Masters:
@ dave-in-njthere is some Light going up here
need some time too let this sink in.
actually, you miised the point.
say you read A0 and is a 5 volts. and
then A1 and it is at 0.1 volts.
the buffer started at 5 and has to drain to 0.1
if you read
A1
A1
your first read of A1 will bring the buffer near to your reading.
the second time is will not have any of the values from the previous pin.
you did
A0
A1
A0
A1
no advantage in doing that.
however, if you are not experiencing any problems, then there is no need to do that at all.
