Generate Code

Click on the Resource Management [MCC] tab on the top left pane. Click the Generate button in the Project Resources.

Click on the generate code button


As the code is generated, MPLAB® Code Configurator (MCC) displays the progress.

MCC will include all the MPLAB Harmony library files and generate the code based on the MCC selections. The generated code will add files and folders to your MPLAB Harmony project as shown.

Among the generated code, notice the Peripheral Library (PLIB) files generated for the Two-Wire Interface (SERCOM2 as I²C), Universal Synchronous Asynchronous Receiver Transmitter (SERCOM3 as USART), and PORT peripherals. Also, notice the generated files for the USART, I²C Drivers synchronous drivers, and the necessary files for selected RTOS (FreeRTOS).

MCC also generates the template main file (main_d21.c), the application thread files (app_eeprom_thread.c, app_sensor_thread.c and app_user_input_thread.c) for the EEPROM, sensor, and user input threads.


Navigate to the Projects tab to view the project tree structure.

Build the code by clicking on the Clean and Build button and verify that the project builds successfully. At this point, you are ready to start implementing your application code.
