LVGL keypad indev pseudo-device
|
||
|
|
|
||
|
|
Listens for input events and routes the
|
||
|
|
lv_indev_data_t to the underlying keypad lv_indev_t managed by LVGL.
|
||
|
|
|
||
|
|
The property input-codes can be used to setup a mapping of input codes
|
||
|
|
to the lvgl keys. There are lvgl keys that have a special function:
|
||
|
|
https://docs.lvgl.io/master/overview/indev.html#keys.
|
||
|
|
|
||
|
|
The pseudo device can be associated to a specific device to listen only
|
||
|
|
for events from that device. Example configuration:
|
||
|
|
|
||
|
|
#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>;
|
||
|
|
};
