China has now become the world's largest electronics manufacturing base, and as the core component of many electronic products, the market for microcontrollers is growing rapidly and competition is becoming increasingly fierce. Microcontrollers have the advantages of strong control functions, low operating voltage, good integration, small size, etc. They are mainly used in the following fields: medical equipment field, automotive electronic equipment, mechatronics, automated office, aerospace field, cutting-edge weapons and defense military field, computer communication field ...... microcontroller developers want to take an advantageous position in the fierce To occupy an advantageous position in the fierce competition in the market, it is necessary to understand the following microcontroller development skills:
I. Improve the efficiency of C programming language

　　Initially, microcontroller development using assembly language, although this is a low-level language, but at that time more in line with the operation of the hardware state. With the increasing demand for microcontrollers and the rising complexity, the use of assembly language alone to create programs would have been extraordinarily cumbersome and reduced development efficiency. As a result, most fields are now choosing to program in C. C programming has therefore become a key study in microcontroller development. Therefore, to improve programming efficiency, it is important to fully understand the C language and the C compiler in MCU systems.

II. Suppressing program bugs

　　During MCU development, if an error code occurs, it can have a serious impact on the working path, reducing the quality and usage performance of the MCU or even destroying the entire working state. Therefore, when involved in microcontroller development work, must take into account all aspects, that is, a variety of physical parameters, which include: structural parameters, excitation parameters, process parameters and resource parameters, try not to appear BUG, improve the quality of the microcontroller.

Third, improve the single-chip machine anti-interference

　　This is very important, but there is also a certain degree of difficulty. To improve the anti-interference, the interference path should be completely cut off. The designer can solve this problem by connecting the compatible and to the position of both ends of the interference source. In addition, a comprehensive test of the system's operational status is required, including power-up tests, power-down tests, ESD tests, EFT tests, ageing tests, etc. The electromagnetic immunity and anti-static capability of the microcontroller can also be tested by rubbing the microcontroller's contact ports.

　　With the development of information technology, microcontroller has become an indispensable presence in various fields of electronic products, of which business opportunities are unlimited. At present, the domestic microcontroller brand has gradually risen to form a strong force to confront foreign brands, the domestic brand to expand its market share is only a matter of time. Microcontroller developers should continue to improve their strength, understanding, learning more microcontroller development skills, in order to seize the opportunity to develop and capture a larger market.
