What basic knowledge is needed to learn microcontrollers
2024年07月23日 10:22
The basic knowledge of circuits includes the basic concepts and laws of circuits, equivalent transformations of circuits, linear circuits, sinusoidal AC circuits, mutual inductance circuits and ideal transformers, non sinusoidal periodic signal circuits, transient circuits, and general analysis methods and basic theorems; Circuit Principles is a compulsory course in the field of electronic information, which mainly focuses on analyzing electromagnetic phenomena in circuits, studying the basic laws of circuits, and analyzing methods of circuits.
In C language, the called function cannot directly modify the variables in the calling function, but only modifies its private temporary copy; You must provide a variable (pointer) to be set as the called function, which needs to declare the corresponding parameters as pointer types and can indirectly access the variable; I personally prefer C language development. Compared to assembly, its advantage is better portability. Learning 51 microcontroller and C language programming certainly requires some foundation.
Microcontrollers, also known as single-chip microcontrollers, are not chips that perform certain logical functions, but rather integrate computer systems into a single chip; Microcontrollers also have the characteristics of small size, low price, powerful functions, fast speed, wide application range, strong flexibility, and high reliability; The requirement for hands-on skills such as welding is not so strict, but it is still good to be able to build beautiful circuits.
