This series will explain the book “Assembly Language”. This section covers Chapter 5 – **[BX] Register and Loop Instructions**. In this section, we introduce another way to describe memory, the [BX] register, and the commonly used loop instruction: loop, discussing its applications, significance, and related content. The entire text uses (ax) to represent the contents … Read more

Today we are going to talk about that love-hate character in C language — pointers! Some say that pointers are the soul of C language; if you haven’t learned pointers, you haven’t learned C. Others say … Read more

In embedded development, pointers are the “core engine” for directly manipulating hardware and optimizing memory usage. From register operations to data transmission, the flexible use of pointers allows for more efficient code that is closer to the essence of hardware. 1. Basics of Pointers: The “Connection Link” Between Addresses and Variables 1. A pointer is … Read more
Recently, I came across a very interesting term “callback hell”, which refers to the endless nesting of callback functions that ultimately leads to stack overflow and deadlock. The manifestation of this is multiple layers of nested function pointer callbacks, resulting in poor code readability and maintenance difficulties.Below is a simple example simulating asynchronous file reading … Read more
In data structures, linked lists are a very important linear data structure. Unlike arrays, linked lists do not require a predefined size and can dynamically increase or decrease in elements. In this article, we will detail how to create and operate on singly linked lists in C. What is a Singly Linked List? A singly … Read more
In C programming, memory management is a crucial topic. Programmers need to use the heap and stack appropriately to optimize memory allocation, thereby improving program performance and stability. This article will detail these two memory allocation methods and provide code examples to help readers understand how to optimize in practical programming. 1. Stack 1.1 What … Read more

Your teacher says, “Pointers are the soul of C language,” but when you stare at the line of code int* p = &a;, it feels like reading a foreign language—what … Read more
Recently, I used FreeRTOS in a project and became curious about idle tasks and hook functions, so I wanted to understand what these two are used for. Here, I will share some of my insights.1. Idle TaskThe idle task is a task that is created by default after the FreeRTOS system starts, and it has … Read more
