The voltage-divider is made up of 2 resistors -- one is the temp sensor=20
(ground to center) and the other is a fixed value (+5V to center).  Depen=
ding=20
on what range I need (still undetermined), I'll pick a fixed resistor to =
get=20
maximum voltage-range into the PIC A/D input.  That will determine the ac=
tual=20
current flow and thus the amount of self-heating.

Cheers,
-Neil.
