Help! C language almost drove me crazy, but I survived. I was really about to break down! Learning C language is simply torturing myself! Every time I open the IDE (Integrated Development Environment), my hands tremble because I know I will face a bunch of incomprehensible error messages. Those moments that drove me crazy: Pointers? … Read more
01Introduction: In C language for microcontrollers, due to resource limitations, pseudo-random number algorithms are usually employed. 02Common Methods 1. Standard Library Function Method (Requires Hardware Support) Note: Some microcontroller standard libraries may not support the rand() function. #include <stdlib.h> #include <time.h> // Initialize random seed (requires external variable, such as ADC noise) void init_random() { … Read more

In engineering development, it is sometimes necessary to first confirm which part of the code consumes time in order to optimize the program. So, how do we measure code execution time? In previous articles, two methods were mentioned: using an oscilloscope to measure I/O level changes to calculate code execution time, and using the System … Read more
Continuing from the previous article, we have already learned about the porting and startup process of FreeRTOS. Today, we will continue to study the task management part of FreeRTOS, starting with understanding what a task is. 1. Task 1.1 Introduction to Tasks (1) In bare-metal systems, we generally use a front-and-back system for development. If … Read more
