Interfacing FPGA with Frame grabber

Hi,
I'm using an IR camera with a Lattice ECP2M50 FPGA which I need to interface with the 1433 Framegrabber. Is there any way to do this such that I can send some commads via framegrabber to our FPGA to control the camera specifications ??
How to I do this ?
Thanks

Ultimate the serial port on the board is controlled by the code on the FPGA. There are shipping examples that provide the FPGA-side implementation of interfacing the serial port to a host-side interface, which then bridges it to a TCP port, which is bridged to a DLL called "clsernif.dll", which interfaces through the common "clallserial.dll" that Pylon can use to access the camera.
Depending on your needs, you could interface at any of these layers.
-If you need to do this with the ultimate in determinism, you could have the FPGA issue these serial commands directly as needed
-If can do it from the host CPU, you could modify the host-side code and send/receive serial traffic to the FPGA code directly
-You could examine the example code that bridges to a TCP port and simple write some host VIs that talk directly to it by opening a TCP session to the socket it uses.

Control exposure time and gain with FPGA as frame grabber

Hi,
I'm using a Basler acA2000 340kc camera with a PCIe1473R FPGA as frame grabber.
I managed to obtain images succesfully by modifying some of the sample codes. I can also control some of the camera settings thorugh the Pylon software.
Nevertheless, I'd like to control the exposure time and gain in LabView.
Any idea on how to do this?
Thanks

Interfacing with Scion Image Frame Grabber?

I have a Scion Image Frame Grabber in my PC & am trying to control it via LabView Vision. Scion has no LabView drivers, but has a dll & SDK available. However, their driver expects C++ pointers as arguments & returns ptrs. My thought is to write a cover driver in C++ to shield labview.
Anyone have drivers for this, or experience with this frame grabber board?

Thank you for posting on the forums. While National Instrument's driver and native IMAQ support obviously does not interface to third party boards, if your board does include a dll that allows you to control the frame grabber then you may be able to get the board working in LabVIEW. LabVIEW has a few options available for calling dlls, and this is probably the route you will want to go, unless another user already has a driver for this board and LabVIEW available.
To get more information on calling dlls and interfacing to external code (particularly C/C++ code), then I would start by looking at the "Using External Code in LabVIEW" document. You can find this by opening LabVIEW, going to the Help menu, and clicking on "Search the LabVIEW Bookshelf..." This will ope
n a pdf document that links to other great resources, one of which is the large "Using External Code in LabVIEW" document. Glance through this manual and then other information/examples on ni.com/support for some help in getting starting in calling DLLs from within LabVIEW if you have never had experience with this before.

Has anyone been able to use a DataTranslations Frame grabber with CVI? I am trying to use a DT3152 in place of NI1408 frame grabber...

DT does not provide drivers for this hardware to interface to CVI or LabView. Has anyone had success?

you can find a LabVIEW driver at:

Automation Open (CoCreateInstance) with BlackMagic DeckLink frame grabber

I am trying to interface BlackMagic frame grabber hardware that has a COM driver. The C++ demos for the driver work flawlessly, but I fail to access the COM components from LabVIEW. The driver is initiated in C++ with
CoCreateInstance(CLSID_CDeckLinkIterator,NULL,CLSCTX_ALL,IID_IDeckLinkIterator,(void**)&pIterator);
As far as I understand the corresponding LabVIEW command should be to use Automation Open with either CDeckLinkIterator or IDeckLinkIterator as automation refnum. However for both refnums LabVIEW returns an error when executing Automation Open: Error 3005 occurred at Automation Open: Object specified is not creatable.
When I look at the demo code provided with the COM driver, there are really two COM commands that are executed before the CoCreateInstance
AfxWinInit(::GetModuleHandle(NULL), NULL, ::GetCommandLine(), 0)
CoInitialize(NULL)
Does anyone have a clue why the Automation Open might be failing in LabVIEW but CoCreateInstance is not failing in C++. Is there a possible workaround? I have tested this with both 64- and 32-bit LabVIEW 8.6.1.

Hi,
I made some progress...
I found a response to my first question in the forum, with a link to :
http://digital.ni.com/public.nsf/allkb/6EC98441BFAF93A486256DCD000179A2?OpenDocument
so the solution of this problem is in snipet decklink1
My remaining problem is about the configuration of the callback. It doesn't seem to work like in LV examples, or forum examples, as I cannot reference my callback VI as the callback function, and I get no event in the 'register for event' node.

