Newbie needs help on Quad encoder for cRIO 9421

Hi,
When using PCI 4451/4452, we can use the GPCTR0_UP_DOWN Signal and input this signal on the DIO6 pin; this general-purpose counter 0 counts down when the pin is at a logic low and counts up when it is at a logic high.
If we are now using cRIO 9421, how do we achieve both the count up and count down capability which can be easily done using DAQmx?
Thanks thanks!
-Mr Bing

Mr. Bing,
You can do the UP/DOWN counting programatically. You can modify the examples in this folder for your application C:\Program Files\National Instruments\LabVIEW 7.1\examples\FPGA\Counters\Event Counters. To count UP you can increament as you get the events and to count DOWN you can intialize a numeric control and decreament the value as you get the events.

  • Crypto newb: Need help with encrypting data for offline Swing app

    Hi all,
    I'm VERY new to cryptography. Can somebody point me in the right direction? I've created a Swing application that is intended to be used offline (no network connections are established by the app). I need to export XML files from this application, to be transported via floppy to another instance of the application on a different computer for import. The information is sensitive and must be encrypted!
    I started looking into AES and using asymmetric ciphers (public/private key encryption). But then I realized that if Jane is exporting a file for Bob to view, she won't have access to Bob's public key (no network access). Ugghh!
    I noticed another solution in this forum where the person suggested using password encryption. It was an old post and I think it used DES. Anyway, password encryption doesn't seem too secure.
    So, I thought I'd create a symmetic key (correct term?) once, store it in the program directory, and distribute it with the application installer. That way, everyone would have the same key and would be able to encrypt/decrypt each others files. Right? Err... I'm not sure.
    Like I said, I'm a newb at crypto. If someone could suggest the best/most secure way to accomplish this, I would be eternally grateful.
    PLEASE HELP!!! :-D
    Thanks in advance.

    Sorry, Grant. I must've posted that last one just
    after your response. I was intending the message to
    be for Anand. Heh - you have no idea how many times I've done the same thing. It's an artifact of the asynchronous nature of message boards.
    Your response is very helpful. Out of
    curiosity, does my last post provide any more insight
    that would change your mind? Or do you still believe
    that using password encryption and letting the user
    choose/provide the password is the best solution?Well, as you noted, giving everyone two sets of keypairs is semantically equivalent to giving everyone a single symmetric key. And, as I've noted, it's completely INsecure - everyone who gets access to an install disk, either legitimately or no, can read every transmission your app makes forever after. Cryptographically speaking, this is Not A Good Thing.
    The advantage of PBE is that it's easy for your users to exchange keys when their machines can't see each other. The real key here is that your app, if you really want it to be secure, MUST allow/require that transmission between Alice and Bob use a different key than that between Alice and Carlos or Bob and Carlos - otherwise, if Eve compromises any user of your software, ALL users are compromised.
    I'd go with PBE, just because other alternatives are painful for your end users. You could use generated KeyPairs, for example, if you provide a means for users to exchange public keys. If you display Bob's public key in encoded, String-able form, then Bob can either email that to Alice or read it off to her over the phone. Into your app Alice loads/types in that public key, and the app now knows how to secure communications with Bob.
    Public keys are large, though, and people screw them up typing them in. And many users have TERRIBLE key discipline - if Bob loses access to his private key, he can't read anything Alice sends. And if his private key is readable on some public shared folder (which happens with a totally-frightening regularity), then we're back to no security at all.
    Use one of the triple-DES PBE Ciphers, and get on with making your app do what you really want it to do, would be my advice. (Free advice, of course, being worth every penny you pay!)
    Once again, thanks a bunch!Glad to help.

