You can use the [[Tools LCD Designer|LCD designer]] to build the characters.

 

It is important that a CLS follows the DEFLCDCHAR statement(s).

So make sure you use the DEFLCDCHAR before your CLS statement.

 

Special characters can be printed with the [[CHR|Chr]]() function.

 

LCD Text displays have a 64 byte memory that can be used to show your own custom characters. Each character uses 8 bytes as the character is an array from 8x8 pixels. You can create a maximum of 8 characters this way. Or better said : you can show a maximum of 8 custom characters at the same time. You can redefine characters in your program but with the previous mentioned restriction.

A custom character can be used to show characters that are not available in the LCD font table. For example a Û.

You can also use custom characters to create a bar graph or a music note.

= Partial Example =

 <source lang="bascomavr">
Deflcdchar 1 , 225 , 227 , 226 , 226 , 226 , 242 , 234 , 228 ' replace ? with number (0-7)
Deflcdchar 0 , 240 , 224 , 224 , 255 , 254 , 252 , 248 , 240 ' replace ? with number (0-7)
Cls 'select data RAM
Rem it is important that a CLS is following the deflcdchar statements because it will set the controller back in datamode
Lcd Chr(0) ; Chr(1)
