协议栈工作流程和无线收发控制

此起到事半功倍的效果，经过多名初学者学习所积累总结出的经验，希望对您有所帮定义了NWK（网络层）、APS（应用程序支持子层）、APL（应用层）技术规范。ZigBee协议栈是协议的实现，可以理解为代码，函数库，供上层应用调用，协议较的层与一个功能模块给你调用。你需要关心的就是你的应用逻辑，数据从哪里到哪里，怎么，afStatus_tAF_DataRequest(afAddrType_tendPointDesc_tuint16uint16uint8uint8uint8uint8radiusuint16len,解压..\相关资料与软件\Zigbee开发软件\ZStack-CC2530-2.3.0-1.4.0协议栈安装文hal，zcl等库的代码 SampleApp.eww,从软件开发专业角度讲建议大家工程到非中文 MAC：MACMAC配置文件及其MACLIB Profile：Applicationframework应 ，包含AF层处理函数文 及Z-Stack相关配置信息。ZMac：MAC层 Output：输出文件，由IARIDE自动生 鸟，具体使用请参考相关资料与软件\Zigbee参考资料\SourceInsight使用.pdf。下进行注释，方便习惯看源码的学习。我建议大家先的文章，再阅读一次源码加自己添加的应用任务程序在Zstack中的调用过程：main()--->osal_init_system()--->osalInitTasks()--->intmain(void{osal_int_disable(INTS_ALL);//关闭所有中断 //检查电压是否正常InitBoard(OB_COLD); //初始化I/O，LED、Timer等 //初始化各硬件模块osal_nv_init(NULL); //初始化Flash器 //初始化MAC层 #ifndef//SincetheAFisn'tatask,callit'sinitializationroutineosal_int_enable(InitBoard(OB_READY#ifdef #ifdef/*IfWDTisused,thisisagoodcetoenableit.*/WatchDogEnable(WDTIMX);osal_start_system();NoReturnfromherereturn0;//Shouldn'tget}//操作系统。进去后可不会回来了。在这里，我们重点了解2个函数：初始化操作系统运行操作系统单击右键——gotodefinitionof…，便可以进入函数。发现里面有6个初始化函数，这里我们只关心osalInitTasks();任务初始化函数，继续由该函数进入。voidosalInitTasks(void{uint8taskID=tasksEvents=(uint16*)osal_mem_alloc(sizeof(uint16) osal_memset(tasksEvents,0,(sizeof(uint16) //任务优先级由高向低依次排列，高优先级对应taskID的值反而小makInit(taskID++);//makInit(0)，用户不需考虑nwk_init(taskID++); Hal_Init(taskID++); //Hal_Init(2)，用户需考虑#ifdefined(MT_TASK) MT_TaskInit(taskID++);APS_Init(taskID++ #ifdefined(ZIGBEE_FRAGMENTATION)APSF_Init(taskID++);ZDApp_Init(taskID++ #ifdefined(ZIGBEE_FREQ_AGILITY)||defined(ZIGBEE_PANID_)ZDNwkMgr_Init(taskID++);SampleApp_Init(taskID);SampleApp_Init_Init(5)，用户需考虑。}们应用协议栈例程的必要函数，用户通常在这里初始化自己的东西。至此，voidosal_start_system(void{#if!defined(ZBIT)&&!defined(UBIT)for(;;)//ForeverLoop{uint8idx= Hal_ProcessPoll();TIMERdoif(tasksEvents[idx])//Taskishighestprioritythatis{ }}while(++idx if(idx {uint16events;events=tasksEvents[idx]; tasksEvents[idx]=0; HAL_EXIT_CRITICAL_SECTION(intState);//退出临界区eventstasksArr[idx])(idx,events tasksEvents[idx]|=events;//保存未处理的Addbackunprocessedeventstothecurrenttask. }#ifdefined(POWER_SAVINGelse//Completepassthroughalltaskeventswithno{osal_pwrmgr_powerconserve();//Puttheprocessor/systeminto}}}我们看一下events=tasksEvents[idx];进入tasksEvents[idx]数组定义，发现恰好是是初始化与调用的关系。taskID把任务联系起来了。voidSampleApp_Init(uint8task_id){恢复其网络状态，而不需要重新建立或者加入网络了.这里需要设置NV_RESTORE宏定义。