你要自己改哦 因为型号，发光的个性也不一样啊
我把我以前写的给你，你自己调试一下看
#include
#include
#define uint unsigned int
#define uchar unsigned char
void delay(uint) ;
uchar temp,i;
void main()
{
while(1)
{
for(b=0;b<2;b++)
{
if(temp!=0x00)
{
temp=0x7f;
P1=temp;
delay(1000);
temp=0x80;
for(i=0;i<7;i++)
{
temp=~_iror_(temp,1);
delay(1000);
P1= temp;
delay(1000);
temp=~temp;
}
}
temp=0xfe;
P1=temp;
delay(1000);
temp=0x01;
for(i=0;i<7;i++)
{
temp=~_irol_(temp,1);
delay(1000);
P1= temp;
delay(1000);
temp=~temp;
}
}
temp=0xff;
P1=temp ;
delay(8000);
temp=0;
delay(1000);
temp=0xff;
delay(1000);
temp=0;
delay(1000);
temp=0xff;
delay(1000);
}
}
void delay(uint z)
{
uint x,y;
for(x=z;x>0;x--)
for(y=120;y>0;y--);
}
这个最简单的办法是用一个数组 一次循环就搞定了 就是你这个间隔一秒 要用定时器来做？
我这里有啊，分少了。
