This article discusses the issue of global variables in embedded C programming. In embedded systems, especially in OS-less microcontroller programs, a common mistake is the excessive use of global variables. This phenomenon is often seen among programmers transitioning from early assembly languages and beginners, who tend to use global variables almost like function parameters. They … Read more

File locks are widely used in various applications, such as database systems, … Read more
【Research Highlights】The lithium-oxygen battery, despite its high theoretical energy density (3500Wh/kg), still faces significant challenges for commercial application. One major challenge in charging lithium-oxygen batteries is the low charging current, high overpotential, numerous side reactions, incomplete charging decomposition, and low coulombic efficiency. The discharge product lithium peroxide (Li2O2) is an insulating solid, which complicates the … Read more

Click the above“Mechanical and Electronic Engineering Technology” to follow us In programming, we often encounter scenarios where a function needs to return multiple values. Although C++ functions cannot directly return multiple parameters, we can easily achieve this requirement through some indirect methods. This article will detail several common implementation methods and analyze their advantages, disadvantages, … Read more
Introduction In modern game development, the performance of the game physics engine is crucial for creating a realistic gaming experience. From collision detection to complex rigid body motion simulation, the physics engine needs to handle a large number of mathematical calculations. The traditional Single Instruction Single Data (SISD) processing method gradually reveals performance bottlenecks when … Read more
One of the long-term goals of artificial intelligence is to train a “generalist” model that can simultaneously solve various types of tasks, acting as a versatile general model. Currently, in the field of AI, the most rapid advancements are seen in subfields such as computer vision, natural language processing, and their intersections. One of the … Read more
