.. zephyr:code-sample:: cfb-custom-fonts :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: .. zephyr-app-commands:: :zephyr-app: samples/subsys/display/cfb_custom_font :host-os: unix :board: reel_board :goals: flash :compact:
