POWER_SAVING有關(guān)的函數(shù) 1、 osal.c 中 osal_start_system()----> osal_pwrmgr_powerconserve(); void osal_pwrmgr_powerconserve( void )
{
uint16 next;
halIntState_t intState; // Should we even look into power conservation
if ( pwrmgr_attribute.pwrmgr_device != PWRMGR_ALWAYS_ON )

}
else

}
HAL_SLEEP_TIMER_CLEAR_INT();//清除中斷標(biāo)志
HAL_SLEEP_TIMER_ENABLE_INT();//啟動(dòng)定時(shí)器
} #ifdef HAL_SLEEP_DEBUG_LED

}
} 2、osal_pwrmg.c 中 osal_pwrmgr_powerconserve() 3、osal_timer.c 中 osal_adjust_timers(),osal_next_timeout 4、hal_mcu.h 中 #ifdef POWER_SAVING #define CLEAR_SLEEP_MODE() st(SLEEPCMD &= ~PMODE;)
#else
#define CLEAR_SLEEP_MODE()
#endif 5、hal_driver.c中 Hal_ProcessEvent（）函數(shù)中 只對(duì)系統(tǒng)消息事件，按鍵，睡眠定時(shí)器事件進(jìn)行處理 uint16 Hal_ProcessEvent( uint8 task_id, uint16 events )
{
uint8 *msgPtr;

msgPtr = osal_msg_receive(Hal_TaskID); while (msgPtr)
{ osal_msg_deallocate( msgPtr );
msgPtr = osal_msg_receive( Hal_TaskID );
}
return events ^ SYS_EVENT_MSG;
} if ( events & HAL_LED_BLINK_EVENT ) //燈事件
{
#if (defined (BLINK_LEDS)) && (HAL_LED == TRUE)
HalLedUpdate();
#endif
return events ^ HAL_LED_BLINK_EVENT;
} if (events & HAL_KEY_EVENT) //處理按鍵事件
{ #if (defined HAL_KEY) && (HAL_KEY == TRUE)
HalKeyPoll(); if (!Hal_KeyIntEnable)
{
osal_start_timerEx( Hal_TaskID, HAL_KEY_EVENT, 100);
}
#endif // HAL_KEY return events ^ HAL_KEY_EVENT;
} #ifdef POWER_SAVING
if ( events & HAL_SLEEP_TIMER_EVENT ) //該部分處理睡眠定時(shí)器事件
{
halRestoreSleepLevel();//為空函數(shù) return events ^ HAL_SLEEP_TIMER_EVENT;
}
#endif
return 0; } 6、ZDApp.c 中 ZDApp_DeviceAuthEvt（）函數(shù) #if defined ( POWER_SAVING )
osal_pwrmgr_device( PWRMGR_BATTERY );
#endif ZDApp_ProcessNetworkJoin（）函數(shù)中 #if defined ( POWER_SAVING )
osal_pwrmgr_device( PWRMGR_BATTERY );
#endif void osal_pwrmgr_device( uint8 pwrmgr_device )
{
//PWRMGR_BATTERY 低功耗，PWRMGR_ALWAYS_ON正常工作模式 pwrmgr_attribute.pwrmgr_device = pwrmgr_device; }
