    Hello , i am using the Button Class (Autor Raz Haleva) to read inputs and send the status to the MQTT Broker like:



    Button::Event event = buttons[button]->check();

    if (event == Button::Event::Down) { mqttClient.publish(buttonText[button], “Down”); }

    else if (event == Button::Event::Up) { mqttClient.publish(buttonText[button], “Up”); }


    For Controllino_AI0 to 9 it works fine but Controllino_AI10 or 11 it doesnt work. What is the difference between these both inputs? Also with the Controllino

    Best Regards Michael

    Hi Michael,

    please note that voltage divisor at screw terminals works as an internal pull-down resistor. So you shoud connect the button between the terminal and the supply voltage. Then it should work, but – you should not activate internal pull-ups in the microcontroller, and it will be inverted (HIGH when pushed, LOW when pulled).

    Best regards,
