Abstract
In recent years, with computers in the infiltration and the development of large-scale integrated circuits. SCM application is steadily deepening, as it has strong function, small size, low power dissipation, low prices, reliable, easy to use features, it is particularly suited to and control of the system, increasingly widely used in various fields.
This paper introduced the design of digital clock based on SCM of AT89C51, the specific process of how the system hardware and software achieved were detailed description through the design of multifunction digital clock. Describes the application of Proteus's ISIS software of the electronic single-chip system clock to achieve the design and simulation methods in details.The method can not only test the property of the system precisely,but also improve development efficiency and reduce development cost,which values in popularity.
