<h1>BACnet Stack</h1>
<h2>An open source BACnet protocol stack for embedded
systems</h2>
<hr>
<h2>About this Project</h2>
<p><a href="http://sourceforge.net/projects/bacnet/">This BACnet
protocol stack library</a> provides a BACnet application layer,
network layer and media access (MAC) layer communications
services. It is an open source, royalty-free library for an
embedded system, Windows, Linux, or other operating system.
<a href=
"https://sourceforge.net/projects/bacnet/files/bacnet-tools/">Example
BACnet client and server applications</a> are included.</p>
<p>BACnet - A Data Communication Protocol for Building Automation
and Control Networks - see <a href=
"http://www.bacnet.org/">bacnet.org</a>. BACnet is a standard
data communication protocol for Building Automation and Control
Networks. BACnet is an open protocol, which means anyone can
contribute to the standard, and anyone may use it. The only
caveat is that the BACnet standard document itself is copyrighted
by ASHRAE, and they sell the document to help defray costs of
developing and maintaining the standard (similar to IEEE or ANSI
or ISO).</p>
<p>For software developers, the BACnet protocol is a standard way
to send and receive messages on the wire containing data that is
understood by other BACnet compliant devices. The BACnet standard
defines a standard way to communicate over a number of wires,
known as Data Link/Physical Layers: Ethernet, EIA-485, EIA-232,
ARCNET, and LonTalk. The BACnet standard also defines a standard
way to communicate using UDP (IPv4 and IPv6) and TCP (HTTP for
RESTful Web Services and HTTPS for Secure Connect).</p>There are
other open source projects for BACnet:
<ul>
<li><a href=
"http://sourceforge.net/projects/yetanotherbacnetexplorer/">Yabe</a>
- Graphical explorer program for BACnet devices. Small
graphical explorer program written in C#, for browsing BACnet
devices. Currently supports both BACnet/IP, BACnet MSTP, and
BACnet PTP. Basic functions for ReadProperty, WriteProperty,
ReadPropertyMultiple, WritePropertyMultiple, I-Am, Who-Is,
SubscribeCOV, Notify, AtomicWriteFile, AtomicReadFile, and
more.</li>
<li><a href="http://vts.sourceforge.net/">VTS</a> - visual test
shell for Win32, used for Visually testing a BACnet
implementation. It also includes a detailed network sniffer for
BACnet messages, and the ability to send any BACnet services.
The source code is in the public domain.</li>
<li><a href="http://www.wireshark.org/">Wireshark</a> - an open
source, cross platform protocol analyzer with BACnet support.
The detailed BACnet support began in version 0.10.11 released
on May 4, 2005 when Wireshark was known as Ethereal.</li>

</ul>
<h2>Licensing</h2>
<p>Our BACnet protocol stack implementation is specifically
designed for the embedded BACnet appliance, using a GPL with
exception license (like <a href=
"http://ecos.sourceware.org/">eCos</a>), which means that any
changes to the core code that are distributed are made available,
but the BACnet library can be linked to proprietary code without
it becoming licensed under the GPL. See the <a href=
"http://ecos.sourceware.org/license-overview.html">eCos license
overview</a> for easy to read details about this exception to the
GPL. The license does <i>not</i> require users to release the
source code of any <i>applications</i> that are developed with
this BACnet stack - only portions of the BACnet stack that have
been modified. Note that those files in this BACnet stack that
are expected to be modified are licensed using the <a href=
"http://en.wikipedia.org/wiki/MIT_License">MIT License</a>.</p>
<p>The text of the GPL exception included in each source file is
as follows:</p>
<blockquote>
<p>"As a special exception, if other files instantiate
templates or use macros or inline functions from this file, or
you compile this file and link it with other works to produce a
work based on this file, this file does not by itself cause the
resulting work to be covered by the GNU General Public License.
However the source code for this file must still be made
available in accordance with section (3) of the GNU General
Public License."</p>
</blockquote>
<h2>The source code</h2>
<p>The source code is written in C for portability, and includes
unit tests (PC based unit tests) and example application code.
Since the code is designed to be portable, it compiles with GCC
as well as other compilers, such as Visual C++, MinGW, IAR, or
MicroChip XC. The source code is also designed to be high
quality, readable, understandable, and easy to use.</p>
<p>The BACnet protocol is an ASHRAE/ANSI/ISO standard, so this
library adheres to that standard. BACnet has no royalties or
licensing restrictions, and <a href=
"http://www.bacnet.org/VendorID/">registration for a BACnet
vendor ID</a> is free.</p>
<h2>What the code does</h2>
<p>The BACnet stack comes with example applications that can be
run under Linux, Win32, MacOS, or BSD. There are also example
projects for embedded systems and microcontrollers.</p>
<p>The unit tests use CMake and may be run with the command
sequence:</p><code>$ make test</code>
<p>The unit test framework uses a slightly modified ztest, and
the tests are located in the <code>test/</code> folder. The test
coverage tool is LCOV. The HTML results of the unit testing
coverage are available starting in the
<code>test/build/lcoverage/index.html</code> file. The unit tests
can be run on computer and run with every commit within the
Continuous Integration environment.</p>
<p>The BACnet stack was functionally tested using a variety of
tools as well as various controllers and workstations. It has
been included in many products that successfully completed BTL
testing.</p>
<h2>Demo BACnet Applications</h2>
<p>Using the Makefile in the project root directory, a dozen
sample applications are created that run under Windows or Linux.
They use the BACnet/IPv4 datalink layer for communication by
default, but could be compiled to use BACnet IPv6, Ethernet,
ARCNET, or MS/TP.</p>
<p>To build all the demo applications under Linux/Unix/Cygwin
using the BACnet/IP datalink layer, use the familiar make
command:</p><code>$ make clean all<br></code>
<p>You can also modify the Makefile variabiles from the command
line to build with the BACnet MS/TP datalink layer, for
example:</p><code>$ make BACDL_DEFINE=-DBACDL_MSTP=1 clean
all<br></code>
<p>To build all the demo applications under Windows with the
BACnet/IP datalink layer and utilizing the <a href=
"http://www.mingw.org/">MinGW tools</a> from BASH:</p><code>$
make win32<br></code>
<p>From Windows Command Line</p><code>c:\&gt; build.bat</code>
<p>The library is also instrumented to use <a href=
"https://cmake.org">CMake which can generate a project or
Makefiles for a variety of IDE or compiler. For example, to
generate a Code::Blocks project:</a></p><a href=
"https://cmake.org"><code>$ mkdir build $ cd build/ $ cmake ..
-G"CodeBlocks - Unix Makefiles" c:\&gt; mkdir build c:\&gt; cd
build/ c:\&gt; cmake .. -G"CodeBlocks - MinGW
Makefiles"</code></a>
<p>The demo application accept command line arguments. To specify
an array index of ALL, use "-1". To make a priority optional, use
"0". The applications also use environment variables to set
datalink layer preferences. Use <code>--help</code> on the
command line to see more options.</p><code>$ apps/server/bacsrv

