Question

请问，单片机控制8个LED灯同时亮 同时灭（间隔1秒）的程序？

Answer 1

#include“reg52.h”
void yanshi()
{
};/////延伸函数一秒根据晶体的频率自己设置也可以用定时器的中断来设置1秒时间也可以用软件定时器；
mian()
{
p1=0xff;
yanshi();
p1=0x00;
yanshi();

}

void timer_10ms() interrupt 1
{
TH0 = (65535 - 10000)/256;
TL0 = (65535 - 10000)%256;
count_1s++;
}

Answer 2

#include "reg52.h"
#define turnon() P0 = 0x00;//共阳极接法
#define turnoff() P0 = 0xff;
unsigned int count_1s;
void main()
{
count_1s = 0;
TH0 = (65535 - 10000)/256;
TL0 = (65535 - 10000)%256;
TMOD = 0x01;
EA = 1;
ET0 = 1;
TR0 = 1;
turnon();
while(1)
{
while(count_1s < 100);
turnoff();
count_1s = 0;
while(count_1s < 100);
turnon();
count_1s = 0;
}
}
void timer_10ms() interrupt 1
{
TH0 = (65535 - 10000)/256;
TL0 = (65535 - 10000)%256;
count_1s++;
}

Answer 3

#include“reg52.h”

void LED_turnon()
{

}
void Delay1s()

{

}
void LED_turnoff()

{

}

void main（）
{
while(1)
{
LED_turnon();

Delay1s();

LED_turnoff();

Delay1s();

}
}
