TOS is an 'operating system' for micro-controllers which makes
many programming tasks easier. It supplies functionality that
might speed developemnt of sensor based projects because a lot
of the 'extra' stuff, timers and such, are already implemented.
If you don't already have hardware for your controller, it's
worth looking at the Motes.
That said, there is a learning cliff to using TOS that may not
be equivalent to doing a one-off MASM implementation on a PIC.
And porting TOS to your hardware is probably more trouble than
it's worth unless you have a lot of projects to do.
ps...how do you get the cool greek characters on your message?
it doesn't seem to hold up through replies from the US...