#ifdefined(BUILD_ALL_DEVICES)if(readCoordinatorJumper())zgDeviceLogicalType=ZG_DEVICETYPE_COORDINATOR;zgDeviceLogicalType=ZG_DEVICETYPE_ROUTER;#endif//BUILD_ALL_DEVICES#ifdefined(HOLD_AUTO_START)SampleApp_Periodic_DstAddr.addrMode=(afAddrMode_t)AddrBroadcast;//广播SampleApp_Periodic_DstAddr.endPoint=SAMPLEAPP_ENDPOINT;//指定端点号=Setupfortheflashcommand'sdestinationaddressGroup1SampleApp_Flash_DstAddr.addrMode=(afAddrMode_t)afAddrGroup;//组寻址SampleApp_Flash_DstAddr.endPoint=SAMPLEAPP_ENDPOINT;//指定端点号SampleApp_Flash_DstAddr.addr.shortAddr=SAMPLEAPP_FLASH_GROUP;//组号0x0001SampleApp_epDesc.endPoint=SampleApp_epDesc.task_id=&SampleApp_TaskID;//SampleApp描述符的任务ID //SampleApp简单描述符(SimpleDescriptionFormat_t*)&SampleApp_SimpleDesc;SampleApp_epDesc.latencyReq=noLatencyReqs;//延时策略AFendpointdescriptionAF,AFEPafRegister(&SampleApp_epDescRegisterForKeys(SampleApp_TaskIDBydefault,alldevicesstartoutinGroup1SampleApp_Group.ID=0x0001;//组号osal_memcpy(SampleApp_G,"Group1",7aps_AddGroup(SAMPLEAPP_ENDPOINT,&SampleApp_GroupAPS#ifdefined(LCD_SUPPORTEDHalLcdWriteString("SampleApp",HAL_LCD_LINE_1LCD，显示提示信息}uint16SampleApp_ProcessEvent(uint8task_id,uint16events{ingMSGPacket_t(void)task_id;//Intentionallyunreferencedifevents&SYS_EVENT_MSG{MSGpkt=( ingMSGPacket_t*)osal_msg_receive(SampleApp_TaskID);while(MSGpkt){switch(MSGpkt->hdr.event{ReceivedwhenakeyispressedcaseKEY_CHANGE://按键SampleApp_HandleKeys(((keyChange_t*)MSGpkt)->state,*)MSGpkt)->keys//Receivedwhenamessagesisreceived(OTA)forthis ING_MSG_CMD://接收数据,调用函数AF_DataRequest()接收据SampleApp_MessageMSGCB(MSGpkt 理//ReceivedwheneverthedevicechangesstateinthecaseZDO_STATE_CHANGE:ZDO_STATE_CHANGESampleApp_NwkState=(devStates_t)(MSGpkt-//if((SampleApp_NwkState==DEV_ZB_COORD)if((SampleApp_NwkState==DEV_ROUTER)||(SampleApp_NwkStateDEV_END_DEVICE){osal_start_timerEx(}{//Deviceisnolongerinthe}}//Releasethememory//处理完了，释放消息占用的内osal_msg_deallocate((uint8*)MSGpktMSGpkt= ingMSGPacket_t*)osal_msg_receive(SampleApp_TaskID}returnunprocessedevents//返回未处理的return(events^SYS_EVENT_MSG);}//Sendamessageout-Thiseventisgeneratedbya//(setupinif(events&SAMPLEAPP_SEND_PERIODIC_MSG_EVT{//处理周期 //Setuptosendmessageagaininnormalperiod(+alittlejitter)(SAMPLEAPP_SEND_PERIODIC_MSG_TIMEOUT+(osal_rand()&0x00FF)));//returnunprocessedeventsreturn(events^}//Discardunknowneventsreturn0;}void ingMSGPacket_t*pkt{bytebuf[3];switchpkt->clusterId{caseSAMPLEAPP_PERIODIC_CLUSTERID://收到广播数据osal_memset(buf,0,3);osal_memcpy(buf,pkt->cmd.Data,2);//数据到缓冲区if(buf[0]=='D'&& //判断收到的数据是否为{HalLedBlink(HAL_LED_1,0,50,500);Led1500ms
