|
|
Overview
|
|
********
|
|
|
|
This sample show how to use the NXP MCUX Analog Comparator (ACMP) driver. The
|
|
sample supports the :ref:`twr_ke18f`, :ref:`mimxrt1170_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
|
|
:ref:`twr_ke18f` board, for :ref:`mimxrt1170_evk` the voltage signal is
|
|
captured on J25-13, need change the external voltage signal to check the
|
|
output.
|
|
|
|
The output value of the analog comparator is reported on the console.

==================================
|
|
Build the application for the :ref:`twr_ke18f` board, and adjust the
|
|
ACMP input voltage by turning the on-board potentiometer.

Building and Running for MIMXRT1170-EVK
|
|
=======================================
|
|
Build the application for the MIMXRT1170-EVK board, and adjust the
|
|
ACMP input voltage by changing the voltage input to J25-13.
