A thread is the smallest unit of execution in a program, representing an independent execution path within a process. A process can contain multiple threads that share the process’s memory space (such … Read more
C programming is a widely used and popular programming language, rich in operators and data types, making it easy to implement complex data structure calculations. It combines the features of high-level languages with the ability to program directly at the hardware level, suitable for various operating systems, and programs written in C are fast, efficient, … Read more
The 99 multiplication table is a classic case for practicing loop structures, easily implemented through nested loops. Structure Analysis of the 99 Multiplication Table Row 1: 1×1=1 Row 2: 1×2=2 2×2=4 Row 3: 1×3=3 2×3=6 3×3=9 … Row 9: 1×9=9 … 9×9=81 Pattern: The i-th row contains i expressions, each expression is<span>j×i=result</span> (where j ranges … Read more
I am Lao Wen, an embedded engineer who loves learning.Follow me to become even better together! When writing code, we assign an initial value to variables to preventcompiler issues that may lead to uncertain initial values for variables. For numeric type variables, they are often initialized to 0, but how should other types of variables, … Read more
The flexible SINUMERIK can realize many of your ideas. If you want to usePLCto read the current processing program segment, no problem, let’s arrange it!First, you need to find the variable. It is recommended to search in the book “SINUMERIK ONE / NC variables and PI services” (List Manual). I searched for the keyword “current … Read more
Embedded systems are a core component of modern technology, widely used in smart homes, industrial control, automotive electronics, medical devices, and more. For beginners, mastering embedded development requires a systematic learning path. 1. Basic Preparation Stage (1-2 months) Fundamentals of Electronic Circuits Master basic circuit components: resistors, capacitors, inductors, diodes, transistors, etc. Understand the basics … Read more
A <span>struct</span> is a user-defined data type in C language used to combine different types of data into a single unit, commonly used to organize complex data structures. In embedded systems and microcontroller development, structs are widely used for data packaging, module management, and communication protocol encapsulation. 1. Definition of Structs The basic definition format … Read more
The C_SysInfo project can actually be seen as a simple translation of the previous PySinfo project. This is a typical scenario where I believe online models and local models are particularly suitable for application – a broad “translation” process: 1.The requirements must be very clear about what needs to be done, and the technical path … Read more
If you don’t want to miss my updates, remember to click the top right corner – view public account –set as a star, and I’ll send you a little star. The C language can be considered an “ancient” programming language, yet it remains a mainstream programming language in embedded systems today. Without C, there would … Read more
The concept and usage of pointers in C language play a crucial role throughout the learning process. Pointers can simplify certain C programming tasks, and some tasks, such as dynamic memory allocation, cannot be performed without pointers. Therefore, learning pointers is essential to becoming an excellent C programmer.As we mentioned, every variable has a memory … Read more
