    Default Beware the PULSOUT inversion problem

    PULSOUT is a toggle. Sooner or later you will get some interference that flips the state of the SERVOOUT line and your system will be off in the weeds.

    To guarantee correct working of the PULSOUT command you should first force the SERVOOUT line to a defined state.

    For example, put
    SERVOOUT = 0
    or
    LOW SERVOOUT
    before calling the Pulsout command.

    One of my RC aircraft went berserk because of that little oversight.

    You mean like pulling UP out of an inverted low pass?
    I lost a hopped-up clipped wing (+an extra bay) Goldberg Cub that way....(sigh)....

    Hi, BrianT

    To fullfill your Pulsout knowledge ...

    You are to use LOW Output ...

    with some Hot plugged servos ( Graupner i.e.) or High capacitive loads ( some µF ) , Output = 0 is not enough to have a neat O level prior to Pulsin.
    I know it's not supposed to happen in flight ... but, ...

    Service,Sir ...

    Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

    IF there is the word "Problem" in your question ...
    certainly the answer is " RTFM " or " RTFDataSheet " !!!
