• storage of the data output of while loop

  Hello

  I have a data acquisition system set up to read the couple of a transducer. The output needs to be fed with an excel document, once the program stops running, or when a key is pressed.

  with the current code attached, the excel document is created, but it only shows the most recent series of data. How to make the table to store all the data coming from while loop?

  Ive only been programming with labview for two weeks, so chances are that it is something simple, but please help us in any case.

  To get what you expect, the Terminal output of table a while loop right click and select the option activate Indexing. Usually if you want to save data use queue to pass data inside the while loop to another loop/VI and perform data recording. For all that you have examples, please do a searc in LabVIEW help > find examples.

• Save all the data for a while loop

  I already asked a similar question, but it is perhaps not very clear, and there are a few concepts that I did not understand.

  1. I have a keyboard to generate flow DTMF signal (I call it stream because it contains several shades that consist of a full phone number)

  2. I would like to save it as a wav file, but I guess that another format is correct and because the writing on a wav file does not support add so for this particular case, I use writing waving instead of writing to wav format

  My approach is to have a structure of queue so that I can write each iteration results in a file.

  (i) when I try to retrieve the data, there's nothing but 0.

  (II) my intention is to get 8000 samples per second (fs = 8 000) but he back up data so fast

  I have attached the file so if there is a way to solve problems, please help me.

  This vi includes many elements discussed above. There are no provisions for the intervals 'no signal '.

  Changes: Replaced with native features of LabVIEW Mathscript node. Mechanical Action to latch release button.  Cluster to array replaces Unbundle and table to build. Reshape the table to match the shape of the keyboard. Separate searches for frequencies of line and column. Note that this is easily extensible to handle the 4 x 4 keyboard. Structure of the event added. Added the stop command (but not implemented stop to the loop of the file). Added indicators for diagnostic purposes. Added FFT spectrum and graphic.

  I disabled writing to part of the file for testing.

• How to send the value of inside while loop outside

  Hello

  The goal of my project is to control the height of a ball in a tube (there is a fan down low to lift the ball to the top and bottom) and a Top ultrasound sensor read the distance of the ball.

  I am currently using a PWM signal to control the speed of the fans (which works fine) and I use the VISA blocks read/write to communicate to my sensors (which works also very well - I can get the distance to the ball - when I move the ball up and down changing the duty cycle).

  My problem:

  Now, to create a control problem, I need read the distance of the ball, have some sort of controller and feed in this output as my new duty cycle for the fans... However, I need loops I have (running fans and continuous sensors to run (I guess? unless there is a way around it.) so the fans continue to work and sensors keep reading.) I need to get the measure of the distance of the loop of the sensor (after its been read) passed out of the loop and to be updated of course - then calculations can be made on that and then can be used as my duty.

  Someone in a way that I can do this? Its all tied to your reference, version of labview 8.6.

  Thanks heaps!

  Nick.

• Sends the data backend Java

  What is the best way to send a flex object to a java backend and then do something about this on the server? I have a table that contains a custom class. When the user clicks on send, I want to send the picture to Java, then get the content of the table to handle the content and write it to a file.

  I have a remote Java object I want to send the data, in order to manipulate it. I don't think that I need a remote object to represent the purpose of flex, but because that would mean that whatever changes I do object in flex continually is sent to the back-end right? I want to just send it in one appointment once the user has finished editing on the front-end server.

  I found XML serializers that people did that recursively go through the object and create XML. It must then be deserialized on the coast of Java. I thought that there must be an easier way. Is there a library or something for this?

  Perhaps, I do not understand the reason for your implementation so don't take no not this personally.  But why would you send a Canvas object, which is part of the view on the server?  If you are only wanting to send the data contained in the text to the server for processing objects you want to do is create a ValueObject (TransferObject for some) and send it to the server, as well as perhaps instructions you want to send.

  On the other hand (and this is just a blind guess at what you're trying) If you are wanting to send the objects so that you can implement some sort of compilation side server, then you want to send the object to plain text for the Web as one of the settings contained in your ValueObject.  Alternatively, you can use Adobe AIR and zip all of the defined object and send the file to the server where it can be decompressed and compiled.

