你说的是设置一个标志，刷新数码管的时候不去计算，计算的时候不去刷新是吗？ ...

一个计算标志, 当在计算时,标志设置为1, 计算结束后设置为0.

刷新程序中检测这个标志为1的话,就显示显示缓冲中的旧值, 如果标志为0, 就将新计算的结果放到显示缓冲并显示.
例如:
一个1ms定时器中断中
1msTimer()
{
if(calcflag){
   将oldvalue刷新到LED
  } else {
   oldvalue=newvalue;
   将newvalue刷新到LED
  }
}

main()
{
while(1){
      calcflag=1;
      开始计算程序；
      计算结束, 获得newvalue；
      calcflag=0;
}
}

按照提示做了优化，另外问一下，像DS18B20这一类采集温度时间比较久的元器件，要怎么样处理程序中需要延 ...

可以用UART来驱动单总线，要加一个二极管和一个电阻，以前Dallas的网站上有一篇**，专门说了这个方法。
这个方法才是王道，完全避免了延时的处理。

但28块钱，实在是低于想象啊，看来真的是应了那句，只有想不到，没有做不到
