With the rapid development of rapid technological, but also led to the traditional control and LED display and technology update. Large LED dot matrix billboards and traditional advertising is closely integrated into the new media propaganda tool, widely used in the exhibition center, financial markets, hospitals, stadiums, airports, docks, stations, streets, highways, and many other public places display and advertising. This paper presents a simple LED dot matrix display program to achieve a single-chip control, the initial introduction of the basic structure of the microcontroller and LED light-emitting principle and characteristics, focusing on the works of MCU programming method with LED dot matrix display system primarily use the C language source code, and Proteus software simulation, design a 8 × 8 LED dot matrix display based on the 80C51 microcontroller can achieve the words XINGTAI UNIVERSITY rolling display.
