10This sample show how to use the NXP MCUX Analog Comparator (ACMP) driver. The
11sample supports the :zephyr:board:`twr_ke18f`, :zephyr:board:`mimxrt1170_evk`, :zephyr:board:`frdm_ke17z`
12, :zephyr:board:`frdm_ke17z512` and :zephyr:board:`mimxrt1180_evk`.
13
14The input voltage for the negative input of the analog comparator is
15provided by the ACMP Digital-to-Analog Converter (DAC). The input voltage for
16the positive input can be adjusted by turning the on-board potentiometer for
17:zephyr:board:`twr_ke18f` board, for :zephyr:board:`mimxrt1170_evk` the voltage signal is
18captured on J25-13, the :zephyr:board:`frdm_ke17z` and :zephyr:board:`frdm_ke17z512` boards are
19captured in J2-3, the :zephyr:board:`mimxrt1180_evk` board are captured in J45-13, need
20change the external voltage signal to check the output.
21
22The output value of the analog comparator is reported on the console.
