I am prototyping a load cell application based on PIC14000.
(internal single slope 16 bit A/D)
 Works well so far.
I have not done the calibration routines yet, though...
The temperature drift is significant, so even if y don«t need exact level I
will have to recaculate values against values measured from internal
bandgap reference.
