When it comes to embedded programming, many people’s first impression is C/C++. However, you will find that microcontroller development is mostly done in C, with very few using C++. So, can C++ be used for microcontroller development? The answer is definitely yes. Below, based on Keil and STM32, I will describe how to use C++ … Read more
Are you still using the most basic<span>#define PI 3.14</span>?80% of embedded engineers have not truly harnessed the power of macros! When you see meaningless entries in your debug logs like<span>val=123</span>, when your code is filled with repetitive type conversions, and when you want to implement generic operations but feel helpless—today, these two symbols willrevolutionize your … Read more

01Introduction: Let’s start with the correct code. We will use a six-byte array for testing: [0x0a, 0x03, 0x02, 0x00, 0x00, 0x16]. 02Function and Results 1. Function // Example with 0a 03 02 00 00 16 var buffer = [0x0a, 0x03, 0x02, 0x00, 0x00,0x16]; // Call the function to calculate the CRC checksum var crc = … Read more
Today, embedded systems are increasingly applied in various fields such as smart homes, smart healthcare, industrial automation, and intelligent transportation. In the development of embedded systems, data structures are an essential knowledge point. This article will introduce several common data structures in embedded programming, including arrays, stacks, queues, heaps, hash tables, and linked lists. 1. … Read more

Today, I will explain pointers. From basic to advanced, this article will combine practical applications to help you learn pointers while understanding what experts use pointers for!Long article warning! The entire text is about 5200 words, and this article is enough to learn pointers!Many people, like me when I first learned C language, are afraid … Read more
MicroPython is one of the most popular topics in open-source hardware in recent years, invented by Professor Damien George from the University of Cambridge, and is essentially a version of the Python language used for embedded programming.One of the challenges in embedded programming is that programmers need to focus not only on the software but … Read more
The demands of embedded development programming are ever-changing. To achieve system stability and code reusability, high cohesion and low coupling must be maintained.It is generally believed that time-consuming operations cannot be executed within interrupts, as this would affect system stability. For programs with an operating system, interrupt handling can be divided into two parts through … Read more
How to Build Embedded Programs and Find Documentation 1.
