Change Detection With DIO-32HS - 6533

[dhbrantley]

I am using 2 DIO-32HS 6533 cards in a system using VB.Net and Measurement
Studio 7.0. The first 6533 card will be used to send commands to a PIC
processor. The second 6533 card will be used to read data back.

I have looked at the DIO samples for VB 6, and feel that either single or
double buffer change detection will do what I want. However, I'm not sure
that our configuarion will allow it.

The second 6533 card will be configured as ports 0 and 1 grouped as input.
Port 2 will be configured as individual line I/O. Port 3 will be
configured as output. The change detection will come on line 4 of port 2.

Can I use the NI DAQ function DIG_Trigger_Config and set parameter
lineMask to look for a change on port 2, line 4 when port
s 0 and 1 are
what is to be read in? The example seems to show that the change detection
must come from the input groups.

I don't see any reason why the DIG_Trigger_Config function should not work for your application. Why not just use the example as is? Let me know how it works out.
