How to save data quickly to the high sampling frequency

• Save the high sampling rate data

  Hello!

  I use NI PXI-4462. (204.8kS, input analog 4 / s sampling frequency)

  I want to collect data from "load" (channel 1) and "acceleration sensor" (2nd, 3rd, 4th channel).

  I also want to save data to a text file.

  So I do a front pannel and block diagram. You can see in the attached file.

  The program works well in a low sampling rate.

  However, when I put up to 204800 s/s sample rate, the program gives me "error-200279".»

  I don't know what means this error, and I know why this happened in the high sampling rate.

  I want to know how I can fix it.

  Is there any problem in my diagram?

  Is it possible to save high sampling rate data?

  I really want to samplling more than 200000 s/s rate.

  I would appreciate if you can help me.

  Thank you.

  NH,

  You have provided excellent documentation.  So what has happened is that the amount of time it takes to run the other portion of the loop results in a number of samples to be taken is greater than the size of the buffer you provided (I don't know exactly what it is, but it will happen at high frequencies of sampling high) resulting in samples are crushed.  You might be best served in this case to take a loop of producer-consumer - have the loop you have acquire the data but then have an additional loop that processes the data in parallel with the acquisition. The data would be shipped from the producer to the consumer via a queue.  However, a caveat is that, if you have a queue that is infinitely deep and you start to fall behind, you will find at the sampling frequency, you specify that you will begin to use more and more memory.  In this case, you will need to find a way to optimise your calculations or allow acquisition with loss.

  I hope this helps.  Matt

• How to save data in the text file of Spartan 3

  Hi all

  I would like to kindly save the data table text file or a spreadsheet on vi using fpga spartan 3e as an fpga target. Once I added all the functions related to the operation of file, it gave an error that these functions are not supported by the target device.

  could you please help me with this

  Thank you

  Rania

  Hi David,

  Thank you for posting. You use LabVIEW? If so, what version of LabVIEW FPGA do you use? You use a host VI, or any deployment of code at your target to run? The file IO VI probably won't compile to target because they are not intended to be used on your host computer. Resources and the paths of files do not exist on the target FPGA, but rather on the side of the host. I have included a link below that describes how to transfer data between the FPGA and host. I hope this helps!

• How to save data in the spred sheet file that is?

  Hello

  I want to save a table in the same spred sheet file I read my external device.

  here as an attachment, I enclose the vi.

  This is the example of data I want to save for example in the first column I want only numbers with no floating point.

  and remaining column is everdata, it should be the same.

  As an attachment, file name 11 is the same file that I want to, but I always get as file attachment 2,

  can you please guide me how can I get data that is displayed in the table of labview.

  Thank you much in advance.

  This code - using the Format to a string - creates a very similar to the log file output 11. You can write the string to a file with write a text file or write the string array with write to File.vi of the worksheet.  Write to File.vi of the worksheet internally converts an array of strings for what is in the string, and then wrote this text, so it makes more sense to use only write to text file. Write to Spreadsheet File.vi help will make additional copies of the data, which can become a problem if the dataset is large.

  Read the detailed help for Format string for more information on the available format codes.

• How to save external files in the logical project?

  Didn't know how to phrase the question. Here's the question. Ex: someone sent me an audio file to add to my project of logic and I have it drag my desktop and everything is all fine and good. I save the project, and then proceed to remove the audio file from my office. I then go back to open my logical project and it says that it cannot find the file. In Garageband, once I recorded an audio file project, it is always there even if I deleted it from my office. But in the logic, it does not do this. Is it sort of permanently save/integrate a file in a project of logic, so that I can remove from my desk and there not try to pick him up every time at the opening?

  

  Hello

  You must have the logic to copy the files:

  For new projects, use file > save and make sure that "Copy the following files to your project" is enabled for audio files.

  

  For existing projects, or file > save as, then check the same box

  or

  File > project settings > active

• BlackBerry Smartphones Email attachments - how to save an attachment to the device memory or media card?

  I have a BlackBerry 8310 Curve, which we got up to speed up our translation services.  the thing is that we have received a document attached, and we could not know how to SAVE the attachment to either the memory card or peripheral support, which would then allow us to transfer it directly to the laptop to work on.

  The temporary solution we found was to convey the message to a different email address and download it to your computer. For some reason any later we could not attach the document to email the map of media either, so we had to email from the laptop to the blackberry, and then forward it to the client.

  So, my questions are:

  How to save an attachment to an e-mail message OR the card memory or device support?

  How can I attach a document to an email when ATTACH it to does not display the file in the folder? (of course I've already put it there)

  and as a side note

  Why I could open the email attachment I had forwarded to the blackberry, but I could not open the original document (the two word .doc) sent customer e-mail.

  Here are the details of my laptop: Win XP Home edition, Service Pack 3

• How to save downloaded and open the PDF directly into my laptop, compared to saving the file in the cloud? Can I remove DC and install Acrobat Reader, which is thin and easier to use for my needs and much, much more secure?

  Somehow, I downloaded and installed Adobe alleged DC update for the existing acrobat Reader installed on my laptop.

  DC app has been a disaster for me in terms of generation of convoluted navigation and extra work.

  In addition, I do NOT trust or want an application based on a cloud because of the deep and hard-learned risk, privacy and security, as well as the occasional loss of connectivity online and access, what urgent needs can get GROUND in terms of use of such an external cloud-based application.

  Issues related to the:

  Hi stephenf95557665,

  (1) you can simply save the file on your computer as allows you to save in the older version of the player, it is not necessary to register I your cloud of document.

  If you save the file to the document cloud, you will be able to access any system from anywhere.

  (2) If you still think earlier version users need, then they can probably uninstall the last being & reinstall the old version using this link http://get.adobe.com/reader/enterprise/

• How to save a copy of the file? (simple javascript needed)

  I'm a noob, so need a Javascript/installation for InDesign CC script, which runs automatically when a file is openand saves a copy of the document to a specific folder, to the present time (i.e. "c:/file/filename_COPY_6_MAY_2014_23_59_59").

  This code is just for this work? :

  var dmd = app.activeDocument;
  var oldDocName = dmd.name;
  //make new file
  var newDocName = oldDocName.substring(0,oldDocName.length-5); //removes ".indd"
  var dd = new Date;
  var NewFile = new File("/c/backups_folder/" + newDocName + dd.getDate() + "_" + dd.getMonth() +  "_" + dd.getHours() + "-" + dd.getMinutes() + "-" + dd.getSeconds() +".indd");
  //copy
  oldDocName.copy(NewFile);
  
  
  
  
  
  
  
  
  
  

  Hi all

  I don't think that the link you have provided on stackflow meets your problem and certainly not the best way.

  Hopkins response for sure does not seem be correct (sorry)

  I think that my script below is the best method.  Don't lead to annoying delays in file open.

  Put it in your startup script file
