TI BLE SensorTag中传感器事件是如何触发的?

Gary

哪位大侠能否告诉我TI  BLE SensorTag中传感器事件是如何触发的? 程序如下：uint16 SensorTag_ProcessEvent( uint8 task_id, uint16 events )
{
  VOID task_id; // OSAL required parameter that isn't used in this function
// events = events|ST_GYROSCOPE_SENSOR_EVT;   
  
  if ( events & SYS_EVENT_MSG )
  {
    uint8 *pMsg;
    if ( (pMsg = osal_msg_receive( sensorTag_TaskID )) != NULL )
    {
      sensorTag_ProcessOSALMsg( (osal_event_hdr_t *)pMsg );
      // Release the OSAL message
      VOID osal_msg_deallocate( pMsg );
    }
    // return unprocessed events
    return (events ^ SYS_EVENT_MSG);
  }
  // Handle system reset (long press on side key)
  if ( events & ST_SYS_RESET_EVT )
  {
    if (sysResetRequest)
    {
      HAL_SYSTEM_RESET();
    }
    return ( events ^ ST_SYS_RESET_EVT );
  }
  if ( events & ST_START_DEVICE_EVT )
  {
    // Start the Device
    VOID GAPRole_StartDevice( &sensorTag_PeripheralCBs );
    // Start Bond Manager
    VOID GAPBondMgr_Register( &sensorTag_BondMgrCBs );
    return ( events ^ ST_START_DEVICE_EVT );
  }

  //    Accelerometer     //
  if ( events & ST_ACCELEROMETER_SENSOR_EVT ) // ST_ACCELEROMETER_SENSOR_EVT  是如何触发的？是定时器还是profile callback 设置的？
  {
    if(accEnabled)

看着发帖出来好几天了没有回复，心中感到惆怅，这么多高手没有出手相救的，好在我早起晚归花了3天时间搞明白了，心中冒油样顺畅了很多，想要搞明白的事只要肯花功夫还是会收获的。
