Access global variable in fpga from rt-target

Hi All,
I have a realtime PC with NI-FPGA 7852R.
Generally I used programmatic front panel communication to access variables from FPGA to rt-system since I need the data for control and not for data logging.
The thing is, I bumped into a tutorial and suggested me to use global variables to save resources of your FPGA. My question is, is it possible to access global variable that belongs to FPGA from rt-system? As far as I tried, this does not seem possible.
Thanks,
Auralius

Could you point us towards this tutorial?

  • How can I access global variables in a loaded Applescript?

    How can I access global variables in a loaded script, in Xcode, ApplescriptObjC? Basically, I have a global variable defined in my parent script using "property", and I need to modify objects connected to those variables inside of a loaded script.
    Example:
    Parent script:
    script AppDelegate
    property myTextField : missing value
    //linked to a text field object
    tell myScript to myAwesomeHandler_()
    end script
    Loaded script:
    on myAwesomeHandler_()
    myTextField's setStringValue_("The new Xcode is so glitchy ugh")
    //changes value of linked text field of parent script
    end myAwesomeHandler_
    The problem is, the variable is undefined in the Loaded script, and I need it to have the same value as the parent script, and I don't want to pass the variable through the Handler. Any ideas?

    I think want you are looking to do will need to be done in two steps. Because myTextField needs to be a property for the ObjectiveC part of the code you cannot turn it into a global.
    However if you make a temporary variable global assign the string to it in the handler then set myTextField off of it.
    global myTextFieldGlobal
    script AppDelegate 
    property myTextField : missing value 
    //linked to a text field object 
    tell myScript to myAwesomeHandler_() 
    myTextField's setStringValue_(myTextFieldGlobal)
    end script 
    on myAwesomeHandler_() 
    set myTextFieldGlobal to "The new Xcode is so glitchy ugh"
    //changes value of linked text field of parent script 
    end myAwesomeHandler_ 
    I know you stated you did not want the handler to return a value but I have to ask why? Global's, imo, are not a good idea and really should be used as a last resort.
    One other possibility is to pass a reference to the property to the handler. Not sure if that works in AS of if that would satisfy our requirement of not passing the variable through the handler
    <edit>
    Another though have you tried to define the property outside the script?  That is
    property myTextField : missing value
    script AppDelegate
    Not sure if that will work.

  • Can i pass parameter or global variable in view from 6i form

    hi master
    sir can i pass parameter or global variable in view from 6i form
    i use view for some diff column calculation within the date then i use
    where date between data1 and date2
    in view but view not create
    please give me idea how i pass external value in view
    thank

    Hi Antony!
    I feel it may not produce the right results if you
    dont include the where clause and using only group by
    in view.You felt? Please clear, logical thoughts put here, not feelings.
    (It may very well have all the Debit, Credit
    for all the Accid where as the user wants only for
    r some date range)Data range is determinated in Form by user, so if view should give final data set then you must back
    on Ranjana first question: How to pass parameter or global variable to view from 6i form?
    And also as Ranjit pointed out, If you have only
    accid, sum(debit), sum(credit) in View, wheres this
    enddate ??Of course, column entdate (or enddate?) must be included in view...
    Cheers!

  • Call function in LabView from a DLL, then access global variable from DLL

    I have created a DLL in LabWindows with a function and a structure.  I want to call the function from within LabView and then access the global structure.  I am able to call the function from the DLL with a "Call Library Function Node" and can access the return value, but I cannot figure out how to access the global structure.  The structure is declared in the DLL header file with __declspec(dllimport) struct parameters.
    Is there any way of accessing this structure without using the Network Variable Library?
    Solved!

