operation is no longer required.
CREATING YOUR OWN CHARACTERS
All these character display modules got the feature to create 8 own characters (ASCII Codes 0..7) in
addition to the 240 ROM fixed codes.
1.) The command "CG RAM Address Set"
2.) Doing 8 times the write command "Data
3.) The new defined character can be used

defines the ASCII code (Bit 3,4,5) and the
dot line (Bit 0,1,2) of the new character.
Example demonstrates creating ASCII
code $00.
Write" defines line by line the new
character. 8th. byte stands for the cursor
line.
as a "normal" ASCII code (0..7); use with "DD RAM Address Set" and "Data Write".
