Digital i/o with cards cRIO 9472 and 9421

Well, I'm whipped...

Here is my goal - I want to generate a random L.E.D. signal to one of 5 stations. I want to wait then the corresponding entry of this station to go high (proximity sensor), confirm and start all over again. I have a generator of numbers, 0 to 4, which seems to work very well I converted to a Subvi. That's where I hit the wall: MAX reads the card 9421 on a channel when I change my status, but I can't do anything with this signal in my program. MAX can generate a vertex at the 9472, but I can't get my program from one summit to the randomly generated station to start the exit process. Here's what I have so far

I know that I have to wait for the station selected for the top to this station to continue a loop. I saw the example called 'Read-write-Single_Dig-lines', but I'm much too green to understand. "There must be an easier way!

Can anyone help?

I'll KUDO in a heartbeat!

Thank you

  • Can't play CRYSIS and GEARS OF WAR on portable computer with card Nvidia 7900 GS?

    I wonder if anyone here have the chance to play two games CRYSIS and GEARS OF WAR on PC Toshiba laptop with Nvidia 7900 GS cards.

    The reason why I asked this question-> because I have 2 problems:

    (1) GEARS OF WAR first need new driver for Nvidia telling me this massage * to run Gears of War with your current hardware configuration, you must install the following software update or updates: *.

    * + NVIDIA ForceWare 163.44 driver *.

    * If you do not install this software, at some point, the game ends and your progress will be the lost.* and give me another massege when I click on play

    the massage is * this application has failed to start because xlive.dll not found. Reinstalling the application may fix this problem *.

    (2) on CRYSIS game working, but with very poor quality and a few fast breaks during playback I tried to graph affecting minimum put the same thing happen...

    I hope that someone here can give some advice on the above issues, and a suggestion for a new driver will be appreciated ;)

    see you soon

    Hello

    _ _Regarding point 1)

    Check out the www.laptopvideo2go.com site and to update the graphics driver!
    This site contains some useful nVidia drivers that can run on laptops.
    But note; pilots can be used only at your own risk!

    _ _Regarding point 2)

    Crysis needs huge resources for laptop. I think that the card Nvidia 7900 GS is not strong enough to run the game with full graphic details!
    I read on some game sites that you need a desktop PC of very high technology with that of the new series of nVidia 8600 to the smooth running of the game!

    Best regards

    Almost all of the Canon 'Vixia' line of cams are less than 1 k $. The Vixia HF G30 $1150 and it is the only model over $1 k.  Here are all the models to consumer prices.  (X XAnn, XFnnn, & XCnn series is top of the line, and of course the EOS film bodies are much more expensive.)

  • Problems with the Precision M4400 and the graphic card Nvidia quadro 770M

    I have a problem with my Precision M4400 and Nvidia Quadro 770 M. After I installed Windows 7 64 bit, I have problems with the graphics card. I get a blue screen or graphic errors. I tried several versions of the driver. In the Nvidia forum had this problem even more. Here, they told me that only a BIOS update for the graphics card to solve the problem. Update the BIOS, but I should refer by DELL. So my question is this problem with Dell is also known, and there is already an update of the BIOS to the Quadro 770 M?

    Hi all

    I have the solution by chance. I was looking for the latest drivers GeForce for Windows 7 x 64 and I read the accompanying note: http://fr.download.nvidia.com/Windows/337.88/337.88-win8-win7-notebook-release-notes.pdf
    On page 17, you can read the following note to fix: "[GeForce FX 770 M] [portable]: blocking of the blue screen occurs after Windows starts."

    Of course, GeForce FX 770 M does not exist (and never was), and it should be Quadro FX 770 M. I can bet that nVidia has corrected this famous BSOD problem in the wrong driver because always there is nothing about any "Quadro FX 770 M - fix" in the note accompanying the latest Quadro (340.52) driver.

    You try the GeForce driver above, but to install it, you may need to download an INF file modified with the addition of the ID of Quadro FX 770 M (= "NVIDIA_DEV.065C ="NVIDIA Quadro FX 770 M"). Try without the first modified INF file because the Quadro FX 770 M is listed as a compatible chip in the version of the driver GeForce 337.88 note...

    I'll try that, even though I am completely sastified with the latest driver for Quadro (feasible) (285.62) without disable Powermizer. I did not try the latest Quadro drivers again (to be honest).

    Late me know please.

    No, it has nothing to do with updates of Adobe. There is a problem with your video card driver.

  • How can I configure a port Ethernet NI9792 gateway to communicate with a cRIO CAP?

    Salvation OR engineers,

    I intend to use my gateway NI9792 in the following way:

    1. a single Ethernet port for network connection. That's how I'm developing, download the software and monitor my request through my PC in my office.

    2. the other port to communicate with a cRIO device? If so, how can I do it?

