County of the edges of the AI of signals with the module 9221

Hello

I'm counting the edges of a signal to HAVE acquired with a module 9221 on a cDAQ. The average rate is about 1 kHz.

I'm with 10 kHz signal acquisition, but do not get the right amount of edges.

Is there a solution for this problem. I know, of course, it would be easier to use a CTR-modul but my signals does not match the plug.

Thanks for any help

Hi Yves,

There is a method to count planking of an analog input. See the link

I hope this will help you.

    Thank you for your attention,

    Thank tzander reminding me the idea. Method of cascades is not good for me because all of the kernel code is written by Native. If I change the channel to QString, I need to change a lot of codes.

    Solution is below.

    While (access (rawfilename, F_OK)! = - 1) {}
    rawfilenamecount ++;
    sprintf (format, RawFileName, rawfilenamecount);
    fprintf (stderr, "file exists");

  • How can I measure the output of a sensor pwm ultrasound using the module or 9403

    How can I measure the output of a sensor pwm ultrasound using the module or 9403

    Khalil,

    When you say 'measure' the PWM signal, exactly what to tell you?

    You're looking to measure the frequency or cycle of the signal function? You count the edges of the PWM output increase? Looking to control the waveform?

    With reconfigurable FPGA hardware, it is up to the user to define the function of the physical i/o on the FPGA chip. By connecting the signals as Adam suggests your digital pulse will be brought to the cRIO. In your FPGA program, you define the function. You can set a base counter or transfer digital data from single point to welcome you cRIO for floating-point more complex treatment. Example FPGA programs are located in the http://www.ni.com/IPnet.

    Hope this helps, please post any additional questions.

    «We are implementing a new extension API, called WebExtensions...» »

    The infrastructure of the current extensions will be gone and with it will have the advantage of current extensibility that Firefox had more Chrome and Opera. Kinda like the rating "fascism" for "communism".

  • How can I DISABLE the module "signature" when I want TO use an older add-on?

    I the MAGNIFICENT Add on 1 - ClickWeather and now has a message on the 'signature' module Now... I DON'T want to use a product of INFERIOR quality such as suggested in the name of the add - on.

    I would use the add-on that I already have on my Firefox, 1-ClickWeather. So, how can I disable the 'signature' on an individual add-on module? It is said to "Act with caution", but it does not show Me the details of my time. I reinstalled the add-on, but it does not yet record my position.

    Yes, I KNOW it is no longer supported, but has always worked until this past Saturday. It was abandoned several years ago but was kept alive by a single poster whose comments have disappeared. I have the add-on on my computer. I continued to update the continuous Firefox updates. Now, I want to again but there's this ridiculous thing on the module "signature" and «proceed with caution...» »

    You cannot delete the warning, but in 42 Firefox extension should always work.

  • Impossible to install the modules that are hosted outside of AMO

    I can't install any add-on that is hosted outside of AMO, in Firefox for Android 40.0.3, nor in Firefox Beta for Android 41.

    What I think should happen: I have download the file as signed (it records to SD card), then open it with Firefox and Firefox should ask me if I want to install this module.

    What is really happening: an add-on is downloaded, but when I open it is file as with Firefox - nothing happens. Firefox comes to shows me a blank screen (see the screenshot).

    My friend has this problem too.

    Looks like a regression bug (because I could install add-ons hosted out of AMO without any problems in previous versions), but I'm not entirely sure.

    So my question is: should I file a bug on Bugzilla or is it possible to install the modules hosted outside of AMO to Firefox for Android and it's just me something wrong?

    My phone has Android v2.3.5.

    UPDATE: apparently, I can not install the modules of local files, but can do some some sites. My module (I have problem with) is hosted on Github, and I can't install it for whatever reason.

    Update 2: it seems that modules can be installed from Github if she is not just a file (because Github changed Content-Disposition of at least some types of raw file of 'inline' to 'attachment'), but a binary attachment to a "news release".

    Apparently, I found a work around for this problem, so that this issue does not require a response more.

  • How can I recover the modules and their data from a failed HARD drive (the lost BONE areas, but data files are readable)?

    The HARD drive that was my OS (Windows XP Pro SP3) failed and lost quite a few areas which are essential for the operating system running. Other data is still readable. A got another HARD drive and installed Windows XP SP2, Firefox and other programs. I was able to retrieve the bookmarks, security certificates, and other profile information using the information found in bandages.

    None of them addressed how do to recover the modules or their data. Specifically, there are several large, elegant scripts that took months to develop and customize.

    Articles related to migration and other do not work for me because they require the old copy of FF is functional, that is not because the OS on this HARD drive is damaged. Is it possible to recover these data, similar (or not) about how I could get the other profile info?

