【摘要】 本次设计使用512个LED灯制作8*8*8的LED立方体，命名为光立方。采用

STC12C5A60S2芯片作为主控，8个74HC573锁存器和一个ULN2803芯片扩展I/O口，作为外围控制。通过编程控制I/O口，点亮指定的LED灯，使得显示不同的画面。8*8*8光立方因点亮LED灯将会形成各种图形，如爱心、数字、雨滴、正方体等十几种画面。整个立体呈现不同的造型和图案，动画衔接完美，使其变得美轮美奂、绚丽多彩，立体感十足。此外，我们还可以外接音频输入，通过AD采样，快速傅里叶变换FFT，可以让光立方显示音频频谱。经过系统测试，最终达到设计要求。

Based on STC12C5A60S2 of the Light Cube Design

【Abstract】:The 8*8*8 LED cube is made of 512 LED lights，named Light Cube which

used STC12C5A60S2 as main control chip，it has 8 74HC573 latches extended I/O ports,and a ULN2803 chip as out control. Through programming control I/O port, the LED light. 8 * 8 * 8 cubic light for light leds will form a variety of graphics, such as love heart,numbers,rain,cube and so on. animation, cohesion is perfect, stereo sense is dye-in-the-wood. In addition, we also can external audio input, through the AD sampling, fast Fourier transform FFT, can let light cube display audio spectrum. After the system test, finally to meet the design requirements.
