here you can download a simple Custom Character editor (using $CustomChar command). LINK TO FILE
The main idea was to build a app that is able to edit more than one character. Now you can put any logo on your LCD Display.
First release is provided for two-line displays... maybe later (if you want or need it, of course) I will make some advantages for bigger displays.
Now, enjoy and say what you think about this plug.
Thanks.
