  • 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.