  • Newbie needs help: Authorware Web Player for Intel Mac OS X

    Hi guys,
    Complete newbie here in need of assistance please.
    I am using a Intel MacBook Pro 3.1 (early 2007) running Leopard OSX 10.5.8
    Have paid to do basic computer Microsoft Office course via net. College still uses MS 2003 and so I bought Office for Mac 04 as I was told all
    I needed to be able to do this course was to be able to open office docs via email.
    Have just received the course book and page 2 tells me to download Macromedia Flash and Authorware Web Players 5 and 7.
    Flash loads without a glitch. Went to Adobe-Downloads-Web Players page, scrolled down to Authorware player which lists both a compact and a complete version of Web Player 7 for OS X on Safari. But here's the kicker - it specifically states for Power PCs. I tried to download it anyway and
    of course it will not load. So I am apparently up the proverbial creek as far as the course goes.
    So my question is this: Has Adobe just wiped its hands of all mac users of this app once Apple changed to the Intel architecture?
    Or does anyone know of a work around or another app that can help me out of this problem?
    Any help or advice would be greatly appreciated as I am supposed to have started this course and unbelievably cannot get past page 2!
    Cheers and thanx in advance
    Yours
    Micki

      Hi everyone,
    Just thought I would give you an update on my problem. I was contacted by the lovely Matt from Adobe customer care, who was right on the ball as far as accessing my problem and was as helpful as can be. I just thought I would post his reply to my email to let everyone here know that Adobe do have a customer care line and people there to help us.
    From Matthew:
    Hello bmw14,
    First, if you send me your phone number, I can call you directly to try to resolve your issue more quickly.
    With regards to the problems you’re having, the course book is probably indicating these older Flash and Authorware Player versions simply because they were contemporary when the book was authored. The Player teams put a lot of work into ensuring that new versions can play any content that worked in the previous versions. So my recommendation is to uninstall any older versions, and just install the most recent versions of the players. These should be capable of playing any content that was authored for use by players 5 & 7 ,etc.
    Let me know if this helps, or if you’d like a call, or if we should consider the problem solved.
    Sincerely,
    Matthew

  • MacBook - Newbie: Need help on printing wirelessly to XP shared printer

    MacBook - Newbie: Need help on printing to XP shared printer
    Bear with me please. I read tons of articles on this but somehow as a newbie to MAC (girlfriends sick daughter), I am missing something. 10.5.2
    Currently, she can print directly if we plug in the HP Deskjet printer directly via USB to the MACBook. No problem.
    When we first got the MACBOOK I tried setting up the MACBOOK wirelessly to recognize the workgroup where the printer was attached via USB to the Windows XP PC. However it printed out garbage since I did not know there was a difference between XP printing and MAC (Gutenberg/gimp printing/drivers).
    Now I know there is a difference.
    But in reading various instructions, I no longer can find how to connect the MAC to the Windows workgroup. Note we do have a printer set up currently as USB-HP Deskjet on the Macbook (not sure I need to delete it yet).
    I went to System Preferences on MACBOOK and clicked on printers, more printers. In the drop down box was CANON, APPLETALK, IP HP printing and Firewire. There was no WINDOWS selection as I saw in other online web instructions.
    So not sure how to proceed to find a way to:
    1. Connect to Windows workgroup (click on what exactly), step by step please!!
    2. Add correct HP Deskjet 5490 printer (perhaps there is one with Gutenberg or perhaps I need Gutenprint-really not sure what I am talking about)
    Thanks so much in advance. Fiancé's kid has had her cancer recur in a different place and someone was nice enough to buy her a MACBOOK as a gift.
    Sincerely
    Peter

