Error-50352 DAQmx: How can I determine the maximum size of the buffer?

I use a card PCI-6259 with DAQmx (version 9.0.2) library and I get the error "-50352: memory cannot be allocated" whenever I try to make my record too long. Here are a few terms that I found:

1 channel of AI, 1Msample/s: 7.71 sec max

1 channel AO, 1Msample/s: 7.71 sec max

1 channel of AI, 500ksample/s: 15,4 sec max

2 channels of AI, 500ksample/s: 7.71 sec max

1 HAVE, AO, 1Msample/s 1-channel: 5.6 sec max

IF I can't acquire more 7.71 Msamples in a single task, be it in most cases, or AO. When you mix tasks HAVE and AO, this limit seems to be decreasing. This happens with a freshly started application, so I don't think that it is a question of compensation task.

What is a physical boundary with the device? (And if so, how can I determine this limit?)

My impression is that the device uses DMA to transfer samples to the system memory, which there are plenty - I can easily allocate more than 400 MB of contiguous memory in the same application.

Hi Luke,.

The amount of RAM your system installed?

What operating system do you use? If it is a 32-bit operating system, using 3 GB or increaseuserva? These parameters have a compromise: they reduce the size of the kernel virtual address space. This increases the probability of DAQmx will succeed to allocate memory but do not reach the mapping in the kernel virtual address space.

Your system has all the devices with very large memory mapped I/O beaches, such as a video card with a large amount of memory on-board? On a 32-bit operating system, this can reduce the size of the virtual address space of the nucleus by a significant amount.

  • How can I determine the RAM bus speed?

    Hello

    I installed the new 4 GB RAM replacing the previously installed 3 GB of RAM. The previous 3 GB of RAM has the 667 MHz bus speed (I found it in the user manual). The new 4 GB of RAM, the seller told me that has the 800 MHz bus speed. Now, I want to be sure that the seller does not deceive me, and he gave me the speed of 800 MHz RAM bus. How can I determine my installed RAM bus speed? My system configuration is the following:

    Windows 7 Ultimate 64 bit

    2.1 GHz Core2Duo

    4 GB OF DDR2 RAM

    Intel GMA 4500MHD

    Model: Acer Aspire 5738

    I have two modules of DDR2 soDIMM, previously, I had a 1 GB DDR2 667 MHz + a 2 GB DDR2 667 MHz RAM = 3 GB DDR2 667 MHz RAM (in my manual of the system provided by Acer)

    Now, after replacing, I have two 2 GB DDR2 800 MHz RAM = 4GBD DDR2 800 MHz RAM (as the salesman told me and I saw written in the package when he was unpacking and installation)

    How can I determine my RAM bus speed and be confirm that I really learned the 800 MHz? Please someone help me with this. Thank you.

    Four ways I see real quick:
    1 - the label on the RAM (assuming that it is there, and this truct you he has not changed it).
    2 - install the CPU-Z.  It will be listed in the memory tab.
    3 - install Belarc Advisor.  It also lists only (as well as much more information on the system.)
    4 take a look at the POSITION of the screen when the system boots - he must view RAM info.

    All the foregoing, guess however that isn't only MHz 800 RAM installed, but that the system is actuallyrunning at 800 MHz.
    Here, CPU - Z is the best choice, because it will give you the actual manufacturer for RAM; You can use it to find the specifications of the manufacturer.

  • How can you determine the absolute path to a NetStream object created dynamically?

    We strive to implement a video captioning with a freeware component, ccforflash. This requires us to provide an absolute path or relative to our NetStream. How can we determine this path in Flash CS5 AS3?

    CCforFlashCS5 documentation:

    2. objects "name and path.

    Type the name and the path.  It is the name of the instance of the object with which CCforFlashAS3 will synchronize. It must be spelled correctly, since CCforFlashAS3 queries the object with this name for the synchronization information to synchronize subtitles. The path must also be included; be compared to the CCforFlashAS3 (i.e. this.parent) component or the absolute path of the main floor of the film (root)".

    I guess I understand your problem and accepts only a great way to identify a path to something compared to doing AS3 AS2.  I'll see if I can raise the interest of someone else in your ad that is a detective better than me.

    But if I can get stoopid for one minute and suggest trying something (I would try it)... If you have access to the code where is instantiated the NetStream object, just after he is given life, assign the instance to a variable, you have in the main timeline and use this variable (and the root timeline or a 'this' - reference database for path requirement) for your CCforFlashCS5 needs.

  • How can I determine the type of image to be used before loading an image?

    I'm developing an application using VB 2005 which measures two 8-bit or 16-bit image files. When I saw the picture, I find that I have to set the type of image the image buffer before playback of the image in it. For example, if I read a 16-bit image in a buffer of 8 bits, the image is truncated. I guess I could read the image in a 16-bit buffer and retype it if the pixel values are less than 255.

