Maureen Helm e92df9c01d samples: Build hts221 sensor sample only on supported boards The hts221 sensor driver was implicitly made dependent upon the disco_l475_iot1 board when it was converted to dts, so build the associated sample only for this board. This issue was encountered when adding sensor dts support to nxp boards, which don't have hts221. Signed-off-by: Maureen Helm <maureen.helm@nxp.com>		2018-01-31 10:17:58 -06:00

HTS221: Temperature and Humidity Monitor
########################################

Overview
********
This sample periodically reads temperature and humidity from the HTS221
Temperature & Humidity Sensor and displays it on the console


Requirements
************

This sample uses the HTS221 sensor controlled using the I2C interface.

Building and Running
********************

 This project outputs sensor data to the console. It requires an HTS221
 sensor, which is present on the disco_l475_iot1 board.
