I haven't seen a HOWTO type recipe for that, but I haven't been looking.

The I/O pins in most ARM SOC chips have several uses per pin.  You have to 
get the chip specs to see what your choices are and look at the board 
schematics to see which pins are already used.

For medium speed, you might find that the BBB is already setup for SPI or 
something similar.

There are probably a couple of plain old serial ports.  You might check how 
fast they will run.
