:name: NXP MCUX Analog Comparator (ACMP)
:relevant-api: sensor_interface
Get analog comparator data from an NXP MCUX Analog Comparator (ACMP).
Overview
********
This sample show how to use the NXP MCUX Analog Comparator (ACMP) driver. The
sample supports the :ref:`twr_ke18f`, :ref:`mimxrt1170_evk`, :ref:`frdm_ke17z`
, :ref:`frdm_ke17z512` and :ref:`mimxrt1180_evk`.
The input voltage for the negative input of the analog comparator is
provided by the ACMP Digital-to-Analog Converter (DAC). The input voltage for
the positive input can be adjusted by turning the on-board potentiometer for
:ref:`twr_ke18f` board, for :ref:`mimxrt1170_evk` the voltage signal is
captured on J25-13, the :ref:`frdm_ke17z` and :ref:`frdm_ke17z512` boards are
captured in J2-3, the :ref:`mimxrt1180_evk` board are captured in J45-13, need
change the external voltage signal to check the output.
The output value of the analog comparator is reported on the console.
