Has anybody written a LabVIEW interface for FreeView?

Hello
I want to record sound in LabVIEW, the problem with
the built-in sound card vi`s is that data can get lost
(they don`t use double buffers)
There is a very good, free, sound card driver called FreeVIEW, which uses a double buffer (http://www.inesinc.com/sound.htm)
and I was wondering if anybody has already used
it together with LabVIEW.
cheers

Unfortunately I was unable to find a driver for this instrument either. This leaves you with one of a couple options. First, I would like you to submit a request for this driver at:
http://zone.ni.com/idnet/other.htm
We develop drivers based on demand and popularity so the more requests we have for it, the greater the possibility that we will develop one.
If you would like to try developing your own instrument driver (or modify the existing one), we have documentation, model instrument drivers, and driver templates to help at :
http://zone.ni.com/idnet/development.htm
We also have a syndicate of third party vendors that specialize in National Instruments' products and services. Some of the vendors specialize in driver development. I would sugges
t contacting one of the Alliance members at:

If you have any further queries, please let me know

Has anyone written any Labview code for a Luxtron 790, a SRS RGA 100 or a Spectrapro 300i?

I'm looking for some code to control these three devices. I know I might have to write the code myself but if there is someone out there who has already gone through the trouble, it would save me a lot of time.

Thanks for that info. Unfortunately, I just looking for someone who wrote something to change the grating. They supply some library functions written in C and they are called using a .Dll, but when i do call them the grating does not change.

Adaptation of LIFA (LabVIEW Interface For Arduino) to other Arduino compatible boards

Hello evryone,
I am trying to use a ''Sakura board", which is an Arduino compatible board, having similar programming as Arduino. This board is manufactured by Renesas; more specifications on it can be found on the following link: http://sakuraboard.net/gr-sakura_en.html
What I would like to know, is if the firmware used for LIFA to interface Arduino with labview, or the ChipKit firmaware, can be used to this kind of Arduino compatible boards.
My aim, is to use the Sakura Board for acquiring signals from various pins(Be it digital or analog), and setting other pins (Digital) parralelly, using labVIEW, as this is done using LIFA, or LabVIEW interface for ChiKit!!
Thanks in advance for your support.

I haven't had any experience with the Sakura board, so can only go on the information on the website.
I've used the Arduino LabVIEW interface previously, and it basically uses serial communications between the PC and the Arduino. This serial interface is provided by the on-board USB-serial converter (an ATMega8u2 running custom firmware).
From what I can tell about the Sakura, it appears as a storage device when plugging into a PC, and doesn't seem to have a USB to serial converter. If this is the case, then the LIFA toolkit won't work. That said, my understanding of the Sakura board may be incorrect (for example I'm unsure what operation modes the slide switch changes between). If you can confirm it has a USB-serial port then LIFA may work. I guess the key thing is that the serial port is required.
You may be able to use a software serial port (http://arduino.cc/en/Reference/SoftwareSerial) on the Sakura to communicate with a PC, though that would require a PC with a serial port, or an external USB-serial converter. This approach would also require you to modify the LIFA arduino code (located in vi.lib\LabVIEW Interface for Arduino\Firmware\LIFA_Base) to reference the software serial port. It's probably a long shot that this will work, as the software serial library has been written for AVR chips, making use of their specific internal timers.

LabVIEW Interface for Arduino Toolkitについて

はじめまして。
LabVIEW2013にNI LabVIEW Interface for Arduino Toolkit を導入したいと考えております。
NIホームページからNI無料アドオンに進み、Arduino用NI LabVIEWインタフェースツールキットの画面からダウンロードを試みたのですが、
Step　One：　VI Packege Manager　のインストール後、このソフトを立ち上げたところLabVIEW Tools Network及びVI Packege Network に接続できないと表示されます。
どなたか、この現象の改善方法について御教授頂けないでしょうか?
宜しくお願い致します

返信ありがとうございます。以下に実際に表示された画面を貼りますので宜しくお願いいたします。
まず、VI Packege Manager を起動すると、左の画面が表示されます。
エラーが発生しているようですが、ひとまずOKを押すと次の画像が表示されます。
この画面ではライブラリにパッケージが存在していないと表示されており、
表記通りにToolsからCheck the VI Packege Network for Available Packages を開きました。
開いた結果、表示されたのが次の画像です。
この画面では、どうも問題がないような内容が表記されているように思えますが、
OKを押すと、また最初の画面に戻ってしまいます。
　LabVIEW　Tools Network　を起動したところ、左のような画面が表示され、
ネットワークに接続されていないことが分かります。
よって接続を試みるためにHelpからActivationを選択し、ひとまず30 day Trialに登録しようとしたところ、下の画面が表示されました。
　この画面ではサーバーに繋がらないという内容であったので、表記通り黒の太文字の部分をネットで調べたところ、どうもVIPM Professionaｌ　を購入しなくてはいけないようです。
私の考えでは、LabVIEW　Tools Network　に接続あるいはアクティブ化がされていないのが原因だと考えておりますが、その改善方法が分かりません。
そもそもVI Packege Managerは無料でも使用可能であり、LabVIEW Interface for Arduino Toolkitもまた無料アドオンだと認識しており、無料の範囲で導入しようと考えております。（LabVIEW　2013は購入しております）
宜しくお願い致します。

