Probably not, depending on how your write your code. The Master will
send data on the MOSI pin, and the slave will receive on the MOSI
pin, so that would be straight through cable.
Depends though, if all your boards are masters, then you must cross
connect. Typically though, the design of the SPI subsystem should
work with one master, and other slaves.

| (...) 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 (...) (29 years ago, 20-Sep-96, to lugnet.robotics.handyboard)
