lbuild module: modm:lvgl

LVGL is a free and open-source graphics library providing everything you need to create embedded GUI with easy-to-use graphical elements, beautiful visual effects and low memory footprint.


LVGL defines defaults for all it's configuration settings, which you can find in the configuration template.

This module generates a lv_conf.h file to define the options necessary for integration with modm which are:

To add your own configuration you can create a <lv_conf_local.h> file which will automatically be included at the beginning of our lv_conf.h.

Example <lv_conf_local.h> configuration:

// Maximal resolutions
#define LV_HOR_RES_MAX 240
#define LV_VER_RES_MAX 320
#define LV_DPI 200
/* Color depth:
- 1: 1 byte per pixel
- 8: RGB332
- 16: RGB565
- 32: ARGB8888
#define LV_COLOR_DEPTH 16
// Enable logging at INFO level
