6503 Change Notification

[rsam]

I Need to program a 6503 DAQ board with port A as a pattern matcher. It has to generate an event when bit 0=1. How do I program it without polling the line i LabVIEW.

The NI-6503 does not support hardware change detection. The only way to do it is by polling the line.

Karsten,

what's the pattern match feature? Can't I use it as a change notification occurence?

Thx Ruud.

Hello,

There is no way that you can setup a program with this card which does pattern matching or change detection without polling the lines. To do so you will need a board which supports the change detection feature.
