vrf Vee with the 1553

Question asked by VRFuser on Aug 6, 2003
Cagri and Alex-
We have used the 1553 cards from Condor Engineering for years.  We had to write a simple dll to load parameters from vee to the structure needed for the vendor dll call.  We only had to do four out of all the vendor functions to get what we needed to do.

Hi there,
I may have such kind of problems in the near future. Maybe we will use 1553
bus to communicate with some devices. From the e-mails I understand that the
only remedy to this problem is developing an interface program (between
vendor supplied dll's to VEE type dll's). For most of the cases, we apply
this solution. I mean a card or device without VEE drivers, etc.
Unfortunately I am not sure whether this is feasible. Just think of hundreds
of functions in a dll. I remember that four years ago I had utilized this
solution to a DAQ card without the VEE drivers. Another solution to this
problem is not even bothering with VEE and using the environment that the
drivers are supplied (C, Basic). Or a third case is forcing the
manufacturers to supply the drivers we need. Unfortunately today, we see no
cards/devices/etc with VEE drivers in the market. Is it very difficult to
develop these or the manufacturers ignore VEE users?

May anyone suggest better solutions?

Regards

Cagri
