Zephyr Input GPIO KEYS parent node
|
|
|
|
This defines a group of buttons that can generate input events. Each button
|
|
is defined in a child node of the gpio-keys node and defines a specific key
|
|
code.
|
|
|
|
For example:
|
|
|
|
#include <zephyr/dt-bindings/input/input-event-codes.h>
|
|
|
|
/ {
|
|
buttons {
|
|
compatible = "gpio-keys";
|
|
button_0 {
|
|
gpios = <&gpio0 13 (GPIO_PULL_UP | GPIO_ACTIVE_LOW)>;
|
|
zephyr,code = <INPUT_KEY_0>;
|
|
};
|
|
};
|
|
};
|
|
|
|
|
|
compatible: "gpio-keys"
|
|
|
|
include: base.yaml
|
|
|
|
properties:
|
|
debounce-interval-ms:
|
|
type: int
|
|
default: 30
|
|
description: |
|
|
Debouncing interval time in milliseconds.
|
|
If not specified defaults to 30.
|
|
|
|
polling-mode:
|
|
type: boolean
|
|
description: |
|
|
Do not use interrupts for the key GPIOs, poll the pin periodically at the
|
|
specified debounce-interval-ms instead.