  • Need help choosing optimal hardware for a laptop that will run AE CS5

    BACKGROUND INFO (Questions listed below)
    I need some help figuring out the best hardware configuration for a new laptop. I’m a student at a design school and I will be using the laptop to mainly run After Effects and to a lesser extent Photoshop and Illustrator. I don’t need to worry about 3D rendering software or Premier Pro. I am primarily interested in getting the best performance during editing. I am not looking for the best performance for final output. I would prefer to sacrifice final output times for better editing/interface performance.
    I will be working with standard definition content and perhaps HD up to 720p on occasion. I do not need to operate in resolutions higher than 720p. My projects are generally animation and use many sources and many layers.
    I’ve been reading up on optimal hardware configurations for CS5 but my understanding is still a little foggy and I would like to use this thread to figure out how to build the best machine for my budget. The budget is about $1400 to $1600 CANADIAN after tax.
    I DON’T need help finding the laptop. I will search for it on my own. I just need to understand the best hardware to purchase within my budget.
    I realize that it is probably impossible to buy the laptop I want with the hardware configuration I need “off the shelf”. Instead I will be looking for a good base model (~$900-$1100) and I will purchase the necessary hardware upgrades separately. I will not be purchasing a Mac.
    Right now I’m thinking of a machine built something like this:
    - 15”-16” screen (17” models are too big/heavy)
    - Mid to high end i5 processor OR entry level i7 quad core
    - 8GB RAM (I would go to 12GB, but it’s hard to find a 15”-16” laptop with 3 memory slots)
    - SSD to replace HDD (However, if possible, I would like a laptop with dual HDD support or swap the optical drive for another HDD. If I had access to 2 drives, I would have and HDD/SSD combo).
    - Medium/high end NVIDIA GPU to take advantage of OpenGL while editing.
    QUESTIONS
    1) Does the “Render Multiple Frames Simultaneously” option enhance general editing performance (applying filters, scrubbing through the timeline, reverting history states)? Or does it ONLY help speed up RAM previews and final output? Does it reduce the length of RAM previews?
    1b) Is this option even necessary to enable on 64bit systems? (As far as I understand it was used to solve a problem where 32bit systems/software would only recognize 4GB of RAM per instance of AE).
    1c) If I turn this option on to help with RAM previews, would I be hindering general editing performance in any way? Or does this option have basically zero drawbacks?
    2) How come “Actual CPUs that will be used” will read 0 even if the sum total of RAM assigned to the CPUs plus the RAM reserved for other applications is less than the total available system RAM (on a 64bit system)? For example, I currently have 4GB RAM and 2 installed CPUs. I have 1.5GB reserved for other programs and when I set 0.75GB per CPU both CPUs are used. However when I set 1GB per CPU then 0 CPUs are used, even though the total RAM adds up to only 3.5GB.
    CPU
    3.) Considering the fact that I am more concerned with smooth performance while editing rather than final output speeds, would it be better to get a dual core i5 clocked around 2.5 or a quad core i7 clocked around 1.8?
    4.) What is the difference between an i3 and an i5 processor even if they are clocked at the same speed? How does an i5 460M compare on the grand scheme of things?
    RAM
    6.) Should the quantity of RAM that I get (8GB vs 12GB) be based on the number of cores in my CPU? If so, how should I be calculating optimal RAM based on # of cores. Should I also be counting threads, or just actual physical cores?
    STORAGE/SWAP
    7.) Should I replace the HDD with an SSD? I'm looking for snappy interface performance while editing. I would think that if the RAM fills up it would be best to have the SSD for scratch/cache.
    8.) What performance benchmarks are most important when considering an SSD for After Effects? (4k writes? IOs per second? Max read/write?)
    9.) I can afford the OCZ Vertex2 120GB SSD. Would this be a good choice if an SSD is recommended?
    10.) Would it be better to have 8GB of RAM and an SSD, or 12GB of RAM and an HDD? Explain why.
    GPU
    10.) After Effects utilizes OpenGL to enhance editing performance. I will not really be using Premier Pro, so catering to the CUDA Mercury Engine is not a concern. Do high end gaming cards provide significant gains in OpenGL performance? Or do OpenGL performance gains taper off around the mid-range GPUs? (i.e. can you justify buying a high end GTX 260M graphics card for enhanced editing performance versus an "entry level" dedicated card like the 310M?)
    11.) What hardware specs are most important when considering a GPU for editing performance in AE? (Memory size? # of Pixel shaders? Core speed? Shader speed?)
    Thanks so much for any answers you can offer to these questions.

