The C language is a general-purpose computer programming language that is widely used. The design goals of C are to provide a programming language that can be easily compiled, handle low-level memory, generate a small amount of machine code, and run without any runtime environment support. Despite providing many low-level processing capabilities, C language maintains … Read more
C programs are frequently asked questions in interviews. These programs can range from basics, arrays, strings, pointers, linked lists, file handling, etc. Let’s take a look at the list of C programs. 1) Fibonacci Sequence Without Recursion: #include <stdio.h> void printFibonacci(int n) { int a = 0, b = 1, nextTerm; for (int i = … Read more

The buzzer is a common device, which can be divided into passive and active types. Choose different types of buzzers based on project requirements. In a recent project, we used an active buzzer. As usual, we first designed the circuit board and then proceeded to programming. The schematic in the project is as follows: If … Read more
For embedded systems, if there is no RTOS running, the main function main() in program development needs to use some mechanism to keep running happily forever, it has no endpoint. If you want to exit from the main function, what happens specifically is determined by the C language compiler used. 1. Introduction to the Problem … Read more
In microcontroller programming, many engineers need to operate on registers, among which the reset operation is particularly common. According to the reset method, resetting can be divided into writing 1 for reset and writing 0 for reset. So, is there a difference? Can they be used interchangeably? 1. Operation Method Writing 1 for reset: In … Read more
The AT89C51 is one of the most widely used 8051 microcontrollers, and importantly, it has the feature of being reprogrammable (FLASH). Generally, it can be rewritten 1000 times, providing a low-cost platform for beginners to experiment. To meet the hands-on needs of microcontroller enthusiasts, I spent half a month designing and successfully creating a simple … Read more
