• Make sure that wire you all the inputs and outputs of your node library function call?

  This document says "make sure that wire you all the inputs and outputs of your node library function call.

  http://digital.NI.com/public.nsf/WebSearch/7253D2F0D91F68058625752F005AB672?OpenDocument&submitted&&...

  But all the terminals on the right side of the call library node considered "outputs" referred to in the foregoing statement?

  This same document continues to show the right way to allocate memory with this illustration and in the illustration, the right "outputs" are left without junctions.

  

  Am I right in assuming that the only terminals that count as outputs, those who use the code of the DLL (modify) as output?  If it is true, then all other terminals output associated with the values entered alone so don't really account as outputs, correct?

  In the parameter call-library configuration screen there is a "Constant" check box and the help that he wrote "indicates whether the parameter is a constant."  What is this box? for me in the setup of the DLL call

  Finally, assuming that a call from the DLL that is supposed to write in these five outputs, is it legitimate to use constants like this to book a space of memory for the output values?

  

  How about if local variables associated with the output terminals are used instead?

  

  Despite the linked document, it is necessary to connect the corresponding entry for simple scalar output parameters (for example a digital). LabVIEW automatically allocate memory for them. If you do not want the entries for all the output wire anyway, there should not be no difference between a constant and a local variable; I would use a constant to avoid useless local variables.

  For settings that are only entries, there is not need to connect the outlet side. It's a bit simplistic since all parameters are entered only and get one result (other than the return value), you pass a memory address and modify the content to this address, but LabVIEW manages this dereferencing pointer for you. If you want to really get into the details, learn more about pointers in C.

  The "Constant" check box acts as the qualifier "const" on a c function parameter. It tells the compiler that the function you are calling will not change this setting. If you call a function prototype includes a const parameter, then you must mark this as a constant parameter when you configure the call library function node. Otherwise, I wouldn't worry on this subject.

• MenuBar navigator - the top-level node are clickable

  I use a browser from the menu bar in the application of mu.  The data for the menu from an XML file.  The menu contains the top-level nodes, but also of subnodes.  All the nodes under work as expected.  I can click on the node and the action runs.  However, none of the top-level nodes have no subnodes do anything when you click it.  I need these nodes also be clickable and enforcement actions, as do the subnodes.  Is there a property in the menu bar control that I put?

  Thank you!

• I had to do a destructive recovery. Try to reinstall the bookmarks but the 8.0 new OS I installed does not ORGANIZE the FAVORITES so I can't import the. JSON file.

  I'm MISSING 'To ORGANIZE the BOOKMARKS' AND 'LIBRARY' IN 8.0, so I am obviously unable to follow the instructions given. I have Windows XP, not that it is important. I have the. JSON file stored in a hard disk external. Every website I've seen so far says to go to favorite bookmarks / organise and import from there, but there is NO organize bookmarks that I found in 8.0 so I have no idea how to do to import this file to install my old favorites.

  In addition, I don't have whatever it is labelled library either. AND I don't have any Add - ons that can be a problem.

  Organize bookmarks was renamed to display all bookmarks in the version of Firefox 4.0.

  Bookmarks > show all bookmarks or {Ctrl + Shift + B}

  BTW, you will need to restore this backup file JSON, import the bookmarks HTML files that have been exported from a web browser.

• read the multiple analog inputs at the same time

  Hi all

  I use USB-6001 and want to develop an application to multiple tasks in C++. I try to read several analog inputs at the same time, but got some errors. To put it simply, I copy one of the sample code to read in analog data in a channel, and then turn it into function. Then I call this function to thread with the names of different poles (for example Dev1/ai0, Dev1/ai1) and I come across this error:

  "The specified source is reserved. The operation can not be specified such complete"code of State-50103

  I have search the forums, this may be because I use the hardware timing in this function, and this material timing cannot be used simultaneously by multiple tasks. I may have to put all the lines, I want to read in a single task (such as Dev1 / ai0:1). This way I can read two lines at the same time. However, when I try this, I encounter another error:

  Status code "buffer is too small to contain the data read" - 200299

  So here is my question, what should I do if I don't want to read the multiple analog inputs at the same time? Is the thing that hard time cannot be used by several true task? If I have to read several lines to a single task, how to set the settings?

  
  

• How not to set default PFI as inputs to the and door to the counter 0?

