:name: Custom fonts
:relevant-api: monochrome_character_framebuffer
Generate and use a custom font.
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.
The source code for this sample application can be found at:
:zephyr_file:`samples/subsys/display/cfb_custom_font`.
Building and Running
********************
There are different configuration files in the cfb_custom_font
directory:
- :file:`prj.conf`
Generic config file, normally you should use this.
- :file:`boards/reel_board.conf`
This overlay config enables support for SSD16XX display controller
on the reel_board.
Example building for the reel_board with SSD16XX display support:
