dsPIC30F Peripheral Library
The dsPIC30F Peripheral Library provides a set of
functions for setting up and controlling the operation of
all the peripheral modules available in the dsPIC30F
devices, as well as functions for interfacing with an
external LCD. The Peripheral Library serves as a
convenient layer of abstraction over the specific details
of the peripherals and their associated control and
status registers.

Resource Requirements
Program Memory
The Peripheral Library functions have been optimized
for reduced program memory usage. Since the
functions are in the form of libraries, the actual program
memory requirements depend on the functions being
called by the application, as well as on the specific
dsPIC30F device being used.

Data Memory
The vast majority of the functions do not use RAM at
all. Each of the remaining functions uses less than
10 bytes of RAM.
