实验6—无线温度检测实验

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协议栈内容 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 实验原理及程序分析 a a 系统流程图系统流程图 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 2 b b 关键代码分析关键代码分析 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 得到 3 温度数据包结构设计 该数据包结构体定义如下 typedef union h uint8 TEMP 4 struct RFRXBUF unsigned char Head unsigned char value 2 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 ZDObject h include ZDProfile h include include Coordinator h include DebugTrace h if defined WIN32 include OnBoard h endif include hal led h include hal lcd h include hal key h include hal uart h const cId t GenericApp ClusterList GENERICAPP MAX CLUSTERS GENERICAPP CLUSTERID const SimpleDescriptionFormat t GenericApp SimpleDesc 4 GENERICAPP ENDPOINT GENERICAPP PROFID GENERICAPP DEVICEID GENERICAPP DEVICE VERSION GENERICAPP FLAGS GENERICAPP MAX CLUSTERS cId t GenericApp ClusterList 0 cId t NULL endPointDesc t GenericApp epDesc byte GenericApp TaskID byte GenericApp TransID unsigned char uartbuf 128 void GenericApp MessageMSGCB afIncomingMSGPacket t pckt void GenericApp SendTheMessage void static void rxCB uint8 port uint8 event static void rxCB uint8 port uint8 event HalUARTRead 0 uartbuf 16 if osal memcmp uartbuf 16 HalUARTWrite 0 uartbuf 16 void GenericApp Init byte task id halUARTCfg t uartConfig GenericApp TaskID task id GenericApp TransID 0 GenericApp epDesc endPoint GENERICAPP ENDPOINT GenericApp epDesc task id GenericApp epDesc simpleDesc SimpleDescriptionFormat t GenericApp epDesc latencyReq noLatencyReqs afRegister uartConfig configured TRUE uartConfig baudRate HAL UART BR 115200 uartConfig flowControl FALSE uartConfig callBackFunc NULL HalUARTOpen 0 UINT16 GenericApp ProcessEvent byte tadk id UINT16 events afIncomingMSGPacket t MSGpkt if events while MSGpkt switch MSGpkt hdr event case AF INCOMING MSG CMD GenericApp MessageMSGCB MSGpkt break default break osal msg deallocate uint8 MSGpkt MSGpkt afIncomingMSGPacket t osal msg receive GenericApp TaskID return events SYS EVENT MSG return 0 void GenericApp MessageMSGCB afIncomingMSGPacket t pkt unsigned char buffer 2 0 x0A 0 x0D TEMPRETURE tempreture switch pkt clusterId case GENERICAPP CLUSTERID osal memcpy HalUARTWrite 0 uint8 HalUARTWrite 0 buffer 2 break 终端节点编程 读取温度 int8 readTemp void static uint16 reference voltage static uint8 bCalibrate TRUE uint16 value int8 temp ATEST 0 x01 TR0 0 x01 ADCIF 0 ADCCON3 HAL ADC REF 115V HAL ADC DEC 256 HAL ADC CHN TEMP while ADCIF 6 ADCIF 0 value ADCL value uint16 ADCH 4 if bCalibrate reference voltage value bCalibrate FALSE temp 22 value reference voltage 4 return 22 终端节点事件处理与无线数据发送 UINT16 GenericApp ProcessEvent byte tadk id UINT16 events afIncomingMSGPacket t MSGpkt if events while MSGpkt switch MSGpkt hdr event case ZDO STATE CHANGE GenericApp NwkState devStates t MSGpkt hdr status if GenericApp NwkState DEV END DEVICE GenericApp SendTheMessage osal set event GenericApp TaskID SEND DATA EVENT default break osal msg deallocate uint8 MSGpkt MSGpkt afIncomingMSGPacket t osal msg receive GenericApp TaskID return events SYS EVENT MSG if events osal start timerEx GenericApp TaskID SEND DATA EVENT 1000 return events SEND DATA EVENT return 0 7 void GenericApp SendTheMessage void unsigned char theMessageData 10 EndDevice int8 tvalue TEMPRETURE tempreture tempreture BUF Head tvalue readTemp tempreture BUF value 0 tvalue 10 0 tempreture BUF value 1 tvalue 10 0 tempreture BUF Tail C afAddrType t my DstAddr my DstAddr addrMode afAddrMode t Addr16Bit my DstAddr endPoint GENERICAPP ENDPOINT my DstAddr addr shortAddr 0 x0000 AF DataRequest HalLedBlink HAL LED 2 0 50 500 三 实验步骤及结果 打开ZigBee2530部分 exp zigbee 无线温度检测实
