LV FPGA program development without hardware

I am trying to evaluate an NI FPGA solution to a control problem. I have the LV FPGA software module
through our university license, but I don't have the
hardware. I want to be able to develop a LV vi and
debug it without the hardware. But LV won't let me
create the AI, AO, etc. blocks without the hardware,
even though the FPGA example code does run with those
blocks in LV. Is there some way to work around this?

When you have the LabVIEW FPGA module installed, you should be able to target a RIO device in LabVIEW even if you don't have the hardware installed. To change targets in LabVIEW, click the Execution Target pulldown menu in the LabVIEW splash screen or got to Operate>>Switch Execution Target...
Once you are targeted to a RIO target the functions palette on the diagram will change and give you the FPGA specific functions including AI, AO, DIO, etc.

  • Using FPGA program to collect data for long time without 'gap'

    Our data collection system has a NI-PCIe 7852R card. We want to collect data at up to 10 KHz for up to 10 to 30 minutes. The data amount is too large so we have to separated them into multiple Array and save in multiple files. We do not want to loose data during the saving time. Anyone has idea on how to do it? We would appreciate your help.
    My current method:
    1 using FIFO memory, in FPGA program loop , write data from AIs to FIFO memory, after certain amount of data is written, say 2000 of it, asks a IRQ.
    2. In Host program loop, wait for IRQ, once the IRQ comes, read in FIFO data, do some processing, put the data into prelocated array, once the prelocated array is full, save it to the disk.
    So far the method is not working.
    1st, there seems never a IRQ, the wait for IRQ (invoke method) never took any time.
    2nd, the FIFO reading in the host program loop seems takes no less time than the FPGA program write same amount of data into FIFO...
    SO I have extra questions:
    1. Does the 7852R cards and its new FPGA still support IRQ?
    2. What is the reading speed of FIFO read in Host program? I thought it should be much faster than the FPGA program writing it....
    Any help will be propitiated.
    Thanks a lot

    Here is the FPGA program block
    Part of Host program block inside the loop
    Part of Running results.
       1. Some data is missing in every FIFO reading in Host program
       2. The FIFO reading in Host program takes more time than the AIs=> FIFO in the FIFO program
       3. Of cause each host loop takes more time than it takes FPGA program to get same amount of data...

  • How to See logs for custom programs from without the logviewer in NWA

    Hello Experts,
    The JavaAS developers want to see the logs for their custom programs from without the logviewer in NWA.
    Do you have any experience or know of any reference materials to instruct them on where to write their logs, and how to configure NWA to see them?
    Thanks
    Jibin.

    Hello Jibin,
    Your developers should familiarize themselves with the Logging Framework of the J2EE Engine.
    Here is the guide:
    http://help.sap.com/saphelp_nw04/helpdata/EN/a2/15ab41d60bcb46e10000000a155106/frameset.htm
    If they use the Logging Framework you would be able to access the logs through NWA.

  • Question about Java programming development

    There are five phases in java program development. They are: edit -> compile -> load -> verify -> execute
    However, every time I develops program. I only experience phase 1, phase 2 and phase 5. I always miss phase 3 and 4. When do the class loader and bytecode verifier work? How do they work?
    Second question, how the legitimate programs can execute automatically without typing command java to invoke the interpreter?

  • How to see output of a program again, without running again?

    I have run a report that updates tables and shows the output, I ran the report and on the output screen I accidently pressed ESC key so it went back to selection screen. Is there any way to go back to the output screen without running the program again?
    Thanks for your inputs.

    There is a yes and no answer for it.
    Out of the box the answer is no.
    If however, the report program developer, exported the report to memory explicitly and the developer has provided you with an option via selection-screen to retrieve it from memory and display it then yes you could retrieve it. Alternative, the ouptut could have also been spawned to a spool which you could have displayed via SP01.

  • Extension Development without Extension Builder?

    Hey,
    Is it possible to do Extension Development without Extension Builder? I'm an indie developer that needs to build a tool within Flash to help an artist that's working with me,  as such, I think the partner program is an additional cost that's a bit steep at the moment.
    I get the impression that it is possible to use Flex and the Flash builder itself to do so without the additional benefits of Extension Builder.  However, I get the impression that this is really a manual process and I'm uncertain as to how documented the process is. Has anyone explored this? Any suggestions or pointers in the right direction would be great.
    Cheers,
    Jeremy

    Hello Jeremy,
    yes you can .
    A good starting point is the video by Maria Gutierrez in the CS SDK Team blog.
    I've been using for some time the SDK only in Flash Builder, so I can assure you it's possible to accomplish the task - nevertheless, since I've got Extension Builder, it's *far* easier to code, test and debug.
    By the way, this documentation is good for you even if you don't own Extension Builder.
    Happy coding,
    Davide

  • A program developed in Visual Studio are ...

