1What: /sys/class/leds/<led>/device/brightness2Date: July 20203KernelVersion: 5.94Contact: Marek Behún <kabel@kernel.org>5Description: (RW) On the front panel of the Turris Omnia router there is also6 a button which can be used to control the intensity of all the7 LEDs at once, so that if they are too bright, user can dim them.8 9 The microcontroller cycles between 8 levels of this global10 brightness (from 100% to 0%), but this setting can have any11 integer value between 0 and 100. It is therefore convenient to be12 able to change this setting from software.13 14 Format: %i15 16What: /sys/class/leds/<led>/device/gamma_correction17Date: August 202318KernelVersion: 6.619Contact: Marek Behún <kabel@kernel.org>20Description: (RW) Newer versions of the microcontroller firmware of the21 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 too25 old, the file always reads as 0, and writing to the file results26 in the EOPNOTSUPP error.27 28 Format: %i29