Is the NI 1426 frame grabber compatible with a Line/Linear array scanner?

Is the NI 1426 frame grabber compatible with a Line/Linear array scanner?
I am currently doing a feasibility study of project which uses NI 1426 frame grabber and a Linear Array Scanner, and I would like to know if they are compatible with each other.
Thanks in advance
Sandeeo
Solved!
Go to Solution.

Hi sandeepchinni,
I agree with gunnesjr that we need more information about what you mean by Linear Array Scanner. Like he said if it is a line or area scan camera then yes it will most likely be compatible. A little correction from what he said. You do not need to purchase NI Vision if all you need to do is acquire images. The framegrabber will come with the software that is need to work. If you need to do any kind of image processing then you will need NI Vision. The following knowledgebase lists what is installed with driver for the card. Which Vis are Installed with NI-IMAQ and Vision Acquisition Software?

IMAQ Vision Software with FlashBus MX Frame Grabber?

Is it possible to use IMAQ Vision Software with a FlashBus MX Frame Grabber Card? In the manual I only find references to NI acquisition boards. Unfortunately I have to make do with the hardware I already have.

Heiko,
It may be possible, but you will need to find out if there are any LabVIEW drivers for the card.
Vision analysis can be split into two components. The first half is getting the images into the computer with a frame grabber card. This can be done easily using NI frame grabbers, or with varying degrees of difficulty using other frame grabbers that have LabVIEW drivers.
Once the images are in the computer, IMAQ Vision doesn't care where they came from, so it can be used to manipulate images regardless of the source.

Video acquisition from frame grabber

I wanted to acquire image from a video camera which only has analog output. To do that, I used a framegrabber, called :"Hauppaugel analog video giditizer".
However, as I can see from the list, the framegrabber provides image with YUY 2 format and in the list of my Labview vision module, I could not find such type.
I have written a code for acquiring image which works fine with normal web cameras. however, when I want to use it for acquiring the image from frame grabber, it gives following errors:
1. Error code: 1074396120 Not an image
2. Error code: 1074396015 Cannot connect to camera, it may be in use.
I guess it has something to do with the formats of the picture, but I really don't have experience with that. Could you help me out? The code is attached.
I lookforward to your advice and thank you in advance for the help.

Hello,
First, you have to know that your camera must be Direct Show, otherwise, you won't be able to use it in LabVIEW.
If it is compatible, then you will be able to grab image using IMAQ USB, but keep in mind that this set of VI is no longer supported as IMAQdx is fully compatible with DirectShow cameras, and much better than IMAQ USB.

Converting images from a Matrox frame grabber to LV?

How can I convert an image captured with ActiveMIL Lite from a Matrox frame grabber to an IMAQ Vision image?
I grab the image in LV using the ActiveMIL Lite functions. After that I will analyse the image using IMAQ Vision. So I have to convert the Matrox image to a LabView Image.
Thanks for help

Uli,
I believe Graftek Imaging has LV drivers for Matrox frame grabbers. You can call Robert Eastlund at (800) 441-2118 and he will be able to help you.

Need information on USB frame grabber Labview compatible (planning to buy)

Hello all,
I am looking USB based frame grabbers which are compatible with LabVIEW only. I need atleast 50 frames/sec acquisition rate. I am using PULNIX P2013P analog or monochrome CCIR camera with LabVIEW 8.2 version. Please suggest me any of such frame grabbers even third party products if they are available and also only compatible with LabVIEW.
regards
visu

There are no USB frame grabber cards provided by NI. The only form factors that are supported for frame grabbers are PCI, PCI-e and the PXI platform. If you are interested in using USB cameras, then all you need is NI-IMAQ for USB driver (the driver is not officially supported by NI) and a USB camera that is supported by the driver.

How to remove noise on images acquire from Digital 8 VCR to PCI-1409 frame grabber ?

I have some constant noise in the form of a discontinuous white horizontal line running accross the top of images which were grabbed from a digital 8 video signal. I have tried all the settings in MAX to remove these and have check the integrity of my connections, but to no avail ?

