In the absence of a physical device to test the software with I had
to errr on the side of caution, because although the sockets aren't
multiplexed, they use fast PWM in things like the fade routine, which
is similar to muxing when looked at in terms of switching.
I didn't have aproblem with the B7971's wiht this system and am quite
sure the ZM1350 will be just as good as that and not need the keep
alive, but it's there for now, just in case.
Perhaps after all I'll leave the tracks there because now that I've
looked at it a second time, removing that resistor will not make the
board any smaller.
