In microcontroller development, many engineers choose assembly language for low-level programming to directly control hardware and execute commands efficiently. However, since assembly language interacts directly with hardware, it is easy to make mistakes. This article summarizes common errors in microcontroller assembly language based on the Keil C51 assembler environment, hoping to assist fellow engineers. 1. … Read more
It is said that learning microcontrollers involves four stages: 1. Beginner Stage: Understand the basic concepts of microcontrollers and their application areas, master basic electronics knowledge and programming knowledge. 2. Entry Stage: Choose the appropriate microcontroller and development board, set up the development environment, and conduct basic practice projects such as LED blinking and button … Read more
Book Giveaway at the End AI Agent has recently become extremely popular. Sam Altman once described the future of AI Agents: “Today’s AI models are the ‘dumbest’ they will ever be; they will only become smarter in the future!” Andrew Ng also praised at the AI Ascent 2024 conference: “This is the golden age of … Read more
The serial port is a commonly used interface in computers, with the most common being the RS-232-C interface. It was established in 1970 by the Electronic Industries Alliance (EIA) in collaboration with Bell Systems, modem manufacturers, and computer terminal manufacturers as a standard for serial communication. Its full name is “serial binary data exchange interface … Read more

It is often said that an operating system (OS) is one of the three great romances for programmers. We frequently use terms like “soul, brain, kernel, foundation” to describe it, highlighting its significance in the realm of computing. In practical work, this is indeed the case; many of the troubleshooting issues we encounter are closely … Read more
