Abstract: "Principle and application of microcomputer" is the core course of automation major, it is an application-oriented comprehensive professional course, which requires students to master the principle and structure of MCU and C language programming. By increasing the experimental teaching hours and experimental content, the Proteus hardware simulation is added to the experiment; Let the students preview the experiment and enhance their subjective initiative; In the experiment class, we demonstrated to the students how to use Proteus to complete the drawing and simulation of hardware schematic diagram and the programming of keil software. Through the above steps, can greatly enhance the experimental effect, let the students really achieve "soft and hard", so as to achieve the purpose of training applied talents.

Key words: Application oriented, Singlechip, Proteus
