1. Packet sniffer enables the user to view the packets travelling within the network using the USB driver from Chipcon. I have to write my own application which captures the packet.

Intro to the BACnet Stack

BACnet is a communicationsprotocol for Building Automation and Control (BAC) networks that leverage the ASHRAE, ANSI, and ISO 16484-5standard protocol. It is currentlythe most popular protocol use in Building Automation systems (BAS).

Chipkin’s BACnet Stack (CAS BACnet Stack) is a software library that allows you to add a native BACnet interface to yourembedded devices or applications. The BACnetstack supports both BACnet server (Field device, power meter, gas detector, etc.) and BACnet client (HMI,Utilities, data loggers, etc.) services giving you the flexibility you need to succeed. The Chipkin BACnetStack supports the protocol revision 19,making it a global market leader and one of a few stacks that support's revision 19. Chipkin attendsplugfest annually and as of 2018 plugfest, our stack is one of the most up to date stacks in the market.

The BACnet Stack is a transport layer independent library, making it easy to use with any transport layersuch as MSTP, IP, Ethernet and even PTP and ARCnet. By giving you control of the transport layer you canoptimize bandwidth and performanceby exploiting the resources at your disposal such as multi-threading and multiple simultaneous connections.See the diagram below of the BACnet Stack Layers which shows what portions are provided bythe stack and what by theclient:

Benefit from our 20+ years of BACnet experience!!!

Take it from us, we have been working with BACnet for 20+ years. Our BACnet Stack Resume includes 10+ yearsof development, 25,000+ commits, 50,000+ lines of code, 2,500 unit tests, 50+ devices using the stack andamong other capabilities, 1,000,000+device installations. We know what we are are doing. On top of that, we are also part of the BACnet TestingLaboratory Working Group. Purchasing the BACnet Stack from us will save you man-years ofdevelopment when your company needs it the most. Let us handle the grunt work, BACnet Spec iscomplex and it takes months of work just to learn the details.

Chipkin’s BACnet Stack (CAS BACnet Stack) is an application layer BACnet library for embedded systems andapplication development. The stack allows applicable devices to communicate using several of the BACnetflavors and can function both asa server (Field Device, etc…) or as a client (HMI, etc…).

Because we have also built the stack to be BACnet spec compliant (we do things according to the BACnetspec.), No device that used our BACnet stack has ever failed to receive the BTL Certification (BACnet International BLT) by the BACnet Testinglaboratories. We do things the right way from the start!

To ensure our BACnet stack is well tested and compatible with industrial leaders, Chipkin attends the yearlyBACnet Plugfest to test new features and services from allof the leading manufacturers.

Furthermore, the CAS BACnet Stack is particularly well-suited to most contemporary programmingstyles as the API uses XML to transfer requests for packet building as well as for handlingback-parsed packets.

Source Code and Code Quality

Chipkin's BACnet Stack source code conforms to the C++98 standard and is built for portability to manydifferent operating systems and architectures.

Extensive unit tests have been written for our BACnet Stack in Google's C++ test framework. The source code has beentested with Valgrind to detect any memoryleaks, threading issues, and performance profiling.

Drivers Chipcon Aspire

The CAS BACnet Stack is thread safe and can be used on systems that do not support threading.

Supported Architectures and Operating systems

The CAS BACnet Stack is designed for maximum portability and compatibility with as many differentarchitectures and operating systems as possible.

The CAS BACnet Stack uses a series of callbacks for accessing operating systems and network functionality. Anoperating systems Interface has been created for the standard operating systems such as Windows, Linux andRTOS and can be ported toother operating systems and embedded systems. Our BACnet stack can be considered network layer and operatingsystems independent.

As of 2019, the CAS BACnet Stack supports the protocol revision 19, making it a global market leaderand one of a few stacks that support's revision 19. Chipkin attends plugfest annually and as of 2018plugfest, our stack is one of themost up to date stacks in the market.

Operating systems Interface have been created for the following OS:

Requirements and dependency

The CAS BACnet stack is designed to have minimum requirements to maximize the portability of the source codeacross as many platforms and architectures as possible. It has the ability to run on devices with very lowresources by disabling BACnetservices to reduce the required resources and dependencies.

Minimum Requirements:

• A relative millisecond timer
• C++ compiler
• Standard Template Library (STL)
• Networking: UDP for BACnet IP or RS485 Serial for BACnet MSTP

The amount of ram that the Chipkin BACnet stack requires depends on several factors including; BACnetServices supported, Object types supported, Object count, COV limits, etc...