    To run the Visual Studio (Visual c ++, Visual Basic, Visual c #, etc.) in the development of the program I need the .NET Framework? Can I add a drive must have Visual Studio .NET framework? If there any .Net framework should not do that if the .NET
    framework to be driving without a development program in Visual Studio or Visual Studio without the use of the .NET framework? If you let me know.
    And Can I decompile a program developed by visual c ++? Visual Basic or Visual c # is that we know, decompile.
    Wait for a good answer.
    *** Use the Google Translator meaning may not be accurate ***

    You may be better off finding a support channel in your native language, as the question is difficult for me to understand.
    Does a computer need .NET to run Visual Studio?  Yes.  Installing Visual Studio on your computer will also install .NET
    Does a computer need .NET to run an application created in Visual Studio?  A native C++ application does not require .NET to be installed on the computer that is to run the application.  Programs created in C#, VB or C++/CLI do
    require .NET.  Normally you will use an install program to install such an appliaction
    Normally you cannot decompile C++ programs in a useful way.  C# and VB can usually be decompiled in a useful way because they contain a lot of metadata in addition to executable instructions (such as variable names and object structures). 
    C++ strips all that information from its binary files and it cannot be easily restored.

  • Using FPGA and Labview without RIO board.

    Dear Sir
    I am a student. I want to connect my own FPGA and make a program on labview and then transfer to FPGA.I do not want to buy RIO.Is it possible to work

    USB Version
    The PCIe and PXI cards you mentioned are specifically RIO.
    But you managed to program a USB-6225 with LV FPGA?  I'm not even sure there is an FPGA on there to program.  It is an M series DAQ board.

  • How can I use flex motion control VI without hardware?

    I would like to try and simulate the motion control of my system before i hook up the motion control card. But when I use the VI in flex motion contro took kit it asks for address or something and gives me an error. Can't I just simulate without hardware?

    Hello,
    The only way you can use FlexMotion without any hardware is to set it up as Open Loop Stepper Control. Otherwise, you will get errors when no encoder signal is fed back to the controller.
    Please let me know if you have any further questions.

  • ABAP program developed in one system will it run in another system.

    Hi All,
           I have a very important query.
    I know that SAP 4.7, BW 3.1 and SAP CRM 4.0 have same kenel release SAP Basis 620.(please correct me if I am wrong)
    If Kernel in these systems are same, will an ABAP program developed in one system (say SAP 4.7) also work in another system (say CRM 4) with same kernel.
    This is very important me.
    Please help.
    With Regards
    Amit

    Hi Amit,
    1. If we transport a program from R/3
       to BW or CRM,
       It will work inside BW,CRM
       Bcos the basis/abap layer is always there in such systems.
    2. However, if the program uses some tables/FMs etc,
       which are not there in the Bw/Crm,
       then it may give error. thats all.
    Regards,

  • Run sql statements in PL/Sql Developer without installing Oracle database?

    Hi all,
    I wish to ask is there any possibility to run Run sql statements in PL/Sql Developer without installing Oracle database?
    Regards.

    Hello Jimmy,
    this is the forum for the tool SQL Developer and, as the title says, *(Not for general SQL/PLSQL questions)*.
    PL/Sql Developer is not an Oracle tool, but from allound allroundautomations.
    And you need access to a database to run SQL statements. This does not need to be one installed by yourself.

  • Working on SQL Developer / pl/sql developer without installing Oracle

    HI,
    I am working on SQL Developer tool without installing oracle into my local machine.
    I just took server IP as hostname and continuing with the same/
    Now, since I donot have tns names, I am not able to use any other user other than my work related.
    like scott etc.
    could anyone let me know, is there any way that i can work on sql developer or pl/sql developer without installing oracle into local machine
    like using scott etc...
    for testing and learning purpose of self code.
    thanks in advance.

    I am working on SQL Developer tool without installing oracle into my local machine. You need an Oracle client driver - this is mandatory.
    No, you do not need a TNS alias (as the connection string can be build manually by the application and the driver).
    So SQL*Developer needs to have an OCI (Oracle Call Interface) client driver. This can be "installed" using Oracle Instant Client.
    Instant Client does not really install - to use it takes 3 basic steps:
    - download it (zip file)
    - unzip it to a directory (e.g. C:\InstantClient on Windows)
    - add to your Windows User's environment an ORACLE_HOME variable that points to this directory
    These steps should suffice in making the driver in in Instant Client available to Oracle applications. (works for me running an Oracle OCI client like <i>Mumbai</i> or Oracle's <i>SQL Data Modeler</i>).
    If you want a tnsnames.ora file, then create the file and create a new environment variable called TNS_ADMIN that refers to directory location of the file. It can use the same location as your Instant Client directory.
    PS. I assume you have an existing Oracle server to connect to.

    Hello,
    Via NWA I am not sure it is possible without logviewer, but via Portal you can if you are able to create an application with help of NWDS which will read log from OS level (need to provide path for default trace in your application) show on frontend.
    Then deploy this on portal.