Has anybody integrated with CO-Sign for SSO / Authentication

Hi Folks,
Has anybody looked at Co-Sign for SSO in terms of forms / discoverer in the 11g release?
Gary

Marvin,
You make me feel better. I thought I might have been the only one who had ever done this. ;-) It's not too bad to clean up.
I am referencing old notes, and do not currently have access to an OID instance to verify, but try this:
In Entry Management, look under the default Oracle Context, under Services, and Ebusiness. You should see an entry for your EBS instance. (For example, the full DN might be: cn=VIS,cn=EBusiness,cn=Services,cn=OracleContext). Remove this record, and you should be set. You may need to remove other links to this record under your custom context. For example, there may also be a DN cn=VIS,cn=EBusiness,cn=Services,cn=OracleContext,dc=your_org,dc=com.
I was initially concerned that there might be a ton of junk to remove from OID related to the EBS instance registration, but I was not able to find any other likely entries, and was able to proceed with re-registration without issues after removing these two entries.
Hope this helps!
Regards,
John P.

LabVIEW Interface for third party EtherCAT slaves

I have a third party EtherCAT hardware (slave) and software. I am using and industrial PC with Intel PRO network card as the EtherCAT master. This setup works fine, and I can talk to the EtherCAT modules using the thirdparty software.
Now, I would like to develop a LabVIEW interface to talk to the EtherCAT slaves for testing purposes, since most of my test programs are written in LabVIEW.
Is it possible to write EtherCAT software in standard LabVIEW 2013 using an inustrial PC as Master?
If I use the DLL of the third party software, do I need LabVIEW Real Time module for etherCAT communication?
-Thanks

Hi rosh,
I think it will depend on how the DLLs are designed. If you call the DLL at the right rates, you may be able to avoid using LabVIEW Real-Time. If you want to run LabVIEW Real-Time on your PC, you would need to replace the existing OS with LabVIEW Real-Time. Once you do that, you may be able to run your existing DLLs but compatibility is not guaranteed. This KnowledgeBase article describes the process of determining if your DLL is compatible with LabVIEW Real-Time (NI PharLap ETS is what installs when you replace the OS). For our other Real-Time operating systems on different targets, you would need access to the original source code so you could recompile for the new target.

LabView interface for SRS DG645

I need to implement a driver for my SRS DG645 module connected to my computer by an NI GPIB, does a driver already exist in LabView? I need a LabView program interface on my computer seperate of my module to control it. I read that Stanford Research Systems does not assist with LabView programming for their machines, and so I have yet to find a LabView interface created for this module.
Thanks for any help!
Kelsi

Hi zeddy and others.
Sorry for replying on old post but i got just the same question.
I will be using SRS DG645 for my project on LabVIEW 7.0.
Do i need any driver for it?
When i search at NI website, i found some plug and play drivers for DG645.
but there are no driver for labVIEW 7.0..
http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=D62E8D508F9832E6E0440021287E6A...
Plus, the drivers need NI VISA 5.2 version to work.
Does that version with my LabVIEW?
Here is the compatibility table of Ni-VISA and LabVIEW but there is no LabVIEW7.0 in there.
http://digital.ni.com/public.nsf/allkb/CF4279A34F855AB186257B1F00003B82
Can you help me with it.
Thanks in advance.

Does anybody have a LabView driver for an OPOTEK tunable laser?

I am looking for an already complied and working driver for the OPOTEK Vibrant tunable laser.

Yes, thank you, i looked into that. I seem to be having
difficulty contacting them by phone and email however. I figured
i would try NI and see if anybody has already made a compiled VI.

Does NI offer a generic LabVIEW interface for the PCI-1424 frame grabber?

I am attempting to grab frames from a DuncanTech camera using a PCI-1424. The vendor's software was developed in the LabVIEW, but I only have the executable and they seem unwilling to provide the source file(s) - essentially, the vendor software only displays the images (no capture capabilities). In the interests of time, I would like to locate/purchase a generic LabVIEW image acquisition front-end, if available.

MJP;
Your PCI-1424 card should include several examples. Check the directory where the software for the camera was installed (Usually "Program Files\National Instruments\NI-IMAQ")
Also, if you have MAX (Measurement & Automation Explorer), you can access your card from there and snap images.
Other than that, I think you have to write your own code or ask somebody to do it for you.

