Zephyr RTOS integration

[pablogs9]

The plans of integrating Micro-XRCE-DDS inside the Zephyr RTOS can reached by two approaches:

• Adding a sample code where Micro-XRCE-DDS is retrieved as a External Project and place a demo here: https://github.com/zephyrproject-rtos/zephyr/tree/master/samples. Unfinished test are here: https://github.com/eProsima/zephyr/tree/feature/microxrcedds_sample

• Adding it as a Zephyr module. This approach require having a mirror of this repo inside Zephyr organization. An issue is required in order to request this integration. A succesful example of this procedure can be found here. The propossed text is the following:

This RFC issue is targeted towards adding Micro-XRCE-DDS library as a module to zephyr. This repository is available here: https://github.com/eProsima/Micro-XRCE-DDS-Client.

Micro XRCE-DDS is a software solution that allows communicating eXtremely Resource Constrained Environments (XRCEs) with an existing DDS network. This implementation complies with the specification proposal, “DDS for eXtremely Resource Constrained Environments” submitted to the Object Management Group (OMG) consortium. Further information here: https://micro-xrce-dds.readthedocs.io/en/latest/

One of the main purposed for this module integration is enabling Zephyr to be included in the micro-ROS project, the embedded solution of ROS 2 (https://github.com/ros2). Further information about the development of micro-ROS can be found here https://micro-ros.github.io/ and here https://github.com/micro-ROS/micro-ros-build/tree/dashing/micro_ros_setup.

Preferred repository/module name: Micro-XRCE-DDS-Client

Ping @julibert, may we put this text in a Zephyr issue for the future of https://github.com/eProsima/Micro-XRCE-DDS-Apps?
