Stamp Communication Method...?

Posts: 46,084
Hi all! I'm looking for a method that would allow 4 Stamps to communicate
with each-other. Because the Stamps will be occupied with other devices, I do
not want to rely solely on a software method. Ideally, each stamp would send
out the data with a suffix, identifying the intended receiver... But, since
the receiver of the data will most likely be busy with "those other devices,"
it will not receive the data. So, I want to send the data to a "blackboard"
that each Stamp can read, to see if there is any data waiting for it, and
then retrieve it. (Just to make it clear, each Stamp should also be able to
write to it.) I want to do this with a maximum of 3 I/O lines per Stamp. Any
ideas? Devices? Source code? Has anyone already done this?
Thanks in Advance,
