TLS1.2 implementation using Labview

Dear all.
Recently, I has been developing a server in Labview for receiving the GPRS packet data from a GPRS modem.
The packet data is SSL/TLS1.2 encypted.
Since the Labview has no native support for SSL/TLS, is there anyway to implement the SSL/TLS 1.2 decryption at my server using Labview?
Or plugging the SSL/TLS 1.2 implemention from other programming language into my Labview codes?
Kindly need expert to advise.
Thanks.

Any advise?

I2C implementation using Labview.

Hello ,
I am trying to communicate to my IC using Labview. The board on which the IC is uses I2C interface. currently it is connected to the PC using a parallel port dongle and there is GUI which does this, I want to make a I2C interface so that I can communicate to the IC directly using Labview. Is it possible that I use the parallel port to pass the signal directly to the IC, If yes how do i do that? Or is there any other way I can go about this issue.
Any help is appreciated.
Thanks

The kind of "bit-banging" you need is defined in the Philips I2C spec. You can get a basic overview of the actual protocol from Wikipedia, or you can get the full spec from the Philips NXP site (at the very bottom there's a link to the PDF). Since the GUI developed in-house you should be able to see the code to see what it does. It should basically just be toggling two of the parallel port lines based on the I2C protocol.
Usually when you buy an I2C interface you get drivers for it that you can use from LabVIEW. Some companies provide LabVIEW drivers directly. Examples: Cal-Bay Systems (pretty popular as it's parallel port), Total Phase, Telos, MCC (Micro Computer Control Corporation) and NI. I've used the Cal-Bay interface and the Total Phase Aardvark so I know they work. The Cal-Bay approach is to basically do bit-banging of the parallel port so it's dependent on software timing. There's an open source interface that was designed for Linux, though there's a port of the library to Windows. Have no idea whether it will work with LabVIEW. As for other sources, you can take a look at the code that was posted in reply #4 of this post. The device being talked to is a SPI device, but the premise is similar. It's using the parallel port to toggle lines to generate the protocol. This 2-year old post refers to an interface with LabVIEW drivers that user KC created. Don't know if it's still available.

How to implement wafer mapping using LabVIEW?

Hello LabVIEW Masters!
I am having an incoming project which includes controlling and gathering information from a PROBER. One of the difficulties I am having now is how to implement a WAFER MAP using LabVIEW. According to my customer requirements, the wafer element ranges from 6k to 23k. I guess doing all the element (one die = one led ctl/indicator) will be a hell of a task, especially on how to effectively manipulate each elements. Does anyone have better idea on how to this?
Please, I badly need your help..
Thanks and Regards,
Dennis DG

Hi Dennis,
Is it okay if you send to me the working VI also?
No, it's not ok. I made that program for my customer...
As I am not too familiar in using intensity graph.
That's no reason to hand over programs for free...
My customer also request me that if the cursor hover on the wafer map, he wants the x,y corrdinates to be displayed.
I also have such a feature. Did you notice the little yellow cursor near the center of the wafer? One could easily change that to use a MouseMove event instead...
He also wants to select some elements in the wafer map and come up with the coordinate values to do some testing.
That's related to the cursor thing...
Some points:
- You have a customer that pays you. Why should I offer work for free?
- You can send me contact dates of your customer, I will make him an offer...
- When you take an job to provide software you should be able to code the software...
- The VI(s) are now some years old. I didn't code so well back those days and don't want to hand out those VIs as they are right now.
- I included some "license management" deep inside that program, I would have to remove this and spend time on testing afterwards...
- The VIs are based on the PROBER output format used by the customer. All the file handling has to be changed for/by you...

How to implement a callback function using LabView's Call Library Function Node?

