How to avoid overflowing number of cycles?

Hello.

I was warned for a long time on the use of number of cycles as basis for some time structure timeout, because the number of cycles is beyond every 49 days or more.  Since then, I had a bad taste in my mouth about its use, and I wonder what I can do about it.  I tried a bit with the comparison of the value of the number of cycles with the time and subtracting the value of timeout to the value of the number of cycles if this would cause a number of cycles to overflow.  But the code happens to be more than a bit messy and not very flexible.  Just see the attached VI.  Does anyone have a good solution on how to get around this problem?

I found this blog post from a guy who has made a conversion from 32 to 64 bit VI, and it seems to be just to the top of my ally.  But I was not able to reproduce because I recognize not all symbols (especially the small round one connected to the structure of matter at the far left).

This wanring should be interpreted such that you should not expect the value to be always on the rise.

The difference between the two ms tick counties will work even during the maxi over because this is how the calculation works for a U32. So if you subtract the beginning of the current, you can always compare the difference with the other to check if a certain amout of time spent.

  • How to control the number of cycles?

    I am a new user and I would like to ask a question. I use this VI (which is attached) and I want to control the number of cycles of the generated wave (sine, Triangle, saw tooth place).

    How can I change the VI to do this?

    Best regards

    Hi FaisalF,

    Looks like you're more interested in the output of a finite number of data. There is one VI example comes with LabVIEW that has this feature called tension - finished Output.vi. Then, you just create an array that will hold your 600 samples for 3 cycles of a wave of 5 Hz and entry of this table to the write function DAQmx in this VI.

  • How to control the number of cycles in the shape of triangle

    Hello

    I'm quite new Labview programming and find a hard time to code a simple program. If anyone can help me find a way to control the no. cycles of a triangle pattern.ie, if a key is pressed the code should send an individual right. wave form when it is in place the button should switch to its original state. I enclose the code that I've used to working on. The material used are NI 6013 and NI6723, as well as two BNC-2110 as input and output.

    Thank you best regards &,.

    Hello

    first of all, if you want to have an application like this, a simple while loop will not suffice. You will need to use a state machine or producer-consumer model. You read about them here, you have also some models and examples in LabVIEW.

    Another thing is that the production finished, it would be preferable to use the sample mode "Finished samples" (in the DAQmx Timing.vi configuration).

  • How to manage the turnover in number of cycles of FPGA output?

    I wrote a little VI that counts ticks on a set of lines of DI for a period of time. It uses the number of cycles of VI to determine how much time has passed since he started running. The output of this VI is a U32, and subtraction function looks like it going to saturate to '0' if the number of cycles longer rolls. How can I handle this situation to prevent the VI to leave earlier?

    Integer arithmetic must manage calculation rolling correctly (for example if your value is a U8 and you do 3-250, you should get 9). I guess (although I never checked) it works even in the FPGA. You can do a simple check yourself with explicit code. It would be nothing less than a complete cycle of safe, so it depends how much time it takes. If it is ms, it would take about 50 days. In your case, it seems that you have configured the service to be in us, so it would be somewhere more than an hour. If that's not enough, then you can maintain the real value in a U64 and then take the number of us that passing in each iteration and that adds to the U64.

  • How do you control the number of cycles showed on the chart

    How do you control the number of cycles showed on the chart?  I selected a graph of scanning, and I do not see the bar vertical chart when the program runs.  This is probably because I don't see the whole cycle of the periodic signal I try to display.  I need to set the graph to display several cycles.  Any help will be greatly appreciated.

  • Number of cycles in the target FPGA VI

    Hello to everyone.

    I'm working on a project where I use sb RIO 9636. I subtract a number of past and present of the encoder pulses. Here, I have attached VI that I use as target VI. When I use simulated I/O lets say that the program works correctly. When I compile VI on sbRIO I noticed that the LED indicator named x = y? never flashes (even if she flashes simulation).  Also, when I put indicaton on the number of cycles of control, counting starts from a few very very valuable.

    Could someone help me?

    Thanks in advance.

    Hi Chupka993,

    I suspect that part of the behavior of the that you describe, is that when you change the clock of the loop, you change the speed at which the loop works. As GerdW said, this loop timer setting gives your code a rate at which it should run. For example, defining 1ms means that your code inside this loop executes once per millisecond, or 1000 Hz. ticks would work similarly, but I think the timescale ticks of the FPGA clock which is generally 40 MHz on our devices.

    When you have the timer set to 1 millisecond loop, the code in the loop executes 1,000 times per second, and your iteration count would be 1000 times before update output, which means that your code runs a full 1000 iterations once per second. If you change the clock of the loop of 2 milliseconds, the loop will run 500 times a second sense that your 1000 iterations would take 2 seconds to run. I think that the behavior you're seeing is because the iterations are produce faster that you intend.

