Digital input using digital trigger

[deerinhead]

I want to read a digital input on to a trigger in LabVIEW, any ideas on how I would do this?  I am also using a DAQ 6024E and in LabVIEW I am using DAQmx.

Hi,

The E-series cards are limited in their functionality. You can only perform a software trigger on the two digital lines. This way you will read both lines in a while loop and compare one digital line's current state to the previous state. If you are using LabVIEW you can do this with a XOR and shift register in a while loop.
