  Hi Member

  I'm trying to caclute number of clock for this example caculate, the delay for the ' ' «for loops with 1000 run»»»

  

  After complition process the vi was executed on fpga and read the number of cycles in the pc with the real time and the number of clock was 5002 clock as shown below

  What is c?

  -----------------------------------------------

  I'm sorry for the stupid question, but my work on the architecture of the systems so these parameters is crucial and important for me.

  I left my old job on tool company xilinx ISE because the design of the system to take a lot of time so I now moved into labview fpga, its amazing especially in the optimization process, but the clock Concept here is very weak and totally confused.

  It's a different clock concept that most use of FPGA designers, it's true (I am trying to learn about it at the moment I'm doing some work software - C, not LabVIEW - on a processor clocked inside an Altera FPGA). For a normal programmer it makes sense - it works just like it does on a desktop computer. On a desktop computer you do not need to know how fast the processor is, you just need to know how long it takes your code to run.

  I don't know what is the distinction between the loop and frequency of system for you. There could be other components of the system that are running at a different frequency that you don't see, but are required by the LabVIEW environment (for the acquisition of data or communication with the host processor), but your code inside the loop runs at the level of the loop which can be measured with the number of cycles.

• want 5643 keeps returning to the main menu

  I just took the HP Envy 5643. I like a lot of things for the Black Friday price I paid. However, when you try to navigate the on-screen menu, she wants to keep jumping to the home screen, as if I had pushed the home button. Y at - it a setting or firmware update which corrects this, or is it a touchscreen flaky?

  Thank you!

  OK, I'm THAT guy. After trying everything under the Sun, I have it turned off and unplugged for a few seconds. What you know... problem solved.

• Example: Want 4500: I have Windows 10. On hp 4500 want I don't want to "print to PDF" as default. How to disable or change

  I have Windows 10. On envy, hp 4500, connected by a USB cable for my CPU, I don't want to "print to PDF" as default. How can I disable or change. Print only word documents and it is difficult to do not forget to change to print to PDF. Please if you can help me. I'm not savvy in computer science. Thank you!

  It seems that failed to print to PDF prints are a problem for other institutions. Looks like you can change a setting in printers and Scanners which determines whether Windows manages your default printer or not. Based on this image, I found that the option below is the list of available printers:

  I found this and more information here: Windows 10 Tip: disable default printer automatic management.

  Please let me know if that solves the problem or not. As previously mentioned, I will continue happily help if necessary.

• Example: Want 5532: print photos with red stripes through them

  I have a printer Envy 5532. If I print from an sd picture card print ok, copy a photo directly from the scanner prints perfectly, but if I print photos already stored on my computer they thin red lines randomly through them.

  Hello

  Thank you for your response. Now, I found that my problem was actually confused by a number of coincidences.

  I install the printer and run test print page & copied from the scanner and printing from an sd card until the problem of the "band" appeared. When I tried to print from a photo already stored on the computer, it was when he showed first really upward. I ran the Print Tool of doctor and no problems have been reported. Similarly, the printed test page seemed ok even though of course only small colored sections there. Finally, after running test after test, the ink ran out and I had to put in a new cartridge - Eureka! problem disappeared.

  I find, therefore, that I had a faulty cartridge that was causing the problem. I have since run a photo on the 'best quality' on Photo paper and it looks perfect. The high price of the cartridges, it was a costly exercise, but at least I'm now able to print my photos which is what I bought it for.

  Lagartija.

• 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!

• Delay the time of flat sequence Structure?

  How to delay the moment of execution for flat sequence Structure?

  Your question is a little vague.

  You want to delay in a certain amount of time? Until something happens?

  You can add a primitive frame with a wait.

  It might be useful to you could reach a simplified example so that we can better see what you're doing.

• Simulate a delayed signal

  Hello everyone.

  I have this problem: I do a simulation of the propagation of the signal between a Tx and a Rx, but I need to simulate the delay between the two points. The signal I want to delay is QPSK modulated with the modulation toolkit. The point is to show the original signal from T0 = 0 s, including the delay (same signal but with T0 = delay time in seconds any value).

