Torsten Rasmussen 1cccc8a8fe cmake: increase minimal required version to 3.20.0 Move to CMake 3.20.0. At the Toolchain WG it was decided to move to CMake 3.20.0. The main reason for increasing CMake version is better toolchain support. Better toolchain support is added in the following CMake versions: - armclang, CMake 3.15 - Intel oneAPI, CMake 3.20 - IAR, CMake 3.15 and 3.20 Signed-off-by: Torsten Rasmussen <Torsten.Rasmussen@nordicsemi.no>		2021-08-20 09:47:34 +02:00

.. _cfb_custom_fonts:

Custom Fonts
############

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/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:

   :zephyr-app: samples/display/cfb_custom_font
   :host-os: unix
   :board: reel_board
