Configuration

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:

• Heap is provided by the modm:platform:heap module.
• Tick is implemented via the modm:platform:clock module.
• LV_LOG_PRINTF = 0: logging is redirected to MODM_LOG_* if the modm:debug module is included and LV_USE_LOG = 1.

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:

Initialization

modm will call lv_init() as a constructor with priority 1000 and then set the required callbacks for the modm port to work. Static constructors are called afterwards therefore can already use the LVGL functions.
