Synthetic Demo Protocols

Main Repository	Generated Code	Details
cc.demo1.commsdsl	cc.demo1.generated	Demo protocol to demonstrate definition of various fields as well as simple protocol framing.
cc.demo2.commsdsl	cc.demo2.generated	Demo protocol to demonstrate protocol versioning, where every message reports protocol version in its transport frame.
cc.demo3.commsdsl	cc.demo3.generated	Demo protocol to demonstrate protocol versioning, where one “connect” message reports protocol version for all the subsequent messages.

Real Life Open Protocols

Main Repository	Generated Code	Details
cc.mqtt311.commsdsl	cc.mqtt311.generated	Defines MQTT v3.1.1 protocol, where message ID shares the same byte with extra flags, that may define existence of the fields in message payload as well as influence how message needs to be processed.
cc.mqtt5.commsdsl	cc.mqtt5.generated	Defined MQTT v5.0 protocol. Similar to v3.1.1, but also adds a heterogeneous list of various properties.
cc.mqttsn.commsdsl	cc.mqttsn.generated	Defines MQTT-SN protocol, where field of remaining length of the message can have either 1 or 3 bytes length, depending on the value it contains.
cc.ublox.commsdsl	cc.ublox.generated	Defines UBX protocol used by various u-blox GPS receivers. The protocol itself is quite complex with hundreds of messages. It uses custom checksum calculation algorithms and injects multiple code snippets to fix incorrect or incomplete functionality available by default.

Binary Data Encoding / Decoding

Main Repository	Generated Code	Details
cc.asn1.commsdsl		Provides CommsDSL schema definition to allow ASN.1 encoding.
cc.x509.commsdsl	cc.x509.generated	Provides definition of the X.509 public key infrastructure certificate.

Protocol Handling Libraries

Repository	Details
cc.mqttsn.libs	MQTT-SN client and gateway libraries.

Support for Package Managers and Other Build Systems

Repository	Details
meta-commschamp	CommsChampion Ecosystem recipes provided as a layer of the yocto project.
cc.buildroot	CommsChampion Ecosystem packages as an external customization of the main buildroot build tree.
cc.vcpkg	CommsChampion Ecosystem packages as a ports overlay directory of the vcpkg package manager.
cc.conan	CommsChampion Ecosystem packages packaging recipes for the Conan package manager.
