Button button;

void buttonPressed()
{
    Serial.println("Button has been pressed 🤠");
}

void setup()
{
    Serial.begin(9600);

    // The 1st parameter: the pin connected with the button
    // The 2nd parameter: the debouncing period [35-40 ms is recommended]
    // The 3rd parameter: true or false [default logic is high?]
    // The 4th parameter: true or false [with internal Pull Up?]
    button.init(Pin(PortB, 5), 40, false, false);
    button.pressed = buttonPressed; // set the handler
}

void loop()
{
    button.refresh(); // important
}
