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.
The dsPIC30F Peripheral Library supports the
following hardware peripheral modules:
? Timers
Features
? For each individual device from the dsPIC30F family,
there is a file that includes functions corresponding to
peripherals present in that particular device.
? ‘C’ include files enable the user to take advantage of
predefined constants for passing parameters to
various library functions. There is an include file for
each peripheral module.
? Since the functions are in the form of precompiled
libraries, they may be called from a user application
program written in either MPLAB ? C30 or dsPIC30F

? ‘C’ source code is also included so users can
customize the functions to suit specific application
requirements.
? Predefined constants in ‘C’ include files eliminate the
need to refer to details and structure of Special
Function Registers, while initializing peripherals or
checking status bits.
Resource Requirements
Program Memory
The Peripheral Library functions have been optimized
for reduced program memory usage. Since the
Functions for controlling an external LCD through
configurable I/O port pins are also provided
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.