    You need to understand exactly how much time it should take your loop to run 1000 times and then set the timer loop to the appropriate value to achieve this goal.

  • Number of cycles Express VI outputs '0' on target with simulated FPGA of e/s

    When I set my target to "Run VI on it development with simulated i/o", the number of cycles to screw all the outputs ' 0 whenever they perform. How can I do a count up (in the case of "ticks") or a timestamp that is appropriate (in the case of "ms") the output?

    In fact it does not work as expected. I apologize. When in mode [ms] he ran if slowly as my test that bolt looked like they were defective and I did not notice the value incrmenting when I probed it. I changed the test to use the [ms] instance when running on the FPGA and the [ticks] instance during execution with simulated IO. This looks like it gives 1 tick every "" millisecond"simulated" when simulating and now operate my well tests.

    Thank you very much for the help. Sorry again for the false report.

  • Its mixed? While playing the slide with audio, if the customer has hit a tab with audio interaction, two sounds will play together. How to avoid what is happening?

    While playing the slide with audio, if the customer has hit a tab with audio interaction, two sounds play together, which is not a good customer experience.

    How to avoid what is happening? Placing a marker can help, but cannot solve the problem when the compliant/no intentional user, press tab.


    Better, if the presenter can triggle tab automatically at some point, or click interaction, no game bar function.

    Hi Louie,

    My sincere apologies for not being able to help on your previous question.

    Now, that the Interactions are concerned, they were initially designed to be placed as standalone content on the slide.

    Also if you try to resize your interaction and place it on the slide as well as other content/objects released published will always give a priority to the Interaction that it deemed to be a specific slide of Interaction.

    In the previous project, you shared, you try to time the Interaction with PowerPoint animations and wanted it to appear later on the set of slides, rather than on the start. But, as explained above, presenter honored not this setting in your project, because he in fact has considered a slide of interaction and display interaction since the beginning of the slide room itself.

    Also the number listed in this thread is concerned, there is no direct way to do it but I would like to suggest something that might help.

    If you want to keep the interaction on your slide and other content, Interaction will be available at the beginning of the slide. Surely there is no way that delaying his appearance, but you can still use animation related to Interaction in another goal. Within your presentation-> playback option settings, you can enable the feature of 'Pause after each animation' (see screenshot below). It will essentially help you achieve the function of auto-faisant a break from your animations, using your narration would automatically stop, just before you claim in your narrative and inform the learner to click on the different tabs of the Interaction. All you have to do is your narration and animation correctly so that the slide play does not break too many times in the time interval. Hope you find the idea of what I'm trying to say.

    Please mark this answer as being correct, if you find it useful. We would certainly look at such scenarios to be achievable directly at the request of our updates and later version.

    Thank you

    can someone help me pls

    Pavan

    There are two types of errors that I see. First, fix the date format before removing the slashes (because the source has no slash).

    D1: = to_date (SYDS, 'MMDDYYYY');
    D2: = to_date (SYDE, 'MMDDYYYY');

    Secondly, in the statement immediately execute you put in the text "d1" and "d2", not the values of d1 and d2. You must either concatenate the values like this:

    to_date('||) D1 |', "MM/DD/YYYY)

    Or better yet, use bind variables like this:

    to_date(:B1,''MM/DD/YYYY'')

    and add a "using" clause

    using d1, d2;

    I made the changes in the code. Try this:

    declare
      SMO  varchar2(100);
      SDO  varchar2(100);
      SYO  varchar2(100);
      SYDS varchar2(100);
      SYDE varchar2(100);
      a    varchar2(100);
      b    number;
      d1   date;
      d2   date;
    begin
      select to_char(sysdate, 'MM'),
             to_char(sysdate, 'DD'),
             to_char(sysdate, 'YYYY')
        into SMO, SDO, SYO
        from dual;
      SYDS := '0602' || SYO;
      SYDE := '0902' || SYO;
      d1   := to_date(SYDS, 'MMDDYYYY');
      d2   := to_date(SYDE, 'MMDDYYYY');
      execute immediate 'select to_char(DATE_OF_JOIN,''YY''),
                         COUNT(TOTAL_NO_STUDENTS)
                         from CROP_SALE
                         where class=7
                         and to_char(DATE_OF_JOIN,''YYYY'')=to_char(sysdate,''YYYY'')
                         and to_date(to_char(DATE_OF_JOIN),''MM/DD/YYYY'') > :B1
                         and to_date(DATE_OF_JOIN,''MM/DD/YYYY'') < :B2
                         group by to_char(DATE_OF_JOIN,''YY'')'
        into a, b
