DCT for Labview fpga

Hi,
I have problems based on dct for labview fpga. I get the project example from this link https://decibel.ni.com/content/docs/DOC-8202. I run the project in labview and its run succesfully. After that, I try to use a different vhdl code for the CLIP (in labview) that I get from open cores (http://opencores.org/project,dct_idct). I rewrite the fpga.vi by inserting a new vhdl code in the CLIP. When I run the project, there are no errors. However, the compressed image is not display. I check the output values from the Read from FPGA block at the host.vi and it shows zero values at all time. I try to debug, but still don't get the solution. Anyone expert please help me. Thanks in advance.

Hey Troy,
Have a look at the attached front panel design that will be compatible in FPGA.
Hopefully it helps!!

  • C API version required for LabVIEW FPGA 2011

    What is the verison of the C API that will work with LabVIEW FPGA 2011?
    Solved!
    Go to Solution.

    I would guess this one: http://www.ni.com/download/fpga-interface-c-api-2.0/2616/en/
    The version numbers appear to start with years in 2012.  This is the highest version I could find before 2012 and it was released in August of 2011.  That time coincides with the annual NI Week festivities where a large portion of the software/hardware is released.  It's a small download so it shouldn't be difficult to download and try it out.
    But, you'll still need LabVIEW for FPGA development according to this white paper: http://www.ni.com/white-paper/9036/en/

  • Xilinx version availability for labview fpga compile

    While trying to compile a Labview vi for target NI PXI 7831R, at first I didn't have
    any Xilinx compile so I asked my network guy to instal it.  Now it complains
    that it needs 10.1 when 11.5 is available.  I asked him to install the 10.1 and
    he did but it isn't available to the NI FPGA compile worker.  How do I solve
    this?
    thanks

    Hi DonQuixote,
    You are correct in that the PXI 7831R requires Xilinx Compile Tools 10.1.  This is because this card has a Vertex II chip.  You can read more about Xilinx requirements here: http://ae.natinst.com/public.nsf/webPreview/A4B20D58C051DFB386257A56007BB0B2?OpenDocument .
    Have you uninstalled version 11.5?  What version of LabVIEW do you have?  Are you recieving an error or some other message?  If so, please post a screenshot.  
    Thanks!

  • How do I file Bug Report? Labview FPGA

    I'm not sure if this is a software bug or what, but I'm trying to run the Analog Input example project for Labview FPGA , in "Find Examples >> Hardware Input and Output >> R Series >> Basic IO >> Analog Input - R Series".
    The thing is, it works.. mostly..  I manage to send in a sine wave, and see it.  However, every now and then, when I set teh Waveform Graph X-axis to autoscale, and change the Update Mode, every time I put it into mode Scope Chart, it freezes my computer, and I have to physically power off my computer and power it back up (which i'm not happy about).  I'm using the default settings for the example, my card is in RSE mode, input signal at 25 Hz, 4V p-p
    I doubt anyone can guess why this is happening, but is there any way to file a bug report?

    1... Adding an unrelated question to a 3-month old post is not the best way to get your questions answered.
    Start your own thread next time.
    2... The example works fine for me.  The EQUALS function works just fine for strings.  Be aware of some things, though:
    Case matters.  If you want to ignore case, then uppercase both strings (or lowercase them) before comparing. 
    Length matters "X" is not the same as "X ". "123" is not the same as "1234".

  • Labview FPGA for beginners.

    Hello.
    I have no idea what labview is and how to work with this. I have had some experience with Xilinx 12.1 EDK (microblaze and VHDL).
    I tried to install labview and labview fpga module. It asked for some drivers and I continued, the program said that it will ask for the drivers later.
    But, beside that, do you have any training flow to suggest? Should I start with labview or is it not necessary? After that, should I start with CVI or FPGA? I am confused. Any help is welcomed!
    Thanks,
    Bill.

  • LabVIEW FPGA PMW modulation for L298n H-bridge

    Hello to everyone,
    I am new in LabVIEW FPGA programing and I have a couple questions, so I would be grateful if you could answer me. For my final work I have to control the speed and direction  of DC motor  using sb-RIO 9636 and H-bridge L298n. In attachments you can find scheme of the H- bridge and my program. I have conected In1(pin 5 of L298n) to digital pin 1 of the card, In2(pin 7 of L298n) to digital pin 2 of the card and changing the state of the pin I change the direction of the motor(I know that the one In should be Low and the other High so the motor can rotate  in one or the other direction). PWM(Enable pin of the L298n pin 6) I have conected to DIO3.
    PWM signal I cretaed is  shown in picture.
    My questions are:
    1.Will loop timer I used, provide that period of signal is lenght I specify in the control(for example if I put 20 000  will the period be 20000 s)?
    2. Can I vary the duty cycle changing the control Waiting (DIO3 is HIGH for a couple of us, then it sets LOW, and then all that repeats )?
    3. Earlier I thaugt that PWM signal I should send in both IN1 and IN2, and that the Enable pin is used to stop or start the motor. I tried that and the motor was rotating different speed, and I could stop or star the motor with enable pin, sending it HIGH OR LOW, but I could not change the direction of the motor. So my other option was to conect the pins as I explained at the begining.  My question is: Should I PWM conect to the enable pin, and will thah work?
    Thank you

    I found a couple of resources that deal with PWM on the FPGA and motor control - they might be helpful to reference as you look for answers to your questions.

