I'm new to arduino and have veeery basic atmel knowledge.
I'm looking for a way to write a bit pattern to the outputs, for example to write 00010001 to outputs 20-27. Is there a simple way? Something like on atmel loading 00010001 into a register and then performing "out portB register#".
I've performed some searches on "output byte" but didnt find anything (or didnt understand the english ;))
