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".
