The C language is essential foundational knowledge in microcontroller development. This article lists some common basic knowledge of C language in STM32 learning. 01 Bit Manipulation Bit manipulation is different from bit-banding operations. Bit manipulation refers to performing operations on each bit of a variable, while logical bit operations are performed on the variable as … Read more
The C language is essential knowledge in embedded learning, and most operations revolve around C language. Among them, there are three “hard nuts to crack” that are almost universally recognized. 1. Pointers Pointers are recognized as the most difficult concept to understand, and they are a direct reason many beginners choose to give up. The … Read more
The structure of local chronicles refers to the composition method of various components of the chronicles, that is, the arrangement method of the chronicles. The function of the structure of local chronicles is to arrange various contents in certain positions, making the whole book an organic whole with an orderly arrangement and reasonable layout. The … Read more
When it comes to pointers, it is impossible to separate them from memory. People who learn pointers can be divided into two types: those who do not understand the memory model and those who do. Those who do not understand typically think of pointers as “pointers are the address of a variable” and are quite … Read more
Click the blue text above to subscribe with one click. Generally, the high sensitivity and wide detection range of pressure sensors cannot be achieved simultaneously. For example, introducing layered microstructures on the surface of flexible materials can effectively enhance the sensitivity of pressure sensors, but due to the limited compressibility of microstructures, high sensitivity can … Read more
1. A pipeline achieves maximum efficiency only when it is filled with instructions, meaning that one instruction is executed per clock cycle (this refers only to single-cycle instructions).If a jump occurs in the program, the pipeline will be cleared, and it will take several clock cycles to refill the pipeline. Therefore, minimizing the use of … Read more
C Language Structures (struct) From Beginner to Advanced 1) What is a Structure? A structure (<span>struct</span>) “packages” different types of logically related data into a whole, making it easier to pass, store, and manage together. Unlike arrays that can only hold “elements of the same type”, structures can hold “members of different types”. 2) Definition, … Read more
The Concept of Pointers A pointer is a special variable that stores a value interpreted as an address in memory. To understand a pointer, one must grasp four aspects: the type of the pointer, the type it points to, the value of the pointer (or the memory area it points to), and the memory area … Read more
Scan to follow Chip Dynamics and say goodbye to “chip” congestion! Search WeChatChip Dynamics Today we are going to talk about a super practical “data management tool”—the structure (Struct)! Perhaps you have experienced this frustration while coding, with variables scattered everywhere: int age; char name[20]; float score; it feels like rummaging through a drawer for … Read more
C language is an essential knowledge in embedded learning, and most operations revolve around C language. Among them, there are three “hard bones” that are almost universally recognized as difficult to tackle. 01 Pointers Pointers are recognized as the most difficult concept to understand, and they are a direct reason many beginners choose to give … Read more
