| 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. |
