<b>C-Language Function Library for Philips LPC2100 ARM Processors - Written by Pascal Stang</b>

This is a PRE-RELEASE.
ARMlib is not complete, but is nonetheless useful in it's present form.
Be aware that libraries are likely to change as they evolve.
</b>

Procyon ARMlib \ref mainpage_footnote_one "[1]" is a library of easy-to-use
C functions for a variety of common and uncommon tasks using ARM processors.
The goal of ARMlib is to allow programmers to work quickly towards their end
goal by reducing the time needed to write basic support functions and code.
Most ARMlib header (*.h) files have lengthy descriptions of how to use the
supplied library functions. All code (*.c) files are heavily commented with
additional information.

Documentation is still being improved and refined on many libraries. When
getting familiar with a library, look first in this help document and at any
example code that is available in the avrlib/examples directory. Then look
inside the [libname].h and [libname]conf.h files, and then the [libname].c
file for more details and documentation.

Example code is included with AVRlib and can be found in the
armlib/examples directory.  The example code is organized as a set of
demo applications each of which strives to illustrate how to use a certain
ARMlib function library.  Effort is made to keep the example code heavily
(and thoughtfully) commented.

The latest version of Procyon ARMlib (including this documentation) is
available from http://hubbard.engr.scu.edu/embedded/arm/armlib

<b>[1]</b> The name "ARMlib" bears an unfortunate resemblance to "ARM libc"
even though the two libraries are different and should not be confused.
ARM libc is the Standard C Library for ARM Processors and provides functions we 
typically think of as being standard C like printf, stdio calls, math functions,
etc.  Procyon ARMlib provides additional higher-level functions designed to
help designers accomplish typical embedded systems tasks.