  Hi, community of NOR.

• Adding control to select the input of the chart data?

  I have a device which sends several channels of data via TCP.  I created a (attached) VI that analyzes this data in integer multiples.  Can I connect a graph (I use graphics mode band) to one of these inputs.  The problem is there is about 50 channels and I don't want 50 cards of band.  I would like to graphs 4-8, with the possibility to choose the input for each use of a control channel.  Any ideas on how to achieve this?  Thank you!

  Use the table to Index.  Connect the table of Boolean to the Board Index. Connect the channel switch to the Index entry. Connect the output to the chart through the Boolean primitive to (0,1).

  For several graphics expand the Index table and connect the selector for each chart to a different Index entry.

• Structures of the event, radio buttons and the property disable node

  Hello

  I have a very simple VI intended to simulate what I'm trying to accomplish in my program... in fact, when the 3rd option button is selected, I want the text box is disabled and grayed out.  Instead, the case of the event seems to perform the action on the * next * the iteration of the loop.  Can someone tell what I am doing wrong?

  Thank you!

  The terminal of the radio control is inside the case of the discipline concerned.

  (.. .or you can read the new value from the data event [NewVal] node instead if you need the Terminal also).

  Currently, it is read immediately and the value placed in the tunnel. When the event is triggered, the expired value is read from the tunnel.

  Once you pass the terminal in case of the event, it reads only after that the value has changed, and you get the current value.

  Also:

  • You also need an event for the button stop, otherwise the VI cannot be stopped easily.
  
  
  • You have the same property node in any of the structure of the case. Put it down after the structure of the case and one is enough.
  
  
  • Things that are different are inside the structure of the case.
  
  
  • You can combine the cases that are the same (not the default)
  
  
  • You can remove the case of timeout.

• Cannot find the HDL Interface node

  I have MyRio and LabView 2014 with all modules installed and updated to date.

  Xilinx 2014 is also installed and I can compile for FPGA.

  However, in the block diagram I find interface HDL node for the import of VHDL code. As see you in the second screenshot.

  How can I solve this problem?

  

  

  There are no node integration IP in 2014 of LabView. Use instead the HDL Interface Node.

  Yes I used the HDL Interface Node and it has worked very well.

• When I use the library function node call in real time, is loaded only once for all or load the DLL whenever it is called?

  When I use the library function node call in real time, is loaded only once for all or load the DLL every time when it is called?

  I have a critical application in real time, in which I use a piece of DLL function developed in C++.  It is ok?  Make sure any senior developer?

  Thank you in advance.

  The user interface thread is the thread that is used to update the user interface. It's slow. And it's supposed to be that way because humans are slow.

  The call library function node can be configured as this thread to use in the configuration for it dialog box. Please visit the LabVIEW documentation on how to do this.

  Comparing only the specific features that overlap of Matlab and Labview, is there an advantage for the latter to be able to run blocks in parallel? What exactly is the purpose of the Matlab script node in Labview?

  MathScript can be deployed on real-time hardware (if that is the question). I don't know about the others.

• I have two sound cards. Can I use the input to the output to another?

  Basiclly the problem I have is that I use one of my as a configuration of 5.1 sound cards speakers (I put the MIC and line as output) and I found another sound card in another PC. The question that I have, that now I'm not a line or a microphone available for the first sound card, is possible to distribute the Line In input of the other card, to the first?

  Hi KiralyAlex,

  Unfortunately, it is not possible to perform this task, because at some point that a single sound card can be defined as a default device.

  However, you can use your favorite search engine & download any third-party software that could serve the purpose.

  Note: Using third-party software, including hardware drivers can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the use of third-party software can be solved. Software using third party is at your own risk.

  Hope the helps of information.

• What is the analog input of the NI PCI-6229 impedance?

  I am trying to determine the effect of a 12 K resistor that is in series with an analog input of an NI PCI-6229 data acquisition card.  Resistance of 12K seems to be part of a RC filter.  I have a 0-10 VDC source this supply circuit.  What is the impedance of the analog input of the NI PCI-6229 data acquisition card?  If it makes any difference, the analog input is connected in differential mode with a 180K resistor to Gnd AI.

  Thank you

  RWB

  Hi, RWB,.

  The input impedance is classified in the specifications 10 GOhm.  So, the effect of your k 12 resistance should be relatively low.  Take care!
