This is simple "GUI" to create your own font to use with lcdmod (for HD44780 displays); just "draw" your font using checkboxes below and enter "submit". This will generate a string you have to pass to your lcd (you can just copy-paste). Don't forget to change the font index to apropriate number (the number after R) - from 0 to 7.
