The Design Requirements for a Perfect PLC Program A complete PLC program is not just about making the system operational; it also requires comprehensive comments, excellent architecture, good scalability, a complete alarm protection system, and a simulation system before operation. 1. Simplicity Keep the PLC program as simple as possible. Simplicity means using standardized program … Read more

In the programming world of Python 3.12, class inheritance has long transcended the superficial understanding of “subclass reusing parent class code” and evolved into a deep architecture that embodies software design principles, type system constraints, and code evolution capabilities. This article will reveal five core dimensions of class inheritance in the context of Python 3.12, … Read more

Embedded development, especially in os-less microcontroller programs, often suffers from the rampant use of global variables.This phenomenon is common among programmers transitioning from early assembly language and beginners, who tend to treat global variables almost like function parameters.They define numerous chaotic structures in .h files, declare a bunch of externally visible global variables that are … Read more

Today, I want to share some “unconventional” yet extremely useful tricks in embedded development that seasoned veterans rarely disclose! First Technique: Hardware Issues? Pass the Buck First!If you encounter a program crash, don’t rush to modify the code! First, check if the hardware layout matches the schematic. Our project was delayed last time because a … Read more
Preface:I love embedded systems. The first time a motor turned because I told it, I was hooked. I quickly moved away from pure software and into a field where I can touch the world. Just as I was leaving software, the seminal work was done on design patterns. I love embedded systems. The first time … Read more
Click the above blue text to follow C Language Chinese Community Source: CSDN 1. Principles Low coupling refers to making modules as independent as possible. While it is impossible for modules to have no connections, the interfaces between modules should be minimized and simplified. Thus, high cohesion from the perspective of the internal characteristics of … Read more
