Abstract
LED have e a high speed development of emerging industries, and broad prospects. The design based on single chip puter AT89S52 was introduced 16 * 16 lattice LED scrolling display of Chinese characters design. Which focus on LED dot matrix display the functions of the parts of the hardware design, hardware circuit and the principle and the corresponding software program design, and detaiLED instructions and work processes.
The design is divided into six parts, including the main content for the system overall analysis, the system hardware design, system software design three parts. System overall analysis is the foundation of the design; System hardware design is the key and core part of the paper, first of all, this part simply described the working principle of the system hardware, and attach a system block diagram of hardware design, the design is discussed the application of the hardware interface technology and the function of each interface module and working process; Software design is a crucial part of the system is running.
The dominant idea of the design is bination of software and hardware, on the basis of hardware, design of each function module. This design and strong practicability, simple operation, strong extended functionality. This display design with small size, less hardware, circuit structure is simple and easy to implement, etc.
Keywords: MCU; LED; Lattice; Chinese character demonstrates
