On-board data bus technology is the interconnection technology used for onboard devices, subsystems, and modules. Understanding it from a computer perspective, various avionic devices are akin to individual microcomputers, while the bus serves as the channel and link connecting these microcomputers, forming a complete functional network for avionic equipment. Traditional bus technologies, represented by MIL-STD-1553b … Read more

5. Short Circuit of CAN L to Power (Positive) When a short circuit occurs between CAN L and the power (positive), due to the fault tolerance characteristics of the CAN bus, the entire CAN network may be unable to communicate or generate related fault codes. Because of the short circuit of CAN L to the … Read more
1. What is CAN Bus? CAN stands for Controller Area Network, developed by the German company BOSCH, known for its research and production of automotive electronic products, and has ultimately become an international standard (ISO 11898). It is one of the most widely used field buses internationally. In North America and Western Europe, the CAN … Read more
When connecting a microcontroller to sensors, displays, or other modules, have you ever considered how the two devices communicate? What exactly are they saying? How can they understand each other? Communication between electronic devices is like communication between humans; both parties need to speak the same language. In electronics, these languages are called communication protocols. … Read more
The integrated network of air, space, and sea is based on ground networks, supplemented and extended by space-based, air-based, and sea-based networks, providing ubiquitous, intelligent, collaborative, and efficient information guarantee infrastructure for various network applications across wide spatial ranges. In the integrated air-space-sea network, the air-based network consists of high-altitude communication platforms, drone self-organizing networks, … Read more
In embedded development, you must have encountered various buses, including address and data buses within the chip, high-speed and low-speed buses, as well as various communication buses outside the chip. However, it seems that people still do not have a good grasp of buses, so today I have selected an article about buses for everyone … Read more
