• Generate the analog waveform based on the data file

  I want to create an analog voltage output that follows I have a data file (excel, csv, text (which is easy)).  The data file creates a waveform with equal time between steps (dT =.0034 sec).  After the output through all the data points, I want it repeat indefinitely.

  What is the best way to create the waveform of a data file?

  To create a type of waveform data, calculate the dt by subtracting two values in column 1 and get the array of Y from column 2. If you save the file as a comma separated or tab text file, you can then use the spreadsheet file read. After obtaining a 2D array, you would use the index table and the subset of table functions.

  Assuming you use a capture card data OR for the output signal, you can pass a type of waveform data to a writing DAQmx and set for the generation of types.

• All read old version data file in Labview 8.6 (waveform playback of file.vi)

  Hi, I have a big problem on the use of file.vi in LV8.6 reading waveform to play *.wmf files that were generated LV7.1 program.

  He often appears a message windows, refer to the attached picture file, because I use LV8.6 program to read a considerable number of such files,

  I can't afford all these windows message in my program, please tell me how to get rid of this message.

  Thank you very much

  Hello

  The type of waveform data is in LabVIEW 8.6 differs from the version 7.1, so this conversion is required. This knowledge base article solves the same error: Read Waveform files from old Versions of LabVIEW .

  To prevent the message from appearing, add silentDatalogConvert = true to the LabVIEW.ini file. It is located in the National Instruments\LabVIE 8.6 folder. I hope this helps!

• get the timestamp of waveform data

  Hi all

  I'm coming out of the timestamp from waveform data if this is possible. I am writing to file, but the express vi does not allow for fractions of a second and when I write a string waveform data for use with writing to the worksheet, the data of time is lost.

  any suggestions?

  Use Get waveform components. What part of VI? Writing to a file of measure written fractions of a second.

• 1 table D of waveform DBL file or its

  Hello.

  I am building an application where I have an accelerometer with an interface USB-1208FS samples.

  I have this loop on the inside with a few virtual instruments to display the waveform and frequency of it components. I tried many different approaches to record in a file, but it doesn't seem to work. No file is created even although I am administrator.

  Data that are fed to the filters and these great are "table 1 d of waveform (DBL). Tried to convert other types of data, but does not work. This VI for example 'write waveform of File.VI' does nothing even if it should accept this type of data. It's "waveform table is a 1 d table the you want to write to a file of wave forms.»

  I'd appreciate any help on my way to accomplish this task. With regard to Abraham

  You still have not posted this VI. You say exactly what function and it is inside the loop / out of the loop that wants to say? My only guess is that you use the button stop in the toolbar.

• Filter for waveform data

  Hello world

  I'm trying to filter the noisy analog inputs of 10 channels (DC). I'm sampling of 100 samples/channel at 1000 Hz. My idea is to filter the data with a low pass filter (cut to 10 Hz 3rd order butterworth low freq) and then to calculate the average of each package of 100 samples. Finally, I would like to receive values at a rate of 10 Hz, which can be displayed on the front panel and be written in a file of measures.

  My problem is the following:

  The Express filter VI does not filter continuously after that the VI began. It seems to reset each time the loop runs. The table of 100 samples (white) before and after (red), the filter appear in the image "filterResponse". If I take the average of this table, it is of course less without the filter due to the transitory values between 0 and 0.025 s. I built a simplified version of my VI with only one channel using the VI "Simulate signal" and my concept seems to work well which is permanently (see "filterMeanExample.vi"). I get the idea that it might have to with the kind of dynamic data that is supported by many express VI. But since I'm on the VI KEITHLEY, I do not use the type of dynamic data. In fact, I had to convert a waveform data type to get a vehicle appropriate for the file of the measurement of its release.

  I wonder how to keep the filter VI of reset each time that the loop runs.

  My VI is rather large and contains the KEITHLEY 'Acquire signals' VI which most people do not have in their libraries, so I decided to show only the images.

  Thanks for your help!

  Thanks for the tips, I am set!

  I used the VI of butterworth filter in the tool box to filter on the Panel of the Signal processing that accepts the type of table data. I put the variable ' init/cont' true to prevent the filter to reset its initial States to 0. I guess, it was my real problem before. The Express filter VI doesn't have this option, so I wasn't aware of this feature.

  However, an image of the current value is attached.

