关于16灯花样流水灯的程序问题 高手请进

我用keil编译程序 生成hex文件 导入89c51芯片以后 接入电路 始终无法得到预期的效果 下面是代码 和我们实验的电路图 请高手指点

//延时
void DelayMS(uint x)
{
uchar i;
while(x--)
{
  for(i=0;i<120;i++);
}
}
//主程序
void main()
{
uchar i;
while(1)
{ //从数组中读取数据送至 P0 和 P2 口显示
  for(i=0;i<136;i++)
  {
   P0=Pattern_P0;
   P2=Pattern_P2;
   DelayMS(100);
  }
}
}



P0=Pattern_P0[i];
   P2=Pattern_P2[i];

我来试试!

100ms,每一秒钟变换10次,你是什么都看不到的,要看见,每秒变换要低于3次,一般采用半秒或一秒

楼上正解。

楼上确实高,这个百度上也有,大家可以去瞅瞅

延时程序带参的,100*120次,是1S多了的啊,主函数位移那个P0,P2不带变量的么
Pattern还没用过,我用的都是crol或cror

呵呵  就是你的数组定义是对的   但是延时函数是带参数的  如二楼说的一样  还有延时程序应该可以吧!

后面循环的时候引用数组的时候没有参数啊P0=Pattern_P0;
   P2=Pattern_P2;
如2楼的:P0=Pattern_P0[i];
   P2=Pattern_P2[i];
另延时函数的时间可以适当长一点,

#include<reg51.h>
#include<reg51.h>
#include<intrins.h>
#define uchar unsigned char
#define uint unsigned int
void delay(uint i)
{   uchar t;
    while (i--)
    {for (t=0;t<120;t++);
    }
   }
   void main()     
   { P1=0xfe;
   while(1)
     {P1=_crol_(P1,1);
  delay(500);
  }   
    }

怎样让他反复亮?
