How can I write only 1 sample every 0.5 second to my excel sheet

It's the VI I work on... everything works fine but I have too many samples per second on my excel file... I just need 1 sample every 0.5 seconds. How can I solve this problem?

Thank you very much

The default values on the DAQ Assistant 100 samples acquired at 1 kHz, then each cycle you get 100 data points.  If you want only 2 points to a second and avoiding the is acceptable, could I plug "1" on the number of samples on the DAQ Assistant (or right-click and select properties to configure the node) and use a software or a timed loop delay in the loop like "wait until the next multiple of ms.  Alternatively, you can use screws more advanced such as 'DAQmx read' to get the desired behavior.  Remember that the data acquisition will be back as soon as he gets the data that you invited to capture, so you'll probably need something to keep periodic things between cycles of the loop unless you want to move to continuous hw timed operation of data acquisition.

  • How can I put ONLY 9 tabs, NO 15, on the new tab Page?

    How can I put ONLY 9 tabs, NO 15, on the new tab Page?
    (First OFF... Please do not read this as being written by an angry person.) I'm just frustrated with the browser that I liked for years. I hope someone can help me)
    For a long time, I had my Firefox (version 33.0.2 - even if I don't remember getting mentions "update") defined so that every time I clicked on the tab new symbol '+' to create a new tab (which has the "new tab Page" on that), the NINE inch nails would be shown for my SELECTION and PIN sites. I LOVED!
    Yesterday, I opened Firefox and NOW when I click on the '+' to open the new tab Page... FIFTEEN thumbnails appear, 5wide x 3down, (and to be honest I probably would have the habit of 15! ha).
    Here's the PROBLEM: NONE of the thumbnails are "compressed". They ALL have "liberated" up yellow icon to the left and clicking on does nothing to remedy this of course. Other that THAT, everything else behaves normally. (that is to say moving the thumbnails, deleting, swap... I just can't pin THEM!)
    FINALLY, I prefer my 9-repositionable decals on the new tab Page.
    I went through ALL the options on the side, upside down and backwards, and I just get more frustrated.
    Can someone help me?

  • How can I transfer only the music I want?

    Hello.

    Our iMac iTunes is full of music for the whole family. How can I transfer only the songs I want on my iPod and my iPad?

    Second...

    When connecting from my iPad to my iMac USB cable the iPad goes into sync mode and transfers all sorts of things on the iMac and gets things from him. All I want is to transfer my music? How can I do this?

    Create your own playlists in iTunes.

    Connect your iDevice to the iMac - in the main iTunes window select your iDevice - menu drop-down upper left box located to the left of the music-movies, etc.

    You will see a list of 'Settings' for this device - select a tab and check the boxes of what content you want on your device.

    Also in the Group of settings select 'Summary' - from there, in the 'Options' section, you have a few additional items to choose from.

  • How can I close only 1 session, without closing all sessions, when you run several at the same time?

    I run normally 2 sessions of Firefox. Currently I have 3 sessions running. How can I close only 1 session without closing all? When I choose "File" and then "Exit", all sessions nearby.

    Firefox does not work more 'sessions', you see several windows running in the same process. IE runs each window in its ' own process and Chrome runs each tab in its' own process, but Firefox running in a single process.

    Do not use file > outputis to completely close Firefox, do not close the window you are looking at when you use this command. There was formerly a command to close this window on the file menu, but who took a few versions ago. You will need to use the X in the upper right of the window to close this window and leave the other open windows. Or you can use {Ctrl + Maj + W} close the window that is to the point (where you look).

  • How can I write a letter in french with Pages

    I use my computer in English, and I have to write an essay in french

    So, how can I write a letter in french with Pages

    Hi Luke,.

    If you are familiar with the French keyboard layout, you can move from the keyboard to this provision.

    If not, you can acess of the accents you will need the English KB layouts using (for example) option-~, then press e to e, or -e option, then press e to e. see the viewer keyboard for other options. Open the keyboard Viewer, and then press option key to display the keys to use for each accent.

    If all the accents you need are not available from an English keyboard, you can still list a French KB language as a 'second choice' and switch to it when you need an accented letter.

    Choice of the keyboard are defined in system preferences > language and text > input sources. If you choose more KB a page layout, the entry menu (a flag) will appear in your menu bar. The indicator shows the currently active KB.

    Narendra.

    Narendra,

    Two characters can type cast into a uint16 you VI supports.

    To summarize. Take one (4 bytes). Flatten it to a string (4-byte) divided this string into two parts of 2 bytes each. Cast in u16 (16 x 2 = 32-bit).

    However, if you really want to follow the IEEE standards then you will need refer this KB. His is not that simple, but seems closer to what you are looking for.
