I have the chip 2P40. i have the following:

output 16


MOTOR2_C VAR OUT16

and get the error undefined symbol on the second line just trying to setup an
alias.

does this error have to to with the fact one side ofthe chip is IO the other
side is AUX????

TIA.

    There IS NO 'OUT16', they max out at 'OUT15',
    so the compiler complains.

    There IS a 'pseudo-pin' 16, which refers to
    the SIN/SOUT port, which is why 'output 16' doesn't
    complain. I don't know the command to switch to
    the 'X' ports -- anybody know it?
    (Could search the Forum for 'X15')

    You can use the "pseudo" ports 16 for serial input / output, but not for
    normal input / output control.
    eg...

    serin 16, etc etc

    OOps,
    I think Ianswered the question a bit fast.

    You should read the help for mainio and auxio for the bs2p40 i/o access.
    I think you need to switch to auxio and then access pin 0 to access physical
    pin 16.

    Cheers,
    Chris

    BS2p40 pins are in two banks: MAINIO and AUXIO. Both banks use pin
    numbers 0 to 15. To get to pin 0 on the auxilliary bank, you would do
    this:

    AUXIO
    OUTPUT 0

    To get back to the main bank ...

    MAINIO
    OUTPUT 0
