|
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.
