Now that you mention RSInc I am actually beginning to think you are
refering to IDL in the end... I am not using any hardware aquisition
myself, but I know of at least one application: the LIDAR group at
NASA Langley do their data aquisition directly in IDL. I guess the key
is to get familiar with the interface between IDL and C or FORTRAN
(CALL_EXTERNAL or LINKIMAGE) and write/adapt the hardware driver in C
or FORTRAN. Once you have your data in an IDL variable, the rest can
be seen even from an IDL demo version.
