First, let’s demonstrate the effect.The host computer and the embedded system are decoupled through serial communication, meaning changes in the implementations of the host and embedded systems do not affect the interface programming.There is a term in object-oriented design called: “programming to an interface.” This suggests that programming based on class interfaces is less pure … Read more
In actual development, inheritance is a double-edged sword. When used well, it enhances code reusability; when used poorly, it becomes a maintenance nightmare. 1. The Essence of Inheritance: When Should Inheritance Be Used? Many developers have misconceptions about inheritance, believing it to be a universal key for code reuse. In fact, inheritance should serve two … Read more
4 Introduction Python is a high-level scripting language that combines interpretive, compiled, interactive, and object-oriented features. Python’s design emphasizes strong readability, often using English keywords and a unique syntax structure compared to other languages. β An interpreted language: This means there is no compilation step during development, similar to PHP and Perl. β‘ An interactive … Read more
In microcontroller programming, many people can complicate issues that seem simple, creating a mess akin to a spider web in a forest. In fact, according to the philosophy of programming magic, strictly dividing the process of program handling into departments, each performing its own duties, and ensuring that departments do not interfere with each other’s … Read more
Q What is thought? It is the result or the system of viewpoints and concepts formed by the reflection of objective existence in human consciousness through cognitive activities. There are good and bad thoughts; correct thoughts can quickly achieve goals. PLC Programming Design Methods In short: Program = Data + Algorithm A good program structure … Read more
Why should M and T be avoided in PLC programs? The core logic of programming standardization. 1. Fundamental Flaws of Global Variables In PLC programming, global variables such as M (memory relay) and T (timer) are widely used but have inherent weaknesses: unclear ownership and a scope that covers the entire program. The M and … Read more
C++ Computer Syntax C++ is a high-level programming language widely used in computer programming, and its syntax covers various aspects from basic elements to complex programming structures.

Abstract The relationships between devices are various forms of derived inheritance, tracing back to a common origin. This article discusses the concept of “device framework” or “device tree” in embedded systems, analyzing its design intent, core design philosophy, implementation principles, etc., using the device framework of the RT-Thread system as an example. Concept of Device … Read more
