How do I perform 16-bit I/O (handshake and non-handshake) using DIO-24

[paulphillips]

I am using Microsoft Visual C++ and want to output a 16-bit word.

Hello;

The best way to get stated is by using the NI-DAQ shipping examples for Visual C++.
If you go to C:\Program Files\National Instruments\NI-DAQ\examples\VisualC\DI; you can find some usefull examples that you can use as start points for your development. The one that you might want to look at is the one named "DIsingleBufHandshke8255.*".

Hope this helps.

I found out from a National Instruments applications engineer that the DIO-24 does not support grouping. Also, in Labview the PortConfig vi does not actually group multiple ports. It simply makes the PortWrite vi perform writes to each port in succession.