    Please make sure that you've read through this page and what it points to.
    > 1) Does the “Render Multiple Frames Simultaneously” option
    enhance general editing performance (applying filters, scrubbing through
    the timeline, reverting history states)? Or does it ONLY help speed up
    RAM previews and final output? Does it reduce the length of RAM
    previews?
    It only increases rendering speed for RAM previews and rendering for final output. In After Effects CS5, it doesn't decrease the length of RAM previews. (In CS4, it does.)
    1b) Is this option even necessary to enable on 64bit
    systems? (As far as I understand it was used to solve a problem where
    32bit systems/software would only recognize 4GB of RAM per instance of
    AE).
    You misunderstood. Yes, it's still relevant on 64-bit computers. Moreso, in a way. (I'd rather not spend my entire Sunday writing out detailed answers to satisfy idle curiosity, so I'm not going to give all the technical detail to that answer.)
    > 1c) If I turn this option on to help with RAM previews,
    would I be hindering general editing performance in any way? Or does
    this option have basically zero drawbacks?
    It takes a small but nonzero time for the background processes to start up when they need to be used and shut down when they're done. And as they sit waiting, they take up a little bit of memory. So, it's not exactly correct to say that there are no downsides to leaving it on. But it's close. I leave it on.
    > 2) How come “Actual CPUs that will be used” will read 0 even
    if the sum total of RAM assigned to the CPUs plus the RAM reserved for
    other applications is less than the total available system RAM (on a
    64bit system)? For example, I currently have 4GB RAM and 2 installed
    CPUs. I have 1.5GB reserved for other programs and when I set 0.75GB per
    CPU both CPUs are used. However when I set 1GB per CPU then 0 CPUs are
    used, even though the total RAM adds up to only 3.5GB.
    4GB - 1.5GB for other software leaves 2.5 GB for After Effects.
    If you have 1GB assigned per background CPU, then the foreground takes 1.2x that = 1.2GB. That leaves 1.3GB for background processes, which is enough for one background process. There's no point in starting only one background process to do rendering, so it doesn't bother. (Note: When background processes are rendering, the foreground process isn't rendering.)
    > 3.) Considering the fact that I am more concerned with
    smooth performance while editing rather than final output speeds, would
    it be better to get a dual core i5 clocked around 2.5 or a quad core i7
    clocked around 1.8?
    Get the quad-core. That gives you a greater total number of cycles. And After Effects works very well with mutliple processors, even beyond Render Multiple Frames Simultaneously multiprocessing. An entirely unrelated sort of multiprocessing (multithreading) spreads work out to multiple processors.
    > 6.) Should the quantity of RAM that I get (8GB vs 12GB) be based on the number of cores in my CPU? If
    so, how should I be calculating optimal RAM based on # of cores. Should
    I also be counting threads, or just actual physical cores?
    The optimum amount is the amount that you can cram into the computer. I'm not kidding. Spend your budget on RAM until you have 4GB installed per processor (and I'm counting the virtual processors due to hyperthreading). If you have a quad-core, that's 8 CPUs with hyperthreading, so the optimum amount of RAM installed is 32GB. You can work with less, but you did ask about optimum. For HD work (i.e., 1920 pixels across), you're OK with more like 3GB installed per CPU. That's what I have at home: 24GB in a quad-core. You're going to assign 2/3 or so of the RAM to After Effects, so 3GB installed per CPU is 2GB per core for HD work in After Effects.
    > 10.) Would it be better to have 8GB of RAM and an SSD, or 12GB of RAM and an HDD? Explain why.
    12GB of RAM. Because After Effects likes RAM. (If you're thinking of deliberatly using virtual memory to swap memory to the hard disk, don't. That's a performance killer.)
    > 10.) After Effects utilizes OpenGL to enhance editing performance.
    Not really. If you're on a limited budget, don't even think about the GPU until you've already got the most RAM, the fastest CPUs, the largest number of CPUs, two fast hard disks, and a couple of good monitors. Then, and only then, should you even consider getting soemthing beyond a non-stock graphics card. Yes, OpenGL can be used to accelerate some things, but that's only for the low-fidelity preview renderer. (Pardon the bluntness, but I want to make sure that you heed this.)