I am trying to call a fuction from a SDK.dll library using the Call Library Function Node. The SDK was provided to
me and I do not have the source code, just the .dll and .h files.
The SdkSetPropertyEventHandler function has a callback fuction as one of its parameters. How do I implement the
callback using the CLF node? I am a good LabView programmer but this is my first time using the Call Library
Function Node. I have read all the info I can find on NI's web site and the discussion board but cannot figure
this one out. I am using LabView 8.6.
The SDK.h deacribes the function as:
// Function:   SdkSetPropertyEventHandler
SdkError SDKAPI SdkSetPropertyEventHandler(
            SdkCameraRef                    inCameraRef,
            SdkPropertyEvent                inEvnet,
            SdkPropertyEventHandler         inPropertyEventHandler,
            SdkVoid*                        inContext );
// Description:
//       Registers a callback function for receiving status
//          change notification events for property states on a camera.
// Parameters:
//       In:    inCameraRef - Designate the camera object.
//              inEvent - Designate one or all events to be supplemented.
//              inPropertyEventHandler - Designate the pointer to the callback
//                      function for receiving property-related camera events.
//              inContext - Designate application information to be passed by
//                      means of the callback function. Any data needed for
//                      your application can be passed.
//      Out:    None
// Returns:    Any of the sdk errors.
A separate header file called SDKTypes.h contains the following data:
typedef SdkUInt32 SdkPropertyEvent;
typedef SdkUInt32 SdkPropertyID;
typedef void       SdkVoid;
typedef struct __SdkObject*    SdkBaseRef;
typedef SdkBaseRef    SdkCameraRef;
SdkPropertyEventHandler
typedef SdkError ( SDKCALLBACK *SdkPropertyEventHandler )(
                    SdkPropertyEvent        inEvent,
                    SdkPropertyID           inPropertyID,
                    SdkUInt32               inParam,
                    SdkVoid *               inContext );

Basically you do not do that. LabVIEW does not know pointers and certainly not function pointers. What you should do instead is writing a C DLL that implements the callback and also exports a function to be called by LabVIEW that translates between the callback and a LabVIEW user event. Look for PostLVUserEvent() here on the NI site to find examples how to do that.

Implementing Differential Equations using Labview fpga modules on PXI-7811R

Dear,
I am working on implementing dynamic systems modeled ordinary differential equations on PXI-7811R FPGA using labview FPGA. Is there any body who can help me how to implement differential equation on PXI devices uding Labview FPGA, please? Is there any integrator in Labview FPGA, module. I used Discrete Integerator in LAbview FPGA module in Maths palette, but i hesistated if it really works . I really appreciate your help,
Gammee

Thank you for posting on the discussion forum.
You can solve differential equations using LabVIEW FPGA but you may run into some significant difficulties in doing so. If you are not tied to using FPGA, you could try using LabVIEW real-time, which may make things much easier. But if you would like to stick with FPGA, see the link below for a list of examples that may be helpful:
http://search.ni.com/nisearch/app/main/p/bot/no/ap/tech/lang/en/pg/1/sn/ssnav:ipn/q/differential%20e...
Below is a link that you can review to better understand the functionality of the discrete integrator should you choose to go that route:

I hope that helps.

How to use labview to control a robotic arm by EMG signal

Hello,
I am working on simulation of an active Exoskeleton (wearable robot) for the upper limb using LabVIEW for my senior project. I need to use the EMG signal as an input to move the elbow joint (flexing and extending). I downloaded labview biomedical toolkit to take a ready simulated EMG signal but have a weak experience in LabVIEW.
The design criterial I am planning to use is to establish a threshold for the EMG signal using a comparator (above 0 for example) and set a counter for everytime the signal passes the threshold as(+1) in every count. Then, specify a degree value for the counter (for example when the counter reaches 10000) and feed this value of the counter to a simple simulated structure for the joint (simple angle of 2 lines) or a meter to represent the movement.. e.g. every 10000 count = 1 degree of movement. Zero crossing can also be used instead of the comparator and the signal will be filtered and that is easy to do. However, my problem is in converting this logic into LabVIEW. I don’t know how to set a counter for the signal and make every number of counts refer to a specific degree of movement and I also don’t know how to form the simulated joint structure in LabVIEW or even how to transfer this into a simple meter device in LabVIEW.
I have only one month to do this project so any help or ideas you provide are highly appreciated
Thank you ,

