Description: read/write
|
|
Writing to this file will update all LEDs within the group to a
|
|
calculated percentage of what each color LED intensity is set
|
|
to. The percentage is calculated for each grouped LED via the
|
|
equation below:
|
|
|
|
led_brightness = brightness * multi_intensity/max_brightness
|
|
|
|
For additional details please refer to
|
|
Documentation/leds/leds-class-multicolor.rst.
|
|
|
|
The value of the LED is from 0 to
|
|
/sys/class/leds/<led>/max_brightness.

The multi_index array, when read, will output the LED colors
|

multi_intensity file.

Description: read/write
|
|
This file contains array of integers. Order of components is
|
|
described by the multi_index array. The maximum intensity should
|
|
not exceed /sys/class/leds/<led>/max_brightness.
