MPLAB harmony will re-compile the project every time. It compiles a binary that is then flashed to the device. You can update the <wolfssl-root>/wolfssl/wolfcrypt/settings.h header and re-compile to change functionality.

So, Does MPLAB harmony compile the code each time or does it use a pre-compiled library? Can I add these options as part of my Harmony project and get the project compiled with them?

There are many examples of creating new custom defines in the file

<wolfssl-root>/wolfssl/wolfcrypt/settings.h

When creating a new custom define section we place a commented out option at the top of the settings header file and note to uncomment that single define if you wish to use it.

Then we create a subsection for the define that contains all the various global configure options that pertain to operating environment.

To control features it is customary to define "WOLFSSL_USER_SETTINGS" at the project level. Then add a file named "user_settings.h" to your include path and use this header for enabling/disabling specific features. To see examples of this please have a look at the user_settings.h header files used in several of our examples:
