返回信息流一个温度传感器的程序，在KEIL c51里的代码为：
#include<reg51.h> //包含单片机寄存器的头文件
#include<intrins.h> //包含_nop_()函数定义的头文件
unsigned char code digit[10]={"0123456789"}; //定义字符数组显示数字
unsigned char code Error[]={"Error!Check!"}; //说明没有检测到DS18B20
unsigned char code Temp[]={"Temp:"};
在AVR里用mega16时头文件改为#include<iom16v.h>，avr里不存在intrins.h，把第二个头文件删除后出现一堆语法错误
#include<iom16v.h>
unsigned char code digit[10]={"0123456789"}; //定义字符数组显示数字
unsigned char code Error[]={"Error!Check!"}; //说明没有检测到DS18B20
unsigned char code Temp[]={"Temp:"}; //说明显示的是温度
