Abstract
This paper designs MCU-based control system for large LED display screen, which consists of MCU, serial communication circuit, memory circuit, display screen, and the row and column driving circuit. They are widely used in shopping malls, schools, banks, post offices, airports, railway stations, docks, financial and securities markets, cultural centers and other public places for advertisement, news and information releasing, which can display the MXN Chinese characters, characters, numbers and pictures and realize the vertical and horizontal displaying mode. The system based on modular design is easy to expand, convenient to operate and flexible to use. This paper introduces the design scheme of control system, and gives the system simulation results. The practical application shows that the system has the characteristics of stability, reliability and good effects.关键词
