Back to top

Find the folder where you saved the framework in the Framework Path box, and then click Next to proceed.

  • The path to your MPLAB® Harmony 3 installation folder should already be populated. If not, create a folder somewhere on your computer, like C:\harmony3, and point the project to that framework path.
  • The MPLAB Harmony 3 necessary files will be downloaded to that path later during these steps.

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:\Users\xxxx\HarmonyProjects\same51n_getting_started.
  • Folder: Indicates the name of the MPLABX .X folder. Enter "sam_e51_cnano" to create a sam_e51_cnano.X folder.

Note: This must be a valid directory name for your operating system.

  • Name: Enter the project’s logical name as "getting_started_sam_e51_cnano". This is the name that will be shown from within MPLAB X IDE.

Note: The Path box is read-only. It will update as you make changes to the other entries.

Click Next to proceed to Configuration Settings.

  • Name: Enter the configuration name as “sam_e51_cnano”.
  • Target Device: Select ATSAME51J20A 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 MCC.

Click Finish to start downloading the Required Content packages. The MCC opens the project graph once after downloading the required components.

MCC content manager select Finish

Tool Tip:

  • If you have already downloaded the required content or packages, MCC displays only the Optional Content table.
  • If your project needs additional packages or components, select the components in the Optional Content table and click Finish to download the packages.

New project wizard step 7

  • Resource Management has two sections. One is Project Resources and the other one is Device Resources.
    • Project Resources The project resources area shows all the peripherals that are already configured for the project. For example (CMSIS and Device Family Packs (DFP)). Select the peripheral here, and the peripheral is ready to be configured in the Composer area. In the Project Resource area, the System module is always present. The System module simplifies the setting of configuration bits and configures the system clock.
    • Device Resources The Device resources area displays available peripherals for the device. Click on the peripheral you want to add to your project. The peripheral moves to the MCC Project Resources area and is ready to be configured to your project's requirements. For example, MPLAB Harmony Peripheral Libraries (PLIBs) for your device.
  • Project Graph: shows the instantiated components. You can instantiate available components by double-clicking on the component in the Device Resources panel. After successful component instantiation, you can see the instantiated components under the Project Resources panel.
  • Configuration Options: Displays the tree view of the selected component under the Project Graph area. You can configure the selected optional component in this section.

Tool Tip: If you closed MCC accidentally and would like to open it again, Click on the MCC button at the top to launch the MCC.

Tool Tip: MCC, by default, has Autosave MCC configuration File option enabled. If you want to disable the MCC autosave option, go to Tools > Options. After opening the Options window, go to Plugins and disable the Autosave MCC configuration file option.
