wire harnesses that were expensive and heavy too and if new nodes need to be introduced, it will be very difficult and complex. In electronic systemsContinue reading “Vehicle Bus System & CAN Protocol Part-1”

Types of CAN Communication Protocol High-Speed/FD CAN: High-speed CAN is by far the most common physical layer. High-speed CAN networks are implemented with two wires and allow communication at transfer rates up to 1 Mbit/s. Other names for high-speed CAN include CAN C and ISO 11898-2. Typical high-speed CAN devices include antilock brake systems, engineContinue reading “CAN Protocol Part-2”

Message Addressing And Identification It is worth noting once again that there is no explicit address in the CAN messages. Each CAN controller will pick up all traffic on the bus, and using a combination of hardware filters and software, determine if the message is “interesting” or not. In fact, there is no notion ofContinue reading “CAN Protocol & CAN FD Part-3”
