    Default Re: limiting to "no less than" zero

    I'd figured as much (on account everyone was doing it!)....can the default be changed to 0? (I'd imagine that switches get used with weak pullups or external pullups ....so the switch pressed condition would be a 0).

    Re Darrel's entry..

    Code:
    if volume.15 then volume = 0 ; zero if it went negative
    how does bit 15 of 'volume' being a '1' indicate negative? Can someone shine a little more light on this one please?
