这是做的数码管我做了一个下午时间
里面有单片机的源代码
keil做的程序
有proteus做的仿真
单片机源程序如下:
- #include<reg51.h>
- #define uint unsigned int
- #define uchar unsigned char
- #define SEG P0
- sbit PB1=P2^0;
- sbit PB2=P2^2;
- uchar TAB[]={0xc0,0xf9,0xa4,0xb0,0x99,0x92,0x83,0xf8,0x80,0x98};
- uchar TAB1[]={0x90,0xf8,0x90,0x92,0xa4,0xc0,0xf9,0xb0,0xf9,0x99};
- uchar TAB2[]={0xfe,0xfd,0xfb,0xf7,0xef,0xdf,0xfe,0xfd,0xfb,0xf7,0xef,0xdf};
- void delay_1ms(uint t)
- {
- uint k;
- while(--t)
- for(k=0;k<600;k++);
- }
- main()
- {
- unsigned char i;
- {
- for(i=0;i<10;i++)
- {
- SEG=TAB[i];
- delay_1ms(500);
- if(PB1==0)
- {
- for(i=0;i<10;i++)
- {
- SEG=0xff;
- delay_1ms(800);
- SEG=TAB1[i];
- delay_1ms(800);
- }
- }
- if(PB2==0)
- {
- for(i=0;i<12;i++)
- {
- SEG=TAB2[i];
- delay_1ms(200);
- }
- }
-
- }
-
- }
- }
