9This sample show how to use the NXP MCUX Analog Comparator (ACMP) driver. The
10sample supports the :ref:`twr_ke18f`, :ref:`mimxrt1170_evk`.
11
12The input voltage for the negative input of the analog comparator is
13provided by the ACMP Digital-to-Analog Converter (DAC). The input voltage for
14the positive input can be adjusted by turning the on-board potentiometer for
15:ref:`twr_ke18f` board, for :ref:`mimxrt1170_evk` the voltage signal is
16captured on J25-13, need change the external voltage signal to check the
17output.
18
19The output value of the analog comparator is reported on the console.