CarlFHellwig
Thank you for providing this example I just implement it in the software to check the counter results.
In fact, the design criteria I desided to use latly is to use is to establish a threshold for the EMG signal using a comparator and correlate the EMG signal with the angles of movement of a simple simulated structure "motor" for a single joint (simple angle of 2 lines) eg. 30,60,90,120,150 degrees for flexing and extending. Zero crossing can also be used instead of the comparator and the signal will be filtered and that is easy to do.
In other words, the idea is to drive a motor for different angles based on the input EMG signals. I am now stuck with developing the algorithm of how the angles are related to the RMS value of the signal while flexing and extending and how to convert this RMS into angular velocity and angular position to form the simulation.
I will be grateful if someone guided me to a person did a similar project to discuss some issues.

Desperate Help needed in using LabVIEW

Hi,
I'm a beginner in using LabView programming. Can anybody help with implementing Labview 6 and Keithley 2400 SourceMeter for data aquisition? I've wired up the hardware and have problem coming up with the software.. Any idea how to get started?

Hello giam,
I made wrapper vi's for the standard GPIB Read/Write functions to
handle errors (using green icons to distinguish them better). The "send
mult" handles simple strings (like standard GPIB Write) and array of
strings (you often need to send more than one string to a device). But
generally those icons have the same main functionality like standard
GPIB...
To send an array of strings you put the GPIB Write into a for loop and
connect the array as input with autoindexing enabled (as standard).
Maybe a small delay will help for some devices, the K2400 should do
without.
Edited: The greenish delay icon is just a standard "Wait ms" with
additional error cluster in/out to allow dataflow programming...

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.

Since this is a school project I recommend you do the work yourself. You will not learn asking others to do it for you. In addition, folks here will not do your homework for you. We are however more than wiling to answer specific questions for you. Post what you have done or tried and ask specific questions. I am confident you will get assistance.
And to answer your question, yes LabVIEW can be used to implement a scheduling program.

Can you edit file properties using Labview?

Except for the file attributes like 'read-only' and 'hidden', Windows 2000 & XP also have file properties like 'keywords', 'comments' and 'description'.
Is there any way that I can edit these properties in Labview?

RichElswick wrote:
nope, we never got that far and I am no longer on that project.
And it would be a bitch to implement. Basically those properties are implement using propertysheet handlers. That are shell extensions that can be installed in Windows and in the registry added to one or more file types. On loading the property dialog the shell (basically only an Explorer thing) sees that for that specific file type there are property sheet handlers registered and then loads them as an extra property sheet into the dialog.
There is no common API to retrieve and lets forget about changing the information those property sheet handlers deal with programmatically. And every property sheet handler retrieves the actual properties according to his own private information, such as image properties in JPG files but possible also extra information in the meta data of a file on advanced files systems such as NTFS (the security property sheet for instance).
So you would have to create a Windows dialog, load the according property sheet handlers into it and then have the user deal with that interactively. I doubt that this is what you want.

I need to update specific records(of variable lengths) in a file. I can get the correct record but when I update it(add info), it overwrites part of the record following it. I am using labview 6.0

I need to update specific records(of variable lengths) in a file. I can get the correct record but when I update it(add or change info), it overwrites part of the record following it. I am using labview 6.0. I need to be able to insert information into the middle of a file without disturbing the data before and after

It's hard to give more specifics without more detail, but in general you're going to need to read in the entire file, split it into three pieces (everything before the record of interest, the record itself, and everything after the record of interest), modify the record, reassemble the three pieces in proper order, and write the whole thing back to the file.Of course if the file is very large you might not want to actually implement it this way, but conceptually at least, this is what you are looking at.If this file some sort of proprietary format?Mike...PS: this type of issue is why I really like databases...

