I'm a teaching assistant for a course at brown university that uses legOS
and the RCX extensively. I've added quite a bit to legOS (0.2.5) to suit
our course needs, but the rest is all still there. I've written up some
documentation and an API for legOS, including LNP. You can reach the
documentation from here:
http://www.cs.brown.edu/courses/cs148
For the course, we added another layer to LNP - a simple reliable messaging
layer based on a stop-and-wait protocol with a single parity bit for the
sequence number. You'll probably want to ignore anything that refers to
"reliable", cause that's not part of the official legOS distro. There are
also a couple functions for runtime changing of the brick's LNP address
[lnp_get_hostaddr(), lnp_set_hostaddr()] that you'll want to ignore cause
those aren't there either.
hope that helps,
-Albert
ps: Once exams are over and school gets out, I'll see if I can clean up the
changes I made and see if anyone wants patches.
