光立方8*8*8_方案STC89C52RC+ULN2803A+U74HC573G，共520顆LED，調試階段，還有一些很多需要優化的地方，大家多多指點，相互學習，提高大家技術技能。
Altium Designer畫的原理圖和PCB圖如下：(51hei附件中可下載工程文件)
單片機源程序如下:
- #include<reg52.h>
- #define uint unsigned int
- #define uchar unsigned char
- #define num 93
- #define wait 2
- #define X P2
- #define Y P0
- #define Z P1
- uchar i,j,k;
- uint count,temp;
- uchar Z_Seg[8] ={0x01,0x02,0x04,0x08,0x10,0x20,0x40,0x80}; //共陽極
- uchar Y_Seg[8] ={0x01,0x02,0x04,0x08,0x10,0x20,0x40,0x80}; //選擇使能8個74HC573芯片，高電平隨輸入而輸出，低電平鎖存
- uchar code display[]={
-
- 0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,
