Communication between a non-ni board and labview

[Damien]

We have labview 6 and a framgrabber PC-DIG from coreco (connect to a
camera). CorecoImaging/Alliancevision gave us a driver with two file
on it (library).My Frame grabber is on PCI 0 and I just want to
communicate from labview to the board without the IMAQ Vision library.
Can U help?
Thanx

What form are the drivers from the manufacturer in? DLLs? C code?

Damien,
The key is to get a 2d array of pixel data from the PC-DIG board. Hopefully there is some startup documentation which acompanies those libraries.

Once you have the array of pixels use the Vision "array to image" VI, and you will be set to go with the IMAQ Vision library.

Hope this helps,

Copying an array of pixel data into an area pointed to by IMAQ
GetImagePixelPtr works too. If you want to explore this alternative,
that is savely using the memory manager of IMAQ, use respectively IMAQ
Create, Set Image Size, GetImagePixelPtr followed by your own DLL call
to copy pixel data, WindDraw, UnMapPixelPtr, Dispose and WindClose.