DC to DC converter basics using Labview on FPGA Control with VHDL

DC to DC converter basics using Labview
I am fairly a novice, that is why simplifications required, before I begin thanks in advancefor them who will response
I am designing a DC to DC (Intermediate Bus Converter, a step down BUCK converter, of 24 v input and output 9 v and 5 amp current output), using FPGA controller, I need to program this using VHDL, for which I take LabVIEW, but as I am new so do not have any idea as what are the steps that I need to take for implementation, what types of function that FPGA does in this so that it can generate 24 v and what other mechanisms that have to control inside or outside of FPGA programming and designing that it can give the desired output voltage, if you have any idea about this then I would be glad to receive the steps that are necessary to complete this

NI supports two Spartan 3E products through either LabVIEW FPGA or MultiSIM, the Digital Electronics FPGA Board (http://sine.ni.com/nips/cds/view/p/lang/en/nid/207010) and, if you are in academia, the Xilinx Spartan 3E XUP starter board (as linked by Dennis_Knutson).
Also note that if you wanted to implement some logic in VHDL and have access to that logic in a LVFPGA diagram, you could utilize the Component-level IP (CLIP) fuctionality (http://zone.ni.com/reference/en-XX/help/371599G-01/lvfpgaconcepts/using_component_ip/)

How to create fourier transform properties using labview

Hi everyone
i am a new user to Labview and i only have 2 weeks left to complete an assignment.
This assignment involves the implementation of the various types of fourier transform properties using Labview. These properties include linearity, time shifting, frequency shifting, time scaling,
I do not really know how to implement them using Labview
PLS HELP!!!
Thanks

i am refering to the fourier transform properties listed below:
A) time shifting
x(t-a) ------- > exp (-jwa) X(w)
For the time shifting property above, i have problem creating the exponential term using labview
B) time scaling
x(at)-----------> 1/a X (w/a)
C) Time convolution
Y(w) = F[h(t) * x(t)] = H(w)X(w)
where * stands for the convolution operation and F stands for fourier transform
Please provide diagrams if possible. Thank you
PLEASE HELP!!!!!!!! THANKS!!!!!!!

How to use Labview 6 to call OpenPrinter()

I would like to use Labview 6.0.2 to call API winspool.drv function OpenPrinter().

[email protected] wrote:
Thanks for your help, but I had already tried the steps you suggested. The OpenPrinter() function takes two input parameters: one is the printer name, the other parameter the printer defaults with its type of data as structure in C, which is equivelent to the data type of cluster in Labview. The only output parameter from this function shall return a handle of the printer, but when I used the labview node to call this function, the output variable returns zero, which means the function call is not working. I suspected the cause is probably due to that I did not correctly pass the second input parameter to the function. I will really appreciate if you could take time to try to run your code to see if you could get it to work.
This is not trivial.
The function prototype is
BOOL WINAPI OpenPrinterA(LPSTR lpPrinterName,HANDLE *phPrinter, LPPRINTER_DEFAULTSA pDefault);
The second parameter would be no problem you just treat it as a pointer to an uInt32 but the third is a pain. Its structure definition is:
typedef struct _PRINTER_DEFAULTSA {
LPSTR pDatatype;
LPDEVMODEA pDevMode;
ACCESS_MASK DesiredAccess;
} PRINTER_DEFAULTSA, *LPPRINTER_DEFAULTSA;
with all but the ACCESS_MASK parameter being a pointer to some memory. You could pass in a NULL for this parameter in which case certain defaults will be assumed and you could theoretically change them later on by calling SetJob().
But here comes the crux of this: Using the returned printer handle for anything (with or without having specified a valid defaults structure) will require you to call many more Windows API functions, and some of them are even more complex than this one. All in all if you really need to do something by opening the Printer Driver in winspool.drv, it is a much better idea to implement that in an external DLL written in C with a LabVIEW friendly calling interface and import that into your LabVIEW application instead.
