Anas Nashif 3ae52624ff license: cleanup: add SPDX Apache-2.0 license identifier Update the files which contain no license information with the 'Apache-2.0' SPDX license identifier. Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of Zephyr, which is Apache version 2. Signed-off-by: Anas Nashif <anas.nashif@intel.com>		2019-04-07 08:45:22 -04:00

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 SSD1673 display controller
  on the reel_board.


Example building for the reel_board with SSD1673 display support:

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