Rapid Prototyping with 32-bit MCU-based Curiosity Nano Evaluation Kit Using MPLAB Harmony v3 Software Framework: Step 1

Step 1.1: Verify Whether the MHC Plugin 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 Plugin Window to Open in Standalone Mode

1

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

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

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

Note: MPLAB Harmony v3 project creation and library code generation are now also supported under Microchip’s famous MPLAB Code Configurator tool. You could also use MPLAB Code Configurator for generating Harmony library code.

Refer:
1. Create a new MPLAB Harmony v3 project using MCC
2. Update and Configure an Existing MHC-based MPLAB Harmony v3 Project to MCC-based Project

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\pic32cmmc_smart_appliance_control.
  • Folder: Indicates the name of the MPLABX .X folder. Enter "pic32cm_mc00_cnano" to create a pic32cm_mc00_cnano.X folder.
  • Name: Indicates the name of the project that will be shown in MPLAB X IDE. Enter "smart_appliance_control_pic32cm_mc00_cnano" 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.

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

  • Name: Enter the configuration name as "pic32cm_mc00_cnano".
  • Target Device: Select PIC32CM1216MC00032 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.

Note: When configuring the compiler tool chain, make sure to select the latest PIC32CM_MC00_DFP version.

Tool Tip: If you closed MHC accidentally 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 going to 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. The default CPU clock is set to 48 MHz.
