Introduction

A high CPU load can be caused by using interrupts to manage a large number of ADC conversions across multiple channels and transferring the resulting data from peripheral registers to a user buffer. With the help of an Event System and a DMA, the data can be transferred to the specified memory location without the intervention of the CPU.

This document describes how to configure and use the ADC peripheral library in MPLAB® Harmony v3 with the timer, Event System (EVSYS), and DMA data transfer features.
