How can I learn microcontrollers well?

Let's talk about the single-chip microcomputer first. Generally, the MCS-51 single-chip microcomputer that we use more now has a lot of information, many people use it, and the market is also very large. In my personal experience, how can I learn the single-chip microcomputer course faster? The single-chip microcomputer course is a subject that attaches great importance to hands-on practice. You can't always read books, but you must read books first to learn it, because from the book you need to have a general understanding of the various functional registers of the single-chip microcomputer. To put it more clearly, we use the single-chip microcomputer to control the various functional registers of the single-chip microcomputer with software. To put it more clearly, it is to control when the level of those pins of the single-chip microcomputer outputs high and when it outputs low. These changes in high and low levels control your system board and realize the various functions we need. As for reading books, you only need to have a general understanding of what the pins of the single-chip microcomputer do? What kind of functions can be realized? You may not understand it the first time or the second time, but it doesn't matter, because you still lack practical sensory understanding. So I always say that it is enough to read books for two or three days to learn single-chip microcomputers. You can read five or six novels a day, and it is enough to read single-chip microcomputers two or three times in two or three days. You don't need to read them carefully. I recommend a book. This one is enough. The title is "New MCS-51 Single-chip Microcomputer Application Design", which is published by Harbin Institute of Technology Press and the author is Zhang Yigang. It is very important to have a general understanding of the content of the book and then practice. If you don't practice to learn single-chip microcomputers, it is impossible to learn. There are two ways to practice. One way is to spend money to buy a single-chip microcomputer learning board. It doesn't require too many functions. For beginners, you buy a board with many functions. There are many things on it that you will never use in your life. I suggest running lights, digital tubes, independent keyboards, matrix keyboards, AD or DA (the principle is the same), LCDs, buzzers, and that's about it. If you can skillfully apply the things I mentioned above, it can be said that you have already got started with the hardware of single-chip microcomputers. The rest is to practice designing circuits by yourself and constantly accumulate experience. As long as you pass the first level, the rest of the road will be much easier. Everyone may have heard that everything is difficult at the beginning. Method 2: If you have an expert in single-chip microcomputers around you, ask him for help and let him help you build a simple minimum system board. For an expert, it only takes one minute to make a minimum system board for a single-chip microcomputer, but it is much more difficult for a beginner, because only when you understand the hardware can you use it skillfully. If you don’t have such an expert around you and can’t find someone who can help you, then I advise you to buy one yourself. After all, it is much more convenient to have one yourself. You can use it when doing small experiments such as single-chip microcomputers in the future, and it is also trouble-free.  

After you have a MCU learning board, you should practice more. It is best to have a computer. Watch fewer movies and play fewer games every day. Connect the learning board and the computer, open the debugging software and sit in front of the computer. First learn how to use the debugging software, and then start with the simplest running light experiment. When you can make the eight running lights flow freely according to your wishes, you have already entered the door. You will find how fascinating the MCU is. It is so fun. This is not learning knowledge, but playing. When the program you wrote is realized according to your wishes, you are happier than doing anything else. You will be addicted, really. People who do electronics are really addicted. Then make the digital tube light up. After these two items, you can't extricate yourself. You have begun to consider which line of work you will go in this life. This is how to practice. When writing a program, you will definitely encounter many problems. At this time, you will look for it in a book or ask others. When you get the answer, you will remember it for a lifetime. Knowledge must be used in real life to solve practical problems, so that it can play its role. Think about it yourself. You have been in college for so many years and have classes every day. What have you learned in class? Are you busy for the final exam? You got 90 points after the exam, so happy, hahaha, but you forgot everything when you came back from the next semester, right? What did you learn? But I tell you that once you learn the microcontroller, you will never forget it. In addition, let me talk about the problem of programming in assembly language and C language. Many students have C language courses in their freshman and sophomore years. I have also taken them. I know that at that time, every day I was multiplying, adding, and calculating factorials. What's the use of learning it? Would you be stupid if you were asked to program the microcontroller in C language? We must be able to use what is in the book. Microcontroller programming can be done in C language or assembly language, but I suggest that it is better to use C language. If you have a foundation in C language, it will be easier to learn. If not, you can also learn C language while learning microcontrollers. C language is also very simple, just a tool. I advise you to learn it as it will definitely be useful in the future. Otherwise, you will have to learn it in the future. It doesn't matter if you don't know any assembly language, but if you don't know any C language, you will suffer in the future. Writing program code in assembly language is highly efficient, but relatively difficult and wordy, especially when encountering algorithmic problems, it is extremely troublesome. Now the main frequency of microcontrollers is constantly increasing, and we do not need such high-efficiency code at all, because there is a high-frequency clock, and the ROM of microcontrollers is also constantly improving, which is enough to hold any code you write in C language. C language materials are abundant and easy to find, and it will be very portable in the future. You only need to change an IO port to write a temperature sensor program and it can be used anywhere, so I advise everyone to use C language. 

In summary, as long as you have confidence, can stick to things, and have a strong will not to give up until you succeed, then learning a microcontroller is a very easy thing.