  Here is a blog post on data transfer between Java and Flex using RemoteClass.

  ATA-transfer-objects-from-Java-to-Flex/ http://pachamuthu.wordpress.com/2009/07/15/using-BlazeDS-to-Send-User-Defined-Data-types-d

  I hope this helps.  If this isn't the case, then perhaps a little more information on what you are trying to accomplish might help.

• Sharing data between multiple while loops, competitor rates

  Hello

  I am trying to Exchange data between competitor while loops running at different speeds.  What is the recommended way to do this?    In practice, I have 12 indicators and 3 cards I would update (on screen) in the slower loop, although the data acquired and stored on disk in the fastest loop.  The image below is a simplified version of what really works my candidacy.

  I currently use local variables and shared to achieve this.  I heard however that local variables are evil because of their use of memory (data are copied instead of who passed by reference).

  Thanks for your suggestions,

• Why convert? What is the advantage? Why convert it before you send the data over the network?

  Hello everyone.

  I have a question quite simple and intuitive. Yet Google does not seam to get the answer.

  Basically, I'm curious why should we catalogued something? It seems to me that it's just a little like a "band-aid" for editing data in conversion to a new data type, when it is not properly declared with an appropriate data type. What would be the advantage of this?

  Furthermore, I see a lot of data type casting to U8 programs before sending it over the network. Various reviews say it's for speed, but I can't understand how it improves speed. The same amount of data is still sent, just in a different type of data. This is overcoming a limitation of the network. The network somehow send smaller data types faster?

  I've been curious about this for a while and have yet to find an answer. Any help is appreciated.

  Thank you

  It really depends on the specific situations.

  For example, some functions explicitly require certain types of data as inputs if they are not polymorphic.

  This means that if you do not convert the data yourself and you will see a red dot forced LabVIEW will do it for you.

  As to why the data was not the correct data type in the first place, it is sometimes inevitable.

  A few examples

  -What happens if you just read a text file as a long string.

  If there is digital data in this file, you need to analyze, and then convert it to a usable type (int, sgl, dbl, etc.)

  -you are given a 3rd part VI, dll, etc. that returns a numeric value as a double, but you need the value to I8.

  You cannot change the output of the function given to you, so what you can do to remedy this situation is cataloged data.

  Somehow, this is my first response, but in a more general sense.

  Many functions down to the level of the OS run in binary.

  If your data are not already in binary, the sending computer must convert it to binary, and then send it, have the receiving computer convert in return.

  Two conversions on each side of the transmission add unnecessary delays.

• Sends the data sequentially to the FPGA to a file during playback

  Hi all

  I am a new user of the Labview FPGA module, and I need your help.

  I have a huge file in my computer and I want to treat my FPGA Module. I have a VI divided into small files first, but to my FPGA I do not know how. My idea is to create two blocks of memory in the FPGA in order to have a structure of Ping-pong, module while the second memory is written the first memory was read and the data is processed.

  The first problem is to forward these data to my blocks (as text and the FPGA does not accept it).

  The second problem is that I don't know if as it is made of wiring will work. Can you help me it wiring? I don't know if data should I wire in the host of the read method will go directly to the data items in the FPGA VI.

  Created memories are 64 MB each. I work with FlexRio.

  Thanks in advance.

  Greetings from King,
  Miguel.

  What you want to do, is create a DMA FIFO to send data down to the FPGA.  Make the data type of the DMA a U8.  Thus, on the side of the host, you just read your data from the file, use the array of strings of bytes and write to the DMA FIFO.  On the side of FPGA, you read DMA FIFO inside a loop TO make your table and then treat.  You may need to use a different DMA FIFO to send data to the host computer.

• Custom DataGridColumn sends the data to the ItemRenderer

  I use the as3 syntax to create a few advancedDataGridColumns and specify to use cusItemRenderer

  by "col.itemRenderer = itemRenderer;". ""

  I have replace the function set the ItemRenderer in the class of AdvancedDataGridColumn customed.

  But the itemrenderer is unable to get the data.