    Is there a better way to do it? Can I determine the number of bits of an image before loading in a buffer?

    Thank you!

    Hi Steverino,

    Olivia is incorrect... VDM has a function called GetFileInfo which does just what you want. It only reads the header of the image but does not load the entire image in memory. It will give you various properties such as the bit depth.

    I think that on the new .NET support, there can exist here: NationalInstruments.Vision.Analysis.Algorithms.GetFileInformation.

    Thanks to the ICB and our legacy of .NET support, it's probably a similar name.

    There is no API for this setting. If you see as important, you could offer it to your own parameters, otherwise just go with the standard.

  • How can I determine the specified VO is updated or not?

    All the

    There are several of your in my AM and the method this.getDBTransaction () .isDirty () returns the true value once the VO has changed but not validation. How can I understand the specific vo to see if it is replaced. I want to add some customization to the specific vo logic in the beforeCommit() method in AM.

    Gerry,

    There is no direct way to do this for a VO.

    For VO lines, however, you can call getEntities() and loops through the entities returned asking them getEntityState().

  • How can I increase the buffer size of the StationID variable

    I'm reading the variable string StationID in TestStand, which holds the name of the computer. Currently, it truncates to 14 characters.

    How can I increase the size?

    Thanks in advance.

    Hi WDLV,

    What version of TestStand do you use?  I tried this in 3.5, 4.0 and 4.2 and verified that the StationID (RunState.Root.Locals.StationInfo.StationID) was able to contain a name more than 14 characters.  You use this method to access the stationID, or something else?  Also, you see this with any order, or just an individual?

  • How can I determine the best order to execute my butterworth filter at?

    I'm low-pass filtering of a signal that has been sampled at 200 Hz through a butterworth of 40 Hz. I need determine the optimal filter order. How can I create a quantitative comparison of the effects of filter butterworth on frequencies above 40 Hz according to various order?

    I tried using the FFT to create a graph in the space of the frequencies, but do not know how to proceed. Any help would be greatly appreciated. I want to compare what the path immediately before and immediately after the butterworth filter.

    Also there is another way to read in a column of numbers from a text file without using reading the measurement file Express VI?

    Ok

    Standard of comparison filters for roll-off slope is to consider the report of the frequencies to two different attenuations.  In general, this is done to-3dB and something else by example-60 dB.  You have your data plotted in a linear way. Maybe just by looking at the f(@0.75)/f(@0.25 report) would be sufficient for your needs.  Looking at your images: order 2 f(@0.75) ~ = 38.  f(@0.25) ~ = 60. Ratio = 1.58. Ratio of the order of 10 is 39/42 = 0.93.  If you want more big numbers for best performance use inverses.

  • How can I determine the position of the mouse in a 2D image control

    I have an app where I would like the user to be able to interact with objects in a 2D image control with the mouse.  To do this, I need to translate between the screen coordinates, which are transmitted with the events of mouse and in the control of 2D image.

    The problem that I am running is that I can't find a way to determine the screen coordinates of the top left corner of the drawing/client of the 2D image control area.  I tried to use the 'Position' of the image control property, but this results in a mismatch because of the difference between the upper-left corner of the image control (including the label, etc.) and the upper left corner of the drawing area.  See attached VI.

    Does anyone know how to get the coordinate of the screen from the corner of the drawing of the control of the photo area?

    I tend to use the mouse in the image control property to get the position.  Deals with things like the passage of origin for you.

  • How can I determine the configuration of TLS/SSL in Firefox ver 38?

    I received the following message (partially shown) when I tried to connect to a particular Web site.

    The secure connection failed
    An error occurred during a connection to xxxxxx.xxx. Cannot communicate securely with counterpart: no common encryption algorithm. (Error code: ssl_error_no_cypher_overlap).
    The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

    I tried the MS IE browser and had a similar view. I checked the security settings on IE, added TLS 1.1 and 1.2 of TLS selections and solved my problem on the Internet Explorer browser.

    So I wanted to check the settings for TLS/SSL on Firefox but couldn't find where they were selected. I thought that they used to be under Tools/Options. Where can I go to check them?

    You can post a link to a page accessible to the public (i.e. no authentication or signature required)?

    The site may attempt to return to a lower version of TLS in a way that is no longer allowed in current versions or maybe use a deprecated suite of encryption.

    You can open the topic: config page through the address bar and use the search bar to locate this pref:

    • Security.TLS.insecure_fallback_hosts

    You can double-click the line to edit the prefs and add the complete field to the value of this preference.
    If there are already websites (domains) in this list, then add a comma and the new domain (without space).
    There should be only areas separated by a comma in the column value (example.com,www.example.com).

    If this help you can contact this Web site and ask them to look into this and update their security.
