PCI_1200 EXTTRIG

[Tan]

Hi all,
I'm building an application using NI's
PCI-1200 card and CVI 5.5.

I'm using CVI 5.5 to buil a software to
interface with the card.

I want to use the EXTTRIG pin to externally trigger a software rountine
to read one analog channel. Anybody
knows how to do this ?

Thankz in advance.
MK. TAN

You will find useful informations in the example 'DAQsingleBufExtTrig.prj' that ships with NI-DAQ. You will find it in samples\daq\ai directory.
Since it's a general purpose example you will have to adapt it to your specific application. I don't know if it's suitable for PCI-1200 too, but could be a good starting point.
