- An LCD character coding is based on the following matrix:\r
- { E , D , P , N }\r
- { M , C , COL , DP}\r
- { B , A , K , J }\r
- { G , F , Q , H }\r
-\r
- The character 'A' for example is:\r
- -------------------------------\r
-LSB { 1 , 0 , 0 , 0 }\r
- { 1 , 1 , 0 , 0 }\r
- { 1 , 1 , 0 , 0 }\r
-MSB { 1 , 1 , 0 , 0 }\r
- -------------------\r
