9This sample is provided as an example of how to read the temperature
10of a Resistance Temperature Detector (RTD) sensor using the LMP90100
11Sensor AFE Evaluation Board shield. The sample is designed for use
12with a 3-wire PT100 sensor.

17Requirements
18************
19
20Prior to running the sample application, the LMP90100 EVB must be
21connected to the development board according to Example #3 ("3-wire
22RTD Application") in the `LMP90100 Sensor AFE Evaluation Board User's
23Guide`_.

25Building and Running
26********************
27
28This sample runs with the LMP90100 EVB connected to any development
29board with a matching Arduino connector. For this example, we use a
30:ref:`frdm_k64f` board.
