^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  2) --------------------------------------------------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  3) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  4) This LED Board (aka RED LEDs board) is widely used in
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  5) coffee vending machines produced by Crane Merchandising Systems.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) The board manages 3 LEDs and supports predefined blinking patterns
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7) for specific leds.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  8) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9) Vending area LED encoded with symbol 'V' (hex code 0x56).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) Doesn't have any hardware blinking pattern.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) Screen light tube LED which surrounds vending machine screen and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) encoded with symbol 'S' (hex code 0x53). Supports blinking breathing pattern.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) Water Pipe LED encoded with symbol 'P' (hex code 0x50) and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) actually consists of 5 LEDs that exposed by protocol like one LED.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) Supports next patterns:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) - cascade pattern
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) - inversed cascade pattern
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) - bounce pattern
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) - inversed bounce pattern
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22)
