ZigBee协议栈初始化网络启动流程ZigBee的基本流程：由协调器的组网（创建PANID），终端设备和路由设备发现网络以及加入网络。基本流程：main()->osal_init_system()->osalInitTasks()->ZDApp_Init()，进协议栈初始化函数ZDApp_Init()。1.1进入程序入口main()。ZMain.c中C++Codeintmain(void){//Turnoffinterruptsosal_int_disable(INTS_ALL);//InitializationforboardrelatedstuffsuchasLEDsHAL_BOARD_INIT();//Makesuresupplyvoltageishighenoughtorunzmain_vdd_check();//InitializeboardI/OInitBoard(OB_COLD);//InitialzeHALdriversHalDriverInit();//InitializeNVSystemosal_nv_init(NULL);//InitializetheMACZMacInit();//Determinetheextendedaddresszmain_ext_addr();//InitializebasicNVitemszgInit();#ifndefNONWK//SincetheAFisn'tatask,callit'sinitializationroutineafInit();#endif//Initializetheoperatingsystemosal_init_system();//Allowinterruptsosal_int_enable(INTS_ALL);//FinalboardinitializationInitBoard(OB_READY);//Displayinformationaboutthisdevicezmain_dev_info();/*DisplaythedeviceinfoontheLCD*/#ifdefLCD_SUPPORTEDzmain_lcd_init();#endif#ifdefWDT_IN_PM1/*IfWDTisused,thisisagoodplacetoenableit.*/WatchDogEnable(WDTIMX);#endifosal_start_system();//NoReturnfromherereturn0;//Shouldn'tgethere.}//main()1.2给任务添加IDsapi.c中C++CodevoidosalInitTasks(void)//为各自进程添加ID用于任务的查找{uint8taskID=0;tasksEvents=(uint16*)osal_mem_alloc(sizeof(uint16)*tasksCnt);osal_memset(tasksEvents,0,(sizeof(uint16)*tasksCnt));macTaskInit(taskID++);nwk_init(taskID++);Hal_Init(taskID++);//硬件抽象层初始化#ifdefined(MT_TASK)MT_TaskInit(taskID++);#endifAPS_Init(taskID++);ZDApp_Init(taskID++);//判断如果协调器节点建立网络、如果终端节点加入网络SAPI_Init(taskID);}1.3初始化ZigBee协议栈网络ZDApp.cC++CodevoidZDApp_Init(uint8task_id){//SavethetaskIDZDAppTaskID=task_id;//InitializetheZDOglobaldeviceshortaddressstorageZDAppNwkAddr.addrMode=Addr16Bit;ZDAppNwkAddr.addr.shortAddr=INVALID_NODE_ADDR;(void)NLME_GetExtAddr();//LoadthesaveExtAddrpointer.//Checkformanual"HoldAutoStart"//检测到有手工设置HAL_KEY_SW_1则会设置devState=DEV_HOLD,从而避开网络初始化ZDAppCheckForHoldKey();//InitializeZDOitemsandsetupthedevice-typeofdevicetocreate.ZDO_Init();//通过判断预编译来开启一些函数功能//RegistertheendpointdescriptionwiththeAF//Thistaskdoesn'thaveaSimpledescription,butwestillneed//toregistertheendpoint.afRegister((endPointDesc_t*)&ZDApp_epDesc);#ifdefined(ZDO_USERDESC_RESPONSE)ZDApp_InitUserDesc();#endif//ZDO_USERDESC_RESPONSE//Startthedevice?if(devState!=DEV_HOLD){ZDOInitDevice(0);}else{//BlinkLEDtoindicateHOLD_STARTHalLedBlink(HAL_LED_4,0,50,500);}ZDApp_RegisterCBs();}/*ZDApp_Init()*/如果设置devState为DEV_HOLD，则不会执行ZDOInitDevice；反之，系统会调用此函数是设备组网或者入网。看下这个函数完成的功能是什么样子的。ZDOInitDevice是设备在网络中启动。它会读取NV中的ZCD_NV_STARTUP_OPTION选项决定是否恢复网络状态。如果应用层强制进行新的join操作，它应该在调用这个函数之前设置ZCD_NV_STARTUP_OPTION中的ZCD_STARTOPT_DEFAULT_NETWORK_STATE位。可以调用zgWrieStartupOptions()函数完成这些设置。1.4初始化设备（启动网络和设置网络类型）ZDApp.cC++Codeuint8ZDOInitDevice(uint16startDelay){uint8networkStateNV=ZDO_INITDEV_NEW_NETWORK_STATE;uint16extendedDelay=0;if(devState==DEV_HOLD){//InitializetheRAMitemstable,incaseanNVitemhasbeenupdated.zgInitItems(FALSE);}ZDConfig_InitDescriptors();//devtag.071807.todo-fixthistemporarysolution_NIB.CapabilityInfo=ZDO_Config_Node_Descriptor.CapabilityFlags;...
