1、s8x8x8LED光立方周渴望南阳理工学院Q418084696功能;通过自定义代码实现LED炫丽动画效果。通过按钮P3-7按钮实现动画与暂停。底面是512个LED分成64组的共阳极由8个74hc573控制，每层64个LED共阴极接在一起，共引出8跟负极与uln2803相连由其控制（这里注意uln280输出高电平LED负极通，低电平LED负极断）。原理：先点亮最下层LED，假设8个74hc573全输出高电平，uln2803控制最下层输出高电平，那么最下层64个LED都点亮，延时10ms到5ms，关断最下层显示开通第二
2、层假设也是8个74hc573全输出高电平，那么倒数第二层64个LED全亮，再延时2ms到5ms那么以此类推每层的LED64个全都会亮，由于从第一层亮到最后一层亮时间小于50ms，由于人眼睛视觉暂留效果，就会觉得是全部层一起亮的，这样就“一起”点亮了512个LED。其实每层的LED亮的数量不一样就组成了各种画面，通过调节定时器，就会有一种绚丽的动画效果。本文使用的是STC12c5a60s2单片机，因为其程序存储空间大，stc89c52rc单片机完全可胜任（验证），只是程序太多要想办法了。原理图：本试验中P0口控制8个
3、74hc573的锁存端，P1控制每层与uln2803相连，P2口传输到74hc573数据。本文使用动态扫苗，基于我之前做的16x16点阵文字移动显示程序，程序简单易懂，但是代码较多。ss程序：#includesbitLA0=P0^0;/*定义8个74hc573锁存脚*/sbitLA1=P0^1;sbitLA2=P0^2;sbitLA3=P0^3;sbitLA4=P0^4;sbitLA5=P0^5;sbitLA6=P0^6;sbitLA7=P0^7;sbitKEY=P3^7;/*定义暂停开关*/