    It seems to be a stupid question, but I really couldn't work this!

  • Measurement of angular position with encoder in quadrature and NI USB 6281

    Hello.I have an application developed with labVIEW 7.1 and 6014 OR for the measurement of angular position using encoder quadrature, where are used 3 sons - one of them connected to the source, second to the OID (0 or 1) and a third to digital ground. I can't use the same application or NI USB 6281.Now connections, I would like to know how I can create a similar application in labview 2009 and how to make the relevant connections for NI USB-6281, which is a mx NI DAQ device. Please suggest. Thank you.

    I have my loan application. I understand there are big difference using LabVIEW 2009 and NI USB card, compared to the previous version I was using THE LabVIEW 7.1 and a traditional daq. The difference, I should say that wellness is both in terms of simplification of code and the accuracy of the result. I was a little surprised, showing results. Thanks a lot to JB for your time and sharing those pieces of details.

    I can well after awhile my code in the forum. Hope this helps someone like me looking for a similar application.

  • Online use of relaxation on the cDAQ-9181 with a cRIO-9401 module

    I'm trying to accomplish something very simple with the cDAQ-9181 and cRIO-9401 material: when a trigger occurs, wait 20 ms and then set some digital output lines. Reading the documentation for the cDAQ-9181 and cRIO-9401, I see that there is a trigger of PFI0; I do not see a physical entry for it, so I guess that it is implemented internally in a way. I tried to use a digital camera of entry as a trigger, but I get the error-200524 with my code. I looked if the examples, but I don't see how to do it with my gear. Help, please. Thank you. See attached png for the block diagram.


  • Can PCI 6602:How I use digital lines of the Board of Directors and at the same time to generate trains of pulses by using a meter?

    Hello!

    My problem appeared when I tried to update my traditional NOR-DAQ legacy code to DAQmx.

    I use 2 meter (meter 5 and 7 meter) on PCI-6602, to generate trains of pulses, as well as the lines of e/s digital port 0 (the form lines from 0 to 7). What I do in my request, it's that I'm starting to generate the pulse train on the output of 2 meters and after that I play with the State of digital lines.

    Traditional, it was no problem to use the meters and digital lines at the same time, everything went perfectly, but in DAQmx, is not possible.

    What's happening: I start generating train of pulses on the output of counters, no errors, but when I try to change the State of a line of digital port the generation of the pulse train is stopped. What happens when I start the task associated with the digital way.

    My question is: is it possible to create a channel on digital lines without changing the channels created for meters?

    Another thing that I managed to do with the panels 'Measurement and Automation Explorer' and Test for PCI-6602, is basically the same thing, I generate trains of pulses on the output of the 7 meter and try to start a job on the digital line, but I get an error:

    "Error-200022 occurred in test Panel.
    Possible reasons:
    Measurements: Resource requested by this task has already been reserved by another task.
    Device: Dev4
    "Terminal: PFI8.

    On the contrary if I use the counter 0 or a counter 1 to generate trains of pulses I encounter the same problem.

    What resources are used by 2 to 7 of the PCI-6602 card counters and the counters to 0 and 1 do not use?

    Thanks in advance for any answer!

    Ciprian

    After doing some real tests on this device, I found that it is a normal behavior for the jury of 6602.  This is because when you start a task digital all 32 lines are configured for digital i/o, so it replaces your meter operation.  The article below the link explains a little more on this subject.  You must start the digital task before the task of counter to use the features of both in your program.

    2 meter and above will not work correctly when you perform digital i/o on NI 6601 or 6602

    In the Photos of El Capitan how to record a double published in a separate with its own name and the ID file file?

    Only by exporting - with Photos (and iPhoto and Aperture) - you can have several versions of an image by duplicating the image (control - D), but this does not create an image file separated until you export - it creates a separate edit list in the database that applies to the original when you watch or export the photos

    Photos as it were its predecessors is a non-destructive control Digital Asset Manager (DAM) which does not any changes to files in the database but built a list of validation

  • M40X: using digital telephone line with modem internal

    [Edited by: admin August 10 05 21:19]

    Hallo nasir

    You are right. Connect the modem to a digital telephone line. As far as I know, the tension is much higher by digital line and it can damage the equipment.

    In my opinion the best solution for you is an external digital modem.

    Passing over the first set of instructions followed to create a D partition on the HARD drive, for some reason any now have only C with 130 GB so that D is not specified, no idea how to fix

    a big thank you in advance, cheers, Aleks

    Hello!

    You can determine the type of wireless network card if you check the vendor and device ID in Device Manager. Enter the two codes on this Web site and you see what WLAN car you have: http://www.pcidatabase.com/

    Regarding your question on the partitions on the HARD disk, you should look in disk management. Maybe you need to format the first partition or create an extended partition.