  • Where can I find FPGA replication tool (Set RIO Device Settings.vi) for LabVIEW 2013?

    I just upgraded to LV2013SP1 and came across a VI that now is broken in my project: Set RIO Device Settings.vi (which is a part of RIOSystemReplication2009.zip). Apparently this happened in 2009 as well for a different VI in the same collection of tools (see Where-can-I-find-FPGA-replication-tool-for-labview-2009. I tried the mentioned VIs in this article but both of them are broken). Note that the Replication and Deployment (RAD) Utility does not seem to support the functionality that Set RIO Device Settings does, so I still need to use the old one. 
    Since the VI is password protected I cannot attempt to fix it. Might be something as simple as a type that changed...
    Any help appreciated!

    Hey Rob,
    This problem has already been brought to NI R&D's attention, and they are working on a fix under Corrective Action Request (CAR) 454468. Unfortunately, until they fix the problem there may not be a way to correct the problem in the near future. The CAR is set for higher priority, so a fix could come shortly.

    I'm using RTx, LabVIEW RT and LabVIEW FPGA.
    The GUI is windows based. The motion control and FPGA  are RTx based.
    Is there any way to develop device drivers for the custom hardware in RTx. For example motion controller hardware, FPGA hardware, PCI hardware.
    Is there a possibility to use custom FPGA boards to use with LabVIEW FPGA.

    CODE WARRIOR Hello. I believe this question was answered in a previous post. Please let us know if you have any new questioins or if you need some clarification.
    You are able to develop device drivers for your custom hardware using the NI Measurement Hardware Driver Development Kit.
    However, it is not possible to use custom FPGA boards with LabVIEW FPGA. The FPGA boards have to be one of our R Series boards. Here are some links that should shed some light on the Measurement Hardware DDK.

  • Why should I adopt LABVIEW FPGA as a tool for developing my FPGA projects?

    Dear Friends, 
    Since I have started using LABVIEW FPGA, I got too many questions in my mind looking for answers! 
    1-      Does anybody can tell me “why should I adopt LABVIEW FPGA as a tool for developing my FPGA projects?”
    I mean there are many great tools in this field (e.g. Xilinx ISE, ….); what makes LABVIEW FPGA the perfect tools that can save my time and my money? 
    I’m looking for a comparison can show the following points:
    ·         The Code size and speed optimization.
    ·         Developing time.
    ·         Compiling time.
    ·         Verifying time.
    ·         Ability to developing in future.
    ·         …etc.. 2-     
    I’ve Spartan-3E kit, I’m so glad that LABVIEW support this kit; I do enjoyed programming the kit using LABVIEW FPGA, but there are too many obstacles!
    The examples come with Spartan-3E driver don't cover all peripherals on board (e.g. LAN port is not covered)! There is a declaration at NI website which is "LabVIEW FPGA drivers and examples for all on-board resources" Located at: http://digital.ni.com/express.nsf/bycode/spartan3eI don’t think that is true!
    Anyway, I will try to develop examples for the unsupported peripherals, but if the Pins of these peripherals are not defined in the UCF file, the effort is worthless! The only solution in this case is to develop VHDL code in ISE and use it in Labview FPGA using HDL node!?
    3-      I wonder if NI has any plan to add support for Processor setup in Labview FPGA (Like we do in EDK)?
    4-      I wonder if NI has any plan to develop a driver for Virtex-5 OpenSPARC Evaluation Platform ?http://www.digilentinc.com/Products/Detail.cfm?Nav​Path=2,400,599&Prod=XUPV5

    Solved!

