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

NPCX ADC Comparator
###################

Overview
********

This sample show how to use the NPCX ADC Comparator driver. The
sample supports the :ref:`npcx9m6f_evb`.

This application is a voltage comparator with hysteresis, upper limit is
set at 1 V while lower limit is 250 mV. Initially configured to detect
upper limit.

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

Build the application for the :ref:`npcx9m6f_evb` board, and provide voltage
to ADC channel 8, when voltages cross upper/lower limits, detection messages
will be printed.
