button's Issues

Example Usage?

Thank you for sharing this component. Do you happen to have any example usage code? If not, I can help create some for quicker usage.

GPIO isr service is already installed

Hello, I am trying to use your component and am encountering strange behavior.
When I use "button_init" more than once, I get the error E(343) gpio: gpio_install_isr_service(498): GPIO isr service is already installed.
The callback is triggered only by the last initialized button.
What's wrong?

The code snippet is attached below:

    button_t button2;
    button_t button3;

                                tskIDLE_PRIORITY + 11,
                                configMINIMAL_STACK_SIZE * 4));

    ESP_ERROR_CHECK(button_init(&button2,

    button_add_cb(&button2, BUTTON_CLICK_SINGLE, button1_cb, "Button 2 single click");
