I would posit that the easiest way is to use the serial cable. Then you
don't have to do new cabling or only work with the digital pins which
can also do output. Plus you're not spending your digital ports. You
could also go through the SPI, but I'd prefer to save that for the sonar
and such. Besides, it would also require a little cabling and some more
programming.
If you look at [1] it has some code showing how to work with the
HandyBoard from a Linux machine. The HB side is standard stuff from Fred
Martin. It is true that IC can't be running on either side while you do
this, but you don't have to move to another platform. There's a flag in
the IC OS that tells it not to listen to the serial port for commands.
Once that's set you can send whatever data you want.
I'll put up a Windows version of this stuff later in the week; I need to
package it up nicely this week anyway as we're using it this week in the
lab for our LEGO robotics class here.
