- CAN bus is a message broadcast type of bus, and the pre-defined data frame is called a CAN message. The broadcasted messages are heard by all the nodes on the bus. Keep in mind that it is an asynchronous protocol, and all the nodes have to operate on at the same baud rate to communicate with each other.

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 ...
