Last modified by Microchip on 2023/11/09 09:07

Install the MPLAB® Harmony Configurator (MHC) Plug-in in the MPLAB X IDE or verify that MHC is installed.

Launch MPLAB X IDE from the Windows® Start Menu. Close any projects and files that are currently open.

Go to Tools > Embedded.

You will see MPLAB Harmony 3 Configurator in the menu. If you don't see it in the menu, please install MHC.

Go to Plugins > Window Manager and select Standalone mode. Click Apply and then click OK.

Plugins > Window Manager

When you launch MHC for the first time, it displays a prompt asking for the mode in which you would like to use MHC.

  • Standalone mode (as a separate window)
  • Native mode (as an embedded window in MPLAB X)
    Standalone mode is the default mode.

MHC will launch in the operating mode selected the first time, every time you launch MHC. Step 1.2 above shows a way to change the MHC operating mode.

For this lab, MHC is configured to operate in Standalone mode.

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 MPLAB Harmony 3 Project, then click Next.

Categories pane of the New Project dialog window

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

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 "Microchip MPLAB Harmony" 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.

New Project window

Clicking on the Show Visual Help button will open a help window, providing a detailed description of the various fields in the Project Settings window.

New Project Wizard Help

Follow the steps below to set the project’s configuration settings:

  • Name: enter the configuration name as "pic32mx470_curiosity".
  • Target Device: select PIC32MX470F512H as the target device.

You can select the Device Family or enter a partial device name to filter the list in Target Device in order to make it easier to locate the desired device.

  • After selecting the target device, click Finish to launch MHC.

Configuration Settings

​

The New Project wizard opens a Configuration Database Setup window to allow you to review the packages that will be used by the current project.

While the MHC tool launches, it will ask for the packages to be loaded. In the Load checkboxes list, select the csp package (by default this option is selected) and uncheck all the other packages (if any).

Click Launch to launch the MHC tool with the selected packages.
