Re: How to trigger the mainboard buzzer?

You'd have to implement your own code to do this, unless your BSP has
support for triggering that device in some other way. It should be obvious
that Windows CE isn't going to have some sort of standard "mainboard buzzer"
device! That *is* obvious, right? You might see if the Notification LED
(yes, I know that the buzzer is not an LED), is somehow used by your board's
BSP for this.

If not, you'll have to write a driver and decide how to make it work (as a
fake audio device or just a custom driver interface that your application
would have to CreateFile() to open, then maybe DeviceIoControl() to send a
custom message to tell the buzzer to buzz).

Hi Luca,

I have the MessageBeep function tested. This function plays notivication
sounds (wav-files: exlamation, critical aso.) over the soundcard output
line
and not over the mainboard buzzer. Do you know, how I can change the
output
channel from this function?

Thanks

Hi all,

do's erveryone know, how I can trigger the mainboard buzzer from
x86-system
under windows ce 5 from a application written with c++ or cf 3.5? The
system
has a internal soundcard but no speakers. The buzzer is allways
present...

Regards from Germany.
