Step 1: Rename Project
Since you are working on Lab 4, you are going to rename the existing project and overwrite the code from the previous lab.
To rename the project, right-click on your project name on MPLAB X IDE and select Rename. Then, change the name to pic32_wfi32e_lab4, tick the box Also Rename Project Folder, and press Rename.
Note: If required, you can make a copy of the existing project.
Note: If required, you can start from the solution of the previous Lab located in the folder: <your unzipped folder path>\getting_started_pic32_wfi32e\Lab3\solution.
