I'm thinking about a project where I multiplex some data from one Basys2 board and send it to another board to be demultiplexed and displayed.
The communication would be over one of the PMOD connector lines with three other lines used as my selection lines for an 8-bit multiplexer.
I'm wondering if there are going to be any problems regarding isolation and how the two boards would be powered. Could I power each board from its own USB connector and own PC and just go from PMOD to PMOD, or would this cause problems?
Should I write one program to ROM and then power that board from the second board through the first board's battery connector?
Would it be best to go from J5 to J5 or could a PMOD Vcc from the second board be used to power the first board?

Any other preferred methods?
thanks
