供参考：

#include <REGX52.H>
unsigned char NixieTable[] = { 0x3F,0x06,0x5B,0x4F,0x66,0x6D,0x7D,0x07,0x7F,0x6F };//修改，末尾加 '; '
void Nixie(unsigned char Location ,unsigned char Number)//修改，Number 添加数据类型
{
    switch (Location)
    {
         case 1:P2_4 = 1; P2_3 = 1; P2_2 = 1; break;
         case 2:P2_4 = 1; P2_3 = 1; P2_2 = 0; break;
         case 3:P2_4 = 1; P2_3 = 0; P2_2 = 1; break;
         case 4:P2_4 = 1; P2_3 = 0; P2_2 = 0; break;
         case 5:P2_4 = 0; P2_3 = 1; P2_2 = 1; break;
         case 6:P2_4 = 0; P2_3 = 1; P2_2 = 0; break;
         case 7:P2_4 = 0; P2_3 = 0; P2_2 = 1; break;
         case 8:P2_4 = 0; P2_3 = 0; P2_2 = 0; break;
    }
    P0 = NixieTable[Number];
}
void main()
{
    Nixie(7, 2);
    while (1)
    {

    }
