• Leave a while loop

  Hello

  I have a while loop that I want to go out with a stop on the front panel.

  Here is a bit of code:

  

  As you can see the code in the while loop is processed by filling four sub .vi.

  I found that if I press the button to stop at one point, the computation of the 4 sub fired then the other while loop will pass and not out at the end of the calculation of the sub 4. screw.

  What is the way to get around this please? I realize that the help of the fixed stops on the front panel is not recommended!

  Thank you

• data without a loop

  I have a communication series VI to communiate with some radios.  I send a message to the radio and receive a response I can see about the return of 150 people's Republic of CHINA.  I wanted to move the indicatiors LED outside of the loop, but when I do the data that is generated in this loop never leaves the while loop.  Any ideas on why I can't leave the while loop?

  

  This is basic 101 of LabVIEW and data flow programming.

  A node will only return data once the node is complete.
  A while loop or a for loop will only return data on the wire once the loop has completed all of its code and stopped.

  Our time loops do not seem to be stopped, a FAKE is to send to the conditional stay Terminal.

• Nested while loops

  Attached is a very simple with two nested all VI in loops and two buttons on the front panel.

  1 button, when you press left the inner loop.  2 button pressed leaves the outer loop and the program must end.  I put in a probe at the end of the outer loop and of course a REAL will to the terminator when I press the 2 key, but the program does not stop.  Apparently, all inner loops must be completed prior to the outer loop can terminate.

  Obviously, someone at NEITHER took the decision to design a long time ago, but the rationale is intriguing.  If one end of the loop becomes a REAL it must end, no?

  Although the example is trivial, the problem that it illustrates is a real for me.  I want to offer a panic button stop is a vast and complex and I don't see how I can do with things as they are.

  What you see is the result of the dataflow paradigm used by LV as you said, all the code inside the loop must complete / finish before the outer loop stops.

  Providing one Stop button to stop all in one comprehensive program can be a complex task. The key issue is that EACH loop, function, sub - VI, case structure, structure of the event, the structure of sequence and so on... must stop to stop the loop.  If you have something like a file entry or a reading of GPIB instruments which take 100s of milliseconds or seconds to complete, the shutdown will take at least that long process, assuming that the tedious node was running when the judgment was issued.

  One other point: you put inside terminal 2 touch it the case of the event that responds to the key. Which ensures that the button will be read so the mechanical action works as expected.  With her out of the loop it will only play once.

  A registrant can be used to 'spread the word' when it's time to stop.  The time-out he will keep waiting forever and will also allow the other parallel inside code while loop to run during waiting for him.

• Transfer a license - your system sends me into a CLOSED loop.

  I tried a few weeks to transfer the license Photoshop CS5 to another owner to my account with little success. Your system always sends me in a CLOSED loop.  My next attempt was to fax the form to the number on the form to transfer about 1.5 weeks ago and I have had no response.  The license is transferred? How will I know? I can't save it on my account and it does not matter where in my account.

  I finally got the license transfer accomplished.

  However, the only way I could do that was to spend about an hour on the live chat.

  I never found a way to get even a case number issued outside support cat.

• You can run a loop an external mp3 using Media display

  I'm loading external URLS mp3s and I added the media display component to play. Is it something in the MediaDisplay that will leave you the loop them? Right now they just play once and stop.
  
  Here's how I play my mp3s:
  
  controller.autoPlay = false;
  controller.setMedia (artistSong, "MP3");
  
  {play_mc.onRelease = Function ()}
  Controller.Play ();
  }
  
  {stop_mc.onRelease = Function ()}
  
  Controller.Stop ();

  You can use a listener function to listen to the "full" event, and then restart the player. See the LiveDocs here to know how to implement the listener:

• FPGA interface of data acquisition

  I have a repetitive loop in a PXI-7813R producing reasons. The output of the PXI-7813R is TTL, but I need 0-15V levels. In the same PXI chassis, I have a DAQ (PXI-6528) hardware that can handle the voltage levels. The question is, can I somehow link the the 6528 7813R patterns using PXI backplane and leave this market while I wear the use of PXI rack for other functions?

