Detailed Description

The system font objects are globaly available for a graphical application. System fonts are by design read only, hence there are not any functions to change them during runtime. If the application needs additional fonts it should add additional font objects.

Variable Documentation

struct font sysfont

Initial value:

 {
        .type           = FONT_LOC_PROGMEM,
        .width          = SYSFONT_WIDTH,
        .height         = SYSFONT_HEIGHT,
        .scale          = 1,
        .first_char     = SYSFONT_FIRSTCHAR,
        .last_char      = SYSFONT_LASTCHAR,
        .data           = {
                .progmem        = sysfont_glyphs,
        },
}

Initialize a basic system font.

This initializes a basic system font globally usable by the application.
