| 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. | |
