Interface Labview with custom board
Hello, I want to use Labview with a board I designed. To be brief my board has an Altera FPGA, some memory, and a fiber-optic transceiver. I want to develop a Labview program to display the data I'm receiving from my fiber-optic transceiver. I want to know if this is possible to have Labview interface with a non-National Instruments board? What do I need in order for Labview to work with my board. In my previous design I had the received data written directly to the computer's main memory. Could I do something like that, just tell Labview where in memory to get the data to be displayed?
thanks,
joe
Absolutely. I'm doing that right now with VISA. Look at the posting here. There are some links there in how to procede.

Interface labview with the test board to identify opamp pins automatically
is it possible to interface LABVIEW to a test board in such a way that the input, output pins of an op amp (8, 10, 14, 16 pin opamps) are identified automatically when DUT is placed in the socket

Thanks alot. pin numbers are variable. I need to test the functional and test parameters for 8, 10, 14, 16 pin opamps.
The first thing you need to do is ensure that +VCC, -VCC, and GND are always connected to the correct pins. I think the best way to do this is have preset wire options that you manually select with some switches (reduces the complexity of the LabVIEW controlled wire switching).
pratheek wrote:
The desired out put for my project is to check the functionality of the opamps
I understand the end goal, but what you need for first specity is the test sequence.
1. Identify In/Out pins & number of op-amps. What is the sequence for this??? What voltages do you apply to the various pins and what is your desired outcome??? How do you identify each pin as in/out and whether they are for OpAmp1, OpAmp2, etc. Since this sequence will inevitabely apply voltage to the output pins, make sure your test sequence doesn't damage the chips.
2. After identfying each op-amp, what is the test sequence for evaluate its "functionality"?? Do you wish to evaluate the gain for various resistor combinations in an external circuit????
3. Now with your test sequences outlined, you can finally begin on getting LabVIEW to implement these functions. I'd use the DAQ digital outputs to a decoder (3-to-8 or 4-to-16). Use the outputs of the decoder to control switches (these switches control the connections between a second DAQ and the test pins). A third DAQ may even be necessary to control the selection of various test resistors. Keep in mind that each of these switches will add resistance to the path so your evaluation must be made measuring the voltages at the op-amp pins (not using the sourced voltage values). Planning the full measurement sequence and requirements before you start will not only help guide your program's development but it will tell you which DAQs are useful and how many you will need.
This is quite an undertaking and we can't really provide any help on the LabVIEW end until you have a full write up of what you want to happen and how (step-by-step details). Once you have that, start thinking about the sequence of events your code will have to follow to make it happen, then come back for guidance/help. -

Are there ways to interface OBIEE with customer application?
Our OBIEE version is 10.3.4 on Redhat, OBIEE connect to a Oracle 11.2.0.2 database running on the same box of Redhat as OBIEE. Our application is java based web application using Tomcat, it point to OLTP database of Oracle 11.2.0.2 on an dedicated Redhat server.
One of the original requirements for the application was to process OLTP data with complecated logic and create reports in text files. Now the customer wants to use OBI to display, print and distribute the reports. The best way to meet this requirement change at the late stage of development appear to be interfacing the application with OBIEE, if possible at all. That way, on clicking a button in the application GUI, a stream of formated data is sent to OBI pressentation service as a response to a request. An OBI client page will then be displayed to shpw the reports, and allow user to print and distribute.
Now are there some OBI APIs allowing an application to call to interface with OBIEE?
Thanks.Hi,
I do not gave further experience with this subject, but I guess this is what you are looking for;
http://download.oracle.com/docs/cd/E12096_01/books/AnyWebServ/AnyWebServ_Overview3.html
You will probably have to do some further research.
Maybe Venkat could be of any help.

