PIC32MZ W1 Software User’s Guide

Introduction

This document describes the software features supported by the PIC32MZ W1 Family using the MPLAB

® Harmony

v3 framework. This framework is integrated with a development environment that works directly with the WFI32E01

module. The software release package enables a rich set of PIC32MZ1025W104 SoC features such as 802.11 b/g/n,

Ethernet, USB, CAN, CAN-FD, SPI, I2C, SQI, UART and JTAG, which are supported by the PIC32MZ W1 Family.
