1. Copy `lv_conf_templ.h` as `lv_conf.h` next to `lvgl` and set at least `LV_HOR_RES`, `LV_VER_RES` and `LV_COLOR_DEPTH`. 1. Copy `lv_conf_templ.h` as `lv_conf.h` next to `lvgl` and set at least `LV_HOR_RES`, `LV_VER_RES` and `LV_COLOR_DEPTH`.
2. Call `lv_tick_inc(x)` every `x` milliseconds **in a Timer or Task** (`x` should be between 1 and 10). It is required for the internal timing of LittlevGL. 2.