Interface LabView with IP camera which supports MPEG4
Hi,I would like to know is there anyway in which LabView can interface with an IP camera that only supports MPEG4?
I need a simple program where LabView is able to capture live video or image from camera and save them as a file which can be send through email.Hello
Even i am unable to interface my android smartphone camera with labview even when i used IP Webcam and droidcam.
Although it has been interfaced as it shows my cam in MAX but it doesnt show the camera in the program i made for video acquisition.
the same program works well for my laptop camera.
I am attaching the screenshots as well.
Hope u help me out with.
Also if possible can you guide me through a link of its tutorial if i am wrong.

Interfacing LabVIEW with Meta Morph Journal
Hi
I'm just starting a project where I must fully automate an experiment involving a microscope and a microfluidics manifold. I am planning to use LabVIEW to control the manifold and Meta Morph Journal to program the motions of the microscope stage and I'm wondering if it's possible to interface the two (i.e. have one talk to the other to coordinate the actions).
ThanksHi Shaheen,
You can get started by followind this tutorial which explains how to add your instrument so that MAX can see it and establish communication with the device.

Interfacing LabVIEW with SIEMENS s7-300 PLC
Hi all,
Im using LabVIEW 8.6 and DSC module I want to interface S7-300 SIEMENS PLC with LabVIEW. I've gone through the turorial on the NI site " Connect LabVIEW to any PLC". By following the tutorial when I am trying to create I/O server in the registred OPC servers window there is nothing what would be the reason. Also there is no specific information available about the hardware connection etc. Kindly help me through this or suggest some tutorial links. What about the PROFIBUS and MPI. I know the information i am giving is not specific and focused but I've tried to tell all of you to atleast understand what I want to do. Hope you people help. THANKS.
NaqqashHi,
Lookout is our legacy OPC software that was phased out by the DSC module. You can read about both here: What is NI Lookout? and What is DSC?
You can find a great introductory DSC tutorial here: Getting Started with the LabVIEW Datalogging and Supervisory Control Module. A couple other places to get started: NI Module Training (look for DSC) and Connect LabVIEW to Any PLC Using OPC Webcast
As for simulating your hardware, if you have a 3rd party simulator that will imitate your hardware, you might be able to fool DSC into thinking that there is actual hardware connected, but DSC does not include simulating capabilities itself.
Cheers,

Interfacing LabVIEW with PS-325 power supply
Hello guys, I have a power supply from Stanford Research systems, PS-325. This power source have a comunication port with pc that requires a KUSB-488B cable. I have installed the drivers necesary for this cable and drivers for power supply from NI site, but doesn't work. I have a dedicated GUI from Keithley with i have tested the cable and conection, and all good but in LabVIEW doesn't work. I have made a simple VI to set the voltage to power source and I'm getting ERR (-10737807343). Can anyone help me with this? maybe somebody have a VI for this power supply. Thank you!
Attachments:
hv_vi.jpg 58 KBIt doesn't require a controller from Keithley. That's a choice that you or someone else made and not exactly a good choice. If Keithley provides its version of VISA, you need to install that but also NI-VISA as primary. The actual gpib driver must come from Keithley. You probably need to enable tulip support as well. The controller and instrument have to be listed in MAX.

Hello, I want to interface LabVIEW with MATLAB using TCP/IP for data transfer. Can anyone, please give me a step-by-step instruction to how to do this? Or else can you point out where I can get them? Thanks.
Solved!
Go to Solution.Hi Sanchu,
As TCP/IP is such a generic protocol then you should be able to fairly easily build TCP/IP interfaces for both your LabVIEW and Matlab code and transfer data using ASCII, or variants etc depending on what sort of data you are trying to transfer. I'm not too familiar with Matlab, but on the LabVIEW end there are some very good TCP/IP server and client examples that ship with LabVIEW.
Another option that you may want to consider, and the reason I'm answering this is that I've recently done a project whereby we took some legacy Matlab code which we wanted to transpose into LabVIEW so that we could then fully automate a test system we have using TestStand. Much of it we were able to derive LabVIEW equivalent functions, but for some functions where LabVIEW didn't appear to have a suitable equivalent, or where it was simply more efficient, we simply copy and pasted the Matlab code into either in the first instance MathScript nodes (not dependant on Matlab) or Matlab script nodes (which will hopefully return to at a future date to fully transpose over to LabVIEW so that we are no longer dependant on a Matlab licence).
In both instances the relative ease of doing this was very impressive, and we were able to wrap huge amounts of Matlab code within LabVIEW with very few issues. As an idea, have you considered wrapping your Matlab functionality in this way and then keeping all the TCP/IP client and server comms within LabVIEW?
N.B. if you haven't found it search the palette for 'Matlab Script'
Best of luck,
David

