• 2651 a conversion of TSP Script for LabVIEW

  Hello

  I have a problem on the conversion of all TSP scripts that contain functions and appeal for the end loops. I'm new to the TSP with models of trigger scripts. I used the Script Builder (TSB) Test tool and am able to run any TSP and generate raw data, but I don't seem able to convert most of the codes in the command of LabVIEW VISA or loader LV TSP TSP and run it to generate data... I can't find any tutorial or examples how to do it.

  Let's say that... Use the example of KE2651A_Fast_ADC_Usage.tsp (pulse) and I'll just focus on the portion of function CapturePulseV (pulseWidth, pulseLimit, pulseLevel, numPulses). I have seen a few examples of LV that says loadscript myscript and close on endscript.  I did a lot of different approaches, and I kept getting errors in particular the print function that I am not able to generate data through LV by to read the data in the buffer to inside the instrument. Some approaches, I have had no errors but no data... Some approaches, I got error-285.

  The part of the code TSP pulse that works in TSB is here (I'm not including loadscript and endscript) and what is the RIGHT way to modify the code for LabVIEW and run it and obtain data? Thank you:

  function CapturePulseV(pulseLevel, pulseWidth, pulseLimit, numPulses)
      if (numPulses == nil) then numPulses = 1 end

  I finally solved it myself! I first create support shell, according to the documents, but the problem was with functions of scripts but I solved by introducing VISA separate, feature writing and THEN retrieve the data from the instrument directly by VISA buffer read more. I did TSP_Function Script Loader that allows simply copy/paste codes teaspoon (any * .tsp) of: TSB program or incorporated into this type of function and loader.vi, name (parameters), defined by its own pasted script then it will generate RAW files directly in the array of strings that can be broken into pieces or restructured into what you want as for the graphics, etc..

  That's all I really need to do, I can do codes of tsp in LV and get the data off of it easily via the function defined. Now, this Loader.VI behaves in the same way that TSB keithley-made program I use.

  Here I add Loader.vi Script TSP_Function (in LV 2011 +).

• Is there a way to determine the equivalent ANSI C code of a Labview project?

  I'm a complete newbie to Labview.  I have this quite complex Labview project that was used to create a DLL that matlab may call to order my card PCI-6534 without having to know NIDAQmx calls.

  I am trying to find how to make these calls directly from Matlab NIDAQmx, but I do not get the same results when I call this DLL mentioned above, so I thought I would try to give a sense Labview projects live I begins to make sense of the general economy of the screw, but I would like to be able to run the project , step through it and perhaps see NIDAQmx orders (or something equivalent, so I can determine how to call NIDAQmx commands in Matlab).

  Is this possible to do?

  Thank you

  Jason

  Yes. The toolbar allows you to turn on highlighting so that you can run the VI and see the content of the son. You can put sensors on the wires. You can single-step through the code. This is explained in the help of LabVIEW under Fundamantals-> running and debugging screw-> Concepts-> Debugging Techniques.

  In what the question implied in the title of your message, don't you can directly convert LabVIEW C code in the development environment. Yes, there are tools to convert LabVIEW in C, but which is intended for microprocessors.

• Code sharing with LabVIEW SP1

  I'm working on a project involving the treatment of video information with some students.  We all 2015 LabVIEW installed on our computers and keep the project LabVIEW code in a Subversion repository to which all religiously to validate and update.

  If I install the LabVIEW 2015 SP1 upgrade (from the USB of the spring of 2016), I have 'break' the opportunity to share the code with them?  I noticed that the update of LabVIEW (probably) gives me the opportunity to move from elements isolated to SP1, but I have not (yet) do, and I am sure that they, also, have not improved.

  I know that to install a new version (for example LabVIEW 2016, in August), he would have us all to upgrade 'in parallel', but I don't remember any discussion on the problems of compatibility between a release and Service Pack version.

  Does anyone have knowledge or sufficient experience to say 'go ahead' or 'wait '?  [OR, feel free to chime in with the Authoritative Answer...]

  Bob Schor

  I'm never more than one version of service pack break compatibility with the 'main' version, even if it may take more time to open your code because each switch between the basic versions and service pack will probably force a recompilation.

  If I select "basic" to perform the conversion, I get an error message saying that it is not a file valid .fp or the version of the file is too low.

  On the site he lables the driver as being of labwindows/CVI version 6.0, who worked for before conversions.

