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:\Projects\getting_started_drivers_middleware.
  • Folder: Indicates the name of the MPLAB X Project .X folder. Enter "sam_e70_xpld" to create a sam_e70_xpld.X folder.

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

  • Name: Enter the project’s logical name as "getting_started_drivers_middleware_same70_xplained". This is the name that will be shown from within the 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.

Verify that the compiler is set to XC32 (v4.30) and the Tool is set to SAM E70 Xplained (EDBG). You need to connect the tool using the DEBUG USB port on the SAME70 Xplained Evaluation Kit to your PC for this option to be visible. Also, verify the package version numbers.

​

Note: This project has been verified to work with the following package versions:
CMSIS v5.8.0, SAME70_DFP v4.10.248

You are free to try the latest packages. However, since we regularly update our tools, you may occasionally discover an issue while using the newer versions. If you suspect that to be the case, we recommend that you double-check and use the same versions that the project was tested with.
