GLASS LCD MAPPING
================================================================================
LCD allows to display informations on six 14-segment digits and 4 bars:
1 2 3 4 5 6
----- ----- ----- ----- ----- -----
|\|/| o |\|/| o |\|/| o |\|/| o |\|/| |\|/| BAR3
-- -- -- -- -- -- -- -- -- -- -- -- BAR2
|/|\| o |/|\| o |/|\| o |/|\| o |/|\| |/|\| BAR1
----- * ----- * ----- * ----- * ----- ----- BAR0
LCD segment mapping:
--------------------
-----A----- _
|\ | /| COL |_|
F H J K B
| \ | / | _
--G-- --M-- COL |_|
| / | \ |
E Q P N C
|/ | \| _
-----D----- DP |_|
An LCD character coding is based on the following matrix:
COM 0 1 2 3
SEG(n) { E , D , P , N }
SEG(n+1) { M , C , COL , DP }
SEG(23-n-1) { B , A , K , J }
SEG(23-n) { G , F , Q , H }
with n positive odd number.
The character 'A' for example is:
-------------------------------
LSB { 1 , 0 , 0 , 0 }
{ 1 , 1 , 0 , 0 }
{ 1 , 1 , 0 , 0 }
MSB { 1 , 1 , 0 , 0 }
-------------------
'A' = F E 0 0 hexa
