 To view the output of this project, launch MPLAB Data Visualizer from the MPLAB X IDE toolbar. In Data Visualizer, select the serial COM port associated with the PIC32CM JH00 Curiosity Nano and confirm that the settings match the configured SERCOM UART parameters in the Project Configuraiton section.

 ### Step 5: Generate MCC Code
 With UART and SysTick configured, the final step is to generate code. MCC creates the initialization files, peripheral drivers, and APIs for UART communication and SysTick timing, preparing the project for application development.

 ## Application Source Code
 <!-- Describe the main source code structure, including key functions or files, and explain how the application logic works. -->
 
 This code defines a macro for `"Hello World"`, starts the SysTick timer, and enters a loop that sends the `Hello_World` message over UART using `SERCOM1_USART_Write()`. Timing is provided by `SYSTICK_DelayMs()` to create a 500 ms delay and prevent flooding the terminal.

 ## Conclusion
 This project showed how to configure SERCOM in UART mode on a PIC32CM M0+ device using MCC Harmony. The system clock, SysTick timer, and SERCOM1 peripheral were set up to send a `"Hello World"` message every 500 ms over the Curiosity Nano’s USB CDC interface. This simple example provides a foundation for expanding into bidirectional communication or more advanced embedded applications.
