从调试中看到输出的数据没有问题，但写入单片机STC15W408AS就是不正常
现象：从1210个数据中选出一个，用数码管显示其序号，1-64能正常显示，但往后显示就不正常，比如80显示成16，在KEIL中调试显示发送到数码管的数据是80，但写入芯片后数码管显示为16
程序如下：
#include<intrins.h> //包含"intrins.h"后,不用另外再包含"REG51.H"
#include<stc15w.h>
#include<stdlib.h>
#include<K型热电偶分度表.h> // xdata float K_index[1211] //K型热电偶分度表,float 前不加xdata会出现 error C249: 'DATA': SEGMENT TOO LARGE的提示
unsigned char display_time; //定义变量用于显示次数
unsigned char Data[4]={0,0,0,0}; //第1-4个数码管要显示的数值
unsigned int vreal;
unsigned int index;
float adc;
sbit DA=P1^4; //数码管引脚a,接单片机3脚，P1.4
sbit DB=P1^3; //数码管引脚b,接单片机2脚，P1.3
