History

Torsten Rasmussen 407b49b35c cmake: use find_package to locate Zephyr Using find_package to locate Zephyr. Old behavior was to use $ENV{ZEPHYR_BASE} for inclusion of boiler plate code. Whenever an automatic run of CMake happend by the build system / IDE then it was required that ZEPHYR_BASE was defined. Using ZEPHYR_BASE only to locate the Zephyr package allows CMake to cache the base variable and thus allowing subsequent invocation even if ZEPHYR_BASE is not set in the environment. It also removes the risk of strange build results if a user switchs between different Zephyr based project folders and forgetting to reset ZEPHYR_BASE before running ninja / make.

ams ens210 Relative Humidity and Temperature Sensor
###################################################

Overview
********

This sample application demonstrates how to use the ams ens210 sensor to
measure the ambient temperature and relative humidity.

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

This sample application uses the sensor connected to the i2c stated in the
ens210.overlay file.
Flash the binary to a board of choice with a sensor connected.
For example build for a nucleo_f446re board:

.. zephyr-app-commands::
   :zephyr-app: samples/sensor/ens210
   :board: nucleo_f446re
   :goals: build flash
   :compact:
