multiple inputs and nested loop problem

Hello world

I'm using Labview 2009.

I want to change the value of a variable by using the wheel or keyboard.

So I downloaded a button and the screws of the keyboard that suits my needs of multi-rotation forum.

These two screws are running inside a WHILE loop. Because I would be constantly updating the variable I will run my main screw that houses these two screws also looped a WHILE.

Problem is that while loop within a while loop I couldn't run my main VI because of this problem.

I tried in 2ways

1 including them as an auxiliary in my main VI but as the two screws screw contains a few other variables inside of the inside while loop that LabVIEW displays error as auxiliary screws will not work

2. I also tried to copy paste the two screws as it is in my main screw but could end up only in a lot of errors.

How to deal with this problem of nested while loops?

Please guide me.

Kind regards


You make a mistake of data flow. The outer loop can turn only if all of the code that he has completed. The structure of the event cannot complete because inside while loop has not finished, and if inside so that the loop ends, the loop cannot turn because the structure of the event stalls. You can only go to the next iteration after all both have completed, from the mess.

All you need to do to incorporate ALL the code inside the structure of the event. Attached, it's a simple project (LV 9.0), modify as necessary.

See if it makes sense for you. (there are a few minor bugs probably)

  • Variable and nested loops

    Hi, I'm a relatively new to programming of LV, so be gentle.

    In a Word, I am running nested loops than the material test power on and off cycles. The parameters for each loop is entered on the front panel of the user. For example, the power supply at the time, how many times to read in the data, power supply off time and the number of cycles power is a typical customer task ask me to do. Therefore, I decided to do a generic as possible executable vi instead of writing code (in which I request is trivial), that my technicians can easily use.

    I want to put a counter - down in this vi, even a journey of one. I'll take the more the off time multiplied by the number of cycles and display on the front panel. For some reason that I can't find a simple way such that when the last cycle ended if poster zero before the program ends.

    For example, the total is equal to 60 minutes and 10-minute cycle. I run the program and the display shows 60 during the first cycle, after the first cycle is complete and the second cycle begins the display turns 50, and so on until that last cycle where you can read 10. Then the program ends and the screen 10. How can I get a last beat of this kind it says 0 and 0 poster before the end of the program?

    Thank you!

    Wire a zero to a local variable of this indicator so that it can turn when the while loop ends.

  • Table and the loop problems (please help)

    Im making a site for a project where I have to include a table and a loop.

    For this section, I put in a "contact us / Q and A" page where the user can enter a name, email, and question.
    This information is sent to a table and then following image shows the form of the table information in the dynamic text boxes.

    I've included a loop to check that each part of the table contains data (name, email and the issue).
    Then I have an If Else, which clears the form either if a section has been missed, OR if the form was completely correctly it directs the user to the frame following where as I said above the details appear in dynamic text boxes.

    The problem im having is the loop to check For the table that's a waste. Someone can please help me out here and get the loop to verify that all fields have been filled.

    Here is my code for the initial frame

    You must update the values in your table at the time you press the submit button. Code follows

    There is a second example to check the strings (it's a little complicated, but it's a useful trick if you can understand). This does not leave the Send button work unless all fields have something in them

  • Roto brush (recommended for multiple cuts and also the problem of incompatibility frame)

    I have a dance video of 3 minutes with several cuts, views, and angles - and I want the piece to roto brush in After Effects. I'm trying to separate the dancer from the background. It would be wise to Roto Brush tool each Cup separately (in this case I would export each piece in a separate file in Final Cut Pro)? I guess Yes, but not quite sure.

    When I convert a publication to 59.94, 29.97 (because of the incompatibility of Frame error) I don't see that it really doesn't matter what... change t - it? Is that clear change only once fully made (RAM Preview)? Or is that what the roto Brush tool "smarter" - more capable?

    Thank you!

    Cut the shots. It's the only way.

    Doubling the frame rate is only an option if you have separated the fields on interlaced images. The difference is that you see all areas. I can't tell you if it's the right option without looking at the pictures. We must try and scroll one image at a time to see if you have duplicates. If you do, then this is an unnecessary step.

  • I use an analog input on a PCI-6224 and are having problems with the clock source

    I use an analog input on a PCI-6224 and are having problems with the clock source. I'm trying samples of 16 different analog inputs very quickly. I have the sample mode: Timed Single Point material. The rate, that I am running is the maximum (250 kHz (15625Hz per channel)). I left the default clock source and trying to taste several times. The analogue input works for a short time (2-3 seconds) and then everything stops. I'm doing something wrong or is there something I'm missing? Any advice would be great.

    That's how you samples using the sample clock clock. If you see a delay then something is wrong with how you track/data visualization.

    Single point NI the hardware is for PID control with a real-time operating system.