Has anybody done a database version for flexstore

I was wondering if somebody has done DB version of
specifically this version of flexstore in flex 2.0
http://examples.adobe.com/flex2/inproduct/sdk/flexstore/flexstore.html
Specifically the UI gets really crawls if you have even 600
items because it loads the entire XML, and the view loads
everything without some form of paging. Obviously this can be
resolved through some of paging such as reading first 10 etc or
querying and getting appropriate data from DB based on filters etc.
So in that context, I would greatly appreciate if you
somebody can share what they have done.

OK, friends, the project is up and SourceView is enabled.
Just keep in mind that I did this purely for study purposes,
so see the original readme for Flextore and the comments in the
original sample project code files. There are things in there that
are not necessarily best practices.
In the unlikely event that you want a copy of the database
file, just let me know by email directly and I will be glad to send
it to you; I cannot give you access to that in my shared web
server.
Happy Fourth,

Has anybody written a Java program to get Source code from a URL ?

Hi,
I have a program written in another language (Not Java) to basically
pull in the source HTM or HTML code, given a URL.
ex. getsource www.any.com output
So, ==> output will contain the source HTM or HTML code of
www.any.com.
Is there a Java program that do the same ? Like to see it.
Please append here, or provide pointer to get it.
Thanks,.... -- gte99te

Here's a quick program that does just that.
I'd suggest taking a look at the Java Tutorial, at it's section on using URLs descibes how to do this, and it shouldn't tank more than 45 minutes to get through.
import java.io.*;
import java.net.*;
public class SavePage{
    public static void main(String[] args) throws Exception
     // make sure we've been given a URL
     if (args.length != 2)
         System.err.println("Usage: java SavePic <URL> <filename>");
         System.exit(1);
     // convert the string argument to a URL
     URL url = new URL(args[0]);
     // open a connection to the resource with the given URL
     URLConnection connection = url.openConnection();
     // get an input stream from the connection, and wrap it in a buffer
     BufferedInputStream bis = new BufferedInputStream(connection.getInputStream());
     // open an output file and get an output stream to it
     FileOutputStream file = new FileOutputStream(new File(args[1]));
     // wrap[ the file's output stream in a buffer
     BufferedOutputStream bos = new BufferedOutputStream(file);
     // read each byte from tne connection, and write it to the file     int b;
     while( (b = bis.read()) != -1 )
         bos.write(b);
     // clean up
     bis.close();
     bos.close();
}

Has anybody compiled OpenSSL for 64 bit PPC?

We want to use OpenSSL as a 64 bit application under Mac OS X 10.4.7 over PPC G5 hardware.
Has anybody had experience compiling OpenSSL for this architecture?
Any special clues for building a working 64 bit library for PPC?
Why doesn't Apple support this? I would imagine performance would be better on crypto operations.
Mac OS X (10.4.7)

Yep, it's a do it yourself thing.

Has anyone created a device driver for the DG101 Programmable Delay Generator?

I am wondering if anyone has written a LabVIEW driver for the DG101 Programmable Delay Generator third party device?

I have looked at the instrument driver network and there is nothing listed there. The board comes with the source code for the device as well as a gui to run under windows but I am working on the PXI-8196 embedded controller running a RTOS so the .dll that comes with the board is not compatible. I have been on the phone and email with NI over the last 3-4 weeks trying to figure out how to import the .dll, how to wrap the .dll, and how to create a new .dll. I spoke with someone yesterday and they told me that I would have to write a register level interface driver to work with the board and that it is very difficult for even the most experienced person. They suggested I outsource it but I was just curious, seeing that this board belongs to a very small community of programmable delay generators, that someone may have written a driver that is available.
Thanks,
Tracy L.

LabVIEW Drivers for Norma 5155 power analyzer

I have several questions concerning a GPIB LabVIEW driver for the power analyzer NORMA 5155 (NORMA is now part of LEM company):
1- Has anybody programmed a driver specially for this device so far ?
2- Is it possible to use other similar drivers (LEM/NORMA 4000..6000) for it?
3- How would you approach building a suitable driver? (Instrument I-O Assistent ...,)?
Any answer could be helpful.
Andreas, Germany

1) There are no drivers for the 5155 at http://zone.ni.com/idnet97.nsf/browse/
(but perhaps someone beside NI has programmed a driver)
2) The same type of instrument from the same company will likely have a similar command set. The drivers for the 4000 and 6000 are Plug and play driver and not IVI drivers, so modifying them would be easy.
3) I would first call LEM tech support and ask what the difference between the commands sets of the the 5155 and 4000/6000 are. If LEM tech support is unable to give a good answer, then I'd try to get the manuals for the 5155, 4000, and 6000 to just compare the command sets myself. If they are very similar I'd just modify the old driver. If they are very different, I'd just make I/O assistant VI for each function in th
e manual, and I would have a low-level driver. Once you have this low level driver you can just combine functions to make higher level VIs.
Hope this helps!