    Have you copied the entire folder C:\Documents and Settings\username \Application Data\Mozilla\Firefox\ on the old drive?
    If this is not the case, can you?
    If so, make a copy and save this folder just in case.

    If so, you could replace this folder on the new facility by \Profiles\ [with your profiles inside] folder and the profiles.ini file [delete all other files / folders that may also be in the folder "Firefox"] -and then replace with the same folder named from the old failed drive. Note that you will lose what you already have with the new installation / profile!
    Your profile folder contains all your personal data and customizations, including looking for plugins, themes, extensions and their data / customizations - but no plugins.
    But if the user logon name is different on the new facility that the former, any extension that uses an absolute path to the file in its prefs will be problems. Easily rectified, by changing the path to the file in the file prefs, js - keep the brake line formatting intact. The extensions created after the era of Firefox 2.0 or 3.0, due to changes in the 'rules' for creating extensions usually are not a problem, but some real old extensions that need only "minor" since that time can still use absolute paths - even though I have not seen myself since Firefox Firefox 3.6 or 4.0.

    View instead of 'Modules' I mentioned the 4 types of 'Modules' separately - Plugins are seen as 'Add-ons', but they are not installed in the profile [except those mislabelled as a "plugin", when they are installed via an XPI file], but rather in the operating system where Firefox 'find' through the registry.

    Note: Migration articles can tell you do not re - use the prefs.js file, due to an issue that I feel is easily fixed with a little inspection and editing. I think you can manage that my perception is that you have a small shovel in your tool box, if you encounter a problem you are able to do a little digging and fixing problems with the paths to files - once you have been warned.

    Overall, if you go Firefox 35 35 or even Firefox 34 to 35, I don't think you will run in all the problems that you can not handle [that I cross my fingers and "hope" that I'm not on what it is obvious].

    With regard to the recovery of the 'data' for individual extensions - there are many ways that extension developers used to store their data and pref. The original way should save in prefs.js or their own file RDF in the profile folder. While Firefox has been developed more, developers started using their own files in the profile folder. And because Mozilla has started using sqlite database files in Firefox 3.0, Mozilla extended their own use of sqlite, as have extension developers.
    Elegant uses the file stylish.sqlite to store 'styles', but something in the back of my mine tells me that 'the index' maybe not in this file with the data. But then again, I can be confusing myself a question I had with GreaseMonkey awhile back where I copied the gm_scripts folder in a new profile and with already installed GreaseMonkey but with no script. These GM scripts worked, but I could not see them or modify them - they do not appear in the user GM extension interface window in Firefox.

    Hello. I use 31.3.0. and it hangs in safe mode or in normal mode under one of these conditions: - in 4 minutes - after sending, - add-ons - to help restart/help with opening modules removed Manager. I have reinstalled twice. Yosemite in a day. So I can't install viewabout and am unable to disable the Add-ons before crashing. I don't remember installing add-ons, but they seem to be a common source of accidents, so maybe I did. But... can't watch. Can I worry please someone for a suggestion? Thanks for any help!

    Hi rbfreemontana, I'm not very familiar with Thunderbird crashes, or the Mac platform, but I noticed that, just before the crash that Thunderbird tried to run this called 'fbplugin' and there is a corresponding bug report referring to the "Facebook Photo Uploader' of problems on Yosemite. You will find this add-on and either disable or delete it?

  • The add-on works with Firefox 33.0 on a single computer, but on a different computer, Firefox 33.0 indicates that the module is not compatible.

    I have a laptop and a desktop computer. Both are HP and both have recently been updated with the latest version of 8.1 and 33.0 Firefox Windows. On the desktop, Norton Toolbar still works fine. However, on the laptop, Norton Toolbar is disabled and the modules Web page has a message saying that Norton Toolbar is not compatible with Firefox 33.0. Why is this compatible on my desk, but not on my laptop?

    Hello, according to norton toolbar is already compatible with firefox versions, including the current version. Please run the norton utility liveupdate repeatedly & until all components are up-to-date. Additionally, make sure that the toolbar is enabled under firefox > addons > extension thereafter.

  • Where is the help on the topic: "restart with disabled modules.

    In aid of the menu choice "restart with disabled modules" is trying to find out what would be the consequences of this command, but I can't get any result on this SPECIFIC command. If I try, I definitely will disable my Add - ons?

    I have to ask this question because I've had nothing but problems with Mozilla Addons lately, especially the themes.

    I'm tired of Firefox

    Basically what the restart with disabled modules is it closes your Firefox and them it opens in safe mode, which is a temporary mode where all add-ons are disabled, and the settings are set to their default values. It helps you to be able to test and see if your question is without third-party variable. Then, when you close and restart firefox, it starts as before without Add-ons.

    Questions to troubleshoot Firefox in Safe Mode is an article that explains a bit more.
