zigbeeCC2530休眠问题

请问，我启用休眠模式，本意想用定时唤醒，5S唤醒一次，当我设置终端的LED亮时，是闪烁的状态，并且闪烁频率很高，我找资料说是闪烁频率高说明一直有让CPU工作，理论上应该是没有的，请问我该怎么查找究竟是哪些任务在执行？另外，休眠的时候我是否可以不改变IO状态？谢谢

查找究竟是哪些任务在执行？

设置不同的标志或者输出调试信息才知道的。

休眠的时候我是否可以不改变IO状态？

看看数据手册上休眠模式的描述是否支持呢？

如果使用的是zigbee协议的话.可以一步步调试看看

1. 从osal_run_system 看是否能进入osal_pwrmgr_powerconserve(), 如不行要分析还有什么一直在run的task

2. 确认是否会调用如下的OSAL_SET_CPU_INTO_SLEEP()

void osal_pwrmgr_powerconserve( void ){ uint32 next; halIntState_t intState;

// Should we even look into power conservation if ( pwrmgr_attribute.pwrmgr_device != PWRMGR_ALWAYS_ON ) { // Are all tasks in agreement to conserve if ( pwrmgr_attribute.pwrmgr_task_state == 0 ) { // Hold off interrupts. HAL_ENTER_CRITICAL_SECTION( intState );

// Get next time-out next = osal_next_timeout();

// Re-enable interrupts. HAL_EXIT_CRITICAL_SECTION( intState );

// Put the processor into sleep mode OSAL_SET_CPU_INTO_SLEEP( next ); } }}

3. 再一步步debug ,hal_sleep函数,最终是否能执行到HAL_SLEEP_SET_POWER_MODE();

void halSleep( uint32 osal_timeout ){ uint32 timeout; uint32 macTimeout = 0;

/* get next OSAL timer expiration converted to 320 usec units */ timeout = HAL_SLEEP_MS_TO_320US(osal_timeout); if (timeout == 0) { timeout = MAC_PwrNextTimeout(); } else { /* get next MAC timer expiration */ macTimeout = MAC_PwrNextTimeout();

/* get lesser of two timeouts */ if ((macTimeout != 0) && (macTimeout < timeout)) { timeout = macTimeout; } }

/* HAL_SLEEP_PM2 is entered only if the timeout is zero and * the device is a stimulated device. */ halPwrMgtMode = (timeout == 0) ? HAL_SLEEP_DEEP : HAL_SLEEP_TIMER;

/* DEEP sleep can only be entered when zgPollRate == 0. * This is to eliminate any possibility of entering PM3 between * two network timers. */#if ZG_BUILD_ENDDEVICE_TYPE && 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)) || (timeout == 0))#endif { halIntState_t ien0, ien1, ien2;

HAL_ASSERT(HAL_INTERRUPTS_ARE_ENABLED()); HAL_DISABLE_INTERRUPTS();

/* always use "deep sleep" to turn off radio VREG on CC2530 */ if (halSleepPconValue != 0 && MAC_PwrOffReq(MAC_PWR_SLEEP_DEEP) == MAC_SUCCESS) { /* The PCON value is not zero. There is no interrupt overriding the * sleep decision. Also, the radio granted the sleep request. */

/* set CC2530 power mode, interrupt is disabled after this function * Note that an ISR (that could wake up from power mode) which runs * between the previous instruction enabling interrupts and before * power mode is set would switch the halSleepPconValue so that * power mode shall not be entered in such a case. */ HAL_SLEEP_SET_POWER_MODE(); /* the interrupt is disabled – see halSetSleepMode() */ /* restore interrupt enable registers */ HAL_SLEEP_IE_RESTORE(ien0, ien1, ien2);

#if ((defined HAL_KEY) && (HAL_KEY == TRUE)) /* handle peripherals */ if(HalKeyExitSleep()) { break; }#endif

} while(timeout != 0);

/* power on the MAC; blocks until completion */ MAC_PwrOnReq();

HAL_ENABLE_INTERRUPTS();

/* For CC2530, T2 interrupt won抰 be generated when the current count is greater than * the comparator. The interrupt is only generated when the current count is equal to * the comparator.

 您好：

我在这里有如下疑问：如果mac层没有关于定时器的事件，只有应用层有定时器事件，获取的最小溢出时间大于睡眠定时器的最大

溢出周期，此处会进行轮询，则到时间为0？轮询每次减去的时间为什么是HAL_SLEEP_MS_TO_320US( MAX_SLEEP_TIME )
