In previous years, when the demand for the Internet was still relatively strong, I believe that we have heard of a certain training in North University of Youth, specializing in software technology training, that will do software is indeed more popular, but this year, with the popularity of the Internet of things and the corresponding application level development, hardware engineer salary treatment began to take a back seat. At present, small to intelligent household appliances, let's say the CNC refrigerator, with fuzzy logic thinking function of the rice cooker, inverter type air conditioning, automatic washing machine, like Xiaomi's Xiao Ai classmates, ofo shared bicycle are involved in the application of microcontroller; large to the car aircraft rocket, Tesla, Xiaopeng car and so on overwhelming are the application of microcontroller products.

Microcontroller profound, precisely because of this to be determined according to the actual situation, remember that we learn the purpose of the microcontroller is product development, the product peripherals run up, and know how to modify it, experience is slowly accumulated, do not be too hasty! If you follow the examples are not used, it is likely that you have not learned the 51 microcontroller, the internal structure and features and properties of functional components you are ignorant, I advise you not to waste time! Or spend your time learning 51 microcontroller, continue to pay attention to my article, I will summarize a basic experience of learning stm32 microcontroller, to help you quickly get started stm32 microcontroller, reduce unnecessary time!

Microcontroller is also known as single-chip microcontroller, the full name is the single-chip microtype computer, referred to as MCU, mainly refers to the 8-bit microcontroller. It is a typical embedded microcontroller, but also an integrated circuit chip, mainly a computer system integrated into a chip, equivalent to a miniature computer, its application areas are very wide, such as the microcontroller for laptop computers or learning machines, can reduce the weight and size of the two, so that users can carry more convenient. The STM32 is a more powerful 32-bit microcontroller, and the biggest difference between it and 8-bit microcontrollers is that it can be programmed not only with registers, but also with official library files, which is not only convenient for programming, but also easier for data transfer.

Embedded is an application-centric, computer technology-based, dedicated computer system for controlling, monitoring or assisting in the operation of machines and devices, with cuttable hardware and software, mainly divided into four types: DSP, microcontroller MCU, microprocessor and SOC. The microcontroller and STM32 belong to the embedded microcontroller MCU, ARM belongs to the embedded microprocessor, where STM32 is a microcontroller developed by relying on ARM, which is a very powerful kind of microcontroller.

With the maturity of 5G and IoT technology, the demand for various low-cost low-power data acquisition equipment has increased significantly, and the microcontroller + peripheral circuit to achieve these functions just meet these technical characteristics. Secondly, with the response policy to support industrial manufacturing, the demand for IoT will only grow. And covering 5G base station construction, ultra-high voltage, intercity high-speed rail and urban rail transit, new energy vehicle charging pile, big data center, artificial intelligence, industrial Internet whole industry chain information services need time to settle and talent continued output.

51 microcontroller performance is limited, peripheral resources are relatively small, less to each development we can use registers to operate, you can not use any library, low clock, run slow, less ram, easy to overflow, cpu no integrated debugging components, for complex programs, we have no way to debug, only print, so it is destined to its application can only be simple needs, of course, we can external ram and rom, I think so to say a system becomes complex, the system is not a microcontroller system, the cost is also a problem.

Than do the function of mcu, stm32 is super cost-effective, for example, a 51 chip 5 yuan, and than this feature-rich stm32 can be as low as 6 yuan, you say I still use 51 what. In the field of arm9 use, when the hot s3c2410 a processor will have more than 20 blocks, and peripheral flash and sdram costs, board design costs, etc., and with stm32 is also more than 20 dollars, less peripheral devices, board design costs are low, software development costs are also high, a need is linux technology, a need or microcontroller technology.
