单片机流水灯所有程序

#include<reg52.h>
#define unit unsigned int unit i,j;

sbit led=P1;
sbit led仁PMO;
sbit led2=P1A1;

for(i=xms;i>0;i--)
for(j=110;j>0;j--);
}
用数组实现流水灯循环，依次点亮，然后依次熄灭
#include<reg52.h>
#define uchar unsigned char
//char是字符数组
#define unit unsigned int unit num;
头文件宏定义端口循环永不停止voiddelaymsunitxms用循环左移指令实现流水灯延迟05s下一灯亮led31
#include<reg52.h>
#define uchar unsigned char
//char是字符数组
#define unit unsigned int
uchar num;
sbit led仁PMO;
for(j=110;j>0;j--);
}流水灯

}
}
void delay1s()
包含_crol_函数所在的头文件
赋给a初值Oxfe，即
循环左移指令或a=a<<1;8
void delayms(unit xms)//{
unit i,j;
for(i=xms;i>0;i--)//
for(j=110;j>0;j--);
}用循环左移指令实现流水灯
led3=1;led4=0; delay1s();
led1=~led1;//让发光管状态取反
}
}
用定时器使1灯间隔1s闪烁
#include<reg52.h>
#define uchar unsigned char
#define unit unsigned int
unit num;
#define ucha unsigned char
#define uni unsigned int
{
unit i,j;
for(i=xms;i>0;i--)
for(j=110;j>0;j--);
}没有实现理想的流水灯，问题已解决，见下面程序

#define unit unsigned int

void delayms(unit xms)
{

用数组实现流水灯
