Async timer and Mutex?

Similar Questions

• Async timer events

  I use CVI 2009 and TestStand 4.1.1 to test products.

  I create an Async timer when I call a function of Teststand that propelled to the top of the object to measure.

  My timer seems to start OK, but there are only 3 events prior to the recall of the timer Tick is no longer called.

  What could cause the timer events stop?

  Thank you

  1 take the timer.

  2, reminder timer is blocked or delayed and no return for timer events are queued up and not be served.

  3, an another async timer was created before the one you use for power USE up so this timer is a priority and is occupied by the management of reminders in your reminder of power queue USE is getting hungry.

  4 Async timer thread cannot get scheduled.

  Recently, I've solved a problem scheduling async timer using an indicator LED on my GUI and he put on during my async timer reminder entry and turned off when I left.  I made sure that he stayed at least 200 ms if I could see it.   Main thread set the light / stop by a global since you can not manipulate the UI directly from the asynchronous callback.

• behavior of stall Async timer

  At the service of my never-ending quest to understand async timers...

  I have an application with two asynchronous counters, each with its own recall, and I understand that both run on the same thread.

  So if one of the reminders of cale, will either never get planned?  If they really are on the same, single thread, so if you lock one two reminders (for example put it in an endless loop), then the callback else should never get called.

  Thank you.

  Has a handle on this at last.

  The problem was that only 15 sec timer takes 16 sec to complete the recall

  Since it was created first, and since it cannot follow it's own program, it works all the time and the 30 sec timer gets hungry

  What makes this difficult to analyze, it is that time within 15 sec timer reminder enough to 16 sec after that the timer of 30 seconds is a state change to the system.  So the problem in correlation with the behavior of the reminder 30 sec timer, but the main cause was the behaviour of the 15 sec timer callback.  Correlation is not causation, as they say.

  I've implemented a a LED on the GUI for each timer that gets set on when the timer reminder came and stopped when she leaves, and then I could see what was going on.

• No graduation async timer

  Hello.  I have a program that is running multiple threads.  When the user clicks the start test button, a new thread is created to run all data acquisition and task processing.  Part of the task of data acquisition is to acquire an analogue to the digital map data.  To start the acquisition, a function is called from the map SDK.  This allows relaxation on the Board with a callback that is called when the map is triggered.  I have included in my code, a timeout by using an asynchronous timer so that if a trigger is not received with a set amount of time, the acquisition is cancelled.  The problem I have is that no clock is received by the async timer.  The basic layout of the code is as follows:

  RET = dataAqFuncStart();

  If (ret = NO_ERROR)

  {

  SetanalogTrigTimoutFlag (TRIG_TIMEOUT_CLEAR);

  timerId = NewAsyncTimer (ANALOG_IN_TRIG_TIMEOUT, 1, 1,
  DaqAnalogInTimer, NULL);

  }

  If (ret = NO_ERROR)

  {

  While ((GetdaqAnalogInFlag() == 0) & GetanalogTrigTimoutFlag() == TRIG_TIMEOUT_CLEAR)

  {

  }

  }

  Within the callback function for the data acquisition card, the daqAnalogInFlag is set if the map is triggered.  In the async timer, analogTrigTimeoutFlag is set to graduation of timer.  I never really get a graduation of timer if so my code is in the while loop.  In the context of debugging, I was followed by system resources which showed that the two sons of my computer was working 100%.  I placed a delay of 200ms in the while loop and this has reduced the CPU activity of approximately 3/4.  I guess it's because the code was executed the while loop getting frantically two flags.  Another thing, I tried as part of debugging placed 'GetAsyncTimerAttribute (timerId, ASYNC_ATTR_TIMER_TIME & timerTime)' in the while loop after the deadline.  On the first time through the while loop, the value timerTime has been to 0,0.  On the second occasion, the time is 5006.598 which obviously incorrect as only about 200ms has passed.  The last observation was that there is a call of the event to the reminder timer when I close the thread that was created at the beginning of the test.  This indicates that the timer has been created.

  Are there other methods of debugging I can use or can someone point me in the direction of an answer?

  Thank you

  Do you really need a timer that is asynchronous to get the timeout? You could just check the value of the Timer (in the loop and exit) on a specified time? Is something like this:

  if (ret == NO_ERROR)
  {
      tini = Timer ();
      while ((GetdaqAnalogInFlag() == 0)  && (Timer () - tini < 1.0))
      {
         // Some code
      }
      // Cleanup code
  }
  

  Async timers are executed in their own separate thread: I don't know what can happen all by creating an asynchronous timer in one thread other than the main.

• Show only the time and a red relief

  My watch does not show the clock face. If I press the bottom button, it will display the time and a symbol of red light.

  Hello

  Your watch has a low battery charge level and entered into mode of power reserve.

  This mode displays only the time when you press the side button, in order to keep this service as long as possible.

  You will need to exit this mode, press and hold the side button. However, you need to charge your watch first. Allow up to 2.5 hours for a full charge.

  Phone bought 3 days ago and I fight to turn it on, it's just a black screen, the phone records into iTunes but does not turn, I tried holding down the home button and power at the same time and still nothing, I presume that it's a battery problem as if it was the backlight then the phone vibrated when you press the power button help Please!

  Put it on wait ten minutes if the phone did not come one, then hold down the sleep/Home button until you see the apple logo and then release, make sure that the phone is still connected to the charger.

• Time and Date setting

  In general - the time and date settings can I put two areas. I want to see two areas on my status bar. Don't want an app for that.

  I'm afraid, which is not supported by the firmware. If you want that for any update to update future iOS, let Apple know your wish using this link:

  If she needs your Apple ID password and you have enabled 2-factor authentication, you might have to temporarily disable the connection to complete.

  Also, you need an internet connection to perform this step here.
