The Design Of Experimental Development System Based On AT89S51 Single Chip Microcomputer

As the single chip microcomputer technic is used wider and wider in all areas, many manufacturers of integrated circuit have developped all kinds of single chip microcomputer one after another. Among the many members of single chip microcomputer family, the MCS-51 series of single chip microcomputer has quickly gained the market share and become the main stream in the national application area of single chip microcomputer with their excellent performance, mature technic, high reliability and high cost performance. At present, there are more and more products that can be used to develop MCS-51 series single chip microcomputer, and the development systems and softwares matched to them are improved day by day. Therefore, we can conveniently use available resources to develop all kinds of application system used for different aims.This project designs an experiment of single chip microcomputer development system which can be applied to the experiments for specialized core course, professional course (Principle and Application of single chip microcomputer,Interface technology of single chip microcomputer,etc), courses design and graduate design. The experimental borad is designed according to the experiment in the single chip microcomputer teaching material which can implement simple test experiments. This paper includes the detailed design of the hardware system and the application of assembly language in the basic control.