    dblok wrote:
    When you say "access to" or "the address of" the global variable, do you mean to pass the variable as an argument to the function call in the DLL?  If so, then I was not really sure how to pass a cluster from LabView by using the "Call Library Function Node".
    Yes, that's exactly right.  I would include a pair of helper functions in the DLL to read and write the global variable.  Alternatively you might write separate helper functions for each field inside the global structure, depending on the number of fields and whether you want to do any validation on the values.
    You can pass a cluster by reference to a function that expects a struct by setting the parameter to Adapt to Type, so long as the cluster does not contain any variable-length elements (strings or arrays).  The cluster needs to match the struct exactly, and sometimes that involves adding extra padding bytes to make the alignment work.  Variable-length elements in LabVIEW need to be converted to clusters containing the same number of elements as the struct definition (for example, if your struct contains char name[12], you would create a cluster of 8 U8 values, and you could use String to Array of Bytes followed by Array to Cluster to convert a LabVIEW string into that format).  If the struct contains pointers it gets more complicated, and it may be easier to write functions in the DLL to access those specific elements individually.
    If you can't get this working or need help, post your code and an explanation of the error or problem you're seeing.
    EDIT: it is also possible to include a single function in the DLL that returns the address of the global variable, which LabVIEW can then use to access and modify the data, but that's more complicated and likely to lead to crashes if you don't get the memory addressing exactly right.

  • Accessing global variables in a BAdI

    How can we access the global variables of a program from a BAdI ?The BAdI does not have that particular variable as a part of it's importing/exporting parameter.The BAdI gets triggered at a particular point in the program.The name of the BAdI is /SAPAPO/SDP_SELECTOR and the transaction is /SAPAPO/SDP94(Demand Planning: APO).
    Thanks,

    Hi,
        Try to export the variable to memory id or use database memory id.
    Like this.
    Export l_vbeln to memory id 'ZTEST'.
    you can give any name instead of ZTEST.
    or u can export to database memory id
    EXPORT tab = lt_vbkd
      TO DATABASE indx(V1)
      FROM ls_indx ID 'ZTEST'.

  • Function module Global variables not cleared from memory?

    Hi,
    This is may be simple & stupid question ( after posting  4242 posts ):)
    " Declaration in TOP
    data : begin of i_y1yatt occurs 0.
            include structure y1yatt.
    data : end of i_y1yatt.
    types: begin of t_yatt71.
           include structure yatt71.
    types: tcode like sy-tcode.
    types: dflag type c.
    types: end of t_yatt71.
    data : i_yatt71 type standard table of t_yatt71
                   with default key  with header line  initial size 0.
    This is code in the function module.
      loop at i_y1yatt.
        move-corresponding o_y1yatt to i_yatt71.
        if i_y1yatt-werks eq 'N501'.
           move space to i_yatt71-werks.
        endif.
        append i_yatt71. 
        " Here this internal contains the previous entry
        clear i_yatt71.
      endloop.
    This function module is called 25 times in a minute.
    My problem is this
    For example : 1st tranmission is called this fm with 50 records,
    and 2nd tranmission is called fm with 10 records.
    My results are showing
    last record in the 1st transmission is still on the memory while calling 2nd transmission.  ( Here in int table I_YATT71 still contains the 1st transmission's last records during the 2nd tranmission call)
    As per my knowledge if each time calls comes in to fm all gloabl variables get cleared. but some how this not happening.
    Anybody come across this scenario.
    PS. I know i need to use clear statement within the loop as first statement.

    You must understand that when calling a FM, you load the entire function group into memory. IF there are global variables, then they are "alive" for the entire duration of the program execution. Meaning if you call the function numerious times, or even if you call another function within the same function group, the functions still have access to that same global variable space, so it must always be cleared manually by the developer at the required points.  You can not rely on the runtime to clear the global variables at the end of the function call.  So you should clear all you globals as the first operation in your function module call, if that is what is required.
    Is this clear?

  • Guidance required: How to access global panel/file handles from within a dll?

    Hi again,
    I have been tasked with trying to separate an application into a modular form, basically I will have a main application which will be a generic GUI which must be associated with a DLL that contains test sequences. Currently these test sequences make calls to the various panel controls to display the test information, this currently works great. The problem that I am having is trying to understand code that is compiled to create a DLL is made aware of, what is essentially, global constants that are defined in my main application. 
    The purpose of this structure is that we will have a generic GUI for multiple products tests, with each DLL representing a different products test sequence, each DLL will be built using the same framework with the generic GUI in mind. 
    I guess essentially what I am looking for is to call RunUserInterface() from main.exe and control the GUI from tests.dll. Is this at all possible, or should I be using a different approach?
    It would be much appreciated if someone could give me some pointers.
    Thanks very much 

