Step 1.1: Verify Whether the MPLAB® Harmony Configurator (MHC) Plugin is Installed in MPLAB X IDE
1
Verify that MHC is installed.
• Launch MPLAB X IDE from the Microsoft 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, install MHC.
Step 1.2: Set Up MHC Plugin Window to Open in Standalone Mode
2
- 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.
Step 1.3: Create MPLAB Harmony v3 Project Using MPLAB X IDE
1
Select File > New Project from the main IDE menu.
Close all existing opened projects before you start creating a new project.
2
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.
If the 32-bit MPLAB Harmony 3 Project is not displayed, install MHC.
3
Browse to the folder you downloaded the framework to in the Framework Path edit box. 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 "Download MPLAB Harmony Framework" section of the "MPLAB Harmony Configurator Overview" page.

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: <Your_folder>\dev\same54_low_power.
- Folder: Indicates the name of the MPLABX .X folder. Enter "sam_e54_xpro" to create a sam_e54_xpro.X folder.
- Name: Indicates the name of the project that will be shown in MPLAB X IDE. Enter "low_power_sam_e54_xpro" to set the project's name.
Note: The Path box is read-only. It will update as you make changes to the entries.
- Click Next to proceed to Configuration Settings.
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.
5
Follow the steps below to set the project’s Configuration Settings.
- Name: Enter the configuration name as "sam_e54_xpro".
- Target Device: Select ATSAME54P20A as the target device.
Note: You can select the Device Family or enter a partial device name to filter the list in Target Device to make it easier to locate the desired device.
After selecting the target device, click Finish to launch the MHC.
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.
7
Before proceeding, set up the compiler toolchain. Click on the Projects tab on the top left pane in MPLAB X IDE. Right click on the project name low_power_sam_e54_xpro and go to Properties.
Make sure that XC32 (v2.41) is selected as the Compiler Toolchain for XC32. Click on Apply and then click on OK.
Tool Tip:
If you closed MHC accidently and would like to open it again, go to Tools > Embedded > MPLAB Harmony 3 Configurator in MPLAB X IDE.
Step 1.4: Configure Clock Settings
2
The Clock Easy View window will then appear on your screen.
Tool Tip:
- The Clock Easy View window can be minimized by clicking the minimize button, as shown below.
- After minimizing the Clock Easy View window, you can see a small Clock Easy View tab at the bottom-left in MHC, as shown below.
- The Clock Easy View window can be maximized by clicking the maximize button or by double-clicking on the Clock Easy View window, as shown below.
- These tips apply to all other plugin managers like Pin Configuration, Direct Memory Access (DMA) Configuration, Event System Configuration, and Enhanced Vectored Interrupt Controller (EVIC) Configuration.
