Re: Using GPIO pins on Digital Sidecar

thank you very much for getting back to us!

we've been using 12v to test it. as it's a car trunk latch we figured it would be the same twelve volts that most of the electrical system is. It may be possible to trigger it with 5v. (we're testing now) In any case, we'll get power to it, somehow.

The specifications from the manufacturer says that the signal line, the one we'd want to run to the dash board, is 5 volts.

I assume these are two separate things.
we're trying to:
A. Trigger the latch
and
B. send a signal to the dashboard

The thing we're having difficulty with is on the LabView end. How do we send a signal to the GPIO pins? How do we receive a signal from the GPIO pins? Are the Digital Sidecar GPIO pins the best way to be doing this?
