Step 1.1: Install MPLAB® Harmony Configurator (MHC) Plugin in MPLAB X IDE
Verify that MPLAB Harmony Configurator (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, install MHC.
Step 1.2: Setup MHC Plugin Window Open in Standalone Mode
- 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
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, select Microchip Embedded. In the Projects pane, select 32-bit MPLAB Harmony 3 Project, then click Next.
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 framework downloader, see the "Download MPLAB Harmony Framework" section of the "MPLAB Harmony v3 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: C:\microchip\harmony\v3\harmony_projects.
Folder indicates the name of the MPLABX.X folder. Enter "drivers_freertos_sam_c21_xpro" to create a drivers_freertos_sam_c21_xpro.X folder.
This must be a valid directory name for your operating system.
Enter the project’s logical name as "getting_started_drivers_freertos_sam_c21_xpro". 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 other 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.
Set the project’s Configuration Settings as follows:
- Name: Enter the configuration name as "sam_c21_xpro".
- Target Device: Select ATSAMC21J18A as the target device.
You can select the Device Family or enter a partial device name to filter the Target Device list in order 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.
Before proceeding, set up the compiler toolchain. Click on the Projects tab on the top left pane. Right click on the project name getting_started_drivers_freertos_sam_c21_xpro and go to Properties.
Select Connected Hardware Tool as SAM C21 Xplained Pro. Make sure that XC32 (v2.50) is selected as the Compiler Toolchain for XC32. Click on Apply and then click on OK.
Alternative way to access the same properties tab: File > Project Properties (project name)
If you closed MHC accidently and would like to open it again, go to Tools > Embedded > MPLAB Harmony 3 Configurator.
