Controller Area Network (CAN Bus)

It transmits data in frames, which consist of a header, data, and a checksum. The header contains information about the data, such as its length and priority, and the checksum ensures the data is transmitted correctly. Each device on the CAN bus can send and receive messages, and all devices receive the same messages. This means that devices can communicate and respond to each other’s requests in real-time, without requiring a central controller to manage the communication.

One of the most significant advantages of the CAN bus is its ability to handle multiple messages simultaneously. In situations where multiple devices are trying to transmit data at the same time, the protocol uses a priority-based system to determine which message takes precedence. Higher-priority messages are given priority, while lower-priority messages are delayed until the higher-priority messages have been transmitted.

The CAN bus is not limited to use in automobiles. It can be used in a wide variety of applications, including industrial automation, medical equipment, and aerospace systems.
