Re: [Request] Battery charge status on status LED

i wrote a plain script * who drive the led ALL colors with color of the pulse function of time digits when charger is plugged
the idea is to keep led white and modify leds currents

* the script ( Pulsar ) is unfinished and work well until battery is fully charged when full white pattern is changed to full green.
an early variant of the script you can find here :
http://talk.maemo.org/showpost.php?p...4&postcount=33
actual script is more finished and obfuscated and i thought also at battery status indicator.
if i find time i will finish this script with an option of time , battery status or both.

Re: [Request] Battery charge status on status LED

I added a method for preventing MCE from interfering with the leds, and it is available in power-kernel. This adds a dominant attribute called dbrightness to the leds such that if this attribute is set to non-negative, writes to regular brightness attributes are ignored, so MCE works as usual, it just has no affect.

Someone could implement the same for the engines, thus allowing for temporarily preventing MCE from controlling the leds.

Re: [Request] Battery charge status on status LED

Since it was requested, I'll post the script I used.
If you are unsure what it is doing or how to use it, please don't, it can screw up your mce.ini file which will definitely screw up your system, causing you to have to flash it, or possibly bricking your N900. It takes more than just copying the script and running it, additional steps are needed. If you can't figure them out, don't use it. Not responsible for any harm to your phone.

This is just a brute force method, very likely the worst way to do it. As noted earlier in the thread, it resets mce occasionally, which will clear any other notifications (missed call, im, email, sms, etc). Unless you are more concerned about the battery level than other notifications, I wouldn't use it.

I tested it for about 12 hours (1-2 bars, charging overnight, 8-7 bars in morning). It seems to work.

Again, probably the worst way to do this and it will cause you to miss other notifications.

Code:

#! /bin/bash



sudo gainroot

#set variables for current bar level and previous bar level

curbar=`lshal | grep battery.charge_level.current | awk '{print $3}'`

prevbar=`cat /home/user/.ledcharge/lastbar`

 

if [ $curbar -eq $prevbar ]; then

#exit without doing anything

echo `date | awk '{print $4}'`

exit

else

echo $curbar

#set pattern to current bar level

if [ $curbar -eq 8 ];then 

cp /home/user/.ledcharge/mce.8.ini /etc/mce/mce.ini

fi

if [ $curbar -eq 7 ];then 

cp /home/user/.ledcharge/mce.7.ini /etc/mce/mce.ini

fi

if [ $curbar -eq 6 ];then 

cp /home/user/.ledcharge/mce.6.ini /etc/mce/mce.ini

fi

if [ $curbar -eq 5 ];then 

cp /home/user/.ledcharge/mce.5.ini /etc/mce/mce.ini

fi

if [ $curbar -eq 4 ];then 

cp /home/user/.ledcharge/mce.4.ini /etc/mce/mce.ini

fi

if [ $curbar -eq 3 ];then 

cp /home/user/.ledcharge/mce.3.ini /etc/mce/mce.ini

fi

if [ $curbar -eq 2 ];then 

cp /home/user/.ledcharge/mce.2.ini /etc/mce/mce.ini

fi

if [ $curbar -eq 1 ];then 

cp /home/user/.ledcharge/mce.1.ini /etc/mce/mce.ini

fi

if [ $curbar -eq 0 ];then 

cp /home/user/.ledcharge/mce.0.ini /etc/mce/mce.ini

fi



#remove and reset lastbar variable

rm /home/user/.ledcharge/lastbar

touch /home/user/.ledcharge/lastbar

echo $curbar >> /home/user/.ledcharge/lastbar



fi



#now restart mci

initctl stop mce

sleep 2

initctl start mce



exit

Re: [Request] Battery charge status on status LED

is it possible to add more profiles to the mce.ini

like over here

Code:

# Priority (0 - highest, 255 - lowest)

# Policy - 0 only play pattern when the display is off

#          1 play pattern even when the display is on

#          2 only play pattern when the display is off, including acting dead

#          3 play pattern even when the display is on, including acting dead

#          4 only play pattern if the display is off, or if in acting dead

#          5 always play pattern, even if vibrator disabled in profiles

# Timeout in seconds before pattern is disabled, 0 for infinite

# Repeat count, 0 for infinite

# AcceleratePeriod time in millisecond

# OnPeriod time in milliseconds

# BreakPeriod time in milliseconds

# OffPeriod time in milliseconds

# Speed from 1 to 255

PatternIncomingCall=1;3;0;0;30;970;0;1000;180

PatternIncomingMessage=4;3;2;1;30;360;0;100;180

PatternPowerKeyPress=5;5;1;1;0;16;0;16;128

PatternTouchscreen=11;3;0;1;23;0;15;50;255

PatternChatAndEmail=10;3;0;1;23;0;15;50;255

if you notice the first number is the priority so this can make the phone notification LED with higher priority over the battery level indicator

then if the profiles are added we can use the script in the post before to force these profiles to be loaded
thus our problems solved

im not sure about all this
its just pure assumptions so far
i just dont have a spare N900 to test with

but i promise to work with this for now hopefully we can make this come true!!
