51单片机秒表课程设计

Ⅰ 51单片机设计简易秒表

你学习板的图呢？我怎么知道用哪些IO口！怎么知道你数码管用什么驱动啊！不然怎么写

Ⅱ 51单片机制作一个秒表

//功能：0~99秒的简易秒表设计，两个静态数码管，定时器采用中断方式
#include"reg51.h"
#define uchar unsigned char
#define uint unsigned int

uchar count=0;//对50ms定时时间进行计数
uchar miao=0; //秒计数器

//函数名：timer_1()
//函数功能：定时器T1的中断函数，T1在工作方式1下每50秒产生中断，执行该中断函数
//形式参数：无
//返回值：无
void timer_1() interrupt 3 //T1的中断类型号为3
{
TH1=(65536-50000)/256; //重新设置T1计数初值高8位
TL1=(65536-50000)%256; //重新设置T1计数初值低8位
count++; //50ms计数器加1
if(count==20) //1s时间到
{
count=0; //50ms计数器清0
miao++; //秒计数器加1
if(miao==100)miao=0; //miao计数到100，则从0开始计数
}
}

bit b=0;
void int_0() interrupt 0
{
if(b == 0){TR1 = 0;b = 1;}
else
{
b = 0;
TR1 = 1;
}
}

void int_1() interrupt 2
{
miao=0;
count = 0;
TH1=(65536-50000)/256;
TL1=(65536-50000)%256;
TR1=1;
}

//函数名：disp
//函数功能：将i的值显示在两个静态连接的数码管上
//形式参数：i，取值范围0~99
//返回值：无
void disp(uchar i)
{
uchar led[]={0xc0,0xf9,0xa4,0xb0,0x99,0x92,0x82,0xf8,0x80,0x90};
//定义0~9显示码，共阳极数码管
P1=led[i/10]; //显示i高位
P2=led[i%10]; //显示i地位
}
void main()
{
TMOD=0x10;//设置T1在工作方式1
TH1=(65536-50000)/256;//设置T1计数初值高8位，定时时间50ms
TL1=(65536-50000)%256;//设置T1计数初值低8位
ET1=1;//开放T1中断允许
EX0 = 1;
IT0 = 1;
EX1 = 1;
IT1=1;
EA=1;//开放总中断允许
TR1=1;//启动T1开始计时
while(1)
{
disp(miao);//显示秒计数器值
}
}

Ⅲ 51单片机完成简易秒表的设计

硬件电路简单，我说下软件部分
用一个定时器定时中断做键盘扫描，数码管用动态扫描的方法，数码管显示和按键处理都放在主程序中进行

Ⅳ 51单片机设计一个秒表，用两个数码管（任意相邻的两个）显示。
