For new students, if you have no contact with single-chip microcomputer, it is recommended to get started with 51 single-chip microcomputer

For new students , If you have no contact with SCM , I suggest 51 MCU starts getting started , This is because ,51 SCM in SCM , You could even say , It is the simplest single chip computer , It is very suitable for getting started , Back up , You can learn STM32.

STM32 It began to be complicated , The reason is powerful , You need to configure more programs , such as 51  You need to control a single chip computer IO It only needs 2 A statement ,STM32 about IO mouth , There are many modes and rates for you to choose , You even need to turn on the peripheral clock , This is in 51  There is no single chip microcomputer , But you already have 51  The basis of , These can be further studied , Especially students with good hardware foundation , It went well .

The article is relatively long , More words , You can first open the avatar and pay attention to me , Then take your time ,/// Insert a ： At the beginning of this year, I recorded a set of systematic introductory single chip microcomputer tutorial , If you want, just ask me for it. It's free , I can send a private message ~ Click the black font in the lower left corner of my avatar and I can also get it . I've been relatively idle recently , Take me to finish the design , Take students to provincial or above competitions ///

For library function and register development , I suggest getting started , For simple peripherals , such as IO mouth , A serial port , You can use registers , Because the process of register configuration , It can let you know the register of SCM , Learn to read the data manual , After you configure several peripherals with registers , You can use library functions , such , You can also experience why library functions appear , And better understand what library functions are .

Last , You said firmware library ,HAL, register , It should mean STM32, First Firmware library yes ST Earlier library functions , At present, some new microcontrollers do not have this library , Replaced by , yes LL library ,HAL It's the ratio LL Library to a higher level , It may be a little difficult to understand , Simply speaking , before   The firmware library is old , and LL and HAL Library is a new library .LL library and HAL The library is biased towards the bottom , Efficient , One is the application layer , Compatibility is good. （STM32 But a big family , There are all kinds of single chip computers ）

The cost of single chip microcomputer is low , finger 51 series , Don't say arm, High stability , It is extremely suitable for low-cost automated development . Traffic lights on the road ,led Dot matrix billboard , All use , Not to mention slightly high-end applications . Single chip microcomputer is good , Future work is guaranteed .

For MCU , The future development can be summarized as , Lower power consumption , Smaller volume , Mainstream single chip microcomputer coexists with many varieties .

In order to better adapt to new needs , Whether it's industrial control or living needs , SCM industry will certainly continue to develop more powerful SCM , Function more , Better performance , However, the basis of single chip microcomputer is interlinked .

Enter the opposite door , Adjust state of mind . SCM is like a chisel or hammer , You can use it when you get it . A layman or a child may use it before long , But if you want him to carve a high-level sculpture in a short time, you need experience and patience . Have high demands on yourself , Don't rush to get results , This is the mentality that we should have when we develop single chip microcomputer projects .

This industry is a constant learning , A spiraling industry , You need to keep a learning attitude , Only by constantly injecting new knowledge and experience can we keep up with the times , This is the best way to adapt to the future trend of SCM industry .

Friends interested in MCU can come to me , I recorded some introductory tutorials about MCU , If you need children's shoes, just ask me for them , Free of charge , Private confidence in me “ Miss Lin ” You can take ～ Click to open my avatar to receive
