Dunno if it helps, but I messed around with multiplexing and arduino some
time ago and finally got it to work. You can check the arduino sketch and
pd patch here
This is only for reading multiplexed pins though, not for writing, but I
could use it to light LEDs one at a time sending a number from 0 to 15 to