  Is there anyway to get the 'datafield' and 'headerText"DataGridColumn properties in the itemRenderer?

  This is my code:

  / / I create an ItemRenderer to pass to all DataGirdColumns

  var itemRenderer:cusItemRenderer = new cusItemRenderer();

  / / I create some columns

  Col = new AdvancedDataGridColumn (flatColumns [i]. Label);
  col.dataField = "@" + flatColumns [i]. Field;
  col.itemRenderer = itemRenderer;

  public class cusAdvancedDataGridColumn extends AdvancedDataGridColumn
  {
  override public function set itemRenderer(value:IFactory):void {}

  
  var itemRenderer:cusItemRenderer = value as cusItemRenderer;
  
  itemRenderer.parentField = this.dataField;
  itemRenderer.parentLabel = this.headerText;
  
  super.itemRenderer (itemRenderer);

  }

  
  }

  public class cusItemRenderer extends AdvancedDataGridItemRenderer implements IFactory
  {
  
  / / They are always null ~!
  public var parentField : String = null;
  public var parentLabel : String = null;

  function public newInstance(): * {}
  return new cusItemRenderer();
  }

  }

  The itemrenderer set went from an Ifactory, not the actual converter class

  or an instance.

  If the rendering engine implements the IDropInListItemRenderer, it should have a

  property columnIndex in the listData which can be used to find the column.

• mirror of the data in a table separated through trigger

  Another "con" is the difficulty of maintaining the data.  As you say, the performance will be better when doing a query that contains the replicated data, but DML will be slower.  Depending on how often you are DML and how many times you make queries that would benefit the denormalization, the benefit may or may not justify the costs.

  There are many problems involved with triggers, in addition to the performance.  A materialized view can be a better option, especially if you can tolerate slightly obsolete results (i.e. ' stale').

  This sort of thing is often done in Data Warehouse applications, where DML is frequent.  Search for the words "Data Warehouse", "Denormaliztion" and "Réplication" to learn more about the subject.

  Most of the time, people join in situations like yours.

• How to control the rate of acquiring data in a while loop

  I'm trying to use a digital trigger to collect data on the rising and falling edge. The design is displayed as below. Now, I save the measured voltage 1 & 2 to the local variable in the while loop. Hoever, the while loop runs at a frequency of more compared to the structure of the case triggered. So I had a lot of repetitive data.  If I record data directly from structure of the case, it will be recorded as data-0-date-0 because of the ongoing case of fake wire.

  I wonder how to revise to save the measured voltage 1 & 2 at the same frequency of up/down edge triggered? Thank you! I have also attached my current version of Labview program, which takes place in time real Labview 2013.

  Thank you for the answer. Could you be more specific about the use of the shift register?

  The case of false just past the value through.  With this configuration, you agree that the data remain in the son, avoiding race conditions.  It is also more effective than the use of local variables.

  

• Transfer the data to one Compact Z5 to another by using a backup

  Simple question really:

  My back to the top of a compact Z5 be usable an another new compact Z5? (to add all the data saved on a new phone)

  Hi @KevinBaykr,

  You happen to already have a backup made in Companion Xperia? If you do, use the Xperia transfer function inside the software to transfer the backup to your new Z5 Compact.

  If you have not already backup, use an OTG adapter to connect a wired USB mouse to navigate with your broken screen. Go to settings > phone > press the Build number down 7 times, once it is said that you are a developer go to settings > Developer options > enable USB debugging, then choose USB configuration and make sure that it is on the PSG.

  When you now connect your device to your computer, it must be recognized so that you can create a backup in Xperia companion and later use Xperia transfer.

  OK - I'm a fool.  I have a Treo 650 and have had problems of synchronization - lying there.  Today, I had the brilliant idea to delete all my contacts and calendar on my computer and starting over.  I put the phone hotsync and after a few minutes received an error message saying that the sync-ing process was interrupted.  Then I discovered that all the data of contacts and the calendar on my palm has been eliminated.  I thought that I had made a backup, but, just, did a search on my computer (XP Home) and couldn't find any file with .aba.
