  Hello

  How to write data in mode intertwined with TDMS C DLL 2.0?

  I use DAQmx features in Visual Studio C++ without Measurment Studio.

  This function returns the data in interlaced mode.

  How can I configure the functions of DLL C TDMS to store this data in the tdms files?

  I see that it is not possible with the PDM version 2.0 with 1.0.

  Thank you

  -TDM C Dll is not able to do

  -TDM header writer may be usable for this but is not able to be used for tdms files.

• DASYLab how to write data to a file every 15 minutes

  Hi all

  I use dasylab and datashuttle/3000 to record data. What I want to do is to write data to a file every 15 minutes. I use the milti-file, which can write data to the file diffenret, but how do I control the timing, as the journal data every 15 minutes automatically.

  The other problem is that I use FFT analysis of the frequency spectrum. How can I determine the value of frequency where the peaks that happens.

  Thank you

  Write less data in the file that you have collected requires the reduction of certain data.

  There are three techniques to consider.

  With an average or an average of block - both reduce the data by using a function of averaging, defined in the module. To accomplish the reduction of data, choose block or RHM mode in the dialog box properties, and then enter the number of samples/data values that you want to reach on average.

  Average - when you reduce the data, you also should reblock data using the block length of the change in the output parameter. For example if you enjoy at 100 samples/second with a block size of 64, the average module configured on average, more than 10 samples will take 10 times longer to fill a block. The initial block represent 0.64 seconds, the output block represent 6.4 seconds at a sampling rate of 10 samples/second. If you change the size of output in one block, the program remains sensitive.

  Average block - average values in a block against each subsequent block, where the average is based position. The first samples are averaged, all second samples are average... etc. The output is a block of data, where each position has been averaged over the previous blocks. This is how you will be an average data FFT or histogram, for example, because the x-axis has been transformed in Hz or bins.

  Second technique - separate module. This allows to reduce the data and the effective sampling rate jumping blocks or samples. For example, to reduce the data in 1000 samples / second to 100 samples per second, configure the module to keep a sample, jumping 9, keep one, jumping 9, etc. If you configure to skip blocks, you will not reduce the sampling frequency, but will reduce the overall amount of data in a single block 9, for example. It is appropriate for the FFT data or histogram, for example, to have the context of the correct data.

  Finally, you can use a relay and a synchronization module module to control. For example, to reduce a sample data every 15 seconds, configure a generator module of TTL pulses for a cycle of 15 seconds of time. Connect it to a Combi trigger module and configure it to trigger on rising and stop the outbreak directly, with a trigger value after 1. The trigger output connects to the X of the relay command input.

  In addition to these techniques, you can change the third technique to allow a variable duration using a combination of other modules.

  Many of these techniques are covered in the help-tutorial-Quickstart, as the data reduction is one of the most frequently asked questions.

  In regards to the FFT... use the module of statistical values in order to obtain the Maximum and the Max Position. The Position of Max will be the value of the frequency associated with the Maximum value. The output of the statistics module is a single sample per block. Look at the different FFT sample installed in the worksheet calculation/examples folder.

• How to write data in an Excel spreadsheet protected (with unlocked cells)?

  Hello!

  I have LabVIEW 8.2 and I often use the report Generation Toolkit for Microsoft Office' to save data in Excel spreadsheets. So far, I only used the leaves unprotected.

  But right now, I have an Excel worksheet protected by some cells unlocked. If I open the file using Excel I can fill these unlocked cells without any problem. However, I am not being able to fill these cells unlocked using LabVIEW and the Toolbox. I have a few questions:

  (1) is it possible to use LabVIEW to write data in a protected Excel worksheet, even though she has unlocked the cells?

  (2) if it is possible, how can I do that?

  OBS: I noticed that if I unprotect the sheet, I can write data to the file. But I don't want to be protected and the protection of the sheet, since users will not have the password.

  I hope that I was clear. I really appreciate any help you can provide.

  Thanks for the replies.

  Use ActiveX I could write the cells individually. By doing this, I could write in the unprotected cells without any problem. hour

  Probably, the Toolbox has been activated somehow the overall protection of the spreadsheet and Excel was not allowing writing.

  I had never used before ActiveX, so I had to learn it from scratch. I was looking for some tutorials on the internet but I have not found much information easy. What struck me the most help is an example that comes with LabVIEW named "Excel - write Table.vi. After some tests, I was able to open my data protected from the worksheet and fill in the unlocked cells.

