VS: vrf Digital IO using VEE

Question asked by tapio.ronkainen on Apr 20, 2005
Good stuff!

I have used them years without problems (knock knock:). Extremely easy to program with their Vee lib (makes it's own menu to Vee developer UI). Remember to order that too (not free).

Subject: [vrf] Digital IO using VEE




>  Hi all,
>
         Are there any Digital IO cards that software controllable
through VEE out there?  I know National Instruments makes them but I am
trying to stay away from LabView.

        I need to do the following cheap and efficient.
        I know it can be done with VEE and a logic analyzer or pattern
generator, but that is expensive.

         1. Send out a total of 11 bits of parallel data (TTL).
             (This I can do with hardware I currently have, which is a
HP34970A, and a HP34903A 20-Channel General Switch. (Pull-up to 5V or
down to ground.)
         2. 48 bits of serial data at a 1Mb/s rate, every 20mS.


        I know step 1 can be down in Visual Basic or C to program the
parallel port, but I would like to keep it all in VEE since I am also
controlling GPIB Equipment after the commands are sent out. Also the PC
serial port is not fast enough for step 2.

        Again I know NI has plenty of Digital IO cards out there that
will do this, but has anyone tackled something like this in VEE.

         I would appreciate any suggestions.
        Thanks
        Damian.
