^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) 		a button which can be used to control the intensity of all the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7) 		LEDs at once, so that if they are too bright, user can dim them.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9) 		The microcontroller cycles between 8 levels of this global
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) 		brightness (from 100% to 0%), but this setting can have any
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) 		integer value between 0 and 100. It is therefore convenient to be
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) 		able to change this setting from software.
