MPLAB® Harmony v3 Drivers on SAM C21 MCUs Using FreeRTOS™: Step 4

By default, the Autosave MPLAB^® Code Configuration (MCC) configuration file option is enabled. That means MCC automatically saves your MCC configurations.

Now, generate the code by using MCC. From the left side tab, Resource Management (MCC), go to Project Resources and click on the Generate button.

Examine the generated code. 

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

In the generated code, notice the Peripheral Library (PLIB) files generated for SERCOM2 as I²C, Universal Synchronous Asynchronous Receiver Transmitter (SERCOM4 as USART), and PORT peripherals. Also, notice the generated files for USART, I²C Drivers synchronous drivers, and the necessary files for selected RTOS (FreeRTOS™).

MCC also generates the template main file (main_c21.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.

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.
