Everyone is asking about SCM. Today, xiaobian will share four knowledge points about SCM with you:
1. Introduction to SCM: Take PC as an example, including CPU, memory, and hard disk. You can understand microcontroller is a super small PC, CPU, memory, hard disk are all in this chip (MCU).
2. The use of microcontroller: take PC as an example, you can use C++, C#, JAVA and other programming on THE PC, microcontroller can also be programmed, but it uses C to complete some control functions, such as ordinary electronic toys, there will be microcontroller to achieve control.
3. How to learn microcontroller: microcontroller learning has several points, such as microcontroller principle, circuit diagram, C language programming, interface application, peripheral device driver, etc.; Many beginners will ask: Which one should I learn first? Personally, don't read dead or stupid books.
Microcontroller is a kind of operable thing. It's best to invest a little, buy a development board, and learn as you go. The most interesting personal feeling is probably the C language, and from the development board routines, we can start tweaking the code, doing little experiments, seeing what the development board looks like, and then understanding each principle.
4 microcontroller how to enter: this problem is often novice can not locate their own point. The concept of entry is really hard to define. Know what register is, how to control IO, how to drive the peripheral IC, so even the entry.