  • DVD Studio Pro Newbie Needs Help!

    I have a presentation deadline approaching and I need help desperately. I created my presentation using Keynote 3 (800*600 slides) and exported it to a Quicktime movie using H.264 compression at 29.97 fps (high quality settings). I then proceeded to use iDVD 6 and imported the Quicktime movie and created a simple menu using the templates provided.
    I saved the entire project as a disk image and used the DVD player to check the disk image file. The quality of the DVD disk image file looked nothing like the original Quicktime movie. The images and text looked blurry and unprofessional.
    I've spend quite some time on the iDVD and Keynote discussion forums and can't find a solution to my problem. The conclusion I've come is that the mpeg-2 encoder that iDVD 6 uses is problematic.
    I don't want to start using DVD Studio Pro but I will in order to preserve the quality of my original Keynote presentation. So here are my questions...thank you in advance for your help guys....I really need it:
    - I plan on playing the DVD on a 42" Plasma display at a sales office and also distributing it to potential buyers. Are my Keynote export settings optimal for iDVD use? Should I be using H.264 @ 29.97?
    - If I must use DVDSP then what export/compression settings should I use in Keynote to preserve the quality? Keynote doesn't give me an option to use mpeg-2. I have ffmpegX so I can encode different formats...just need to know the correct one.
    - Keynote exports separate audio and video files. I combined them using Quicktime. Is it possible to use the combined file in DVDSP or do they need to be separate.
    Thanks for taking the time to read this post. Any help would be greatly appreciated. Also, if you have any reading material pertaining to this matter please provide link.
    ~Eddie~
    PowerBook G4   Mac OS X (10.4.5)  

    You can use a mov file that contains both audio and video. DVD Studio Pro will compress the mov itself. I am not overly familiar with the codec H.264 but either way its a codec that compresses the video, and if I am right that codec is used for compressing video to web based file sizes, which means heavy compression. When I create DVD material I use M2V format which is what DVD SP wants anyways so it cuts time and drive space in half. If you export an mov and import it into DVD SP, DVD SP compresses the file again which is M2V. Now you have two files, with twice the compression time. When creating M2V the only thing that you need o be aware of is the bit rate, which needs to be adjusted pending the duration of the video. Use 29.97 if you are NTSC and full frame rate, which you should be.
    If you can not create an M2V file with associated aiff audio file, than export your QT file as uncompressed or as a QT Movie. The file itself will be huge but DVD SP will compress it properly.
    I hope this helps

  • Newbie needs help with Flex app

    Hi there. I am very new to Flex and also fairly new to
    programming although I do have a little experience.
    I am trying to create an app which stores code snippets or
    common text I tend to use every day in my documents and emails.
    So basically I need help on a design level. I can refer to
    the developer's manual for exact instructions for commands, but I
    need to know what to code first.
    The app will consist of:
    -a tree directory structure where I can create groups.
    -There will be a basic text editor where I input all my data,
    basic text formatting options (font, bullets etc) would be a bonus.
    -A search function
    -Finally it will ideally allow multiple client apps write to
    a central database file over a network
    Can anyone suggest how I should approach such a project?
    Or are there any tutorials / source files which demonstrate
    each bullet point?
    thanks.

    Hey jono,
    I'm new too. But I think I might know the right components.
    If you google any of these + flex 3 you should get some
    decent documentation
    tree - advanced dataGrid component
    basic text editor - rich text editor component
    search function - well, you're gonna need to read up on
    arrays, and arraycollection. Once you get that stuff working, you
    can write up a function to search for a string in an array.
    network functionality - HTTPService, you can dump the
    datagrid into a database, and have it load the database when you
    open up the application.
    Give these things a shot, tutorials / sources will come with
    the google searches.

  • Need help with calculator project for an assignment...

