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 )
{
if ( pwrmgr_attribute.pwrmgr_task_state == 0 ) // 所有的任務都支持低功耗
{
HAL_ENTER_CRITICAL_SECTION( intState ); // Hold off interrupts. next = osal_next_timeout(); // 得到下一次的睡眠時間
HAL_EXIT_CRITICAL_SECTION( intState ); // Re-enable interrupts. // 進入睡眠模式 OSAL_SET_CPU_INTO_SLEEP( next ); //halsleep(next);
}
}
} //================================================================== void halSleep( uint16 osal_timeout )
{
uint32 timeout;
uint32 macTimeout = 0; halAccumulatedSleepTime = 0;
timeout = HAL_SLEEP_MS_TO_320US(osal_timeout);
if (timeout == 0)
{
timeout = MAC_PwrNextTimeout();
}
else
{
macTimeout = MAC_PwrNextTimeout();
if ((macTimeout != 0) && (macTimeout < timeout))
{
timeout = macTimeout;
}
} //如果timeout =0 進入深度睡眠，否則進入淺睡眠 halPwrMgtMode = (timeout == 0) ? HAL_SLEEP_DEEP : HAL_SLEEP_TIMER; //深度睡眠只有在zgPollRate == 0才會產(chǎn)生，這樣是為了盡可能的減少進入深度睡眠的次數(shù)
#if !defined (RTR_NWK) && defined (NWK_AUTO_POLL)
if ((timeout > HAL_SLEEP_MS_TO_320US(PM_MIN_SLEEP_TIME)) ||
(timeout == 0 && zgPollRate == 0))
#else
if ((timeout > HAL_SLEEP_MS_TO_320US(PM_MIN_SLEEP_TIME)) ||

#endif
{
halIntState_t ien0, ien1, ien2;
HAL_ASSERT(HAL_INTERRUPTS_ARE_ENABLED());
HAL_DISABLE_INTERRUPTS(); //關(guān)閉MAC和無線電全部電源
if (MAC_PwrOffReq(MAC_PWR_SLEEP_DEEP) == MAC_SUCCESS) {
while ( (HAL_SLEEP_MS_TO_320US(halAccumulatedSleepTime) < timeout) || (timeout == 0) )
{
//關(guān)閉外設，進入睡眠，此處函數(shù)為空
HalKeyEnterSleep(); #ifdef HAL_SLEEP_DEBUG_LED

#endif //啟動睡眠定時器中斷
if (timeout != 0)
{
if (timeout > HAL_SLEEP_MS_TO_320US( MAX_SLEEP_TIME ))
{
timeout -= HAL_SLEEP_MS_TO_320US( MAX_SLEEP_TIME );
halSleepSetTimer(HAL_SLEEP_MS_TO_320US( MAX_SLEEP_TIME ));
}
else
{
halSleepSetTimer(timeout); //設置睡眠定時器時間
}
HAL_SLEEP_TIMER_CLEAR_INT();//清除中斷標志
HAL_SLEEP_TIMER_ENABLE_INT();//啟動定時器
} #ifdef HAL_SLEEP_DEBUG_LED
if (halPwrMgtMode == CC2530_PM1)
{
HAL_TURN_ON_LED1();
}
else
{
HAL_TURN_OFF_LED1();
}
#endif
HAL_SLEEP_IE_BACKUP_AND_DISABLE(ien0, ien1, ien2);

} #ifdef HAL_SLEEP_DEBUG_LED
HAL_TURN_ON_LED3();
#else
HalLedExitSleep();
#endif //如果有按鍵按下，跳出睡眠模式，使能所有中斷 if ( HalKeyExitSleep() )
{

}
if ( timeout == 0 ) break;
}//end while //while ( (HAL_SLEEP_MS_TO_320US(halAccumulatedSleepTime) < timeout) || (timeout == 0) )

}
} 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 只對系統(tǒng)消息事件，按鍵，睡眠定時器事件進行處理 uint16 Hal_ProcessEvent( uint8 task_id, uint16 events )
{
uint8 *msgPtr;
(void)task_id; // Intentionally unreferenced parameter if ( events & SYS_EVENT_MSG ) //系統(tǒng)消息事件 {
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; }
