At present, there are more and more products that can be used to develop MCS-51 series single chip puter, 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 is the software design for peripheral interface circuit of AT89S51 experimental board, in order to achieve a variety of development functions. This article describes a variety of routine of development functions, to achieve the control for the various parts of the experimental development board. The system uses the C language, greatly improve the efficiency of developmental debugging; the same time, the resulting documentation is also easy to understand, easy to transplant. Finally, it is necessary todo the software debugging for the system, able pl
