How do I create free of glitch signals output in the buffer permanently changing?

Hi, could you point me to the example more suitable for the following cases:

I read and write digital and analog data at a rate of 5 kHz.  At this rate, I need read and write samples N at a time and can point single bed and wrote. I want to assure you that my output is glitchfree, then, how to grow the next N samples to the DAQ (PCI-6221) card before it has finished writing the previous samples of N?  This would ensure that at the time he was finished with the stamp of the previous, it will continue with the next buffer without missing a clock.

I can't use a blocking writing or interrogate the task when it is at the point where I managed to write the next N samples a clock or two would have passed.

Any ideas?

Hi AnthonV,

What you have described so far, I think the following example of the expedition would be a good starting point:

Help > find examples... > input and output material > DAQmx > power >

Gen CONT tension Wfm - Int Clk - no Regeneration.vi

The main idea is to define the task to continue (but not to allow the regeneration of the buffer).  Data are written continuously in time loop then the task is still running, so as long as your loop may follow the generation that should do what you need.

If you have any questions about the example do not hesitate to ask.  Thanks for posting and have a great day!

    You cannot use them with the same profile, but you can copy the user profile to B.

    See here for more help: to copy a user profile

    You must be logged in as an administrator to do and you can't copy to or from the account to which you are connected.  If you want to copy the profile to the profile B, you need to be connected on that C and C must be a member of the Administrators group, you will have to create this account C if it is not already available (or use the built-in Administrator account).

  • How to publish a free and a paid version of the same application at the same time?

    After a few days of struggle, I have made some inroads and have a lite version of my application as a project on the supplier portal that I tested (and it works). I can make now any time be reviewed for publication. But I also have a full version of the same game I want to publish. When I downloaded the zip file with new bar he told me that BB ID is already in use (or something similar).

    Has anyone here released a free and a paid version of the same game? Should I get a token using an another BB ID (I just need to do for it)? and then what happens, I'll have to operate from two separate accounts (portal provider) or how it works.

    Any ideas much appreciated.

    @jussumman You can and should submit all applications under the account of a vendor.

    You receive the error message simply indicates that the Package ID is already in use. In other words, you cannot have the same exact .bar file argued that two separate applications.

    You have two options:

    1 submit a free app and have in-app purchases to sell upgrades

    2. use a different package name to the second application.

    The package ID is from the appname and signature keys. Since you use the same keys for all applications of signature you must have different package names. This will allow you to present applications separate applications under a single account.

  • How can I create delays for many digital outputs?

    I use a PXI 6537 DAQ card to produce four digital signals for each starting at a different time. In order to create this delay the appropriate number of '0' have been placed at the front of the boolean table before converting it into a digital signal. It works by creating the delay, however using this process, the delay may be discrete increments equal to 1/╔chantillonnage and my card can be up to 50 MHz, this means that I can produce only delays 20ns increments (check my calculations). For my application, I need to be able to control the time until the second nano. Delays will usually be more than 20 ns, but less than 40ns. I tried to use the entry 'to' the 'build waveform.vi' but it doesn't seem to do anything to manipulate the data. The sub VI used to create the waveform is attached. Sending the data isn't a problem. Thanks in adavnce for any suggestion.

    JS

    Hi JS.

    The 6537 allow placement of subsample edge on its i/o lines.  The best you can do is unique (like you the noticed) examples of resolution (20 ns @ 50 MHz).

    Have you looked at the SMU-6545?  It is a 200 MHz Board, which means that you will get 5 placement ns, as WELL as data delay feature which lets you place your samples with ~ 150ps resolution compared to the output clock.

    Are you having to change the location of a signal in the clock period each cycle?  Or is the position fixed by reference to the clock, but must be placed exactly?

    Thank you

    Hi, I bought an IBM Thinkpad with XP Home Edition pre-loaded in 2005 (the XP key sticker is on the bottom of the laptop), but did not receive an XP installation CD - I understand, it is a common practice.

Can you tell me where I can find the instructions how to do this please? Any help is welcome. Thank you very much.

  • How do I create that effect on this site of the day?

    Hello, I'm curious how this designer has created this bar/menu that does not appear until the scrolls to a certain point and then rest for the rest of the site. Here is the link I found on the site of the muse of the day. potterdesigns I mean the menu yellow gold bar that appears after scrolling. Also how TI disappears when scrolling back up. Thanks for any advice.

    Richard

    Hi Richard,

    The effect is created using this scroll Effects.To:

    Place the menu item or other on the page where you want it to appear.

    Go to the FX scroll pane.

    Click the check box of the application.

    Together, the original motion down to the speed you want it to appear (1 is the same speed as the scrolling of the page).

    Adjust the Position of the key to the same value as the top of your menu.

    The Final movement value 0 - it suits it to the top of the page.

  • How can I create a new all-white or all-black layer without changing the current foreground color or background?

    I need to create a filled layer of black or white.  I need to do WITHOUT changing the current foreground or background colors. So I can't use the bucket tool. The reason is that I have created these layers inside Action and the need the current colors remain unchanged.

    Here's the easiest way I found to date:

    1. Layer-> new fill layer-> solid color...  Select one of the choices other than 'None '.  In the color picker dialog box, place the code hex #fff and click OK
    2. Layer-> rasterize-> content fill
    3. Layer-> Layer Mask-> remove

    Can someone suggest a simpler method?

    You can simply create a new empty layer and then go to Edit > fill and choose either black or white

  • How can I create tables to fluid grid to specify the location of content?

    I am building a website using checkerboard to fluid so that the site is displayed correctly across different devices. I have difficulties to get the layout to work how I see it. Elements that should be showing in a tabular format are stackable instead. How can I get my correct layout?

    Tables are not conducive to fluid layouts because tables cannot resize beyond a certain point.  Thus, they do not meet all the widths of the device.  We examined workarounds in this forum.  Some are better than others but as osgood has said, everything depends on the complexity of your tables are.  In general, I try to avoid the use of all tables in fluid layouts.  If I have some tabular data, I sometimes use lists of definitions.
