When a pin is configured as an input is there an internal pull up resistor to Vdd
or does the input pin just float? thanks for your help

    There are no internal pullup resistors on the Propeller. The inputs will float without an external pullup or pulldown resistor.

    The input pins are input by default.
    is there an internal pull up resistor to Vdd
    or does the input pin just float?
    Can you tell us what you are trying to do? It depends on your app you planning to do. But, most apps you will need an pull up resistor to Vdd and if you have nothing connected to the I/O pin then you can just let it float

    thanks for the replies. I am trying to write a program in PropBasic to read a 4x4 keypad
