Support for Ardunino Uno

Hi, @mattions

Since the memory requirement of XRCE-DDS currently used is larger than RAM of Uno and Mega, it can not be supported.

If any vendor makes a lightweight protocol that can support DDS (if it makes it possible to run below 2K RAM), it seems to be able to support it.

Hi @OpusK,
Yeah that makes sense. I expected that the new DDS stack was a bit heavier.

I guess at the moment nobody is working on something like that

Sadly, free DDS seems to be what you said.
Some paid DDS-RPC products require a lower source than MicroXRCE-DDS, but because they require a paid license, it is difficult to use in the Arduino project.

For now, for use with UNO, Mega, like rosserial, we need to use a separate package to convert and convert to DDS format. Unfortunately, ros2arduino does not yet have a specific plan associated with it.