I have found a person who has a driver software to connect Labview with a general PCI card. But he says that i need to download a freeware software from NI website to configure the PCI card. But you have mentioned that freeware is for GPIB boards. Is it correct ?? Is there any other way out ??
I would ask the person who told you about the freeware software to help you find exactly where it is. I am not aware of any freeware software for configuring motion PCI cards but maybe the person you know might be able to help you locate it.

how to use labview with gpib to connect with Agilent PNA E8362B ?i am newbie ..just started to work on labview about a fortnite bck and +i am a novice in interfacing(networking... jst know tidbits) skill ..so plzzzzz explain me in a litle detail
Sir
We were able to solve that problem...but now could you advice as to which DC power supply we should use (preferably avalable in India) so that it can be controlled by Labview (through a gpib/rs232/any other port) to give a square wave of desired frequency/other parameters.

Interface labview program with real appliances
How do i interface labview program with real life appliances. For example: interface with light bulb
I suppose you could also find some kind of adapter to turn it into an IP based appliance and you could control it through the ethernet. Or you could wait a few decades and interface LabVIEW 2059 with your cranial implant to directly control your light bulb.

Is there a way to interface Labview Web GUI with Fusion Charts?
Is there a way to interface Labview Web GUI with Fusion Charts for dynamic web presentation?
http://www.fusioncharts.com/I have a ballistics program which our clients can use (see attached). Basically there is a series of Cascading Combo boxes that the user must select for Bullet Manufacturer, Caliber, and Bullet ID. The program then goes out to the relevant data file (.CSV) and provides ballistic inputs for the selected projectile. The user is also required to enter in additional data, such as Sight Height, LOS Range, Temp, etc.. Once all data is input, the user either hits the Calculate Button or the Tab (I'm using Event Structures and I now realize this is an issue for Web UI Builder), and the data gets passed to a MathScript which then crunches numbers and spits output to fill a table and a series of Graphs based upon the tablulated data (if so desired).
I was hoping to use Labivew for the first two parts ( Data Collection and Number Crunching) and use something like Fusion Charts for the presentation. I tried learning Ruby on Rails. I was successful with the Ruby part (basically the Mathscript portion) but really got hung up on the Rails section and the need for something like JSON to interface with it. Could not find a useful source of information which really showed you how to combine the two effectively.

Issues in ARM and LV
Can I use my custom board with LPC2378 processor with ULINK2 on Embedded module for ARM and LV.How can I create my elemental I/O vis or I have to use the existing Keil board vis. Confused. Please help.
I have LV8.6. Which ver of embedded module for ARM should I buy. Website shows combined price for ARM module and LV. But I already have LV8.6 so what is the cost of module.
Regards
ShradhaIf the processor of your development board is the cortex-M3 core, I think you do not have to buy keil board. Now, there are a lot of OS and emulator suitable for Cortex-M3.
Operating system I am referring to is the real time operating system such as keil RTX,uCOS,FreeRTOS,CooCox CoOS and so on. CooCox CoOS is very new, you can get more information from http://coocox.org/ .
Emulator or debugging tools such as ULINK2,st-link,Jlink,CooCox Colink and so on. CooCox Colink is also very new. You can download the Colink Plugin from here Colink Plugin .
