Hello, my undergraduate major is electronic information engineering, and I am interested in electronic development. I have also read many books on electronic development. I graduated from graduate school this year and worked on hardware-related projects for three years, all of which were related to single chip microcomputer. In fact, what I want to say is that most students can't apply what they have learned from books to practice during their undergraduate years. For example, no matter how good your test scores are in circuits, digital signals and communication principles, it doesn't mean that your design ability is strong. When I graduated from college, I designed a single chip microcomputer, only to find that I really didn't fully understand what was in the book. I was at a loss at first.

In fact, there is no need to be so entangled in choosing books, such as the principle and application of single chip microcomputer, the programming of C805 1, and the programming of C language application of single chip microcomputer, as long as it is related to C. In fact, C (C5 1) in single chip microcomputer is much easier than books in C language, but the important thing is that you are different from reading books and developing hardware. You can go to Taobao if you have the conditions. Cheap 40, 50 yuan, much better than reading a book casually. Moreover, learning MCU needs a foundation of analog and digital electricity. For example, the basic peripheral circuits, transistor amplification circuits, digital tubes and liquid crystal drive circuits of MCU all belong to the category of analog electricity, while trigger circuits and sequential logic circuits belong to the category of digital electricity. So you should find at least three books to read together, mainly single chip microcomputer. If there are difficulties, look at analog and digital electricity. In fact, what I said is relatively basic. I hope you will.
