Harmony is the replacement for the Microchip MLA (the original TCP/IP, USB, etc application libraries).  Currently it is only for PIC32.

It is free to use.

Advantages over the previous MPLA:

Integrated RTOS support (but does not requrie a RTOS).

Integrated 3rd party software

Run time peripheral instantiation

​Fully tested and compatible modules
