After parsing the Handyboard mail archive, it sounds like what I need
is the SPI port. Unless someone has other advice, I'll research this
path.
At this point, my overall plans are to construct my 'Bot as follows:
1. Use the Handyboard for motor control, "senses", and basic/instinctive
reflexes. I may also distribute some of the processing work to
(PIC or BStamp) coprocessors. It looks like the SPI port is the best
mechanism for networking the Handyboard and coprocessors together.
2. I would like to reserve a communications channel (for example, the
RS232 port) for interfacing the Handyboard with a Pentium SBC (or
a desktop PC via radio modem). The Pentium will handle the Bot's
higher cognitive functions and maintain a long term memory.
Since my expertise is in the area of software development, I still
have much to learn on the hardware/electronics side. I'm attracted
to the Handyboard because it is very well documented and has a good
support channel (this distribution and the Handyboard page).
Does anyone see any major obstacles with the above plan?
Comments?
