What: /sys/class/leds//brightness Date: March 2006 KernelVersion: 2.6.17 Contact: Richard Purdie rpurdie@rpsys.net Description: Set the brightness of the LED. Most LEDs don't have hardware brightness support so will just be turned on for non-zero brightness settings. The value is between 0 and /sys/class/leds//max_brightness.

What: /sys/class/leds//max_brightness Date: March 2006 KernelVersion: 2.6.17 Contact: Richard Purdie rpurdie@rpsys.net Description: Maximum brightness level for this led, default is 255 (LED_FULL).

What: /sys/class/leds//trigger Date: March 2006 KernelVersion: 2.6.17 Contact: Richard Purdie rpurdie@rpsys.net Description: Set the trigger for this LED. A trigger is a kernel based source of led events. You can change triggers in a similar manner to the way an IO scheduler is chosen. Trigger specific parameters can appear in /sys/class/leds/ once a given trigger is selected.

What: /sys/class/leds//inverted Date: January 2011 KernelVersion: 2.6.38 Contact: Richard Purdie rpurdie@rpsys.net Description: Invert the LED on/off state. This parameter is specific to gpio and backlight triggers. In case of the backlight trigger, it is useful when driving a LED which is intended to indicate a device in a standby like state.
