摘　　要：设计一种以STC89C52为核心的8×8点阵显示系统,该系统的行和列分别通过两块74HC595芯片驱动,利用取模软件取模结合编程可实现汉字、图形和字符的动态显示,按下按键,显示停止并且蜂鸣器报警提示;弹起按键,点阵继续循环显示。通过Proteus仿真可以测试程序的可行性,最后进行电路的制作。该系统便于扩展,以8×8点阵为基础模块实现了大屏复杂内容的显示。A kind of display system with 8 × 8 dot-matrix shall be designed based on STC89C52.The lines and columns of this system are driven respectively by two pieces of 74HC595 chip.Chinese characters,graphics and normal characters of dynamic display can be realized by modulus combination with programming based on fetching-model software.When the button is turned off,stop-sign and buzzer alarming are displayed,when button is turned on,dot-matrix which continue looping is displayed.The program feasibility can be tested by Proteus simulation before circuit is made.This system is expanded conveniently,and realized displaying complex content on large-screen based on 8 × 8 dot-matrix module.
