Figure 2. Circuit Diagram of the RTD Circuit
Using the sample code in \code\adc\pot.c, the variation
in the potentiometer resistance can be seen on the out-
put LED. Note that the internal reference and the external
reference are 2.5 V, which gives an ADC input range of
0 V to 2.5 V in single-ended mode. The potentiometer
can give a voltage between 0 V and AV
DD
= 3.3 V.
