Does anyone know how to set a pin to float after setting it high or low?

Thanks,

Alina

    Set that pin as input.

    Assuming you are using a BS2, change the "dirs" (direction setting)
    for that pin from output to input. Then remember to change it back
    again if you need it to assert a LOW or HIGH later in the program.

    Don't HIGH and LOW make the pin an output, then set the state?

    Yes, HIGH and LOW both set the associated DIRS bit to make the pin an output.