  If I select 'Advanced' I notice that although the .h file is present, it is NOT the .sub file.

  My trial version of the CVI has expired, if I uninstall and reinstall I'll be able to generate a .sub file?

  Or is there another way to make the driver work?

• Error Code 37 running labview 6 with windows XP

  I checked most of the posts about this generic error code 37. Here's my dilemma... Labview 6 running on a windows NT system. This computer is on its last breath, and we want to switch to XP... I installed labview 6 on a XP machine and the program works very well... and I actually get my external device data unless I get the ERROR 37... the great thing is I can not launch a Subvi, which creates a linear between because once I get error 37, stops the Subvi. I don't understand how can I read data from my external device, still get the device not found msg. I even tried to install 7 LV and LV 8 still get the same results.

  To close the Communication port, you could create a new white vi, ask a close visa on the block diagram, he points to the port to close and run the vi.

• How to import codes Verilog in LabVIEW FPGA?

  I tried to import the Verilog code by instantiating followed education in http://digital.ni.com/public.nsf/allkb/7269557B205B1E1A86257640000910D3.

  but I can still see some errors when compiling the file VI.

  Test file simple Verilog is as follows:

  ==============================

  module andtwobits (xx, yy and zz);

  input xx, yy;
  output reg zz;

  always start @(xx,yy)
  ZZ<= xx="" &="">
  end
  endmodule

  ==============================

  and after you follow the above link, we have created the instantiation as file

  ==============================================

  Library ieee;
  use ieee.std_logic_1164.all;

  mainVHDL of the entity is
  port)
  xxin: in std_logic_vector;
  yyin: in std_logic_vector;
  zzout: out std_logic_vector
  );
  end mainVHDL;

  architecture mainVHDL1 of mainVHDL is

  COMPONENT andtwobits PORT)
  ZZ: out std_logic_vector;
  XX: in std_logic_vector;
  YY: in std_logic_vector);
  END COMPONENT;

  Start

  ALU: andtwobits port map)
  ZZ-online zzout,
  XX-online xxin,
  YY-online yyin);

  end mainVHDL1;

  ==============================================

  Sometimes, we observe the following error when we put the flag on the output port.

  ERROR: ConstraintSystem:58 - constraint

  TNM_ChinchIrq_IpIrq_ms; > [Puma20Top.ucf (890)]: INST
  "* ChinchLvFpgaIrq * bIpIrq_ms *" does not correspond to design objects.

  does not match design objects.

  and Interestingly, if we remove the indicator from the port of exit, he sucessfully compile on the LabVIEW FPGA.

  Could you take a look at and please help me import Verilog to LabVIEW FPGA?

  I followed the basic steps of the instantiation on the link above, but still it will not work.

  Please find the attachment for all files.

  -andtwobits.v: original file from Verilog

  -andtwobits.ngc: file UCS

  -andtwobits.vhd: VHD file after translating a simulation model

  -mainVHDL.vhd: master of the instantiation

  Since there is no sample file for Verilog (VHDL file, there but not for Verilog), it's a little difficult to do simple execution on LabVIEW FPGA, even for examples.

  Thank you very much for your support, and I'm looking forward to seeing all your help/answer as soon as possible.

  Records,

  The best instructions we have for integration Verilog IP in LabVIEW FPGA can be found here: using the Verilog Modules in a component-level design. My suspicion is that you did not uncheck the option 'add the IO buffers' in the Xilinx ISE-specific Options parameter when running XST (see page 8 of the .pdf)

  2. what equipment you try to deploy to? If it's a cRIO, have you formatted your controller and reinstalled the software for it?

  3. I did a little research and it looks like a potential problem may be with firewall/antivirus. Here is the document that explains that:

• float to bytes conversion using c code in labview

  Mr President, I made the taste of the float to bytes conversion using type cast in labview. now I want that conversion using the code c. means I want to know that how labview can suport code c. farmula node is not suporting my code which is working wel in labwindows. kindly help me on this subject so that my skil can be improved using labview

  The node of the formula as its name suggests is to facilitate the access of the algebraic formulas in text form and uses a C like syntax, but is in no way a fully featured parser/compiler. It supports only a subset of the syntax of C for obvious reasons. Why would you need to implement entire code C in LabVIEW for LabVIEW program supports the same functions and to do it with LabVIEW nodes, you will always have better performance you can get in the formula node.

  If you have real C code you wish to call in LabVIEW you use the node form but create a DLL from it and call it via the node library call.
