Getting Started with MPLAB® Harmony v3 to Create a Web-Enabled Digital Photo Frame

Introduction

MPLAB® Harmony is a flexible firmware development platform for PIC32 microcontrollers. This integrated software framework provides driver libraries and APIs that make it easier to use PIC32 peripherals (timers, GPIO, UART, I2C, SPI, etc.). It also includes middleware libraries for USB (host and device), TCP/IP (Ethernet and Wi-Fi®), graphics, Bluetooth®, and others.

This tutorial is intended to show users how to create a web-enabled digital photo frame from scratch using MPLAB Harmony 3 and MPLAB Code Configurator (MCC) with Harmony 3. The project you create will run on the Curiosity PIC32MZ EF 2.0 Development Board (DM320209). This application will perform the following tasks:

  • The photos will be hosted on the microSD Click board™ mounted on the mikroBUS™ 1 of the Curiosity 2.0 board.
  • Display photos from the SD card using the High-Performance 4.3" WQVGA Display Module with maXTouch® (AC320005-4) technology and the SSD1963 LCD Controller Graphics Card (AC320214).
  • Host an onboard webserver to display the same photos using your computer's web browser, using the TCP/IP stack on the PIC32MZ2048EFM144, where the Ethernet MAC mounted is connected via RMII, with KSZ8061 Daughter Board (AC320004-6) mounted on the Ethernet PHY Module of the Curiosity 2.0 board.
  • Console using the MCP2221 USB-to-UART/I2C converter from MikroElektronika (USB I2C Click).
