Enabling Hardware Trigger-Based ADC Input Sampling for PWM Duty Cycle Control-with FRDM-MCXA156

[#1]

This document introduces how to configure and use the hardware trigger feature of the Analog-to-Digital Converter (ADC) on the FRDM-MCXA156 development board.

It presents an event where using an external button initiates a reading and ADC conversion that reads an analog input from a potentiometer; the resulting digital value is then used to dynamically update the duty cycle of a PWM signal connected to an external output represented by a LED.

This example demonstrates the usage of external connections and analog measurement by walking through the modifications required to enable hardware triggering via the Input Multiplexing (INPUTMUX) module.
