1 The Basics Day 01 Getting Started;. Hello, I am attempting to write a simple LabVIEW application that uses DAQmx for digital input and output I am using a cDAQ chassis with a NI9401 digital I/O module I have two classes in my code that will interact with the I/O device one which performs edge detection on an input pin and one. Im just curious if any of you have successfully wrapped DAQmx into LVOOP classes (on an application specific level, not wrapping all of DAQmx functionality), and what you have found to be most effective One thing that troubles me about DAQmx is the lack of safety between the type of acquisition.

Day 07 All About Signals;. Since the whole point of DAQmx is to have context sensitive functions (on top of a well designed state model) that simply "do the right thing" when they are called, I'm guessing that the DAQmx API designers would agree that calling the DAQmx Read function on a task that is not yet running should repeatedly try to start the task (until a timeout.
