1 What: /sys/class/leds/<led>/device/brightness 2 Date: July 2020 3 KernelVersion: 5.9 4 Contact: Marek Behún <kabel@kernel.org> 5 Description: (RW) On the front panel of the Turris Omnia router there is also 6 a button which can be used to control the intensity of all the 7 LEDs at once, so that if they are too bright, user can dim them. 8 9 The microcontroller cycles between 8 levels of this global 10 brightness (from 100% to 0%), but this setting can have any 11 integer value between 0 and 100. It is therefore convenient to be 12 able to change this setting from software. 13 14 Format: %i 15 16 What: /sys/class/leds/<led>/device/gamma_correction 17 Date: August 2023 18 KernelVersion: 6.6 19 Contact: Marek Behún <kabel@kernel.org> 20 Description: (RW) Newer versions of the microcontroller firmware of the 21 Turris Omnia router support gamma correction for the RGB LEDs. 22 This feature can be enabled/disabled by writing to this file. 23 24 If the feature is not supported because the MCU firmware is too 25 old, the file always reads as 0, and writing to the file results 26 in the EOPNOTSUPP error. 27 28 Format: %i
