Basic Principles
CANbus is a multi-host protocol, which means that any device (node) can send and receive messages on the bus. Messages are sent by broadcasting, and all nodes can receive and decide whether to process these messages.
Communication Methods
- Message Frame: CANbus uses standard frame and extended frame formats. Standard frame has an 11-bit identifier, and extended frame has a 29-bit identifier.
- Data Rate (Baud Rate): CANbus supports multiple data rates, the most common ones are 125 kbps, 250 kbps and 500 kbps. The maximum can reach 1 Mbps.
- Data Length (DLC): Each CAN message can contain 0 to 8 bytes of data.
- Main Features
1.Real-time: CANbus has high real-time performance and is suitable for delay-sensitive applications.
2.Error Detection and Handling: CANbus has powerful error detection and handling mechanisms, including CRC check, bit stuffing, confirmation errors and form errors.
3.Multi-master architecture: Any node can send messages, and there is an arbitration mechanism to determine which node has priority on the bus.
4.Reliability: CANbus performs well in noisy environments and is widely used for communication between automotive electronic control units (ECUs).
