LMP90100 Sensor AFE Evaluation Board: RTD Sample
|
|
################################################
|
|
|
|
Overview
|
|
********
|
|
|
|
This sample is provided as an example of how to read the temperature
|
|
of a Resistance Temperature Detector (RTD) sensor using the LMP90100
|
|
Sensor AFE Evaluation Board shield. The sample is designed for use
|
|
with a 3-wire PT100 sensor.
|
|
|
|
Please refer to :ref:`lmp90100_evb_shield` for more information on
|
|
this shield.
|
|
|
|
Requirements
|
|
************
|
|
|
|
Prior to running the sample application, the LMP90100 EVB must be
|
|
connected to the development board according to Example #3 ("3-wire
|
|
RTD Application") in the `LMP90100 Sensor AFE Evaluation Board User's
|
|
Guide`_.
|

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