Single pulse gen going down

[LV NI newsgroups]

On the STCgenerateSingleTriggeredPulse.c example that comes with CVI,
the counter pulse is generated going from low to high the back to low. _---_

What do I have to change to go from high to low and the back to
igh? ---__----

Thanks

You would change the Output Polarity. Look at the function GPCTR_Change_Parameter. As it says in the help for that function, if you change the Output Polarity to ND_NEGATIVE, the default state of the output is high, not low.

Hello;

You need to change the output polarity of that specific counter.
Hope this helps.