<br></code>
<p>The demos can be compiled for Win32 platform using <a href=
"http://www.mingw.org/">MinGW - Minimalist GNU for Windows</a> or
any compiler build environment supported by CMake.</p>
<p><a href=
"https://sourceforge.net/projects/bacnet/files/bacnet-tools/">BACnet-Tools</a>
- the example applications are compiled for Windows and can be
downloaded from SourceForge.</p>
<p>To build the demo applications under Linux, such as <a href=
"http://ubuntu.com/">Ubuntu</a>, you may need to install some
build tools. There are two ways to install all the build tools
needed to compile the BACnet stack and the demo applications
using the APT package manager. The first way uses the configure
script:</p><code>$ sudo ./configure</code>
<p>The second way to install the build tools is using
bash-aptfile:</p><code>$ sudo tools/bash-aptfile/bin/aptfile
aptfile</code>
<h2>BACnet services supported matrix</h2>
<p>The BACnet stack currently implements the following services
listed in the the table. Services are added as needed for a
variety of implemetations. With the services that are
implemented, you could build a BACnet device that meets the
standardized profile for a BACnet Smart Sensor, BACnet Smart
Actuator, or a BACnet Application Specific Controller.</p>

<h2>BACnet Objects</h2>
<p>The BACnet stack currently implements an example Device
Object, and handles all of the ReadProperty and
ReadPropertyMultiple inquiries for the required Device Object
properties. The stack handles Who-Is inquiries with an I-Am,
WhoHas with I-Have, and handles reject messages for services not
currently supported or implemented by your device. There is
built-in handling for DeviceCommunicationControl.</p>
<p>The example handlers interact with example objects by way of
the Device object. There are example objects for the developer to
use as a template when customizing the objects for their
device.</p>
<p>File Objects are conditionally included in the demonstation
applications. The files can be accessed using WriteProperty,
ReadProperty, Who-Has, AtomicWriteFile, or AtomicReadFile
services.</p>

<h2>BACnet Developer Resources</h2>There are a number of
resources that can help you develop a BACnet product or project.
<ul>
<li><a href="http://vts.sourceforge.net/">VTS</a> - visual test
shell for Win32, used for Visually testing a BACnet
implementation. It also includes a detailed network sniffer for
BACnet messages, and the ability to send any BACnet services.
The source code is in the public domain.</li>
<li><a href="http://www.wireshark.org/">Wireshark</a> - an open
source, cross platform protocol analyzer with BACnet support.
The detailed BACnet support in began in version 0.10.11
released on May 4, 2005 when Wireshark was known as Ethereal.
Also, BACnet MS/TP capture support was added in Wireshark
version 1.1.0. The <a href="wireshark/index.html">demo
application mstpcap can be used to capture BACnet MS/TP using
an RS-485 converter, and save the data to a capture file that
can be viewed with Wireshark or live capture with
Wireshark.</a></li>
<li><a href="http://www.ubuntu.com/">Ubuntu Linux</a> or
<a href="http://www.debian.org/">Debian Linux</a> - my
development platforms of choice. Linux makes a great
development platform because all the necessary development
tools are included.</li>