    Well, in my opinion for such a software design, DLL modules should not directly modify the main GUI.
    The main.exe should be responsible from its GUI, so that in case of a GUI modification you should not be have to modify all DLLs.
    Also, in this case, there is no problem of accessing global handles, etc.
    Instead, you should send "messages" to the main.exe from the test DLLs and the GUI should know what to do with each message.
    For messaging between such applications I personally use the DDE library. I find it simple to use.
    Your main.exe can setup a DDE server and the test DLLs can attach to it as a client.
    Each DLL can send its "steps" to the GUI and the GUI can display them and command the DLL to run each step upon user's selection. 
    I have seen menchar's posts regarding "shared memory" usage for such purposes.
    There might be other options, too. 
    It is your decision to make.
    Hope this helps,

  • Accessing Var from main Nib/Class - [global variables]

    I'm sure this is a simple solution and the problem is I'm just not thinking right. I just started programming in Objective C but have come a long way in the past 2 weeks. Pretty extensive knowledge in C# and some java.
    Anyways, I've been creating an app and have streams working, CFNetwork working, network services discovery working and a tab bar with a custom View controller linking to one of the tab-bar buttons.
    So when you click on one of the tab bar items it opens a new nib file. That nib loads a table view. When nib loads it hits a method which starts looking for network services and updates the table when it finds some.
    Now the idea is is to have a selector on the cell and when you choose the service it adds same variable info, ip and port, back to a global variable which can be used through the entire app and all extra loaded nib files.
    Out of all this, I don't know how to access global variables....prob should be the simplest thing to do out of all I've done. I have ideas of how it should be done but don't know how to access it.
    Idea would be:
    MainWindowNib has NSString var that is public with a getter setter. But how can I access that MainWindowNib var from a SecondView.nib file/class. There a way to get the parent of the secondView.Nib? I have no clue.
    Any help would be great!
    Thanks!

    I'm still a bit confused how you access that method.
    Main.nib class : UIApplication
    NSString *port
    SetupView.nib : NSViewController
    view
    -TableView added to view
    -Seperate NSObject for TableViewDelegates
    -When item selcted, pass NSString to [main port]
    How do I get a pointer to port. I don't really understand how to do this with objective C.
    In C# I would be something like: [Not exact syntax but u get the idea]
    public Main : Form
    public string port{get;set;}
    Main()
    sView SeconddForm = new SecondForm(this);
    public SecondForm : Form
    SecondView(Main main)
    main.Port = "8080";

  • How to Set multiple Global Variables without using Controls or Indicators

    I have to set many Global Variables (i.e. declare and initialize them) in a subVI in order to pass them to various other subVI's. The only way I know how to do it in LabView is to create a Globals.vi on which you create a control or indicator for EACH Global Variable. That's fine if you have only a few variables. But I have close to a hundred Global Variables (which come from a configuration file for a large program) and clearly it is impractical and cumbersome to create a control for each global variable. In Agilent Vee, there is a simple function called "Set Variable" that sets the data value of a global variable. Then in other module, you simply use the "Get Variable" function to get back the v
    ariable and its value.
    In LabView you can use the "Invoke Node / Set Control Value" and "Get Control Value" properties to achieve the same thing. But as mentioned above, you need to create a control for each global variable and that is a big pain in my case, with many global variables. Furthermore, the global variables are read from a Configuration Text File to this VI. Is there a way to do it without using the control? Thank you in advance for any help.

    Actually you could create the same sort of facility in LV. All you have to do is create a LV2-style global that behaves as follows:
    To write a value to it, you supply a value name and the value. These pieces of data are save internally in seperate arrays.
    To read a value, you supply a value name. The VI looks up this name in the value name array to return an index into the value array. Output the value you find.
    Frankly though, it sounds like what you really need is not hundreds of globals, but a good way to manage configuration data.

  • How can I handle global variables from different DLLs created based on VIs that access those variables

    My goal is to break apart an entirely LabView created application so I can still use parts of it (builded as Shared DLLs upon on some VIs) in my new .Net application. My problem is that some others VIs (that I am not intending using) are changing those global variables (in the natural data flow of the application).  I could , of course, send the values of those global variables as parameters, but I don't know how should I pass those data types (and their size)... There are some clusters there...

