zigbeeCC2530休眠问题

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;

 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 )
