How to learn the problem of single-chip microcomputer, these four steps I designed are not a slap in the head, but a very scientific learning method based on many learning experiences and teaching experience. Let me briefly talk about it. Why do you follow four steps to learn.
Is it difficult to learn from a single-chip computer? Is programming difficult?
In 2017, the programming group participating in the MCU programming contest has a minimum age of 14 years, and the primary assembly group has a minimum age of 8 years. The MCU learners asked themselves how old they are, regardless of their ability to learn or understand, I think the students are more than these children. But why can they learn, but we learn to find it difficult?
The problem is that your advantage is your disadvantage.
First, the parrot tongue
A 10-year-old child, when he first started learning Chinese, mathematics, usually learns to memorize, learn multiplication, and practice repeatedly. When I was in elementary school, I started to learn complicated Chinese characters in the third grade. I learned mathematics four mixed operations. One does not know how many times to recite the poems repeatedly. I don't know how many math problems to practice. Especially when learning mathematics, the exam will have a calculation paper, allowing mathematics to check and finally write the answer on the exam paper.
So the first step: parrots learn tongue, in fact, it is reciting. Because the MCU is completely new to you, it is not much different from a 10-year-old child who has a third-grade Chinese language math.
Some people will say that programming is a kind of logical thinking. It is not a nonsense to recite a program. When we recite the ancient poems, we know what it means to "between the white emperor and the clouds". You don't need to know, you only have to carry it. And now you definitely know what it means.
The misunderstanding of many students is that he thinks they can understand and understand, so they are looking at them instead of copying them. I have seen it, I feel that I understand it. I really did it, and the program I wrote was a mess. The purpose of the first step is to let you remember and then understand. You didn't remember, understand a wool. Only you remember, the content stays in the computer, then as you learn later, you will slowly digest and understand.
Second, according to the gourd painting
I have copied it, I have passed it, what is the rest? It is dictation. The so-called dictation is the same as the primary school exam. Is there any use for exam-taking? China’s basic education, if the world is second, no one dares to call the first. Some opponents will say that this is not a fool-like teaching? The process of dictation, every time you write a program, is the process of understanding what the program plays, that is, the process of further familiarization with the microcontroller and programming. This step is more important than the first step. The first step is to copy and recite. The second step is to find out what you don't know by dictation. I feel a little bit around, that is to say, there are many mistakes, you don’t know what you will commit, and you don’t know where the program needs special attention. Only when you do it once, you can know where you don’t understand, write the program. In the end, it is easy to make mistakes. It doesn't matter if the first pass is not successful. Go back and check to find out where it is not remembered, where you don't understand, where it is wrong, and then write it again. This is a process of testing, which is to help you find your own omissions. If you just follow the tutorial and don't do it yourself, you never know where your problem is.
Third, the stone of other mountains can attack jade
In all kinds of tutorials, a lot of program code is the crystallization of our first-line engineers' experience, which is very practical. Therefore, when you are doing homework, you can understand it when you are developing other products.
However, students should pay attention to the fact that the transplant is not equal to ctrl +c and ctrl+v. The transplant should have a thorough understanding of the content. After copying, a seamless connection should be made. When doing a seamless connection, first analyze the interface differences between your own programs and the code in the tutorial, then copy them over and debug them to be easy to use. Students often copy part of our code and say how it works. It is difficult to use debugging, and the debugging program is an indispensable experience for every engineer.
Fourth, the combination of theory and practice, Wenzhi knows new
The classmates who went to the fourth step were basically the better classmates I had studied before. I almost want to review the tutorial again. I think this part of the class is very clear. I often hear from some students that there will be new gains every time. As for practice, as I said before, I have the opportunity to practice and must participate in practice. I have the opportunity to practice and find opportunities to practice. Only soldiers who have experienced actual battles on the battlefield have real combat skills.
