What is a framework? A program framework is similar to a file outline or template. Writing a program is like writing an article; without an outline or template, it can be quite cumbersome. Why Have a Framework? To save time and reduce errors. For a specific type of program, the logical structure of the code … Read more
*Example 1: Use P3 port to light up 8 LEDs in sequence #include<reg51.h> // Include microcontroller register header file / Function: Delay for a certain period of time void delay(void) { unsigned char i,j; for(i=0;i<250;i++) for(j=0;j<250;j++) ; } / Function: Main function void main(void) { while(1) { P3=0xfe; // First light on delay(); // Call … Read more

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

1. What are the advantages and disadvantages of using C language and assembly language in microcontroller development? Answer: Assembly language is a symbolic language that uses mnemonic symbols to represent machine instructions, making it the closest language to machine code. Its main advantages are low resource usage and high program execution efficiency. However, assembly languages … Read more
Using “Software Traps + Program IDs” to Handle PC Pointer Jumps When the CPU is disturbed by external factors, sometimes the PC pointer can jump to another part of the program or to a blank segment. In fact, if the PC pointer jumps to a blank segment, it is relatively easy to handle. Just set … Read more