Kyle,
I found that adjusting the acqu window did the trick.
It seems that all the video i have on Digital 8 tapes gives me the same problem. When i use the camera directly to the frame grabber there is no problem.
In due course i'll try another camera with the Dig 8 VCR and compare these output picture quality.
Thanks for the advice,
Fraser

Pcie frame grabber/capture card

Could anyone suggest a compatible (v4l support) frame grabber/capture card.
main concerns are that i dont have to write a driver/api for this card (instead i want to jump right in to writing some capture code), linux compatability and it must be PCIe x1 to x16 should be fine.
Any input connection, though I dont think i can do much with dvb-t/terrestrial..
Thank you!

All input sources are acceptable dvb-t/terrestrial.
Analogue/S-video/composite/vga/DVI/HDMI are all good
PCIe is mandatory, yes.
Cheers ;D
P.S. The frame grabber will be used to test my rtp project

Code example link frame grabber Dll in LV

Hi,
As example to develop my own Frame grabber driver for LabVIEW
Where can I find the sources of a LabVIEW driver for a frame grabber,
linking the grabber's Dll ?
Thanks in advance

Install NI-IMAQ and look into the VIs. But really don't expect to much
here. This is specifically for the NI-IMAQ DLL which has its own
concepts most likely quite different to what your frame grabbers card
DLL does. In addition the NI-IMAQ VI code is not exactly the most well
designed and nicely wired VI code you could possibly find.
In short if you do not know how you would have to access the DLL from C
(not familiar with the API or even more difficult not have some good
C knowledge) it will be a though exercise and most likely never work and
you would be better of payin
g someone in your area who does know.

Synchronisation of frame grabber and DAQ board

I want to aquire images and analog voltage signals at the same time, and synchronised, using a NI PCI-1428 Camera Link frame grabber and a NI PCI-6014 DAQ board. Can this be done using the RTSI trigger functions? I know that the frame grabber supports this, but what about the DAQ board?
How about synchronising a NI-board with a non-NI frame grabber?
Thanks a lot!
Peter

Hi, Peter,
No, the PCI-6014 DAQ board does not support RTSI. However, most of the low-cost E-series NI data acquisition cards do support RTSI, such as the PCI-6024E or PCI-6036E, so you might consider using one of those boards instead.
If you decide to go that route, there is a useful tutorial that describes the signals that can be routed over RTSI for NI DAQ and IMAQ boards:
Developer Zone Tutorial: Synchronizing Motion, Vision, and Data Acquisition
as well as several example programs:
Developer Zone Example: Integra
ting IMAQ and DAQ with Single Display
Developer Zone Example: Low-level Triggered Ring (with DAQ-supplied triggers)
As for a non-NI frame grabber, that would really depend on what support the frame grabber has for timing and synchronization. You could route a trigger signal or scan clock out over the PFI pins on the PCI-6014, but you would need to see if the frame grabber is designed to receive these types of signals.
I hope that helps!

Labview won't believe that my frame grabber board is configured?

Thank you in advance for any help
I am new to labview. I am sorry if this is a silly question, but I have worked on it for hours and haven't been able to find the solution.
I am using a NI-IMAQ PCI-1422 board to aquire images from a Pulnix TM 1020 camera. I can successfully see the camera from both the MAX and IMAQ vision builder. When I go to the DAQ Solution Wizard in Labview it says that "You have no DAQ hardware currently configured," and it sends me back to the Measurement and Automation Explorer 3.0 It looks configured to me and all my attempts to configure it more fully didn't make the system happy so I don't understand what else I need to do.
Also, where are the instrument driver VIs f
or this? Do I already have them hidden somewhere or do I need to go and download them?
Any advice that you could give me would be greatly appreciated.
-Anita
Also, in case you are bored, here is an overview of what I am trying to do. I want to write a labview program which will allow me to specify a delay in seconds and then have labview acquire a an image from the frame grabber board and save it to disk, wait the specified delay period and then acquire and save ...

Anita,
Since you are using an NI-IMAQ PCI-1422 board you will not be able to use the DAQ Solution Wizard. Your board uses the NI-IMAQ driver software instead of the NI-DAQ software. You will want to use the Vision VIs which can be found by right-clicking on the block diagram and selecting Functions->All Functions->NI Measurements->Vision.
You can find some LabVIEW examples by checking your LabVIEW directory and navigating to the Examples->Vision directory. You can also find these examples by using the LabVIEW example finder by navigating to Help->Find Example
I have attached a helpful excerpt from an online knowledge base. The full knowledge base can be found pendocument >here. Please post back if you are still having troubles!
