Harmony v3 Drivers and System Services on SAM E70/S70/V70/V71: Step 1

Step 1.1: Install the MPLAB® Harmony Configurator (MHC) plug-in in the MPLAB X IDE

1

Verify that 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: 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, select Microchip Embedded. In the Projects pane, select 32-bit MPLAB Harmony 3 Project, then click Next.

If 32-bit MPLAB Harmony 3 Project is not displayed, install MHC.

3

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 Framework Downloader button, then click Next.

For more information on the framework downloader, 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: C:\microchip\harmony\v3\training\dev.
  • Folder: indicates the name of the MPLABX .X folder. Enter "drivers_sam_e70_xult" to create a drivers_sam_e70_xult.X folder.

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

  • Name: enter the project’s logical name as "getting_started_drivers_sam_e70_xult". 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 the other 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 "sam_e70_xult".
  • Target Device: Select ATSAME70Q21B as the target device.

You can select the Device Family or enter a partial device name to filter the list in Target Device in order to make it easier to locate the desired device.

  • After selecting the target device, click Finish to launch the MHC.

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