• How to save the data of different rates in a single VI?

  Hello

  I tried to acquire 2-channel measurement of voltage at 10 kHz and analyze data, finally to save the data to both 1 kHz and 1 Hz. What I did is this loop of producer/consumer use to do the work of recording at different rates. I have queued all the data in the main loop, and then removed the data and write it to the file in other loops. I added "wait = 1 ms' a consumer loop for recording data at 1 kHz (loop of fast logging) and added" wait = 1000ms' in another loop to get the slow 1 Hz (logging loop) data record.

  My problem is that the data record works fine in the case of 1 Hz, but it does not work for the case of 1 kHz. Although the time-out period defined as 1ms, the interval between two samples in the loop of fast data recording is about 100ms.  Subsequently, 1ms, 10ms, 100ms, 150ms tried in this loop to see what intervals are in these cases. I found that the intervals are same as assigned in the timeout greater than 100 ms, but if the time-out is set to 1ms or 10ms, the intervals are again around 100ms.

  My question is - why I can't reach data record 1 kHz using loop of consumers/producers, while the same way works for the case of 1 Hz?

  Thank you very much

  You are sampling at 10 kHz and you want to back up your data "as if you sampled at 1 kHz and 1 Hz", if I understand correctly.  I also understand that you use the design of producer/consumer model to help with this (a good idea).

  I'm assuming that the producer 'product' a segment of data at a time, to say the value of a second of data or a 2 x 10000 I16 (assuming a 16-bit integer A/D) table you put into a queue and wait for the consumer.

  If you have data at 10 kHz, how do you get representations to 1 kHz or 1 Hz?  There are (at least) two possibilities - average data over the interval of proper time, or (re) sample data.  The good thing is that you can handle the situation 1 kHz and 1 Hz, essentially at the same time and in the same processing loop.  I'll discuss the case 1 kHz - with the assumptions I made, the case of 1 Hz becomes almost trivial.  I'll discuss treatment also just one channel, as it is similarly almost trivial to go from 1 to N-channel.

  If you have 1 second of data sampled at 10 kHz, and will "reduce" 1 second of data sampled at 1 kHz.  Note that you have 10 samples for each data point that you want in the end.  The "Averaging" method said "Replace all 10 points in the average of these 10 points", while "resampling" method said "replace 10 points with, say, the first point, ignoring the others.  An easy way to do this is to use the Reshape feature to transform an array of 10 x 1000 elements of your array of 10000 items 1-D 2D.  Now, you can use a loop FOR an average of 10 items or simply extract the first.  [This is where almost everyone, including me, a mistake - when you put a 10 x 1000 2D array in a loop, you get 10 iterations of 1000 items and we want 1000 iterations of 10 items.]  Oops, what to do?  [Simple - converts 2D array before sending in the loop FOR.]

  So when you have processed your 10,000 points and got both 1000 samples "1 kHz" and 1 "1 Hz" sample, you write each of them in their respective folder and wait for the next item in the queue of the consumer.  Consumer focus on the queue loop, it will automatically 'block', waiting for the producer of the 'feed' some data.  Note that the producer generates data once per second, producing 10000 points for the consumer in the process, but the time to deal with these points and perform the required disk i/o should take only a few milliseconds (certainly not more than 100, even if writing to a floppy!), so you don't have much time to do other interesting things (such as display data).

  Look at the script on the FPDF under 'Scripts' site below

  2002-12-25

  Olivier

  Table with MySQL

  First you must download the file of fpdf.php since the site under the downloads"" section.

  Copy the first block of coding 'Source' from the example script and save it under-mysql_table.php

  Next copy the second code block and insert it into a new document in DW, modify the code as shown in red below and save it as pdf_output.php - make sure that the paths to include the mysql_table.php and the (fpdf.php file which is included in the mysql_table.php file) are correct.

  Also change the connection to your database in the code below.

  require('mysql_table.php');

  class PDF extends PDF_MySQL_Table
  {
  function Header()
  {
    //Title
    $this->SetFont('Arial','',18);
    $this->Cell(0,6,'Database Data',0,1,'C');
    $this->Ln(10);
    //Ensure table header is output
    parent::Header();
  }
  }

  //Connect to database
  mysql_connect('server','login','password');
  mysql_select_db('db');

  $pdf=new PDF();
$pdf->AddPage();
//First table: put all columns automatically
$pdf->Table('SELECT No, Calon, ID, Jurusan, Undi FROM candidates order by Undi desc');
$pdf->Output();
?>

  If you have set up properly and navigate to - pdf_output.php - it should produce a pdf of the extracted data in your database.

  A draw back is it uses mysql and mysqli - which is not an immediate problem, as long as you do not mix mysql and mysqli - as this is a stand alone page, it should be ok. (and of course as long as your server still supports the mysql extension)

• How to save the data in a form called?

  Hi all.

  I have two froms.like FORM A and FORM b.

  I have a button on the FORM B.

