(1)ZDApp_Init() **************************************** void ZDApp_Init( byte task_id ) { uint8 capabilities; // Save the task ID ZDAppTaskID = task_id; // Initialize the ZDO global device short address storage = Addr16Bit; = INVALID_NODE_ADDR; //0xFFFE (void)NLME_GetExtAddr(); // Load the saveExtAddr pointer. // Check for manual"Hold Auto Start" // 检测到有手动设置 SW_1 则会设置 devState = DEV_HOLD, 从而避开网络初始化 ZDAppCheckForHoldKey(); // Initialize ZDO items and setup the device - type of device to create. ZDO_Init(); // 通过预编译来初始化一些功能函数. // Register the endpoint description with the AF // This task doesn't have a Simple description, but we still need // to register the endpoint. afRegister( (endPointDesc_t *)&ZDApp_epDesc ); #if defined( ZDO_USERDESC_RESPONSE ) ZDApp_InitUserDesc(); #endif // ZDO_USERDESC_RESPONSE // set broadcast address mask to support broadcast filtering NLME_GetRequest(nwkCapabilityInfo, 0, &capabilities); NLME_SetBroadcastFilter( capabilities ); // Start the device? if( devState != DEV_HOLD ){ ZDOInitDevice( 0 ); } /*如果 devState=DEV_HOLD, 则不会调用 ZDOInitDevice() 闪烁指示这是一个非自动启动模式,等待应用程序来开启是网络设备*/ else { // Blink LED to indicate HOLD_START HalLedBlink ( HAL_LED_4, 0, 50, 500 ); } ZDApp_RegisterCBs(); } **************************************** 这里说明三个函数: ZDAppCheckForHoldKey() ZDO_Init() ZDOInitDevice( 0) (1)ZDAppCheckForHoldKey() ************************** void ZDAppCheckForHoldKey( void ) { #if (defined HAL_KEY) && (HAL_KEY == TRUE) //个人认为:可以直接通过读取按键来看是否需要采用 HOLD_START 模式//如果发现 SW_1 按下(普通按键吧)/向上(Joystick up), 则设置 DEV_HOLD; // Get Keypad directly to see ifa HOLD_START is needed. // Hold down the SW_BYPASS_START key (see ) // while booting to avoid starting up the device. if( HalKeyRead () == SW_BYPASS_START) //HAL_KEY_SW_1 { // Change the device state to HOLD
