1、. . 实验题目：实验6无线温度检测实验实验时间：2015.12.14一、 实验目的：学习TI ZStack2007协议栈容，掌握CC2530模块数据传输的实现过程。学习协议栈中关于串口的基本设置和操作。二、 实验原理与程序分析：a) 系统流程图协调器分立ZigBee 无线网络，终端节点自动加入该网络中，然后终端节点周期性的采集温度数据并将其发送给协调器，协调器接收到温度数据后，通过串口将其输出到PC机。如图3.3.1所示。b) l关键代码分析对于协调器而言，只需要将收集到的温度数据通过串口发送到PC 机即可；对于终端节点而言，需要周期性地采集温度数据，采集温度数据可以通过读取温度传感器的数据

2、得到。 温度数据包结构设计该数据包结构体定义如下。typedef union huint8 TEMP4;struct RFRXBUFunsigned char Head;unsigned char value2;unsigned char Tail;BUF;TEMPRETURE;使用一个共用体来表示整个数据包，里面有两个成员变量，一个是数组TEMP，该数组有4元素；另一个是结构体，该结构体具体实现了数据包的数据头、温度数据、数据尾。结构体所占的存储空间也是4个字节。协调器代码：#include OSAL.h#include AF.h#include ZDApp.h#include ZDObje
