Wu Jianying Microcontroller Development Board Address Store:【Wu Jianying’s Shop】 Address:【https://item.taobao.com/item.htm?_u=ukgdp5a7629&id=524088004171】 The compiler uses two stacks: one is the hardware stack for subroutine calls and interrupt operations, and the other is the software stack for temporary variables and local variables passed in a stack structure. The hardware stack is allocated starting from the top of the … Read more
The learning and application of microcontrollers is rapidly rising in factories, schools, and enterprises. Engineers and technicians who are accustomed to traditional electronics face new challenges. If they cannot learn microcontrollers in a short time, they will inevitably be left behind by the times. Only by bravely facing reality, challenging oneself, enhancing learning, and striving … Read more

First, let’s pose a question: what do you think the output of the following code will be? /* A simple example code */ #include <stdio.h> int main(int argc, char const *argv[]) { int a = -10; int b = 10; int c = -3; int d = 3; printf("Result 1: %d\n", a%d); printf("Result 2: %d\n", … Read more
In the world of C programming, code safety and resource management have always been crucial topics. Today, we will focus on a feature that is expected to become an important part of future versions of C language: ‘defer’. We will explore how to apply this feature in existing tools and compilers, as well as its … Read more
Today, let’s talk about the C language. When I first started learning, I was also confused, thinking it seemed simple, but I encountered various problems when using it. After years of trial and error, I would like to share some of my insights with you. Here are examples of using selection statements in C language: … Read more
If you find this useful, pleaselike and share it; your encouragement is my motivation to create! 1. C Language Programming Exercise Description We have 10 integers, and we need to shift each integer to the right by one position, with the last integer moving to the first position. For example, the integer sequence: 1,2,3,4,5,6,7,8,9,10 After … Read more
