Migrating ASF SAM C21 Application to MPLAB® Harmony v3 PIC32CM MC: Step 1

< Back to Lab Start

Next Step >

Step 1.1: Verify Whether the MHC Plug-in is Installed in MPLAB® X IDE

1

Verify that MPLAB® Harmony Configurator (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 Plug-in Window to Open in Standalone Mode

1

Go to Tools > Options. You will see the Options window open.

​

Note:

  • 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.

​

Note: If 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.

​

Note: 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\pic32cm_mc_getting_started.
  • Folder: Indicates the name of the MPLABX .X folder. Enter "pic32cm_mc00_curiosity_pro" to create a pic32cm_mc00_curiosity_pro.X folder.
  • Name: Indicates the name of the project that will be shown in MPLAB X IDE. Enter "getting_started_pic32cm_mc00_curiosity_pro" 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.

5

Follow the steps below to set the project’s Configuration Settings.

  • Name: Enter the configuration name as "pic32cm_mc00_curiosity_pro".
  • Target Device: Select PIC32CM1216MC00048 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 MHC.

​

Note: 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.

6

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

​

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

1

Launch Clock Easy View by clicking on the Tools menu of the MHC window and then selecting Clock Configuration.

A new window, Clock Easy View, is opened inside MHC.

2

The Clock Easy View window will then appear on your screen.
