Controlling the LEDs

[Guest Rdogg112]

I've been looking for how to control the LEDs on our blade for quite some time now, and, since I didn't find anything, I decided to try myself and succeeded.

Heres the How-to:

1. Install the Android SDK(Or just ADB)

2. Run "adb shell"

3. Run any of these commands:

Activate Backlight-leds(White): echo 255 > /sys/class/leds/button-backlight/brightness

Deactivate(White)		echo   0 > /sys/class/leds/button-backlight/brightness


Activate Red leds:	 echo 255 > /sys/class/leds/red/brightness

Deactivate		 echo	 0 > /sys/class/leds/red/brightness

Blink:			 echo	1 > /sys/class/leds/red/blink

			 echo	 0 > /sys/class/leds/red/blink


Activate Green leds:	 echo 255 > /sys/class/leds/green/brightness

Deactivate		 echo	 0 > /sys/class/leds/green/brightness

Blink:			 echo	 1 > /sys/class/leds/red/blink

			 echo	 0 > /sys/class/leds/red/blink

Just a little tip: If you want to control the green or red led, you have to "deactivate"(Turn off brightness) of the White ones..

If it was an RGB LED...

If its RGB then theoretically it should run this...?

Activate Blue leds: echo 255 > /sys/class/leds/blue/brightness

Deactivate echo 0 > /sys/class/leds/blue/brightness

Blink: echo 1 > /sys/class/leds/blue/blink

echo 0 > /sys/class/leds/blue/blink

It's not an RGB Led, there are only 3 seperate LEDs, White, Green and Red.
