文档介绍：摘要
光立方是LED发光二极管构成的正方体形状的立体显示装置,使用单色或多色发光管,可以产生复杂灵活、十分有吸引力的显示效果,包括单一立体图形的静态显示、动态显示和多种图形的交替显示等多种显示方式,未来甚至可能以此为基础,真正实现复杂图像的三维显示。光立方是一个集实际型、经济型、性价比高的艺术品, 它不仅仅局限于装饰,更是能够帮助更好的学习 c语言实际应用、满足单片机爱好者对基于单片机控制系统电路设计研究的好课题。
本设计采用的是8*8*8的光立方设计方案,即立方体的长宽高各是由八个LED灯排列而成的,长宽高大概是14cm*14cm*20cm,整个系统主要分为三个模块:控制模块驱动模块显示模块;主控芯片为60K STC12C5A60S2,驱动电路采用的是cmos锁存器74HC573数字芯片以及达林顿管驱动器ULN2803,显示模块为512个LED焊接成的光立方。经过试验本方案成功实现了光立方的动态显示及控制。

ABSTRACT
LED Cube is a three-dimensional cube -shaped LED light-emitting diode display device using a single color or multi-color LED, can plex and flexible, very attractive display, including a single static display three-dimensional graphics , dynamic display and a variety of graphic display and other display alternately , even it will be a basis for plex three-dimensional image display in the future. Light Cube is a set of practical , economical , cost-effective high art, it is not limited to decoration, it is able to help better learning c language practice , it is a good topic for Electronics enthusiasts to design a circuit of microcontroller based control system .
   This design uses a light cube design 8 * 8 * 8 , ie the length , breadth and height of cube is made up of eight LED lights arrayed , the length and breadth is about 14cm * 14cm * 20cm, the whole system is divided into three modules : a control module driver module and display module ; master chip 60K STC12C5A60S2, drive circuit uses a digital chip cmos latch 74HC573 and Darlington driver ULN2803, LED display module 512 welded into the light cube . The program essfully tested a dynamic display and control light cube .
