.. _mcux_acmp: 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` and :ref:`frdm_ke17z512`. 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, need change the external voltage signal to check the output. The output value of the analog comparator is reported on the console.