  When I click on this button, FORM B and FORM data should be store in the database...

  I wrote something like this in the form B

  when_button_pressed->

  commit_form;

  go_form ("c\user\babu\FORM A.fmx");

  commit;

  Here, my problem is when I click on save button only saved FORM B, FORM A not memorizing the data in the database.

  Please help me and tell me where the error...

  Post edited by: N.B.Babu

  I guess that the modules form a calls B with OPEN_FORM module (..., SESSION), IE. Module B works in the new session of database

  (by the way, the database connection is the same, because the connection to a database can go several database sessions).

  Your code cannot save the data in the two sessions of database:

  commit_form; -This saves the data only from module B (because A module work in diferent database session).

  go_form ("c\user\babu\FORM A.fmx");  -Now you in module A.

  commit; -This has no effect, you are now on the module to a.

• How to save the data to the new file, when you press the button

  Hello.

  Run a program that reads data recorders seconds and displays a trace on the screen.

  What I want, is that when I press a button, the program will ask for a file name and begins to record data to the file, and continues to do this as long as the button is pressed.

  When I press the button again, the program asks the name of the file again, so I can select a new file to write.

  I've included a simplified version of my program that works by asking the file name at the beginning.

  How can I change the program it starts a new file every time that the key again.

  Kai,

  I changed the example that I gave you to LV8.0, but I have never used the option 'Save for the previous version' before, so I don't know if it will work.

  I have combined the start and stop of recording in a single button (just change the text to all what you need) and I used the 'value' property to pass the path between cases. The path can be formatted as you have in your version, don't forget to use the string conversion function filepath.

  Just in case where it doesn't work on your version of LV I've attached a screenshot of the block diagram.

  Hope this helps, let me know if you have more problems with this.

  Easy.

• during an update lots of my profile folder has been put in a folder on the desktop marked the old data. How to restore this data file

  During a bet to update, automatic update of windows has started and some how much my profile data has been removed and stored in a file on the desktop. There is a simple and easy way to restore this folder from the current firefox?

  You can use the contents of the Old Firefox Data folder to "roll back" the refresh, but this involves several steps. It's probably even faster than the recovery of individual files and load those into your new profile.

  Check in the folder 'Old data Firefox' update adds a folder with a random semi name on your desktop. If there is only one, that probably has your old settings and Add-ons. If there is more than one, you'll want to work with one who has been updated recently.

  Once you have identified the profile folder, that you want to restore, here is my "old profile resurrection suggested procedure:

  Overview

  Here are the steps described in more detail below:

  1. Create a new Firefox profile
  2. Delete all of this profile folder
  3. Copy in all of the old profile folder

  Create a new profile for Firefox (Windows)

  Exit Firefox completely and start up in the Profile Manager by pasting the following in the Windows search, or the Run dialog box by pressing ENTER:

  firefox.exe -P
  

  Note: any time want to switch profiles, exit Firefox and return to this dialog box.

  Click on the button create a profile, give it a name like OldSettings and skip the option to change the location of the folder. Select the new profile from the dialog box, and then start Firefox.

  Open the new profile folder in Windows Explorer

  Firefox in the new profile should look like a new installation of the plant. Open the troubleshooting information page by using either:

  • button "3-bar" menu > "?" button > troubleshooting information
  • Menu help > troubleshooting information
  • type or paste everything: in the address bar and press Enter

  In the first table, click on the view file"" button. Firefox will launch your new profile folder in Windows Explorer.

  This folder open, switch back to Firefox and get out by using either:

  • "3-bar" menu button > button "power".
  • (menu bar) File > Exit

  Firefox is closed, the profile folder must be front and Center, or you can activate it by using the taskbar.

  Copy old data instead of new

  In this new profile folder you just popped open - NOT the one on your desktop - select all content (you can use Ctrl + a) and delete (you can press Delete on the keyboard).

  Leave this window open, open or switch to your folder of old data of Firefox. Consult your old profile folder. At this level, you should see a folder named bookmarkbackups among other things.

  Select all (Ctrl + a) and copy (or right-click > copy or Ctrl + c).

  Switch to the empty profile folder in another window and paste (or right-click > paste or Ctrl + v). This may take a few minutes because some files are large.

  Launch Firefox

  Firefox should start in this 'new' profile with the old resurrected profile data. Success?

• Save the data in a horizentall

  Hello

  Any that offered little help on how to save the data in a portrait. As a result of my attachment all my datas saved az a tables!

  And also, I'll be glad if you told me that I can add text in front of my data as an outamaticlly to explain?

  Any suggestions would be greatly appreciated! Thank you very much!

  Sincerely,

  First convert your string numbers using decimal channel number.  Once your numbers have the appearance of a string, you can format the text with them.  If finally, you can use concatenate strings to concatenate (add all channels) your number in the string with another text format:

  

  This code would create the following string:

  

  Then, you can save your all channels on a line using the same method as above.

• 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!
