    Or might be because PIN 16 is not a valid pin , funny I have never used PINs always used PortA, PortB etc . . less confusing I guess . . . anyway only 0-15 are valid: SEC. 4.11. PINS

    HenrikOlsson and Joe are saying change your code from
    Code:
    Serin 16,16780,[WAIT(255),PinNumber,PinState]
    to
    Code:
    SERIN2 PORT?.?,16780,[WAIT(255),PinNumber,PinState]
    Seems to work much better using for example:
    PORTC.3
    instead of
    PIN?

    Please note the information on Bruce's website prior to the code for this example:

    For simplicity I am going to use a Basic Stamp II to receive the data and act accordingly to the data. You will need to hook up the Basic Stamp II just like you are going to program it and use the programming port (pin 16) for communications. Program the Basic Stamp II with the following code...
    That's probably where there is some confusion.
