The LED on the SAM E70 Xplained Pro board is active low. Configure the LED in default OFF state by configuring the latch value to logic High.

Step 3.2: Rename the default main file

Under the Project Graph tab, click on System and give a name of your liking to the default template main file generated by the MHC.

The Configuration Options show that for a Harmony Project, MHC automatically enables generation of application files (app.c and app.h).
Change the Number of Applications to 2.
Expand Application 0 Configuration and rename the default application name to app_sensor.
