代码：

#include <REGX52.H>
#include "intrins.h"

unsigned char NixieTable[] = {0x3F,0x06,0x5B,0x4F,0x66,0x6D,0x7D,0x07,0x7F,0x6F,0x77,0x7C,0x39,0x5E,0x79,0x71,0x00};

void Delay1ms(unsigned int xms)		//@11.0592MHz
{
	unsigned char i, j;
	
	while(xms--)
	{
		_nop_();
		i = 2;
		j = 199;
		do
		{
			while (--j);
		} while (--i);
	}

	
}

void Nixie(unsigned char Location,Number)
{
	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;

	P0 = NixieTable[Number]; 

			
}


void main(void)
{
	Nixie(7,5);
