4-2 Modifying Resident Fonts
D e f i n i n g N e w C h a r a c t e r s
You must define each new character separately, performing the following
procedure for each one.
1. Define the character in a matrix. The matrix size depends on the font
you use (see “Resident Font Sizes”). Think of the matrix as a bitmap
showing the character’s design. Following is an example.
L e f t B y t e R i g h t B y t e
7 6 5 4 3 2 1 0 7 6 5 4 3 2 1 0
0
NOTE: Leave at least one column blank to the character’s right so
character strings do not run together.
2. Translate each line into two bit sequences (left byte/right byte), where
an empty square is 0, and a filled-in square is a 1. For example, the
second line from the top is 00000000 01000000.
3. Convert each bit sequence into two hex characters. For example, the
second line from the top is 00 40.
