單片機(jī)源程序如下:
- #include <reg52.h>
- #include <intrins.h>
- #define uchar unsigned char
- #define uint unsigned int
- uchar code M[3][8]=
- {
- {0x00,0x7e,0x7e,0x7e,0x7e,0x7e,0x7e,0x00},
- {0x00,0x38,0x44,0x54,0x44,0x38,0x00,0x00},
- {0x00,0x20,0x30,0x38,0x3c,0x3e,0x00,0x00}
- };
- uchar i,j;
- void main()
- {
- P0 = 0xff;
- P1 = 0xff;
- TMOD = 0x01;
- TH0 = (65535-2000)/256;
- TL0 = (65535-2000)%256;
- IT0 = 1;
- IE = 0x83;
- i = 0xff;
- while(1);
- }
- void Key_Down() interrupt 0
- {
- P0 = 0xff;
- P1 = 0x80;
- j = 0;
- i = (i+1)%3;
- TR0 = 1;
- }
- void Show_Dot_Matrix() interrupt 1
- {
- TH0 = (65535-2000)/256;
- TL0 = (65535-2000)%256;
- P1 = _crol_(P1,1);
- P0 = ~M[i][j];
- j=(j+1)%8;
- }
