| :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. |
