Hardware driver programming : Help !!!

Question

Hello
I just bought a special X-ray sensor, which came with its ISA interface card
but without any driver. The documentation indicates which registers and
memory range to read and write, and I have to build the LabView driver
myself. I need to program only some basic tasks (such as impose gain and
exposure time, start an acquisition and get back the data), and I planned to
call some C routines with Code Interface Nodes.
I don't have any experience in hardware programming, and I don't know which
C functions I must use to access the memory and registers to dialog with
this card.
Any information (book reference, example program ...) would be very
helpfull.
Thank you in advance.

Helen,
Check out the KnowledgeBase article on accessing the parallel port from NT
(http://digital.ni.com/public.nsf/3efedde4322fef19862567740067f3cc/c80752c53
094c296862565f3007ac765?OpenDocument). The llb and zip files at the bottom
of this article contain NT compatible In Port and Out Port vis. I'm using
them successfully on my NT.
Hope this helps.
