But I too have spent time looking for things like this. A lot of the font data can be specific to the library or even a specific LCD memory layout (some are organized horizontally, some are vertically).<br><br>A couple tricks that I've found useful: <br><br>look for existing projects using the same LCD/library, they might have a font in there you can borrow. <br><br>or, when I got desparate, I just made my own. GCC for AVR chips supports the binary literal:<br><br>255 => 0xFF => 0b11111111<br><br>That can be helpful to create your own font if your memory layout is conducive to it.
