I just got a handyboard and have been playing with it.
I would like to maybe network a couple of miniboards to it for expansion using
the SPI. So:
1) how does one drive the SPI, software wise? (If this info
is in the 6811 reference manual, just tell me as I am still waiting
for mine).
2) Can I just connect the 4 SPI pins to each other (SS to SS, MISO to MISO,
MOSI to MOSI, SCLK to SCLK), or do I need to cross connect MISO and MOSI?
Are there any termination requirements, etc?
3) Can I power the miniboards from the handyboard via J13 (the power header)?
I was also thinking of of getting the Scott Edwards servo board to connect
to the Handyboard. Can anyone give me feedback on their experience doing
this?
Thanks.

| (...) It's in the 68HC11 reference manual. Not hard, but I don't think any handyboard library routines have been written to queue up bytes to be streamed out. If you write any, you might share your stuff here, I have such a need as well. (...) MISO (...) (28 years ago, 20-Sep-96, to lugnet.robotics.handyboard)
