.. zephyr:code-sample:: mcux_acmp :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 :zephyr:board:`twr_ke18f`, :zephyr:board:`mimxrt1170_evk`, :zephyr:board:`frdm_ke17z` , :zephyr:board:`frdm_ke17z512` and :zephyr:board:`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 :zephyr:board:`twr_ke18f` board, for :zephyr:board:`mimxrt1170_evk` the voltage signal is captured on J25-13, the :zephyr:board:`frdm_ke17z` and :zephyr:board:`frdm_ke17z512` boards are captured in J2-3, the :zephyr:board:`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.
