Question

求高人给这个程序注释 关于防盗报警系统的C语言程序

#include <reg52.h>
typedef unsigned char uint8;
typedef unsigned int uint16;

sbit s1 =P1^0;sbit s3=P3^2;
sbit light=P3^0;sbitspeaker=P3^1;
sbit zhishi=P1^2;

void baojing()
{
uint8 counter;
TMOD = 0x01;
TH0 = 0xB8;
TL0 = 0x00;
TR0 = 1;
while(s3)
{
if(1 == TF0)
{
TF0 = 0;
TH0= 0xB8;
TL0 = 0x00;
counter++;
}
if(25 == counter)
{
counter = 0;
light = ~light;
speaker=~speaker;
}

}
}

void zs()
{
zhishi=s3;zhishi=s1;
}
void fun()
{
if(s1==0) baojing();

}
void main()
{
zs();
fun();
}

Answer 1

#include <reg52.h> //调用头文件
typedef unsigned char uint8; //简写unsigned char 为uint8
typedef unsigned int uint16;
sbit s1 =P1^0;sbit s3=P3^2; //定义报警触发困槐端口
sbit light=P3^0;sbitspeaker=P3^1; //定义灯和报警器响声端口
sbit zhishi=P1^2; //未用
void baojing()
{
uint8 counter; //计时标志
TMOD = 0x01; //设置中断模式
TH0 = 0xB8; //计时时间高位
TL0 = 0x00; //计时时间低位
TR0 = 1; //中断标志
while(s3)
{
if(1 == TF0)
{
TF0 = 0;
TH0= 0xB8; //重新赋值
TL0 = 0x00;
counter++; //累加
}
if(25 == counter) // 累加到25则清零
{
counter = 0;
light = ~light; //掘尺清效果是灯闪
speaker=~speaker; //效果是声音叫
}
}
}
void zs()
{
zhishi=s3;zhishi=s1; //忽视
}
void fun()
{
if(s1==0) baojing(); //因为该函数只调用一次 所以要么一上电报警 要么程序跑飞
}
void main()
{
zs();
fun();
}
求采纳判前 谢谢
