• Real time counter?

  Is that after effects remove a real-time counter or a logo of a video network?

  Not automatically.  Your question tells me that you don't know much about After Effects. According to the shooting you can be able to clone a solution that seems normal, but most likely you will have to just cover with another graphic.

  Your question also makes me wonder if you push not copyright a little more.

  If you're new to AE so the option of replacement of cloning or background will probably take you a few days to learn how to do this successfully.

• How to create a time counter

  Hello expertsl,
  
  I have a new challenge on board.
  
  I have a form that is automatically popped up. Now on the form, I need to insert a timer as soon as it comes out, the timer starts and then I have to enter some data in the form and as soon as I press save button, the timer records the time count and then stores it in a table.
  
  Any suggestions are welcome...
  
  Thank you

  As Hoek said, this is not a forum of Forms .

  However, the problem is not really unique Forms and a timer itself is not necessary.

  A timer is a kernel object that fires at regular intervals each time around executes a callback routine. This allows to update or treat at specific intervals.

  You don't need a timer you are interested elapsed time - which means that on the creation of the form, you need to get the current time. When the user clicks the Save button you get again right now. The data you are interested in is the time difference between these two.

  Don't forget that timers are objects dear to create ito the kernel resources. Some operating systems limit the total number of timers that can be created. In general, it is not a good idea to create a timer unless it is the best technical solution to the problem. And you don't need a timer to determine a period of time. You just need the code in the constructor of the form and the code in the record of the events of the form. Nothing more.

• Timer counter to calculate the amount of liquid dosage

  I have a simple program of command VICI pump more interface series.

  The problem for me is that I need to see the amount of liquid dosed. I based it on 'elapsed time' express vi.

  But unfortunately it works the way I need. When I press the start of pump, it starts counting time and in a result of the liquid volume. When I press stop volume stops, but when I press Start pump once again as he continues the volume not the moment I stopped, but given the time elapsed since the first departure.

  I know that it is because the elapsed time is still running. I couldn't find a way to break it.

  Is there a way around it?

  I'm using LabView 8.6.

  Sergey,

  When you press Stop, the VI stops running. Are your referring to set up the Run on False switch?

  I put the volume (ml Injected?) on a register to shift and add the amount distributed to each iteration.  The calculation would be based time yet incremental time rather than total elapsed time.

  I don't think there is a direct way to interrupt the past Time.vi. You can store the difference between time and elapsed time in a shift register when you enter the mode pause and then use this difference as the new time target when you restart.

• Conversion of a relative time counter

  Hello!  I have a pretty simple question, if someone has a moment.  I have a while loop with a 1000ms wait inside, as well as some other stuff that is not relevant to the question.  Since my incrementer essentially account seconds due to the presence of the 1000ms wait, I would take the built in incrementer (i) and use it to display the relative time elapsed since the while loop began.  This loop will run for 3 hours, so I would like to display in hh: mmS format.  So basically, I'm looking for a way to convert the meter in a time value.  Any thoughts?  I know that the wait function is not exactly accurate, but that's ok.  I don't need to be 100% accurate in this vi.  Just a rough estimate will be fine. Looks like there should be a relatively simple way to do this, but I can't understand it...  Thank you!!

  Well, I just noticed a difference between 8.5 and 8.6. With 8.6, I put the relative time display format. Other that that, I don't know what would cause it to run backwards. Your postal code.

• WMP freezes, playback and time counter freeze and after a few seconds it will start from the point where it stopped.

  Original title: WMP 11 continues to stop audio playback

  I use WMP 11 for months with no reading problems but since yesterday evening he continues to stop for about 20 seconds every five minutes or so. When she did this, WMP freezes - meter reading and time to gel and I get the hourglass - and then after 20 seconds or more, the trail starts from where it stops. What is happening on all the tracks I did not play a single. I tried 20 audio files (mp3 all) through a dozen different albums. In addition, the gap between tracks seem longer than usual. I feel that it is looking for the data and playback stops because the time it takes to find the data is longer than the amount of data he has for playback? Either way, my files are stored on an external drive, and I'm now ask to update WMP for 'monitor folders' once again.

  I also downloaded a new copy of WMP 11 but this has not fixed the problem.

  I ran Fix It from Microsoft, but it has not to report any issue so I'm stumped. Any help appreciated thanks.

  Laptop Dell Inspiron 1300

  Thank you, Anoop - I notice that it is 7 - t - it too much work for XP? I'll take a look, although I found closure and restart toured (as far as the burning problem goes). Thanks for your help.

• timer counts down to the format hours: minutes: seconds: milliseconds

  Nice day

  Has had a problem with this kind of format treatment.

  And I want the milliseconds in 2 digits only.

  Any help is greatly appreciated.

  Here is my code:

  intervalID = setInterval(this,"timerFunction",1);

  function timerFunction() {}

  var msec:Number = getTimer();

  if (msec < = 0) {}

  play();

  return;

  }

  var sec: Number = Math.floor(msec / 1000);

  var min:Number = Math.floor(sec / 60);

  var time: Number = Math.floor(min / 60);

  if(sec<10) {}

  secStr = "0" + String (dry);

  } else {}

  s = secStr;

  }

  if(min<10) {}

  minStr = "0" + String (min);

  } else {}

  MINSTR = min;

  }

  if(hour<10) {}

  hourStr = "0" + String (hour);

  } else {}

  hourStr = time;

  }

  //trace ("min:" + min);

  //trace ("sec:"+ dry ");

  //trace ("ms:"+ msec ");

  _root.timerText = hourStr + ': ' + MINSTR + ":" + secStr + ":" + msec;

  }

  Display the result:

  00:00:01:1012

  00:00:02:2048

  You will not contravene all rules (don't know too many except those to be polite, etc.), but you neglected to say what to look for.  I finally found what I think you're talking about and what is displayed it is meaningless.  I think it's just a Visual prop because it seems never to go beyond 20 - something.  And that the way in which the time end up like the exact values, it is certainly rigged.

  As I said already 1000 msec = 1 sec, and you can get up to 99 with two digits, then you should think about what you want to do.

• How to count the time exactly?

  I tried to count the time using a VI like the one attached.

  It's that's not couting correctly. There is a possible reason, I have observed.

  The computer isn't able to handle the VI as soon as necessary.

  I thought about this because, when in edit mode the time count was very bad, and, when I created an application and installed, it ran okay, how 'light '. But today, when I tried to use this application with an old computer it did not work. The clock is slow.

  Is it possible to count the time correctly?

  I use a DAQ6009 to make my works, my VI is big enough and I need one iteration to each 1 ms (milliseconds) as I am with digital inputs from 5 events of coders (I know that's not the right way to count the encoders, but it's the only way I can do it, and it works).

  Thank you in advace! I hope you can help me!

  Hugs!

  Ok.  I will try to help you understand certain things.

  The number of cycles and wait (and wait until the next ms Multiple) functions all use a 1 kHz derived from the clock of the processor clock. The accuracy of these clocks is not large, although they are probably similar to the precision of the stopwatch.  Any time generated by these functions will show some differences in the time of the clock as it is derived from a different oscillator.

  Updates from the front panel are time by LabVIEW and the operating system. Most of the screens are updated with 60 to 80 times per second, maximum. What made the operating system, an update of the screen might be delayed by 10s of milliseconds or more.  It is certain that not all of the values at the end of the Add function will be displayed.

  Wait for him until the next ms many will wait more than 1 ms if the other code in the loop takes longer than 1 ms.  I don't know, but I think that the indicator is buffered so that any delay by the operating system to update the display should not slow down the loop. I tried to remove the flag, and it doesn't seem to make a big difference.

  I modified your VI to provide several indications of the performance. First of all, I added to the sequence of three-frame structure to allow synchronization of the loop. Second, I changed to a loop which runs a specified number of iterations. Thirdly, I hooked up the output of the timer until the next ms Multiple to a tunnel of autoindexing allowing a record of the time of each iteration appears in the table of ticks. I calculated the differences between successive instants and poster on a chart, so that you can see the performance.

  I didn't want to sound criticism of your use of English.  You write in English, much better than I could in your language!  What I was trying to make is that such general descriptions that ' Besides correctly ' without quantitative results or evidence in support of the application do not have enough information to help us help you.

• Redundant notifications watch OS 3 Countdown Timer

  Watch 3 OS, the countdown now redundant notifications. When the timer counts down to 0, you get the normal "meter made" alert and then 15 seconds later, you also get a notification of alarm named 'COUNT_DOWN_TIME_REACHED '. It doesn't seem to be a sign of timer settings in the application settings of the watch, so I can't understand how to disable this alert redundant and boring.

• cDAQ-9181 with NI 9402: after the first cycle of meter reading lack certain counts in all subsequent cycles.

  Hello

  I'm reading pulses TTL of a generator of service using a meter. I apply a 1 kHz signal to the meter. Each time counter reads the pulses correctly in the first cycle of measure, but it lacks some counts in all subsequent cycles.

  I use NEITHER 9181 cDAQ chassis and NI 9402 module with 2014 LabVIEW and NI Max 14.0.

  My computer has the Windows 8.1 operating system.

  Please find the VI joint and the front image after EXECUTION.

  I also used the same VI with chassis USB cDAQ-9171 . Results have been improved, but the same problem persists.

  What could be the reason for this, please guide.

  Thank you!

  B. Sharma

  1. the loop time is defined by software and therefore won't be compatible.

