单片机源程序如下:
#include <regx51.h>
#include "intrins.h"
unsigned char NixieTable[] = {0xc0, 0xf9, 0xa4, 0xb0, 0x99, 0x92, 0x82, 0xf8, 0x80, 0x90};

void Delay1ms(unsigned int xms)             //@12.000MHz
{
      unsigned char i, j;
      while(xms--)
      {
      i = 2;
      j = 239;
      do
      {
            while (--j);
      } while (--i);
      }
}

void Nixie(unsigned char location,unsigned char number)
{
            switch(location)
      {
            case 1:P2_0 = 1; P2_1 = 0; P2_2 = 0; P2_3 = 0; break;
            case 2:P2_0 = 0; P2_1 = 1; P2_2 = 0; P2_3 = 0; break;
            case 3:P2_0 = 0; P2_1 = 0; P2_2 = 1; P2_3 = 0; break;
            case 4:P2_0 = 0; P2_1 = 0; P2_2 = 0; P2_3 = 1; break;
      }
      P0 = NixieTable[number];
      Delay1ms(10);
}

void main()
{
      while(1)
      {
            Nixie(1,1);
            Nixie(2,2);
            Nixie(3,3);
            Nixie(4,4);
      }
}

加个消隐处理就可以了，没多复杂。
