Overview
|
|
|
|
|
********
|
|
|
|
|
A simple example showing how to generate Character Framebuffer (CFB)
|
|
|
|
|
font headers automatically at build time.
|
|
|
|
|
|
|
|
|
|
This example generates a font with font elements for 6 sided dice from
|
|
|
|
|
a PNG image, and then uses the generated header (``cfb_font_dice.h``)
|
|
|
|
|
to show the font elements on the display of a supported board.
