Announcing ROS2 support for the Renesas embedded MCU RX63N - software release

Renesas are pleased to announce the release of a ROS2 implementation for lightweight MCU, the RX63N.

[https://github.com/godzilla-max/freertps](https://github.com/godzilla-max/freertps)

This software makes it possible to run ROS2 on a Renesas RX63N microcontroller. The software was presented at ROSCon2017 as a lightning talk ([slides](https://roscon.ros.org/2017/presentations/ROSCon%202017%20Lightning%20110.pdf), [video](https://vimeo.com/236129109#t=24m18s); skip to 24:18). It integrates FreeRTPS and runs in a tiny memory space (ROM: 69.2KB, RAM: 51.9KB) even with a joystick/pan-tilt unit control application. It can also talk to ROS2 running on a PC (with the PC running FastRTPS) and still have enough headroom for other embedded applications to run.

This project contains both RTPS code which was forked from the original [freertps](https://github.com/ros2/freertps) and the code for the target MCU. Setup and demo instructions are available at the [project’s GitHub repository page](https://github.com/godzilla-max/freertps) that show how easy it is to use ROS2 on a lightweight MCU.
