This example is constructed by [IDF component manager](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/tools/idf-component-manager.html), all the external dependency will be handled by the CMake build system automatically. In this case, it will help download the lvgl from the [ESP Component Registry](https://components.espressif.com/component/lvgl/lvgl), with the version specified in the [manifest file](main/idf_component.yml).
This example uses the [esp_timer](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/system/esp_timer.html) to generate the ticks needed by LVGL and uses a dedicated task to run the `lv_timer_handler()`. Since the LVGL APIs are not thread-safe, this example uses a mutex which be invoked before the call of `lv_timer_handler()` and released after it. The same mutex needs to be used in other tasks and threads around every LVGL (lv_...) related function call and code. For more porting guides, please refer to [LVGL porting doc](https://docs.lvgl.io/master/porting/index.html).
