Create MPLAB Harmony v3 Project Using MPLAB X IDE

Select File > New Project from the main IDE menu.

Close all existing opened projects before you start creating a new project.

In the Categories pane of the New Project dialog window, select Microchip Embedded. In the Projects pane, select 32-bit MCC Harmony Project, then click Next.

32-bit MCC Harmony Project

If 32-bit MPLAB Harmony 3 Project is not displayed, you will need to install MCC.

In the Framework Path edit box, browse to the folder you downloaded the framework to. If you haven't done this, or want to download it to a different folder, click the Launch Content Manager button, then click Next.

For more information on the content manager, see the MPLAB Code Configurator Overview page.

Framework Path edit box

In the Project Settings window, apply the following settings:

  • Location: indicates the path to the root folder of the new project. All project files will be placed inside this folder. The project location can be any valid path, for example: C:\microchip\harmony\v3\training\dev.
  • Folder: indicates the name of the MPLABX .X folder. Enter "pic32mx470_curiosity" to create a pic32mx470_curiosity.X folder.

This must be a valid directory name for your operating system.

  • Name: enter the project’s logical name as "getting_started_pic32mx470_curiosity". This is the name that will be shown from within the MPLAB X IDE.

The Path box is read-only. It will update as you make changes to the other entries.

  • Click Next to proceed to configuration settings.
