Step 7: Generate Harmony code
Resolve code generation merge conflicts.
When the Generate button is clicked, MHC will modify and generate source files based on the options selected in MPLAB® Harmony Configurator (MHC). If MHC generates code that will change a pre-existing file, it will show you the code it generated, and allow you to confirm if you want to add it to your source code.
For this lab, you should not get any merge conflicts as no custom code was added to the files that are generated or modified by the MHC.
Examine what was done after “Generating Code”.
The app folder contains files related to your specific application. In the following steps, you will add your application code to the existing app.c and app.h files. You will also add other application specific source files to the project.
The framework folder under the app folder (app/system_config/pic32mz_ef_sk_meb2/framework) contains customized Harmony Framework files. These files have been generated by MHC in response to your specific MHC selections.
Also note MHC has generated three custom graphics source files for you, based on the selections you made in the previous step. It has placed these new source files in the Source Files/app/system_config/pic32mz_ef_sk_meb2 folder.
Harmony groups all source files supporting a specific hardware platform into their own system_config folder (named pic32mz_ef_sk_meb2 in this case). Doing this enables one MPLAB X IDE project to support multiple hardware platforms by using its project configurations feature. "Project configurations" includes or excludes hardware specific configuration folders based on the target hardware you select for a specific build.
The folders under the Source Files/framework folder contain standard Harmony Framework files that have been added to your project by MHC (based on your MHC selections). To be clear, unlike the framework files found under the app folder, these files have not been modified by MHC. These are standard Harmony Framework files included in the Harmony Framework download.
Source Files/framework/decoder contains Audio Decoder library files.
Source Files/framework/driver contains Driver library files.
Source Files/framework/gfx contains Graphics library files.
Source Files/framework/system contains System Service library files
If you were to build the project now, the build would fail as you have not added the necessary application code. You will add the application code in next step.