  • Digital input and output problem


    I do a test for digital i/o:
    for a table of the digital signal to an output of data acquisition in the digital input to detect the output signal.
    (bascially, it's like a loop that goes outside the material)

    It's pretty simple, as shown in the attached fichier_1.
    It works well.
    The manual light switch controls, which means that inputs and outputs are ok.

    Then I went on the low level DAQ for better speed, as in attached fichier_2.
    But it does not work. Especially when I pressed stop to abort the loop, an error has occurred:

    To speed up, I went to the low-level data acquisition as the fichier_2 attached.
    But it does not work. Espeically when I press the "stop"button to exit the loop, the error occurs.

    Possible reasons:

    Requested value is not supported for this property value.
    The value of the property may be invalid because it is in conflict with another property.

    Property: SampTimingType
    Asked the valuelarge clock
    You can select: on request

    I don't understand why the sampling time has a conflict here.
    (It is probably just something very simple in data acquisition, but I checked a few examples and did not find a clue).
    Hope someone can give me a suggestion.

    Ultimately, my goal is to make the attached file_3.
    In this one, I generate a digital output, and then lead to the entrance.
    Then I can take it as a signal to trigger my other task.


    I use a similar conti signal to control one of my camera.
    I need to sync it with my another task.
    So I think to generate a digital output (which share the same clock as the signal similar to the data acquisition device), then put it in one of the digital input.
    By detecting this digital input, I can trigger my task and synchronize with this signal similar.
    My camera's USB-6211.
    I am aware of the latency of USB, but once the value is a constant value, then the synchronization is always good for me.
    Actually, I was using an analogue at the entrance of the to do it before, it may work, but the synchronization error is too big for me.
    I need to do some calculations/judgment for this analog value, which makes the time difference varies.
    So I'm trying digital entry now and I hope that the digital input can trigger my task with a stable latency.

    Thank you very much

    Have you looked at the specs? It clearly states that the digital I/o is a programmed software. You have not any hardware clock at all. The best rate that you could possibly achieve is around 1 kHz and which would have a considerable jitter the nature of non-determimistic of windows.

  • Precise triggering voltage input and output generation in the DAQ Assistant


    I wonder if anyone has come across a simular problem with the synchronization of input and output voltage. I use a box 11 LabView and NI USB-6259. I have been using the DAQ Assistant to configure the input and output channel. In particular, my task is to generate a single rectangular "pulse" as the output voltage to drive a coil and once the pulse went to get a signal from a sensor of magnetic field and get a power spectrum. This means that the order and the time during which the DAQ Assistant is used is extremely important. For example, the output voltage channel must be opened first for 2 seconds. Subsequently, the channel of input voltage must be open for 1 second, in which the sensor signal is obtained and post-processed. Only after these tasks are performed in this order he can can be repeated in a loop until the experiment is over. I don't know how to trigger data acquisition assistants (one for entry) and the other for the voltage output correctly. Y at - it a trick?

    See you soon


    Hi Dave,.

    Thank you that I wired the error strings but the timing issue was unrelated to it. In the DAQ assistant, I simply had to choose the continuous aquistion of the 'samples' methods 'N-switch' for input and output voltage and all works fine now.

    Thanks again


  • Help to find the best way to interior design (Nested Loops of sliders?)

    Oracle 11G

    First here the table I work with, for example data

    11008755360FC1053, 81-82FC105381821
    21008755360XD, 3-24XD3242
    31008756293FC1053, 81-82FC105381821
    41008756293XD, 3-24XD3242

    Each FID is a different line, these two lines are connected physically, that's why I've shown them here on the table. Each line has a 'meter', in this case, each line has 2 lines of account that are the same.


    From there, we can say that FC1053, 81 and 82 are connected between the 2 cables. XD DESIGNATION means that cables are connect not really so I can't ignore those.

    We have a different way to show that they connect other than only those data and I need to connect each other too much. For this I need the Info


    So my first design was the hepatitis hase sliders 2 with the data in the table, as shown above. I would then have a nested loop. The first slider to select the first record, then go down to the second loop where I compare all other records the first record and then go back in the outer loop to move to the next record, then return once again to the inner loop to compare the values again.


    LOOP 2









    END IF;

    END IF;

    END IF;

    END IF;

    END IF;


    -Open and close done to reset the cursor to the front/top




    The problem with this approach is once the outside loop moves the next value of the IDF, that logic will connect them once again, but this time with the FIDs reverse which is essentially the same thing as it does not matter the direction in which they are connected. I almost feel that once I found the link I need to remove that line from the cursor (which isn't possible).


    I was able to

    1. make a list of all those I have connected and check against that

    2 use some kind of collection

    3. use a temporary table to hold the data

    4 something that I have not yet thought

    I really appreciate in advance for any help I get.

  • Partition pruning, nested loops


    I'm having a problem with obtaining the size of partition in a query. I managed to dumb down the problem to the two tables and a minimum query (see below).

