also, mcp23018_init() needs fixing: `twi_stop()` needs to be at the end of transmission blocks. i wouldn't think that would be necessary, but it seems to be the only thing that'll make it work, and it also seems consistent with the protocol diagram in the datasheet (lol, imagine that), so i think that's what i'll have to do. not as though it matters much i guess, since it's a single master / single slave system anyway, i was just hoping not to release the bus till i was finished..
