Hello,

I am writing an application that will run on a Zeus board running Windows CE 5.0. I have a momentary switch plugged into the PTT pin on J9. Using c#.net, how will I be able to detect when that switch is pressed? Also, is there something special that I need to do to route the iO270 audio to the zeus board audio? I can hear windows sounds from my speakers, but i cannot hear the voice audio coming from the iO270.

thanks

"I have a momentary switch plugged into the PTT pin on J9.

It is a matter of reading a GPIO line.
Details are given on page 22 & 23 of the manual:
Zeus Technical Manual - click here

There are also examples for GPIO on the dev kit CD under:
\Examples\Evc\GPIOTest


"Also, is there something special that I need to do

Unfortunately, the audio doesn't go anywhere from the modem.
Basically the Zeus doesn't cater for it.
It is "data only" (via COM port)
