1. Introduction to CAN In automotive electronics, there are many ECU control modules that manage different functions. To enable these numerous ECU modules to work together, the CAN protocol was developed, allowing multiple ECU modules to be connected to the CAN bus for local area network communication between ECUs. CAN is a serial communication protocol … Read more
The CAN (Controller Area Network) bus protocol defines four basic frame types and one inter-frame space, which are used for data transmission, error handling, bus load control, and other scenarios. Below is a detailed explanation of the structure, function, and practical applications of each frame type: 1. Data Frame 1. Function Core Purpose: Transmission of … Read more
