Gerard Marull-Paretas a202341958 devices: constify device pointers initialized at compile time Many device pointers are initialized at compile and never changed. This means that the device pointer can be constified (immutable). Automated using: ``` perl -i -pe 's/const struct device \(?!const)(.)= DEVICE/const struct device const $1= DEVICE/g' /.c ``` Signed-off-by: Gerard Marull-Paretas <gerard.marull@nordicsemi.no>		2022-08-22 17:08:26 +02:00

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:
