Fonts

Generated with https://lvgl.io/tools/fontconverter. Your best bet is finding a .tff file from google fonts. Using compression on a .c file appears to have issues.

Adding a custom font to the binary:

highlevel

  • Create lv_font_my_26.c using tool above
  • add font to lvgl/src/font submodule
  • update lv_conf.h with #define LV_FONT_CUSTOM_DECLARE LV_FONT_DECLARE(lv_font_my_26) If needed you can turn off montserrat fonts, and set a new default font.
  • Build and import using lv.font_my_26

Example lv_conf.h

/*Optionally declare custom fonts here.
 *You can use these fonts as default font too and they will be available globally.
 *E.g. #define LV_FONT_CUSTOM_DECLARE   LV_FONT_DECLARE(my_font_1) LV_FONT_DECLARE(my_font_2)*/
#define LV_FONT_CUSTOM_DECLARE LV_FONT_DECLARE(lv_font_inter_16) LV_FONT_DECLARE(lv_font_inter_20) LV_FONT_DECLARE(lv_font_inter_28) LV_FONT_DECLARE(lv_font_inter_36)

/*Always set a default font*/
// #define LV_FONT_DEFAULT &lv_font_montserrat_14
#define LV_FONT_DEFAULT &lv_font_inter_16
