Rework to change the thermistor from single-ended mode to ratio-metric differential mode.
−
By default, the thermistor is connected in single-ended mode to P2[6] and this can be changed to ratio-
metric differential mode by modifying zero-ohm resistor connections. The optional pins provided for
ratio-metric mode are also connected to Arduino header (J2). Remove these resistors while connecting
the thermistor in ratio-metric mode.
−
Remove R66, R73, R91 and load same on R64, R71, and R88.
