Using the F877, I have PortA configured for analog inputs, and had 10K pots.
Seemed to work ok, I had a watch window set up, and a breakpoint right after
the read sequences (for 4 pots).

I've changed the pots to 50K now, and upped the aquisition time, but the
values seem to be way off now, and are affected by each other.

ie...

if I read just one, it is close...but not exact.  If I put the second pot in
the loop to read, the first one goes way off scale.  I've read the actual
voltages on the pins, and they are not changing.
Anyone ever seen where just reading a second port affects the value of the
first one?
