Keep these four requirements in mind when learning single chip microcomputer with zero foundation and avoid detours

Zero basic learning MCU remember these four requirements , Little detours

　　 One of them , Others can be understood by analogy , Get started quickly . If you have none of these conditions , Then follow me , I suggest you study 51 Single chip microcomputer .

　　 Why study 51 Single chip microcomputer ：

　　 Although there are many kinds and models of single chip computers at this time , Each model has a certain market share , But there's no early model  51 SCM that scenery and hot , Although the status is not so high at this time , But because of  51 There are a lot of data accumulated by single-chip computers , You will have a lot of reference materials when you learn , So it must be faster to get started than other models . If you study a slightly eccentric MCU , Maybe a simple software problem will bother you for a long time , Not only waste your study time , More importantly, it has hit the self-confidence of learning SCM .

　　 So is not every single-chip we have to learn it again ? The answer, of course, is No . Everyone follow me to study  51 Single chip microcomputer , You have to learn to draw inferences from one instance and master all skills . There are so many SCM models , After learning one by one, I can't finish learning when my hair is gray , So you follow me  51 Single chip microcomputer , It can't just be  51 Come to study , It's more important to be “ Single chip microcomputer ” To learn , To pass our tutorial , All the internal resources of MCU are clear and clear , Thoroughly understand the usage of each internal module , In this way, when you encounter a single-chip microcomputer that has never been used , You know how to use it for development .

　　 How to learn SCM ：

　　 I mentioned before , SCM is a practical technology , We don't study it for exams anymore , I have summed up for you that the learning method of single chip microcomputer is ： One key point , Four steps .

　　 The key to learning SCM is ： Grow up in practice .

　　 But why do so many people learn SCM , Always holding only one book to read . First of all , Our primary school, middle school and even university learning mode is the same , What to learn mainly depends on reading , Take a written exam ; second , Many people want to practice, but they don't know how to practice .

　　 In case of problems, the effect of checking books is better than that of reading books directly . It's not that people are not allowed to read , But after a little bit of watching , It's time to practice , Then go back to the results of joint practice , Understand the contents of the book . From this place , We have to come to a conclusion , Is learning to be practical

In the process of international technology , It's different from dealing with exams , You don't have to memorize the contents of the book , Books are for checking , It's not for memorizing .

　　 Here are the four steps to learn SCM .

1) repeat the words of others like a parrot

　　 When we first came into contact with SCM , Belongs to the single chip microcomputer industry newborn . What a single chip looks like , The peripheral devices of single chip microcomputer , The internal structure of single chip microcomputer , Use of single chip microcomputer C Language programming methods , Beginners may not have seen , There's no concept in my head . No problem , It doesn't matter if you don't understand some concepts and methods , You don't even need to understand , You just need to follow me to learn like a parrot . For programs , You can copy it down completely , Even copied it two or three times , After a while, you'll find that , You also know a lot of things , Many concepts are slowly understood , You can probably understand others' small programs , Don't think you can see it , And simply copy and paste .

2) Draw a gourd and a gourd

　　 Many students like to watch videos made by others when they study , Look at other people's programs , You can understand , I think I'll be able to , When you write your own program , I don't know where to start , This is easy for beginners to make “ have grandiose aims but puny abilities ” What's wrong with .

　　 Every student , After learning the content of the current lesson , Then turn off the video tutorial , Turn off the source code , By looking at the circuit diagram and looking for any other information that is not source code , Write out the original program code of the current class again , I understand a little bit as I write , It's not just recitation , It should be said that it is a combination of recitation and understanding . Even after a few lessons , You can go back to the previous courses that have been implemented in this way , Do it again in this way . Don't think this step is unnecessary , This step is a key to whether you can really learn SCM , Before you finish this tutorial , Do this for every lesson , If you can complete every program perfectly , So to say , The content of this lesson , Seventy or eighty percent of you have mastered .

3) His shan zhishi , Can offend jade

　　 The biggest characteristic of SCM technology is that different functions can be realized by modifying the program , So the ability to draw inferences from one instance is essential . After the routine of each lesson , You'd better arrange some homework by yourself , In the process of finishing this assignment , Can refer to the original program ideas , On this basis, use your brain to build your own program framework , Finally, the program is completed .

　　 When our engineers develop actual products , This is true in many cases . Like a product , If we start from scratch , There may be many detours , Encounter a lot of setbacks that our predecessors have encountered , So our usual practice is to look for a few similar products , Then study their advantages and disadvantages first , Learn from their strengths , Then we design our own products on the basis of similar products , This is it. “ His shan zhishi , Can offend jade ”.

　　 When beginners are learning , There are a lot of problems , You should think , What's wrong with you , Maybe the predecessors have met , So when you have a problem , Don't panic , First use Google or Baidu search engines on the Internet . Whether it's programming or hardware design , Refer to other people's things , Just analyze other people's things , I used it myself , It will become your own knowledge .

4) The combination of theory and practice , View of

　　 When you have completed all the courses according to the first three steps , It's time to open the book again , Look at the book again , After my own actual combat experience , There will be a sense of sudden enlightenment to many knowledge points . Even video tutorials 、 Books can be read over and over again , There may be some knowledge points that I didn't understand when I was studying , After a while , When you look back and learn again , I'll see in a moment .
