Description
***********
.. code-block:: none
Input longpress pseudo-device
Listens for key events as an input and produces key events as output
corresponding to short and long press.
Can be optionally be associated to a specific device to listen for events
only from that device.
Example configuration:
#include <zephyr/dt-bindings/input/input-event-codes.h>
longpress {
input = <&buttons>;
compatible = "zephyr,input-longpress";
input-codes = <INPUT_KEY_0>, <INPUT_KEY_1>;
short-codes = <INPUT_KEY_A>, <INPUT_KEY_B>;
long-codes = <INPUT_KEY_X>, <INPUT_KEY_Y>;
long-delay-ms = <1000>;
};
Example output:
# short press
input event: dev=buttons SYN type= 1 code= 11 value=1 # INPUT_KEY_0 press
# release before one second
input event: dev=buttons SYN type= 1 code= 11 value=0 # INPUT_KEY_0 release
input event: dev=longpress SYN type= 1 code= 30 value=1 # INPUT_KEY_A press
input event: dev=longpress SYN type= 1 code= 30 value=0 # INPUT_KEY_A release
# long press
input event: dev=buttons SYN type= 1 code= 11 value=1 # INPUT_KEY_0 press
# hold for more than one second
input event: dev=longpress SYN type= 1 code= 45 value=1 # INPUT_KEY_X press
# wait for release
input event: dev=buttons SYN type= 1 code= 11 value=0 # INPUT_KEY_0 release
input event: dev=longpress SYN type= 1 code= 45 value=0 # INPUT_KEY_X release

input event: dev=longpress SYN type= 1 code= 45 value=0 # INPUT_KEY_X releaseInput long-press pseudo-device
입력 key event를 듣고 press duration에 따라 short 또는 long key event를 새로 생성합니다. input-codes, long-codes, long-delay-ms가 필수이고 short-codes는 선택입니다.
input을 제공하면 특정 device event만 듣고, 생략하면 모든 input device를 듣습니다.
input-codes의 원본 key
short-codes press + release 생성
long-codes press 생성
long-codes release 생성
공식 예는 1000 ms보다 일찍 놓으면 INPUT_KEY_A, 넘겨 유지하면 INPUT_KEY_X를 생성합니다. 배열 길이 불일치 처리 규칙은 이 schema에 명시되지 않습니다.
예제에는 compatible이 있지만 공식 property 표는 5개 node 항목뿐이고 base 표는 비어 있습니다. Compatible 행을 임의로 추가하지 않았습니다.
