Microputer is therefore often called micro controllers. Now Microputer application has been quite extensive, perated into the munity in all aspects of life. As a new generation of media dissemination of information, LED has been assigning of modern city construction. The design theme is based on Microputer control of the LED display, which is another practice of the application of Microputer. In this paper the design philosophy is: hardware design and software design is independent of each other and to promote each other. This paper will be divided into the following sections to elaborate the design process: ? Design of the hardware ponents: First, introductions on the entire hardware system are made. Then, the entire system is decided into small parts, which is elaborated later and mainly focuses on the design though and content of the system software, according to the functions of hardware. ? Software Design: mainly provides software design and content. ? Postscript and References: In this paper, reference books or literature.
