Backlight fade like in Siemens phones - Windows Mobile Development and Hacking General

Can someone modify backlight driver?

I'm also interested in this feature but never heard anything on that

Let the light sensor automatically adjust backlight?

Hi,
why not automatically adjust the universal's background light by its light sensor? I suppose this must be possible (ok, only in "notebook mode", not in "PDA mode"). Or is the information given by the sensor binary: "dark" / "bright"?
I would highly appreciate if the device's display would shine bright in the sunshine and dimmed at night. I'm not a windows mobile developer, but I believe this feature should be possible.
Best regards,
tomestos
The backlight makes almost no difference at all when the device is in direct sunlight... It would be really nice to have the backlight dim a little in dark surroundings though. As far as I know the light sensor on the phone is only 'dark', 'light', but even that is fairly useful.
Is the sensor in the registry anywhere and can its values be edited? I find it doesnt come on in low ambient light enviroments when it would be usefull.

I'm interested in it, too! It's would be beautiful, if the sensor switches between light and dark! But I didn't find s.th. in the registry at all!
I had found s.th in the registry like that: HKEY_CURRENT_USER\ControlPanel\Backlight\AutoSensor
Perhaps it will be helpful for the project
The HP Jornada 928 had such a sensor to control the backlighting, and I found it invaluable - especially in an open top sports car.
However, a manager for their UK support centre told me that they got so many complaints about it (or user problems with it) that they removed it from later/Compaq models.

Not true... My old HP hx4700 still had this feature. And indeed, it is indispensible. Very handy when checking your stuff in the open air. Only downside is when you have a shadow cast over your PDA (say: a window stile or something). Then it would brighten and darken, depending on whether or not the shadow obscured the sensor or not.
On second thoughts: I can imagine where the support calls were coming from...
Nobody an idea?
Hi everybody,
I want to bump this topic up, cause there are so many possibilities in a usable light sensor.
For example, i have found an alarm clock, that can go to "snooze mode" if it senses, that lamp in its ambience has been turned on.
And so on, and so on...
So how to read out from the Windows kernel the state of the light sensor??

Hey, aren't there any developers??
Pease, couldn't we solve the problem of accessing to the lightsensor?

Stop the blinking lights?

Anybody know how to stop the bluetooth and network active blinking lights but still have the radios be active? Maybe a registry tweak or something?
Thanks...
I would also be interested in this if anyone knows...

That would be neat.
I was wondering myself whether anything could be done to make the lights slowly fade in and out. That would be such a cool effect -- and less annoying that the blinking flash. Imagine an app that allows the user to set a variable flash/fade rate. Sweet!
(Not sure it's possible with the existing hardware inside the Wizard. I'm not an electrical guy, but wouldn't some sort of relay be required for a fade effect?)

As a former electrical guy, I can tell you the kind of hardware you would need to fade in and out is probably not part of the circuitry. The best you can probably hope for is to stop the cellular (and maybe bluetooth) radio indicators from blinking at you ceaselessly. For my own part, I happen to LIKE the fact that my wizard blinks orange at me when I have missed calls, messages, etc. but I too would love to kill the other blinkers.
I found this, but the referenced registry marker is not present on my machine:

LED notifications - hackers wanted!

One of the chief complaints that I read is the blinking green LED being quite annoying on pocket pcs. Whilst I don't share this feeling I really wish the blinking orange LED would stay constant when I get a message etc so I can easily see when I need to check my phone.
Surely in all this expanse of WM knowledge someone can modify the way the LEDs are handled? Its not even a complete new function - it is just substituting one already possible setting for another!
Personally I would like blinking orange to be constant orange but I know there are many more that want to see their blinking green light become solid/turned off. How hard can it be to hack devices to have this option?
Does it need to be done at a .dll level?
My Artemis seems to use \windows\htc_lib.dll for its LED control.
Does it need to be done at a registry level?
hkcu\Controlpanel\Notifications\{xxxx}\Options
Does it need to be done with a memory resident program that reads the LED status and changes it accordingly?

Does it need to be done some other way?
Someone please help!!
I don't want to sound rude, but it seems you searched for answers anywhere but the forum.
The LED situation has been discussed several times and some solutions have been offered particularly for TyTN and some other devices.
So search the forum (preferably using google instead of the built in search), you may find an existing solution that will work for your device.
And no, the MSDN reference you provided will not work on the LEDs in question, the access to them is tricky at best.

Turn Off the Keypad Light

I'm wondering if there is a way to turn off the keypad light.
The keypad light only makes sense. I know you can dim the display backlight (a registry change) and that helps a bit, but it would be even better to turn off only the Keypad.
My device is a Trinity but I guess a standard registry hack could exist.
I've searched around and haven't found anything. Any help is appreciated
go to pocketmax.net and look for the keylight version.
I have it and use it and love it!

I've just tried it.
I guess it's perfect for Keyboard but not for Keypad.
Thank you anyway.
Please, no one has any solution ?

the keypad can be turned off by selecting minimum backlight display. if you want to have backlight but no keypad ilumination then you have to change some registry... anyway, this is not a hacker forum, so dont ask such things. shame on you for thinking this way
