CAN Bus and CANopen Protocol in Practice

The article explains the CAN bus and CANopen protocol commonly used in industrial settings, covering frame formats, arbitration mechanisms, the object dictionary, SDO/PDO transmission, and heartbeat network management. It includes transmit and receive code for STM32F407 with a TJA1050 transceiver, a Linux SocketCAN integration example, and engineering experience and troubleshooting methods such as 500 kbps baud rate configuration, 120-ohm termination resistors, and CAN FD at up to 8 Mbps.
