标题: 51单片机控制16x16点阵程序


单片机源程序如下:
  1. #include<reg51.h>
  2. #define uchar unsigned char
  3. sbit R=P2^0;
  4. sbit CLK=P2^1;
  5. sbit STB=P2^2;
  6.   code uchar a[]={0x20,0x08,0x20,0x10,0x20,0x10,0x25,0xFF,0x24,0x40,0x24,0x42,0x24,0x44,0x24,0x28,
  7. 0x24,0x28,0x24,0x10,0x24,0x10,0x24,0x28,0x20,0x24,0x20,0x42,0x28,0x41,0x10,0x00};
  8. code uchar b[]={0x20,0x80,0x21,0xE0,0x20,0x3E,0x24,0x20,0x24,0x20,0x24,0x20,0x25,0xFF,0x24,0x30,

  10. code uchar c[]={0x00,0x00,0x00,0x07,0x02,0x02,0x02,0x02,0x02,0x02,0x02,0x02,0x42,0x7F,0x00,0x00,} ;

  28.          CLK=1;
  29.          }
  30. }
  31. void main()
  32. {
  33. int num,n=0,m=0,j;
