Main files for digital PFC

This firmware is structured in such a way as to allow easy integration with other existing
applications.
The software for the digital PFC is composed of two files. The first, "PFC.c", contains all the
functions, while the second, "PFC.h", contains the definitions of the system parameters
(other than constants used internally by the main file).
Obviously, with an existing (host) application, some additional steps must be accomplished
to integrate the PFC software. Assuming that the host application has the minimum
necessary resources available (in terms of embedded peripherals, CPU load and code
memory), it is basically sufficient to include these two files in the host application firmware
and to appropriately call a function that initializes and starts the digital PFC.
