Vendor:

Zephyr Project

Driver:

subsys/input/input_double_tap.c

Description

Input double tap pseudo-device

Listens for key events as an input and produces key events as output
corresponding to double taps, and optionally to single taps.

Can optionally be associated to a specific device to listen for events
only from that device.

A single tap is reported once the double tap delay expires without a second
press, and only if the key has been released in the meantime, so that holding
a key down does not generate a single tap event.

Examples

#include <zephyr/dt-bindings/input/input-event-codes.h>

double_tap {
        input = <&buttons>;
        compatible = "zephyr,input-double-tap";
        input-codes = <INPUT_KEY_0>, <INPUT_KEY_1>;
        single-tap-codes = <INPUT_KEY_X>, <INPUT_KEY_Y>;
        double-tap-codes = <INPUT_KEY_A>, <INPUT_KEY_B>;
        double-tap-delay-ms = <300>;
};