    Thanks for your questions and I hope I can answer them appropriately
    1. LabVIEW FPGA utilizes the intuitive graphical dataflow language of LabVIEW to target FPGA technology. LabVIEW is particularly nice for FPGA programming because of its ability to represent parallelism inherent to FPGAs. It also serves as a software-like programming experience with loops and structures which has become a focus of industry lately with C-to-gates and other abstraction efforts. Here are some general comparison along the vectors you mentioned
    Code Size and speed optimization - LabVIEW FPGA is a programming language. As such, one can program badly and create designs that are too big to fit on a chip and too slow to meet timing. However, there are two main programming paradigms which you can use. The normal LabVIEW dataflow programming (meaning outside a single-cycle loop) adds registers in order to enforce dataflow and synchronization in parity with the LabVIEW model of computation. As with any abstraction, this use of registers is logic necessary to enforce LabVIEW dataflow and might not be what an expert HDL programmer would create. You trade off the simplicity of LabVIEW dataflow in this case. On the other hand, when you program inside a Single-Cycle timed loop you can achieve size and speed efficiencies comparable to many VHDL implementations. We have had many users that understand that way LabVIEW is transformed to hardware and program in such a way to create very efficient and complex systems.
    Development Time - Compared to VHDL many of our users get near infinite improvements in development time due to the fact that they do not know (nor do they have to know) VHDL or Verilog. Someone who knows LabVIEW can now reach the speeds and parallelism afforded by FPGAs without learning a new language. For harware engineers (that might actually have an alternative to LabVIEW) there are still extreme time saving aspects of LabVIEW including ready-made I/O interfaces, Simple FIFO DMA transfers, stichable IP blocks, and visualizable parallism.  I talk to many hardware engineers that are able to drastically improve development time with LabVIEW, especially since they are more knowledgable about the target hardware.
    Compilation Time - Comparable to slightly longer to due to the extra step of generating intermediate files from the LabVIEW diagram, and the increased level of hierarchy in the design to handle abstraction.
    Verification Time - One of our key development initiatives moving forward is increased debugging capabilities. Today we have the abilities to functionally simulate anything included in LabVIEW FPGA, and we recently added simluation capabilities for Imported IP through the IP Integration node on NI Labs and the ability to excite your design with simulated I/O. This functional simualation is very fast and is great for verification and quick-turn design iteration. However, we still want to provide more debugging from the timing prespective with better cycle-accurate simulation. Although significantly slower than functional simulation. Cycle-accuracy give us the next level of verification before compilation. The single cycle loop running in emulation mode is cycle accurate simluation, but we want more system level simulation moving forwrad. Finally, we have worked to import things like Xilinx chipscope (soon to be on NI Labs) for on-chip debugging, which is the final step in the verification process. In terms of verification time there are aspects (like functional simulation) that are faster than traditional methods and others that are comparable, and still other that we are continuing to refine.
    Ability to develop in the future - I am not sure what you mean here but we are certainly continuing to activiely develop on the RIO platform which includes FPGA as the key diffentiating technolgoy.  If you take a look at the NI Week keynote videos (ni.com/niweek) there is no doubt from both Day 1 and Day 2 that FPGA will be an important well maintained platform for many years to come.
    2. Apologies for the statement in the document. The sentence should read that there are example for most board resources.
    3. We do have plans to support a processor on the FPGA through LabVIEW FPGA. In fact, you will see technology on NI Labs soon that addresses this with MicroBlaze.
    4. We do not currently have plans to support any other evaluation platforms. This support was created for our counterparts in the academic space to have a platform to learn the basics of digital design on a board that many schools already have in house. We are currently foccussing on rounding out more of our off-the-shelf platform with new PCI Express R Series boards, FlexRIO with new adapter modules, cRIO with new Virtex 5 backplanes, and more.
     I hope this has anwered some of the questions you have.

  • How do I install Labview 64 bit support for the labview fpga module?

    see subject.

    Hi,
    The LabVIEW FPGA Module uses the 32-bit version of the Xilinx tools, even on the 64-bit OS.
    There is no 64 bit version of LabVIEW FPGA and you must have LabVIEW 32 bit
    installed on your 64-bit machine to use the compatible version of
    LabVIEW FPGA.
    NI LabVIEW FPGA Module will run within the 32-bit emulation layer, Windows on Windows (WOW64).

  • How can I install (download) a Labview FPGA code onto Altera FPGA chip using Labview FPGA module?

    Hi there
    Guys i'm a very new labview user (PhD student), my project is about ( design and implementation of a high speed-yet sophisticated system using Labview environment then install this project's code (using Labview FPGA module) onto Altera-made FPGA chip).
    so kindly, can any body help me in this?...is there any way to connect labview with Altera FPGA?...please anything would be said 'd be of great benifits
    thanks a lot in advance.

    as previously mentioned, labview fpga only supports national instruments targets utilizing xilinx fpgas. the hdl generated by labview fpga is encrypted and cannot be used to synthesize a design outside the labview fpga design flow. 
    however, if you must use labview for your project, it might be possible for you to design the system in labview and use one of the labview embedded modules ( http://www.ni.com/embedded )to generate c code which you can then port to systemc and compile for the altera fpga. i'm not saying it will be easy, but it should be possible.
