| After years of development,Micro Control Unit (MCU) is widely used in every field of human social life with progress in its performance and thousands of models.The course has become an important one in the major of computer, automation and control, and specialized in electronic and information engineering. The course,with strong theory and practice, should closely integrate theory and experiment together in actual teaching.Becides the grasp of theoretical knowledge,the students can grasp MCU structure principle and application skills better through a series of experiments such as the design of hardware circuit, programming, simulation and testing and so on. With the development of interface chip technology, the supply of programming simulation experiment instrument cannot completely meet university course's teaching and learning needs incurrent marketing,so the purchase of Single-chip simulation system with low cost, advanced technology, the microcontroller programming open source has important realistic significance to the education and the train of talent in Micro Control Unit course.With the idea of modular structure design,the paper carefully designs and develops the microcontroller programming-simulation experiment system considering the actual demand of the present teaching of SCM in simulation experiment system programming. The microcontroller programming-simulation experiment system includes the PC and single-chip microcontroller programming control software and programming simulation experiment board. PC and single-chip microcontroller programming control software can detecte Single-chip connected to Single-chip programming simulation experiment board, control chip microcontroller programming to erase, write, read target in the ROM chip program,and show in the control interface with HEX files (.HEX documents). The simulation experiment system can run the program written in microcontroller and show the real result. single-chip microcontroller programming control software and programming simulation experiment board compose of a complete microcontroller programming simulation experiment system.The microcontroller programming-simulation experiment system is developed in the environment of Visual C++ IDE. MCU on the microcontroller programming simulation experiment broad use the AT89S51 single-chip launched by American Atmel company,which has wide use, strong compatibility and low price. This series of single-chip microcontroller has integrated not only basic function of the components in the system but also programmable (ISP) function.The selection of the MCU can effectively reduce the system's technology and cost, and increase the reliability of the system at the same time. The microcontroller programming-simulation experiment system has stable performance and comprehensive function.Modular design ideas realize the function of microcontroller programming-simulation experiment system separately. Using the programmable individually simulation experiment system, you can learn the programme from the theory, inquire process of single-chip microcontroller subroutine library at real-time,and enter the simulation provided by this system.It can qualified various experimental and practical stage of students' experiment courses, the electronic design contest etc,which can contribute to the self-developed experiment and cultivate students' innovative spirit and creativity.This paper firstly microcontroller programming simulation system, and introduces the necessity and feasibility of the microcontroller programming- simulation experiment system consisting of various modules and the design principle and realization method, and the key to paper work done that, Then discusses the modular microcontroller programming-simulation experiment system mainly completed the overall design, selection and system programming simulation MCU, general description logic structure design and implementation of the simulation experiment system programming and MCU control software programming, Full of three modules microcontroller simulation experiment system are introduced, namely: programmable control section, subroutine query and programming simulation experiment. Expounds microcontroller programming design of simulation experiments, including design and programming ISP online programming function design, as well as the basic experimental modules of design of each part of the work principle, the hardware circuit are connected principle. Finally discussed using the system improved experiment teaching method, through some specific experimental system, introduces microcontroller programming- simulation experiment system operation process and to do this experiment. |
