 PAGE \* MERGEFORMAT 2 PAGE  -  PAGE 2 - 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。 关键词：光立方；74HC573； STC12C5A60S2；ULN2803 ABSTRACT LED Cube is a three-dimensional cube -shaped LED light-emitting diode display device using a single color or multi-color LED, can produce complex 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 truly complex 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 successfully tested a dynamic display and control light cube .