  Thank you

  Andy Quick

  The problem with the PXI-6528, is that it is software programmed.  Which means trigger won't help you here.

  What you need to do is to do some work of material.  You can have the PXI-7813R output profiles and drive an opto-coupler or FET circuit to change the level of voltage of 15V.  Or maybe there is there a digital stamp which can output 15V for you.

• Confusion between the MSO triggering behavior

  Hi people,

  I see some behavior confusing trigger on the ASM and I hope someone can help me understand what is happening.

  I have my FGEN you ed enter the two inputs of the oscilloscope and extinction of output. In the standalone VirtualBench, I put the FGEN for outupt a 1 Hz sine wave. Then I run the attached vi, which is just data collection. When I asked him to collect data on the same channel, as is the trigger, it fires once per second, which is what I expect. When I ask him to collect data from channel 1 and trigger off channel 2, or vice versa, it fires as fast I leave the while loop execute. This can be seen by the timestamp of trigger and also the chart update. This isn't what I expect, because I do not expect the choice of the data channel to influence the outbreak.

  Also note that I put the time pre-trigger at 2 ms, but it is 4 US when I question him. I don't know what changes this value. This may or may not be related, but happens to whatever the configuration of trigger/collection of data.

  thoughts?

  -Allison

  You don't set a time sample rate or acquisition. If you want to than to keep the settings that you made in the application of VirtualBench, you must set 'Reset' to 'false' on MSO initialize VI. Otherwise, they get to the default values. The default values for the acquisition and the rate of sample time are 250 MHz and 4 US, respectively. You set a time 2 ms pre-trigger, which goes far beyond the acquisition time, so he gets converted to 3,992 US (which is the largest value for pre-trigger, we can use with a US 4 acquisition at this sampling frequency time).

  In the intervention itself, in the API VirtualBench, you should activate the channel that you want to use as a trigger. If you configure an analog channel without mail in a trigger, your type of trigger gets under duress to a trigger immediate (you can see with the OSM query trigger Type VI). It was by design, even if I agree, in this particular case, it seems counterintuitive.

  The solution would be to allow two channels, but then only chart the channel you are interested in (you can use the table of primitive Index on the waveform to choose individual channels).

• How to create a Structure of the event, repeating a task until a push a buttom

  Hello!

  I want to make a program that repeats a task until a push a buttom (indicating to begin another task). I know how to do this with a structure of the case, but I want to know how to deal with the event. Any idea?

  OK, I'm going to help you a bit.

  

  Here's how it works: the upper part (producer loop) will pass the value of the OK button (switch released) to the Message Handling loop (consumer).  When the button is true the consumer runs the code in the case of the real and enqueus another loyal to himself and then wait 1 second.  When the OK button is False, the value false is appeared on the front of the queue and the message handler runs if false, empty the rest of the queue and waits for the next message the event loop.

  The Stop button (by releasing Latch) exits the event and the queue is destroyed causing the Dequeue return an error and leaves the message loop.

  This is obviously an extremely simplified QMH.  To read up more about concepts go to file > Create Project > and click on the "More information" link

  

• Data in table, overwritten by the null value

  I work on writing a VI that simulttaneously reading speed and pressure, then record them on separate tables.  Hit a wall at about 90% of the way through.

  The data (represented by random numbers for testing sake) comes in this central loop case then a VI "add to the table."  Here is where it gets Sticky: when I use a null at the beginning of this table (top of the page highlighted) my data continually gets crushed in the row of the '0' table of each loop.  But when I leave aside the value zero (low highlighted) my data are added to the table very well, but when I stop the VI together and restart, the new data values are just added at the bottom of the table.  Any help would be appreciated.

  Forgive my drawings Caveman to a VI, learning of the system on mine and just happened to a point of optimization.  Thank you!

  -Blaster

  

  Hello Blaster,

  What you did (perhaps accidentally) is created a uninitialized shift register, which will retain its value until the VI leaves memory. This can be an extremely powerful tool and can be used to create things like Motors of the Action, but if you need to erase the data between tracks, you will need to do additional work.

  Looks like what you want to do is to maintain the value of your table, while the application is running, but clear is when restarting the application - which is correct?

