Abstract: This article introduces the AT89C51 MCU-based single-color LED display control characters show the basic principles of the hardware and software and systems design. First outlined the LED display profile and development, and the ranks of LED display module driver made a brief description of principles followed by emphasis on analysis and design of a microcontroller control system hardware and related devices, explained the principle; Final completion of the system's display drivers, the system main program, and list some of the source. The results showed that the system can achieve sub-screen display and scanning the left scan showed that the effect of, and a serial data input, parallel and synchronized clock output data for the circuit can greatly reduce the input and output MCU I / O of the occupation, increase data transmission Rate.
