Detailed Description

Predefined LVGL keys for use in Devicetree.

Used in the lvgl-codes property of a zephyr,lvgl-keypad-input node to map input event codes to LVGL keys. Values mirror enum _lv_key_t from LVGL's lv_group.h.

Example devicetree usage:

#include <zephyr/dt-bindings/input/input-event-codes.h>
#include <zephyr/dt-bindings/lvgl/lvgl.h>
 
keypad {
        compatible = "zephyr,lvgl-keypad-input";
        input = <&buttons>;
        input-codes = <INPUT_KEY_1 INPUT_KEY_2>;
        lvgl-codes = <LV_KEY_NEXT LV_KEY_PREV>;
};
