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
