Abstract: I heard that many friends learning microcontrollers can’t use structs? Pointers and structs are essential to mastering microcontrollers. If your C language skills are shaky, you won’t grasp the essence of microcontrollers and will only complete some basic projects. Understanding structs and being able to use them flexibly indicates that you have entered the … Read more

Word Count:4500 Content Index:⭐⭐⭐⭐⭐ Concept of Linux Device Driver System calls are the interface between the operating system kernel and application programs, while device drivers serve as the interface between the operating system kernel and machine hardware. Device drivers abstract hardware details from application programs, allowing them to interact with hardware devices as if they … 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
Word Count: 6000 Content Quality Index: ⭐⭐⭐⭐⭐ Abstract: Have you ever wondered where the functions and variables you write in Keil for microcontrollers end up? We often talk about the five areas of memory, but what exactly are those five areas? Where are they located on the chip? And why is it that after learning … Read more
GPIO, translated as General Purpose Input Output. I believe everyone is quite clear about the meaning of input and output. The most commonly used output function is the LED, while the most commonly used input function is the key. To use the GPIO functionality of STM32, the first thing to clarify is who controls this … Read more
C language is essential foundational knowledge in microcontroller development. This article lists some common C language basics encountered while learning STM32. 1 Bit Manipulation First, we will explain several bitwise operators, followed by tips for using bitwise operations. The C language supports the following six types of bitwise operations: Next, we will focus on some … Read more
Word Count: 9000 Content Quality: ⭐⭐⭐⭐⭐ 1. Prerequisite Knowledge—Memory Allocation in Programs A program compiled by C/C++ occupies memory divided into the following parts: 1. Stack Area (stack)—automatically allocated and released by the compiler, used for storing function parameters and local variable values. Its operation is similar to a stack in data structures. 2. Heap … Read more
C language, as an ancient and powerful programming language, is the starting point for many programmers learning programming. It not only lays the foundation for learning other high-level languages but also has extensive applications in system programming, embedded development, and other fields. If you have already enrolled in our embedded course, let’s start learning together … Read more
Article Length: 4600 Content Quality Index: ⭐⭐⭐⭐⭐ Memory Operations in C Language Embedded System Programming In embedded system programming, it is often required to read and write content in specific memory units. Assembly language has the corresponding MOV instruction, while other programming languages, except C/C++, generally do not have the capability to directly access absolute … Read more