    Basically I have a partitioned table "Made each year" and a table of assistance 'Current year' that contain always 1 row. The sole purpose of this line is to say which is the year curent, it was the previous year and that next year will be. (In the real problem, there is no standard timeperiods, so we can't calculate just previous and next by adding/subtraction 1 as would be possible in this example).

    The following query is executed as I want.
    It runs a scan on current_year and then nested loop on the facts. And the size of the partition that was happening.

    I think that the decision of condition influenced gold optimizer. You can rewrite your query to use UNION ALL to see if it helps.

    select sum(decode(year_key, curr_year, some_measure)) as curr_year_measure
          ,sum(decode(year_key, prev_year, some_measure)) as prev_year_measure
    from (select a.year_key, b.curr_year, some_measure
      from yearly_fact_t a
          ,current_year  b
     where a.year_key = b.curr_year
    select a.year_key, b.curr_year, some_measure

  • USB &amp; Firewire audio interface ports still work as input and output?

    I guess everyone has to start somewhere, even if it is borne by almost everyone I would like to know the answer to my questions, perhaps with good reason, what I don't know is so if the USB ports unique connection and firewire on an audio interface function ALWAYS both as input AND output.  In other words, whenever I read the information about the product on audio interfaces, no matter where I go, it is generally accepted that most people buy their audio interface for RECORDING.  And so when most people talk about connecting their Apple computer, iMac or MacBook Pro, it is generally accepted, they turn to the USB as INPUT.  That's all very well and good.  But in my case, I want to use the USB port as output (not the taken mini) and go into an audio interface that gives me as a symmetric output signal that I can plug my amplified studio monitor (which has only a balanced XLR input). All of the examples I see with audio interfaces address registration and involve the use of the USB on the audio input interface.

    So my question is: can one USB port I see on any number of audio interfaces always function both of the inputs and outputs? It takes, but if so, why does any site mention this fact and whey didn't they show in all the diagrams of the audio interface manual hook to studio monitors?  I know what may be obvious to some, but as a user with the intention not to use a piano for a scene while but rather a keyboard/MIDI controller that is attached to the iMac to be able to use the virtual instrument software, I need to go to the controller to the iMac, then the iMac in symmetrical powered monitors. Do the balanced inputs of speakers requires more than a simple adapter to give the President a balanced input.  But nobody talks about audio interfaces usually unless they talk about as a way into the computer to record.  As for my situation? Why don't they include this example?  And why should they assume that novice will automatically KNOW that the usb port, an audio interface will work as an output as if they never EVER mention this example or Setup?  I guess it is to operate in both directions!  But really, I'm crazy to wonder when no one never speaks or shows this configuration? He suggested I buy something similar to a UR22MkII of Steinberg, who has a USB port. Even the Steinberg site speaks only records and so using the USB key as input for use with the recording software. There is no mention of its use out the mac in balanced speaker entries, even in the manual. In fact, it is question is always true for every audio interface manual that I watched, even by other manufacturers! Why they all assume a novice like me (whose money is just as good as money from the experienced user) KNOW that? It's frustrating!

    I know that this is not strictly a matter of logic, but I guess, in my view correctly, that a logic user community could be more appropriate to address my question for others communities. If I'm wrong, please help to re-send-the matter.  Thank you.

    Sound the interface itself that determines it can send and receive Audio or Midi... not the USB or FW port which both are devices of e/s...

    All USB and Midi peripheral FW are inputs and outputs

    All the USB and Audio FW are inputs and outputs...

    All devices USB or external hardware with a USB port... can handle Midi and Audio...  Some do... Most manipulate just Midi... or just Audio

    The Steinberg UR22MkII manages Audio and Midi...

    However, I do not recommend USB 2.0 audio devices... There are simply too many cases, problems and questions after the major updates for OS X with such devices especially when they are class compliant (IE without driver), even if the UR22MkII Steinberg is supposed to be compatible 10.11...

    View the other may vary... because it's just a personal opinion based on my past experiences both in my studio... and based on the many issues presented here and elsewhere.

    I'm sticking with Motu equipment for all my Audio devices... and I use iConnect devices for my Midi needs...

  • Equium M50-244: loop problem internal ati2dvag.dll

    I had a M50-244 XP Home Edition (sp2) who have ATI onboard until I uninstalled it completely. The laptop has become totally useless vomit ati2dvag.dll inner loop problem and nothing seemed to heal so I decided to completely get rid of ATI.

    It started with VGASAVE which, with a few adjustments, work is fine and so my machine now. I disabled the video as controller he kept coming up with "new hardware found" and I didn't load the drivers more who would do what he started crashing again.

    Currently its on 'test' and I'm doing everything possible to see if it will crash once again, I hope not.

    Maybe I need another driver and activate the video controller, but I am hated for doing anything more now that his works normally, finally!

    Some said the installation of the graphics driver on the site and improves the performance of the graphics card.
    Maybe an installation of the driver from the site could be useful.
