using camera for backlight

[swifty]

why not use the camera to make a guess of the surounding light
and give the backlight controller some hint what we need
if it is dark outside, the backlight can goto 30%
if it is bright, backlight goto 100%
i think this can give some battery savings.

will that not lead to consume more battery keeping the camera ON , already the battery life is poor

[swifty]

it has to be only been activated after resume or reboot.
not always on

Btw if im not wrong, E2 have this already... It should available at e2mod.com... But i never try it...

[swifty]

thanks keaglez for that hint
i found:
http://www.e2mod.com/content/view/44/28/
there is something to play with.
is the source for sensor available?
answer to myself:
yes!

[keaglez]

Yeah, i just tried it and its work in my E2! Its a bit wonderful, even im not sure if we can save more battery from it...

And yep, the source is there...

[swifty]

tried it on A780 and no wonder, it doesnt run (no error).
someone with a working toolchain here?

@swifty
Send the source to me and I will try to make it work on E680i/A780. Still in progress learning A1200/E6 native application build for now. Found some strange issue like a widget raised seg. fault when I change the label text, Russian's FBReader A1200 port raised seg. fault when open the configuration dialog, eClock not working at all, etc. I decided to make my own EZXSysInfo (success) and FBReader (not satisfied enough with Russian's port, still in progress) port for learning purpose. I have working crosstool build from mkezx but too big to share

Cool blackhawk... And if you can make a better one, please do for E2 too...
