篮球计分牌的程序和仿真
单片机源程序如下:
- #include "reg51.h"
- sbit SEG1 = P1^7;

- sbit SEG3 = P1^5;
- sbit SEG4 = P1^4;

- sbit MARK3 = P3^2;
- unsigned char MARK;
- char code table[] = {0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f,0x77,0x7c,0x39,0x5e,0x79,0x71}; //段码
- void delay(unsigned int t)
- {
- while(t--);
- }
- void DigDisplay(void)
- {
- unsigned char i;
- for(i = 0;i < 4;i++)
- {
- switch(i) //位选，选择点亮的数码管，
- {
- case(0):

- }
- delay(100); //间隔一段时间扫描
- P2 = 0x00;//消隐
- }
- }
- void Points(void)
- {

- }

- }
-
