Turn off PDA screen

[Molnar]

I am trying to perform long term DAQ with a iPAQ 5555 Pocket PC, and trying to conserve as much power as possible. I was wondering if there is a way to turn off the display without allowing the system to enter into standby mode.

Thanks � Chris.

Hello �

I am not sure if the iPAQ 5555 Pocket PC allows you to turn off the display without the system entering into standby mode.
You could visit HP�s website and download the iPAQ 5555 user�s manual. This type of information should be documented in it.

Hope this helps!

You can do it with the 5555, just go into media player and select the option. I'm not sure how to do it programatically in labview. There is code on the MS website, but i've been unsucessful at building this into a dll (Which i can then call from labview). I'm trying to get the PDA to suspend, which is similar.

Hi,

I am having a similar problem. I am trying to sample data using Fujitsu Siemens Loox 560N and NI DAQ USB 6008 for as much as possible.

However,  the device succeedes to sample for only half an hour. How did you solve your problem?Is there any way to susspend to DAQ card or USB power between samples?(I need to sample in a rate of about once a minute).

Hope to hear from you,

regards,

Hi Eran,

Judging by your subject title, I can offer you a freeware utility that
I made to very simply Turn OFF the PDA screen. "ScreenOff", can be
found here:

http://www.appliedpda.com/Products_Freeware.html

Configure your PDA power setting to stay ON continuosly, then execute
ScreenOff, to power OFF just the LCD screen only, and conserve a huge
amount of battery energy. Every other program remains running and
your DAQ sampling will not be interrupted.

Hope this helps. 🙂

:) Funny you should ask. On that same web page where you get
ScreenOff, is below it another app.; ScreenOn. 🙂

This was requested for automation purposes as well.

Not quite sure what you mean.... I assume through Labview? If so,
you will need to research the command to shell execute another
executable.

Usage note: ScreenOff /ANDEXIT

With this command line parameter (/ANDEXIT), ScreenOff will turn off
the PDA LCD screen and exit the program. Which means you will need to
rely on ScreenOn to turn the PDA LCD screen back ON. Without it, a
soft reset will turn the screen back on again. 🙂

Using ScreenOff/ScreenOn allows for automation with the PDA to
preserve battery power by other apps., etc.

Hope this helps. 🙂
