标题: 模拟花样广告灯显示实验
是用51hei单片机开发板 电路图详见：http://www.51hei.com/f/51hei-5.pdf   p1口上面接8个灯.

1. 
   
2. #include<reg52.h>
   
3. #define uchar unsigned char
   
4. #define uint unsigned int
   
5. uchar code LED1[]={0x7f,0xbf,0xdf,0xef,0xf7,0xfb,0xfd,0xfe};
   
6. uchar code LED2[]={0xfe,0xfd,0xfb,0xf7,0xef,0xdf,0xbf,0x7f};
   
7. uchar code LED3[]={0x7e,0xbd,0xdb,0xe7,0xe7,0xdb,0xbd,0x7e};
   
8. uchar code LED4[]={0x7f,0x3f,0x1f,0x0f,0x07,0x03,0x01,0x00};
   
9. uchar code LED5[]={0xfe,0xfc,0xf8,0xf0,0xe0,0xc0,0x80,0x00};
   
10. //============
    
11. void delay(unsigned int k)
    
12. {
    
13. unsigned int i,j;
    
14. for(i=0;i<k;i++){
    
15. for(j=0;j<121;j++)
    
16. {;}}
    
17. }
    
18. //====================
    
19. void main(void)
    
20. {uchar cnt;
    
21. while(1)
    
22. {
    
23. for(cnt=0;cnt<8;cnt++)
    
24. {P1=LED1[cnt];
    
25. delay(200);}
    
26. //=======
    
27. for(cnt=0;cnt<8;cnt++)
    
28. {P1=LED2[cnt];
    
29. delay(200);}
    
30. //===========
    
31. for(cnt=0;cnt<8;cnt++)
    
32. {P1=LED3[cnt];
    
33. delay(200);}
    
34. //==========
    
35. for(cnt=0;cnt<8;cnt++)
    
36. {P1=LED4[cnt];
    
37. delay(200);}
    
38. //=========
    
39. for(cnt=0;cnt<8;cnt++)
    
40. {P1=LED5[cnt];
    
41. delay(200);}
    
42.     }
    
43. }