  Thank you guys!

• How constantly write data in a txt file

  Hello
  first of all, sorry for the bad English, but I have a problem to write data continuously to the txt file... I have a chart 2D with values based 2 sliders (sliders values) and some functions I want to interpolate the value by using the bilinear method... and after that the value of the sliders, interpolated value and the value of the closest points, I want to write to a file txt... for every 2-3 seconds perhaps, it would be ideal to be formatted as ::
  x y f f1 f2 f3 f4
  ..   ..  .. . .. .   ..   ...  . ..
  ... ...  ..    ...   ...   ...   ...

  but... first of all I have a problem with writing data, because every time he deletes old data and simply write a new and it is not horizontal... I am very very new to this (it's obvious) and any help will be very grateful 
  Thank you

  

  Diane beat me to it, I made a few changes to your code, so I'll post it anyway.

  

  As proposed, please go through the tutorials.

  I added an entry to the worksheet at the end node just to show it can be done at the end so. Table of building on a while loop is not very efficient memory, but it's just to show you what can be done. If you plan to go this route, initialize an array and use the subset to the table replace.

  All the best.

• How to write data from the acquisition of data in NetCDF format?

  I connect to a set of data from the sensor through the DAQ assistant and want to write all data in NetCDF format. I have the required plugins installed, but still can not find how to do this.

  Or the labview can only read the netcdf files, but cannot write it! Please let me know if there is any other way out. I have looked everywhere but could not find something useful!

  Thank you

  Hey,.

  Sorry, the sheet in effect only allows to read NetCDF files, not writing to the NetCDF format.

• How to write data OR DAQ of buffer to stdout in ANSI C?

  I'm totally new to NIDAQ. I searched this forum and not found a solution to my problem - everyone works with LabView, not in ANSI C. I use NIDAQmx with ANSI C on Windows XP. It is easy to capture data using the ANSI C API provided with the NIDAQ. Data is automatically stored in a buffer provided by the API. Question: How can we get the information from the buffer? For example, if we wanted to taste 1000 samples (let's say, an analog input channel as well as a digital input channel). At the end of the data collection, I want to print the data that have been recorded, for example to the stdout device. Just a small pointer in the right direction would be extremely helpful! None of the files example C (supplied with the NIDAQ) don't file output data that have been recorded. You should know the format in which the data is stored in the buffer, and the buffer structure to access the items in the buffer.

• How to write data at the end of the doc in sense the other way around? [CS6 - jsx]

  I need to move all the entries in my texts spec at He end of the doc. To keep the correct reference overall found entries that I have to deal with in reverse order

  for (i = mFound.length - 1; i > = 0; i--) {}

  .. .etc

  but to invent, how to place entries cannot write off at the end.

  String:

  mStory.insertionPoints.item(-1).select ();

  App.Paste ();

  does not work properly (of course). It does this:

  10.

  9.

  8.

  7.

  6.

  .. .etc

  How to get

  1.

  2.

  3.

  4.

  .. .etc

  ?

  Dmitry,

  Well, I've been basically dealing with moving the notes at the end of the story in the correct order. Anyway, concerning the figures by exposing, there no need to choose things and remove these selections. She considered more safe, like Vamitul too mentioned, to work on the objects. To manage numbers superscript, I would do this:

  app.findGrepPreferences = null;
  // Search just the note contents: lookaround leaves the braces in the text
  app.findGrepPreferences.findWhat = /(?<=\{\{\{).+?(?=\}\}\})/.source;
  found = app.documents[0].findGrep();
  
  for (i = 0; i < found.length; i++){
      found[i].parentStory.insertionPoints[-1].contents = '\r' + String (i+1) + '.\u2003';
      found[i].move (LocationOptions.after, found[i].parentStory.insertionPoints[-1]);
  }
  
  // Now search {{{}}}
  app.findGrepPreferences.findWhat = /\{\{\{\}\}\}/.source;
  found = app.documents[0].findGrep();
  for (i = found.length-1; i >= 0; i--){
      found[i].contents = String (i+1);
      found[i].position = Position.SUPERSCRIPT;
  }
  

  Then first move the notes at the end of the story, leaving behind all the triples of braces. Then, after you have moved the notes, do you a new search on the sextets of braces. Only select and delete, just redefine the content of what you have found and apply an in shape.
