[ROM][CM10] (CAMERA,AUTOBRIGHTNESS,AGPS) Dark Mod v0.901 2012-12-17

[cyclon1978]

Hello,

i'd like to share my personal daily rom. Its main purpose is to allow you to read in bed without disturbing your girlfriend.
Secondary, the battery consumption will be less while screen is on.
This is reached with allowing the brightness to go down to the (nearly) absolute minimum. I recommend the "CoolReader" Application with Brightness set to "default" so it will use the current system brightness.

To extend battery life the LED's are configured to be as dark as possible.

Not all brightness control widgets uses the system minimum value, so if you not use the system display settings or the toolbar brightness button you'll have to check if your brigthness widget reaches the minimum of "1", test it with "cat /sys/devices/platform/omap/omap_i2c.2/i2c-2/2-0060/backlight/aat2870_i2c_bl/brightness" in a adb shell or in terminal application.

The rom has a configuration menu in settings/advanced; at the moment you can only configure LTO (Long term orbit) data download which should increase gps performance.

Minor changes:

[*] G-Button long press starts Camera

There are some mods to kernel, so you cant use other kernels with it without loosing functionality. It is based on the repository at the time of the build, so it can be different to the nightly from the same day if that nightly is build some hours earlier or later.

Wipe not needed if coming from cm10 nightly. Every other base should wipe everything except sdcard

User applications from gingerbread, ics or jellybean can be restored with titanium, but no settings, accounts, call logs, etc.

Google apps are not included, you have to flash them seperate.

I will only upload builds which generally work (starting after flash, 5 minutes testing).

well nice of you to develop cm10 ,, but i think you are pointing on a minor bug ,, a main bug wich makes everybody NOT to use cm10 is hd games ,, most crash after 3 second of playing and others doesnt work at all ,, so if u want to fix that its a "gpu overlay" issue :laugh:

Thats is right - but i primary fix bugs/make enhancements concerning my personal usage. Thats selfish, i know

Generally brightness minimum is not a bug - lg sets a minimum of "20" wasting battery, cm 10 uses same value. That has one good effect - if you go in bright sunlight and enable your device with a minimum brightness of "20" there is a better chance to see something.

And the mentioned issue... kernel related i think and not easy to fix for me, but i think easy for the pro's.

 

[CalamitySir]

no no no thats not the problem! the problem with CM10 is the sdcard, apollo gallery and some apps dont work for me because sdcard is in /storage/sdcard0.

 

[RomWiz]

Screenshots? :good:

 

[JaredMLG]

Screenshots? :good:

Its actually mainly based off of CM10 Nightly,so just imagine CM10 nightly,but the screen is darker

Is that any way to have a flashable zip to flash over the current rom then there is no need for wipe?

 

[Dustine_VX]

I may know you!
It's like S...z's method to show his "amazing" ROM.
Step by step, show every project... but never done and useless!

 

[cyclon1978]

If you're sure, that's the problem... i will look into it.

Edit:

i looked into it...

All apps should look in /sdcard which is a symlink to /storage/sdcard0

So... if some apps are having problems with symlink - ouch...
If some apps are looking somewhere else ... more symlinks will help.

Do you have a logcat with some exception like file open in /storage/sdcard/* not found?

Apollo and Gallery work for me (Apollo is generally half baked, so "working" is relative...)

More research:

Jellybean roms (different devices) use...

/sdcard/
/storage/sdcard0/
/data/media/
/mnt/sdcard/

Maybe creating all missing directories (as symlinks to /storage/sdcard0) will help.

Anyway, without an example to reproduce i'm stuck...

This project is usable as daily rom. I am not S...z, i am much older

And my only own project here btw. until now i just provided infos to huexx, he included my mod in zeus rom.

Screenshots? :good:

The rom is much too dark to make screenshots

But aside from this it's just cm10 a.t.m., i will add screenshots as soon as i mod the ui. (not planned at the moment)

hey as ur main objective is darkening......

i wn to kno if you cud reduce the led button lights in your rom. have been roaming around the forum and asking to find an easy way to do this. only solution i found was compiling from source.

so as long as u r reducing lights and compiling, might as well

if you want to disable led light:

adb shell
su
echo "0" > /sys/devices/platform/omap/omap_i2c.2/i2c-2/2-001a/led_onoff

But only until screen lock. I use CoolReader, option "Disable Button Backlight" -> works fine while reading with CoolReader.

The button brightness works not, so it has to be modified in the kernel... at the moment i have no time for deeper changes.

Andreas

honestly i have zero experience with kernels and the like.

but these might help i guess

drivers/leds/leds-bd2802.c

#define BD2802_CURRENT_WHITE_PEAK	0x5A /* 18mA */
#define BD2802_CURRENT_WHITE_MAX		0x2D /*9mA*///	0x32 /* 10mA */
#define BD2802_CURRENT_BLUE_MAX		0x32 /* 10mA */
#define BD2802_CURRENT_WHITE_MIN	0x05/*1mA*/
#define BD2802_CURRENT_BLUE_MIN		0x05 /* 1mA */

thanks

I used 0.2 mA for min, 1mA for MAX and 10mA for PEAK.

Testing in progress....

I do not know if min/max is both really used, at the moment my phone looks always the same, except the white peak on button press.

Thanks for the info!

OP updated with download link for new version.

There are several changes in kernel from ricardo, sound library changed for example. Generally it looks good, i recognized no change to better or worse

Have fun!

thanx for trying.....

i really would like to try a rom which a led light turned down.
i wudnt mind even if the lights stayed off
actually i was happy when the korean ics version had a bug in the lights

i get speeds of around 5kb/s and 5hrs to complete
cud u upload it to mediafire

Hmmm... Who want the lights to be...

a) off
b) off but pressed one flashes
c) as dark as possible

Every vote counts

but.. the (coming) button light notification may not work with a), maybe with b) too, so add to your vote if you want to use light notifications
