[ros-users] roscpp on embedded devices with ethernet?

[Dave Curtis]

Morgan,

Your initial post on the group describes the opportunity well.  Where rosserial is good for a small 8-bit microcontroller, there are a lot of 32-bit microcontrollers out there such as the Cortex-M3 and M4 processors that have ethernet controllers.  It would be really great to get those plugged into ROS as directly as possible with some kind of lightweight library that you can simply link against, without having any dependencies on sophisticated kernel infrastructure.
