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

SM351LT: Magnetoresistive Sensor Example
########################################

Overview
********

This sample application periodically polls an SM351LT magnetoresistive sensor
and displays if a magnet near to the sensor, via the console.

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

This sample uses the Honeywell SM351LT sensor.