  Thank you

  David

  That tal Falastiny,

  Sin problema pudieras explicarme the situation in Español adelante, como primer idea if you any that generated UN arreglo N elementos con valor 0, mediante the Relación of how many elements present UN segundo, there an este arreglo al final signal that estas simulando agregues para despues visualizarla en the grafica. Te recommend revisar functions to build array y dandole language the CONCATENATE entered opcioon selecciones.

• signal delay

  Hello

  My goal is to simulate a pulse generator, and I have some problems with double pulses. (see first attachment)

  I want to delay a signal from simulation, and I need to set this delay.

  At the beginning, I try with the Y [i] = X [n - i] VI.vi and the work but it is impossible to resolve in time.

  So I downloaded the tools of simulation of control and I try to use the simex transport delay.vi it looks like very good, but I can't import it into my project even if I try to turn it into a Subvi. (see second attachment)

  If you have another idea, I'll be happy to see.

  Could you help me please?

  If your deadline is in fractions of samples, no problem

  If this isn't the case, you can do it with a filter.

  Here's a program simple echo using convolution (also in fractional sampling rate)

• A message with a delay

  I want to display a message like after every one hour. I thought to use while loop with delay. But I don't want a delay when the message appears for the first time. I want a time gap essentially before the message appears again.

  Use one another while loop with a structure of the event. Put timeout in a registry to offset initialized to zero (so it immediately triggers the event timeout) and connect to Terminal timeout. On the right, thread 1 hour (in ms) to the shift register. Now, it will take an hour for the timeout to occur next.

  (Also add an event to the button stop to this parallel loop will terminate if the program is stopped.)

• Delay the start of an application

  I have a request for automatic enforcement, I want to delay the star of this application.

  Here's a suggestion:

  When your application first starts, call scheduleApplication to start your application at some point in the future, and then store a value (such as restart = true) in the PersistentStore (to prevent you from doing this twice).

  ApplicationDescriptor thisApp = ApplicationDescriptor.currentApplicationDescriptor ();
  ApplicationManager.getApplicationManager (.scheduleApplication) (thisApp, System.currentTimeMillis () + 60100, true);

  On the second startup, remove the persistent store value and allow the application to run.

• How to delay an event?

  Hello world. I want to delay an event a few minutes or seconds to not interfere with another event. How can I dow it? Thanks in advance.

  Concerning

  then you try NOT to delay an event that they prepare.

  You can simply use the timer to delay the call to a function that does something with "... another Clip with another sound '."

  var t:Timer = new Timer (5000,1);

  t.addEventListener (TimerEvent.TIMER, f2);

  function f1 (): void {}

  addChild (mc1);

  t.Start ();

  }

  function f2(e:TimerEvent):void {}

  addChild (mc2);

  }

• Where to put the delay to show/hide code?

  Hi all.

  How can we?

  I have an item I want to delay when masking, I found a few

  things about that though, I'm having trouble finding where to put the code?

  Here is the script below without the delay. Where I would put the delay code?

  Everything I have tried does not work. He always "presents" the item but without any delay.

  sym.getComposition () .getStage ().getSymbol("Console_Content").getSymbol("console_text"). $("cons_select_text") () .show;

  Any help would be great!

  Thank you

  Hello

  This code does not work: sym.getComposition () .getStage ().getSymbol("Console_Content").getSymbol("console_text"). $("cons_select_text") .delay (1500) .show (1);

  You can use setTimeout or setInterval: Object Window

  delay() function {sym.getComposition () .getStage (.getSymbol("Console_Content")..getSymbol("console_text") $("cons_select_text")) .show ();}

  setTimeout (delay, 1500);

• How can I delay the audio once a user clicks on?

  I have a click box and when the user click on I want to hear a sound signal, but not now, I want to delay for a second or two (simulate something sweeping). Is this possible?

  I think remember me Captivate used to remove the silence added at the beginning of a file. (I guess it still does?) I think that the workaround is to insert is not not-very-silence. So if you had a clip of storytelling, you would have to copy and paste a bit where the person was not talking but there was the imperceptible background noise.

  Y at - it a little the file, you can use the same way? (Or you have other audio editing software?)