    Your
    problem is of course the use of globals. That is almost always a bad
    idea and asking for troubles once your application gets bigger.
    Avoiding race conditions and undesired influences between different
    parts of your application will take up more and more of your
    development time as your project grows.
    You should look into Functional Globals (LV2 style globals) and shift
    registers for data storage and queues for passing information between
    different parts of your applciation. Using these techniques
    consequently, will require you to spend some more time initially but
    will allow you to grow your application without increasing the
    complexity of managing such things exponentially.

  • How can I run two different vi's in same project which are accessing same global variable with out effecting the speed of the execution of both the vi's

    Hi
    I have build an Labview project with FPGA target .  I have configured an FPGA VI and an host Vi to acquire data and logged the data to a file and stored the latest data in a global variable simultanously. I have configured one more VI in the same project  to access the global variable.  I have build a dll to access both the VI as functions in LabWindows/CVI code.  My task in CVI is to update configured GUI with latest data periodically and run the  host VI continously for a long time and log the data to a file. GUI should update for every one second with latest data for this I am using the second VI in which I am accessing the global varibale in which the latest data has been stored in host VI.

  • Accessing a variable from another script

    Is it possible to create a global variable in VB in the Job VBA code and to access it from VB in the scripts contained in that job? I want to dynamically create a value (a random email address) for use in one script where it is used for registration and then use it again in a second script for login.

    I had a similar requirement and used a slightly different approach to solve it.
    I had to produce some random char strings that would be client IDs to create test client records in my web app. I needed to reference these random client IDs in both a create script and a modify script.
    I found that (and I guess this can come down to personal preference) it was easy to create a "utility function" that writes a file with however many random strings you want in csv format. If your target scripts don't have databanks, just play this sub in the VBA editor, and then throw the output file into the databank folder and databank the field of interest. For subsequent runs, just play the sub in the VBA editor for fresh data. Worst case, you have an existing databank, and you just need to paste this file into it in excel as a new column. Not a big deal. Here's an example of a function I have that I changed such that it would create a list of random email addresses to a csv file everytime you run the sub in VBA. Just drop this in your VBA workspace sharedmodule:
    Private Sub CreateMemberEmailFile()
    Dim intA As Integer
    Dim sngA As Single
    Dim strA As String
    'Dim x As Integer
    Dim str As String
    Dim answer As Boolean
    Dim fs As Scripting.FileSystemObject
    Dim myfile As Scripting.TextStream
    Set fs = New Scripting.FileSystemObject 'Create a new file system object
    ' put the file anywhere you want, doesnt matter
    Set myfile = fs.OpenTextFile("c:\memberemailid.csv", ForWriting)
    myfile.WriteLine "MemberEmailID"
    ' ok, this creates 50 random emails...feel free to change 50 to whatever you desire
    For y = 1 To 50
    str = ""
    For x = 0 To 9
    'sngA = Rnd
    'Select Case (CInt(sngA * 200) Mod 3)
    ' Case 0
    ' intA = CInt(sngA * 48) + CInt(sngA * 10)
    ' intA = 48 + (intA Mod 10)
    'Case 1
    ' intA = CInt(sngA * 65) + CInt(sngA * 26)
    ' intA = 65 + (intA Mod 26)
    'Case 2
    ' intA = CInt(sngA * 97) + CInt(sngA * 26)
    ' intA = 97 + (intA Mod 26)
    'End Select
    'make intA a random number from 0-9
    intA = RandNum(0, 9)
    strA = CStr(intA)
    str = str & strA
    Next x
    str = str & "@test.com"
    myfile.WriteLine str 'write the message to identify a different line

  • How do i create and pass a global variable from one vi to several sub-vi's?

    Hi Guys,
    I am trying to create a program that opens several front panels (sub-VI's) in sequence. in each front panel, the user would open a file that the name is obtained from the previous sub-VI. I would like to know how i could pass the filename and refnum of the file thorough from one sub-vi to another. A global variable would do it in VB, but how do we do global vars in LABWIEW. thanks
    Papish

    I put together a sample VI and Sub VI that illustrates how to pass a Refnum and access a data file while in a Sub VI.
    For multiple VIs just repeat the sub VI process.
    You probably don't wanna use a Global Variable if not needed (can add to the mess down the road haha).
    Let me know if it helps you out! Or if I can clarify anything else!
    Chances are if you have seen VI in the forest it hasn't fallen.
