Detailed Description

Button configuration.

All fields have sensible defaults, but you must set pin and callback at minimum.

idfxx::button btn({
.pin = idfxx::gpio_4,
.callback = [](idfxx::button::event_type ev) {
if (ev == idfxx::button::event_type::clicked) {
// handle click
}
},
});
idfxx::button
GPIO push-button with debounce, click, long press, and autorepeat support.
Definition button.hpp:38
idfxx::button::event_type
event_type
Button event type.
Definition button.hpp:62
idfxx::button::event_type::clicked
@ clicked
