Title          16*16  Dot  Matrix   Display

Abstract

This subject is about the design of four 16 ×16 array LED electron display screen,AT89S52 MCU (Micro Controller Unit) is the mainly controller, introduced it as the control system of LED array electron display screen with the dynamic design, simulation and the development process. AT89S52 through one line driver 74LS154 and eight row driver 74HC595 actuate the screen dynamic display. The electronic screen can show four Chinese characters static, rolling around and other many kinds of shows state. Through the PC can send any of the Chinese characters with the hzk16 font to MCU for display.

This paper describes the hardware design of the LED dot matrix display、 the principle function of the various parts of the circuit、the corresponding software program design、the PC software design 、 instructions and so on.