  Thanks again,

• determination of the sampling rate and the frequency waveform data record

  Hello

  I write a simple program that collect data from a triaxial accelerometer input, convert it to a frequency spectrum, and then save the time domain and the frequency of the waveforms in an external file separated.  I don't understand how to set the sampling frequency, however.  On the DAQ Assistant, I updated the acquisition mode "Samples continues" and read samples is 2 k, which corresponds to the total number of data points that are collected.  How can I program sampling for awhile, it 30 seconds, for example?  Wouldn't be better to set up a trigger, as it will continue to collect data up to what I told it to stop?

  I also want to save waveform data in a separate file that can be easily seen by other computers that have not installed Labview.  I have currently the program put in place to convert a text string of the waveform of the time domain and then save it in a text file or a spreadsheet.  It works fine, but I would also like to record the frequency wave, which is a different type of data.  How can I do this or is there a better way?

  My program is attached.  Thanks for your help!

  Here's how you can use the shift register to build the table, and also where you can choose to play exactly 100 samples per while the loop iteration.

• So with the new update every attachment I get an Outlook user is converted in a winmail.dat file.  How Apple could make a such big screw-up?  Even when I check gmail via apple mail conversion is made, but if I connect to google, the files are

  Why is each attachment outlook, I get in the Mail now converted in a winmail.dat file?  I don't want to go make an app to allow me to open these files - it is something stupid on the part of Apple - please correct!

• I have an old data file of firefox from a transfer of the computer I did and I want to get all the sites that I had organized how can I do this?

  If earlier I transferred my old files from the computer to my new computer and when I did I tried that my firefox books brands added when I did he just make an old firefox data file. I went in there it has the markings of books, but the problem is it is not really readable a little mixed up and I want to know if I can import it to my only current or somehow get it organized so I can at least see them outside or on a note pad just each bookmark on its own line? I added a picture what it looks like

  You can use the notebook (Firefox/tools > Web Developer) to inspect and edit files in JSON format quite easily.
  There is a "Pretty Print" button to add line breaks.

• Still not get 2016 Outlook and Contacts calendar to synchronize with iCloud. iCloud data file has not been in Outlook but iCloud add-in is enabled.

  I use Windows 10 (v1511), 2016 Outlook Office 365 and iCloud 5.2. Mail is downloaded directly to Google mail Outlook. Calendar and Contacts live in iCloud and work properly in my iPhone, iPad and the app iCloud on the PC. Its just perspective that is not sync with iCloud to get these items.

  In outlook, the Setup program is not set up a data iCloud file ' * APLZOD.pst ' in the account tab data file settings. When you try to install a new data file in Outlook in account settings, the iCloud type available, but when you select what the error message says that this cannot be set in the iCloud Control Panel

  I tried several complete removal and then re - installs to iCloud for windows and have also done with the firewall and antivirus disabled active.

  I also deleted the Outlook data file * *.ost and allowed the installation program rebuild this application fee.

  The iCloud "add to" Outlook "add-ins" is active.

  The calendar, Contacts and tasks of the iCloud Panel section is checked when re-built, but after Outlook is running this section has not been verified and when you try to check it out and apply the change he UN-checks itself.

  Sorry for the long post, but I tried to solve this problem for some time.

  Thank you

  The same problem.  I use iCloud for Windows 5.2 and Windows 10, 2016 office.   Everything worked well for several months until a few months ago, when sync calendar has stopped working.   I've updated iCloud of 5.1 to 5.2 but that just killed altogether.  Tried uninstalling icloud and relocation costs.  No luck.  When the iCloud settings appears, I check the box for the calendar and Contacts.  The driver then disappears.   I check again and it sticks.  But no messages on 'configure '.   When I close and reopen, the box is unchecked.   A few days ago I had the same problems the other another thread where he would show "set up" spinning forever (well, 30 minutes before giving up).   Not sure if it's an Apple problem or a problem of office.  But this is of course a problem.

• Stop the quicktime open .dat file

  I need to download a data file with the extension .dat from a web page link, but when I click it it opens Quicktime. I looked in preferences-Applications to try to change the management of the .dat files, but I see no entry for them. How can I do it gives me the option to save the file rather than open Quicktime?

  You can click the link to the .dat file and use ' save the link under ' to save the .dat on the hard drive.