  If this is the case, then you have a few options.  My recommendation would be to leave the uninitialized loop and use the primitive 'first call?"to check whether or not it is the first time your processing loop reiterated and replace the table 'used' with an empty array and null.

  You might also consider using initialized worldwide feedback nodes, or half a dozen other methods that have benefits and different disadvantages.  Congratulations on the job through the application, by the way!

• Panel to freeze after moving on graph

  Hi all

  I have a VI with a graph and various controls. The user configures the settings and see the results on the graph by using a loop of events and then press start. Once you press start, the block schema leaves the event loop and executes the actions related to the material.

  I discovered that, if after pressing start the user moves his mouse over the graph, the façade freezes. If I remove the event 'mouse move' in the loop of the event, it is not. This gel that happens after the user pressed start and once the event loop has been exited, so it should not affect anything. The block scheme continues to flow and the VI normally leaves, but for the duration of the user cannot press what either on the front panel.

  I have attached a simplified version of our code. There is a loop of events with moving the mouse and start, and after that, she left the event loop and waits 30 seconds. If you move your mouse over the chart during these 30 seconds, you will be able to press on tabs in the tab control. If you do, the façade freezes and you can not press these tabs any longer.

  The solution that I use now is to make the invisible graph after pressing start, but this is very inelegant. Removal of the mouse move event is not an option. Does anyone have any ideas why this happens and how to solve?

  Thank you

  Danielle

  Your VI is password protected so I have no idea what actually makes your code. If you are using a structure of the event, I think that your 'mouse move' event has verified the following. If so, then uncheck the box to see if that helps!

  

• How to reach an average of three analog inputs of the analog Arduino pins

  Hi, I'm using Interface Labview for Arduino. I correctly interfaced Arduino with Labview and acquired of entry using the analog potentiometer. But now I want to take three signals at once and want to average there. If someone knows how to do it please change below program and fix it.

  I just have three readings in a loop FOR.  Create a table to store the channels to read and leave the auto loop on the channel and autoindex value index.  This will create a picture of your reading.  Then just use Mean.vi to get the average.

• code error-50103. Program hangs after the departure of task, readout and task of clearing.

  I'm having trouble with this unique analogue read. The situation is the following. I have a thread that executes a task. The task runs for continuous, but sometimes based on acquisition

  a push of button in the GUI I need one analog reading from a single channel. I firstly to stop the first task, and then create the next task, read and erase and stop it.

  This function is also called via a timer to get a temperature and a resistivity of reading. The timer calls are interested in the temperature and the pressure of the button wants the resistivity.

  Its the same function but can be called at two different instances. I put in a thread variable secure to ensure that he expects to be each other before reading again. It crashes right away,

  It blocks randomely at about the 6th or 7th instance of analog read.

  My first guess after reading the forum LABVIEW on ni.com, is that he doesn't like when I start and disable the task over and over again. Here is the fucntion is called with a handshake goes, but the

  key to watch is the analog read. The handshake stops the task running in the thread momentarily to analog playback and then it starts again.

  start a new task with a single read analogue.

• problem with the data record

  Hi, I'm new to LabView so I know that the thing I'm doing is relatively easy, however, I'm stuck.

  I made a small program that gets 5 steps (for now replaced with random numbers) and as well as the date and time data in the text file. I intend to run the program for long periods of time, so I want to increment the file name/path every hour, but after the addition of this part of the program does not create any file, although the program runs without error.

  Block diagram is attached, could someone point out to me what is wrong and what I should do to reach my goal?

  Thanks in advance!

  Hi marcis,.

  Acually, the logic of the program was completely wrong.

  1. your comments the file path will never help you. Because after leaving of while loop, the structure of matter will run once and LV will stops running.

  2. open and close the datalog only once file. Try to make all your manipulations between opening and closing your file datalog. Otherwise, it will be difficult to manage when you develop your code.

  3 case construction outside the loop is meaning less. If you want to run the program permanently, place all functions inside the while loop you want to run. While the loop will run continuously until you get satisfied.

  4. incorrect data streams. All programmers need well with the data stream.

  Just go into the basics of labview here and try to realize your logic again
