Configure Pins for Switch and LED

Configure switch button pin with General Purpose Input/Output (GPIO) interrupt handler

The switch button will be configured as per the design schematic of the Curiosity PIC32MZ EF 2.0 Development Board shown below.

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.
