communicate between stamps

I do a large Christmas light display and I use some basic stamps. I
have a project coming up that will need more than 16 outputs. The
commands are simple just pin out and pause. I need to know how to get
say bs 1 to talk to bs 2 to get it to continue the commands and then
loop back to bs1 to start over again

the 74HC595. Download the StampWorks manual from Parallax to see how to use
this neat chip. With just three Stamp lines you can have 8, 16, 24 ... even
more outputs, because the '595 can be cascaded. The only thing you have to
do is keep bit patterns in memory [noparse][[/noparse]1 byte per '595] then shift them out.

second stamp and to do stamp to stamp communication. There are
simpler methods out there. E.g. use a '595 serial to parallel
converter (one to get 8 outputs, you can cascade several to get more
outputs), or apply PAK-I/O-Coprocessors
(http://www.al-williams.com/pak3.htm)

Jon just showed me how easy the 74HC595s are. I highly reccomend them, easy
to use. Let me know if you want help with code for them, Jon showed me a few
tricks. I am currently controlling 24 outputs with just 3 pins of a Stamp
and few lines of code. Very handy.
