What is a Bus? A bus is a common communication line for transmitting information between various functional components of a computer, consisting of a bundle of wires. In fact, a bus is an internal structure that serves as a public channel for information transfer between the CPU, memory, input, and output devices. To simplify hardware … Read more
Comparison and Analysis of Embedded System Communication Protocols In embedded system development, these six major communication protocols each have their strengths: UART, with its simple and user-friendly characteristics, is often used for short-distance (1m) debugging communication between MCUs and sensors; RS232 achieves a stable 15m connection with host computers through level conversion chips, making it … Read more
The CAN protocol and MODBUS protocol are among the various protocols frequently used by engineers. Today, let’s take a look at the differences between the two. CAN and MODBUS are two communication protocols widely used in industrial control, automotive electronics, and other fields. They have significant differences in design goals, communication methods, and application scenarios, … Read more
I am a man in flip-flops, a long-term automotive electronics engineer in the magic city. As usual, I will share a piece of text I like to avoid becoming an engineer with high knowledge but low culture: After taking a shower on the weekend and changing into a new outfit, I went out but didn’t … Read more
Fundamental Concepts of Communication Signal: The physical representation of information (voltage, current, light, radio waves). Transmission Medium: Wires (single wire, twisted pair, coaxial cable), PCB traces, optical fibers, air (wireless). Data Frame/Packet: The basic unit of structured transmission (start bit, address, data, control information, checksum, stop bit). Baud Rate: The number of signal changes per … Read more
Introduction: For the scenario of controlling ECU power with the TJ1043 chip (pulling the INH pin high to wake up the ECU), combined with Vector AUTOSAR to achieve the requirement of “waking up only on network management messages”, the following is a step-by-step solution and code logic.。 1. Hardware and Requirement Analysis TJ1043 Features: Detects … Read more
