Layout and definition of the special characters
The FB enables the definition of 7 special characters. It is possible to assign an individual ASCII code
to each of these special characters.
·
The 5 x 7 matrix of a character is defined via the array variable abyCharMap. Each array
element of data type byte is bit−coded and represents one column of the matrix
(0 = white pixel, 1 = black pixel).
·
The array variable abyCharCode is used to define the ASCII codes for the special characters.
Example:
Define a "
m
" as second special character under ASCII code "200":
0
1

abyCharMap[9] = 2#00000000
abyCharMap[8] = 2#01111110
abyCharMap[7] = 2#00010000
abyCharMap[6] = 2#00001110
abyCharMap[5] = 2#00000000
abyCharCode[1] = 200

Assignment of the array index [0...30] to the matrix column
Note!
·
If special characters are defined under ASCII codes between 32 and 127 the special
characters will be indicated instead of the standard ASCII characters.
·
The defined special characters are only transferred to the strings pString1 ... pString4 if
bUpdateCharCodeMap is set to TRUE.
