    Dear,

    I am having hard time connecting a DS18b20 temperature sensor to mDot.

    …

    EDIT: my bad, wrong connections.

    Hi Kaz,

    I think the issue is with your probe pin. D13 is not a defined pin for the mDot. Pin PA_5 of the mDot routes to D13 on the UDK2 board. If you look at the PinNames.h file in the path mbed-os\targets\target_stm\target_stm32f4 you’ll see that PA_5 can also be referenced as XBEE_AD2 and XBEE_DIO2.

    If that does not solve it, I’d suggest you verify that you have control of the correct pin by setting it as either a digitalin or digitalout then read or set levels and confirm.

    Kind regards,
    Leon
