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 192 ROM fixed codes.
1.) The command "CG RAM Address Set"
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.
2.) Doing 8 times the write command
"Data Write" defines line by line the
new character. 8th. byte stands for the
cursor line.
3.) The new defined character can be
used as a "normal" ASCII code (0..7); use with "DD RAM Address Set" and "Data Write".
