Ok I've had another read of the FAQ, as well as a close look at the
schematics for the handyboard and the expansion board. Correct me if I'm
wrong, but I think I can use d0-d7 along with Y0 or similar and hook these
into a HC374 to get some digital outputs.
My question is, what address do I have to poke to in order to set or unset
these bits? I can't find this information anywhere, and I've gone over all
the source code I can find. Also what should the sequence be? I know it's
similar to the motor output routines, but I can't work it out.
Any help would be great,
Thanks
Adam

| it's in the faq, at (URL) you do is write to 0x4000, 0x5000, 0x6000 depending on whether your latch is attached to Y0, Y2, or Y4 (respectively). e.g., "poke(0x4000, 0xff);" will set all the bits of a latch attached to Y0 to 1.
