As the code is generated, MHC displays the progress as shown in the accompanying image.

Generating Progress window

Navigate to the Projects tab in MPLAB X IDE to view the project tree structure.

Examine the generated code as shown in the accompanying image.

Projects tab

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

Among the generated code, notice the Peripheral Library (PLIB) files generated for Real-Time Clock (RTC), SERCOM 2 (as I²C), SERCOM 3 (as Universal Synchronous Asynchronous Receiver Transmitter (USART)), Direct Memory Access (DMA), External Interrupt Controller (EIC), and PORT peripherals. MHC also generates the template main file (main_d21.c).

Build the project

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