Hah ok will tell Paul to spell right. Is Ros serial using sockets for small embedded linux processors. It was implemented on the Vex Pro and Chumby in our testing. <br><br><div class="gmail_quote">On Wed, Sep 12, 2012 at 2:58 PM, Dave Curtis <span dir="ltr"><<a href="mailto:dave@dave-curtis.com" target="_blank">dave@dave-curtis.com</a>></span> wrote:<br>

But it does say "imbedded Linux", which is still considerably different from an MMU-less uCtlr. So, is rosserial_embeddedlinux more light weight than its name would imply?<br>

> Suppose you have an embedded device that has an ethernet controller and enough oomph to run a TCP stack and an RTOS, for instance an ARM Cortex-M3. Is it possible to run roscpp on the bare metal, or does roscpp depend on a lot of Linux system services? Of course, rosserial would be an option, but if you have an ethernet controller on chip, that seems limiting. Or is there another light-weight ROS comms on TCP that I don't know about?<br>
