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
Word Count: 5600 Practical Index: ⭐⭐⭐⭐⭐ Considerations for C Programming in Embedded Systems – Screen Operations The problem to be solved now is that often in embedded systems, a complete Chinese character library is not used; instead, it is often necessary to provide a limited number of Chinese characters for essential display functions. Chinese Character … Read more
Hello everyone, today I am sharing an article about a microcontroller program framework. 1. Importance of Program Framework Many people, especially beginners, often write code without an overall plan, leading to increasingly messy code and constant bugs. Eventually, the code seems to run fine (it might actually be fine), but when adding a feature, a … Read more
1. The pipeline can only achieve maximum efficiency when filled with instructions, that is, completing the execution of one instruction per clock cycle (only referring to single-cycle instructions).If a jump occurs in the program, the pipeline will be cleared, which will take several clocks to refill. Therefore, minimizing the use of jump instructions can improve … Read more
Word Count: 1700 Content Quality Index: ⭐⭐⭐⭐⭐ 1 Point of View 1 Just like learning English, the C language is also a language. C is quite simple, with only 34 keywords (ANSI standard, but C99 introduces several new keywords and features to define new data types, variable-length arrays, etc.), over 40 operators, and an understanding … Read more
This article is selected from the Extreme Technology Community column “Bare Metal Thinking”. The article mainly shares free tools related to “performance/time” for super embedded systems open-sourced on GitHub. Is it really free from the start? For the well-known Cortex-M processors, whether it is the Cortex-M0 emphasizing extreme resources and low power consumption or the … Read more
Word Count: 18000 Content Index: ⭐⭐⭐⭐⭐ The Concept of Embedded Systems: Focus on Understanding the Concept of “Embedded” 1. From a hardware perspective, integrating CPU-based peripheral devices into the CPU chip itself. For example, early computers based on the X86 architecture only had arithmetic and accumulator functions. All chips needed to create external bridges for … Read more
