+================================================================================
+                              GLASS LCD MAPPING
+================================================================================
+LCD allows to display informations on four 7-segment digits and 2 arrows:
+
+      1       2       3       4
+    -----   -----   -----   -----
+ /\ |   |   |   | o |   |   |   |
+    -- --   -- --   -- --   -- --
+ \/ |   |   |   | o |   |   |   |
+    ----- * ----- * ----- * -----
+
+LCD segment mapping:
+--------------------
+  -----A-----        _
+  |         |     L |_|
+  F         B
+  |         |        _
+  -----G-----     L |_|
+  |         |
+  E         C
+  |         |        _
+  -----D-----   DP  |_|
+
+ An LCD digir coding is based on the following matrix:
+COM           0   1
+SEG(n)      { E , G }
+SEG(n+1)    { D , F }
+SEG(23-n-1) { C , A }
+SEG(23-n)   { DP, B }
+with n positive odd number.
+
+The DIGIT '0' for example is:
+ -------------------------------
+LSB   { 1 , 0 }
+      { 1 , 1 }
+      { 1 , 1 }
+MSB   { 0 , 1 }
+     -------------------
+ 'A' =  7    E  hexa
