The confusion I encountered when learning stm32

The year is almost over , Take the last free time to talk about what I used to study STM32 Some puzzles encountered in the process of , Experience gained by solving puzzles 、 Share your experience . I hope to provide some help to some friends who want to learn SCM .

Study STM32 The most important point is that we should make it clear that we learn SMT32 What functions should be realized through it , That is, you need to determine a development project .

If you don't have a goal , Then make a minimum system ; Since we want to establish this project , Then we need to know what components are needed for the smallest system . Minimum system by STM32、 Simulation part 、 There are also control parts . The simulation part includes 、 Analog to digital converter 、 sensor ; The control part includes motor 、 Relays, etc . First understand these things .

The first problem I encountered when I was studying was how I should study . Follow books or watch videos . I think this place is the first place where I stepped on the pit , This is also personal .

I chose to study by reading , Most people who read textbooks have a feeling , Book knowledge is the authority. We should watch it very carefully , Don't miss every knowledge point , With a high degree of concentration and no one to explain, it is easy to get sleepy . That's why I realize that video learning is more suitable for me . Because the video is explained by learned practitioners , They will pick the point and say , Let us know what is the key to learn , It is convenient for us to study .

The second problem is to choose the development method . Just beginning to learn SMT32 We should choose to develop by register 、 Is it developed in the form of standard library or through HAL In the form of Library . I chose the standard library to develop , Because the video I watch is developed with this . At that time, there were more standard libraries written on the forum, and it was easier to find such materials .

For beginners HAL Development is not very suitable , After all, knowledge is still in the reserve stage , Many development principles 、 The workflow may be relatively unfamiliar to beginners ,HAL Library is convenient , But it can't help us understand the internal structure of MCU 、 Build our development thinking , It will let us miss a lot of valuable experience .

Register development requires us to spend a lot of time to be familiar with the function of registers , Which part does it control correspondingly ,32 The register of belongs to the more one , So I don't recommend you to use this method .

Some friends might say HAL Better than standard library , It's true . Let's take a simple example , The standard library is equivalent to a car with manual transmission ,HAL Equivalent to an automatic car , Friends who have driven cars know that cars with automatic transmission are usually easy to drive , But if we learn automatic gear at the beginning instead of manual gear , If you have to drive a car with manual transmission, you may not be able to drive . This is the simplest truth .

Finally, let's talk about my little advice for beginners , It is impossible to learn SCM at once , All knowledge is unlikely to be learned at once . We should learn while doing , If you have any idea, go to the MCU to practice immediately , Never do it after reading or learning , This is not applicable to single chip computers . SCM is more hands-on ability , Learning and doing more is the best way to understand SCM .