  2. you restart the meter patch between each iteration of loop - so that the task is restarted, it does not take samples.  The new start is faster on the USB device from the device ethernet due to the latency of the lower bus, so that explains why the behavior is improved on the 9171 compared to the 9181.

  Using method 2 meter would be a clever way (maybe too smart...) to implement which, according to me, you are looking:

  

  This will configure a second counter (ctr0 is paired with ctr1, ctr2 is paried with ctr3) to generate a signal of a period known (time measurement).  The meter is taken into account the number of external pulses during this period, and since we are because data in terms of 'Ticks', it will give you the number that occurred during the measurement time.  This measure is repeated for the specified number of Cycles without software-timing or latency between cycles.

  The appeal of reading will have a time-out value long enough to ensure that all cycles have completed (or you can query to see if the task is made first of all to give the user the option to cancel the measure).

• How to read a counter value for the separation of the two edge before meter is stopped by the second edge (6602 Council)?

  I use a timer/counter with DAQmx 6602. I use the separation of two - available via DAQmx cash edge. Count between the two edges works properly, however I do not know how to read the value of the counter during the counting operation (i.e. after the first edge triggered the beginning of the count, but before the second edge triggered the end of the counting). I'll have to wait for the second goes off the edge of the end of the countdown until I can get a counter value. I need to be able to access the current value of the County during the count operation. This was possible in traditional DAQ. How can it be accomplished using DAQmx?

  Ah shoot - I was afraid that this might be the case (for what it's worth, my series of X returned intermediate values, but the material and the underlying driver are quite different)...

  You just need to take one measure at a time or you are buffer several measures of separation of the two edges at the same time?  So just to take one measure at a time, you can set a task of edges of count using the database internal time as the source using an arm start trigger (first edge) and a sample of clock (second Board) to work around the problem.

• Outputs produced by the analog input job Retrig delay counter

  Hi all!

  First of all, I want to thank everyone on this forum who take the time to answer the questions, this forum has been invaluable to me.  I have a question about delays in adjustment to the pulse output of a counter, like what is described here.  My question is related to another, asked hereon the trigger of an analog signal and producing a pulse for each triggered event.  I have this job and can be seen in the attached vi.  Basically, now I'm able to produce a TTL pulse whenever my analog signal passes a predetermined threshold.  I have also documented the vi to my best understanding, if I have something wrong in the documentation, please let me know.

  In any case, now that I have a pulse at each outbreak, I would like to be able to adjust the delay of events so that the pulse is not produced until the period n/20 (n = 0, 1, 2,... (19) what I expect to see is a similar pulse train in 'fig. 2' in the article, where the white pulse is the counter pulse, and the pulse red would be the same as my analog signal.  So, for example, if I had a 281Hz signal, I want to produce a single pulse with a width defined by the user whenever my signal crosses a threshold (it's zero delay: 0/20); This part may be made using the vi attached to this subject.  Now I want to delay this impulse as to each trigger event, a pulse is not produced until 1/20 of the period, or 0,000178 seconds after the trigger.

  Looking at my vi, I think that if I change the output channel of the meter to 'CO Pulse Time' and then set the respective initial delay, time and little time, I can get delayed impulses mentioned in the article.  Correct me if I'm wrong, but I think that basically 'big time' controls the pulse width. 'initial period' is what controls how long to wait after the first trigger event is reached, before generating a pulse, but this applies only to the first impulse and not the rest; and finally 'small time' is the time to wait before the next pulse is created.

  Earlier today, when I use the CO Pulse Time option, it seemed to work properly for me to a certain degree.  At low frequencies the impulses seem to trigger to each event when the pulse width is set at 2.5% of the period.  When I tested at 281 Hz with a pulse width, 'big time' of 0,000089 sec and without anything wired for the 'initial delay' or 'small time', the impulses seem to ignore systematically each triggers 2... that tells me that something is wrong in my settings, rather than problems with the sample clock.  So I decided to connect '0' to 'small time', but then I got an error message indicating that some time may be less than a value (I forgot what the error message).  So I concluded that I must not understand what these terms mean.

  Sorry for the long explanation, but I really need help with this.  So let's say that the first set of data, I want to acquire is at zero delay, such as pulses are generated at each triggering event like how I have my VI now; so, for the next set of data I want pulses to generate 0,000178 seconds after the trigger threshold; so, for the data set third, I want to pulses to generate 0,000356 seconds after the trigger threshold; and so on... How should I do for this?  Thank you very much!

  Hello!

  Please post on the Forums OR! I think the main issue here is that you are sampling not fast enough to catch all of your high. So you set your high dry 0,000089. You will need to substantially increase the frequency of sampling in order to catch all these. Something around 25 k should do the trick.

  To the extent where using the time counter Pulse, you're totally on track. I think that the use that the delay will do the job.

  I hope this helps! Let me know!
