Question

C51单片机跑马灯程序设计

需要完整的程序 C语言的

Answer 1

#include <reg51.h>
void Delay()
{
unsigned char i,j;
for (i=0;i<255;i++)
for(j=0;j<255;j++);
}
void main()
{
unsigned char i;
unsigned char temp;
P1=0xff;//p1置1，熄灯//
while(1)
{
temp=0x01;//赋值temp 左右有一位为一//
for(i=0;i<8;i++)
{
P1=~temp;//将temp取反后送p1输出//
Delay();//调用延时//
temp=temp<<1;//temp中数据左移一位//
}
}
}

Answer 2

是不是这种
#include<reg52.h>
#include<intrins.h>
#define uchar unsigned char
#define uint unsigned int
void delay(uint k )
{uint i,j;
for(i=0;i<k;i++)
{for(j=0;j<125;j++)
{;}}
}
void main()
{
uchar OUTDATA=0Xfe;
uchar i;
while(1)
{
for(i=0;i<7;i++)
{OUTDATA=_crol_(OUTDATA,1);
P0=OUTDATA;
delay(1000);
}
OUTDATA=0X7f;
for(i=0;i<7;i++)
{OUTDATA=_cror_(OUTDATA,1);
P1=OUTDATA;
delay(1000);
}
OUTDATA=0Xfe;
for(i=0;i<7;i++)
{OUTDATA=_cror_(OUTDATA,1);
P0=OUTDATA;
delay(1000);
}
OUTDATA=0X7f;
for(i=0;i<7;i++)
{OUTDATA=_crol_(OUTDATA,1);
P1=OUTDATA;
delay(1000);
}
}
}

Answer 3

#include<reg52.h>
#include<intrins.h>
#define uint unsigned int
#define uchar unsigned char
void delay (uint z)
{
uint x,y;
for(x=z;x>0;x--)
for(y=110;y>0;y--);
}
void main()
{
uchar a;
a=0xfe;
while(1)
{
a=_cror_(a,1);
P0=a;
delay(200);
}
}
