- Description: (RW) On the front panel of the Turris Omnia router there is also
- a button which can be used to control the intensity of all the
- LEDs at once, so that if they are too bright, user can dim them.
- The microcontroller cycles between 8 levels of this global
- brightness (from 100% to 0%), but this setting can have any
- integer value between 0 and 100. It is therefore convenient to be
- able to change this setting from software.