    Hi all, I please need help with my calculator project that I have to do for an assignment.
    Here is the project's specifications that I need to do"
    """Create a console calculator applicaion that:

    the arithmetic operations as well as at least five scientific operations of the
    Math class.
    -Your program must also have the ability to round a number and
    truncate it.
    -When you multiply by 2, you should not use the '*' operator to perform the
    operation.
    -Your program must also be able to reverse the sign of a number.
    * Include sufficient error checking in your program to ensure that the user
    only enters valid input. Make use of the String; Character, and other
    wrapper classes to help you.
    * Your program must be able to do conversions between decimal, octal and
    hex numbers.

    Now my question is this: How can I restrict the user to only enter 'letters' (and spaces of course) but allow NO numbers for his/her surname??You cannot restrict the user. It is a sad fact in programming that the worst bug always sits in front of the Computer.
    What you could do is checking the input string for numbers. If it contains numbers, just reprompt for the Name.
    AND you might want to ask yourself why the heck a calculator needs to know the users Name.

  • Need help buying a PC for a graphics designer.

    Hi,
    I have a user that uses a desktop maskin basically only for Photoshop. I have my eyes on the following PC but im not sure if it is good enough for working with photoshop.
    I would  appreciate all the help i can get. for exemple, should there be more CPU or a better Grapic card.
    Precision T1600
    Intel Xeon E3-1225, 3,1 GHz, Quad Core CPU
    16GB RAM
    1GB nVidia Quadro 600 (DP,DVI)

    I'm not fond of nVidia.
    Me neither. I had a NVidia card in one workstation, which I finally got to behave in Photoshop after going through...a number...of driver versions. Problems were legion: stuttering and jerky sliders, disappearing cursor, flashing tiles display, crashes, even BSOD's. But in the end I found a version that worked.
    Then I bought Lightroom 4. Sliders would take two seconds to respond, and another three to four for the display to update. Switching between two images was agony. It was totally and utterly useless.
    The other machine has an ATI 5850 and has never given me any problems. So I thought what the heck, bought an ATI 6670 card - and all the Lightroom problems went away, just like that.
    My totally unscientific conclusion is this: NVidia is for kids playing games. People doing serious work should stay with ATI.

  • Newbie needs help with MS exchange / MS Push email

    I just got an iPhone 3G a few days ago. Heretofore, all my experience has been with HTC, Motorola and Blackberry phones. As a non-technical person trying to make Pust work through my network is very confusing.
    I read the instructions / bulletins and finally made email and calendar work (sort of). It only works on WiFi and then I have to manually update mail as it does not always Push.
    Does the iPhone Push setup only work with Server 2003 / Push via WiFi? If not, can anyone give me step by step instructions on how to make it work with 3G and no WiFi?
    If possible, please be specific as I am a newbie trying to make this work for my small company.
    If I can't find a solution I'll have to get rid of this and go back to something that works.
    It seems that Apple is making it very difficult to set this phone up for Push application
    Thanks,
    Gary

    The iPhone works fine over cellular. You did mention a certificate - I am going to guess that this may be the issue.
    If you open Safari on the iPhone and connect to your OWA, do you get a warning? When you viewed the cert in IE, is it self-signed? If so you need to get it on the iPhone. The easiest way is to set up gmail or something similar on iPhone and email it to yourself.
    when it come in email your iPhone will immediately recognize it as a file that you can import it. Select it and import it, then you should be able to connect to your Outside Exchange server.

  • Need help in dynamic report for a range of year and period

    Dear all,
    I need help in creating an ALV report with dynamic columns based on the Year and period entered on the selection screen. for example if in the year we enter 2002 and period range from 10 to 12 then we should get the 3 columns display for cost(example) for period 10/2002, 11/2002 and 12/2002.
    Can anyone help me in achieving this dynamically since the user can enter the year also in intervals along with the period and data also needs to be populated in the corresponding columns.
    An example code would be of great help.

    You can do so, but you would shutdown the whole standby environment. But normally standby is used to have no or only short downtime. So a switchover to the standby DB is performed (after this standby is now running as primary), maintenance is done on the primary and then at the end another switchover back from the 'new' primary to the 'old' primary.
