THERMISTOR.C
for display to the Dynamic C
thermistor is the one included in the Development Kit whose values for beta, series
resistance, and resistance at standard temperature are given in the part specification.
Install the thermistor at location JP25 on the Prototyping Board before running this
sample program. Observe the temperature changes shown in the Dynamic C
window as you apply heat or cold air to the thermistor.
