Serin and Serout between stamps

Campeck

I want to communicate between stamps but it looks like both commands issue a clock signal. So that probably wont work right? I will need to Serout with one stamp and write my own receive code for the other stamp correct?

I don't have the code at hand, but here are some references:

on the second link, look for Master/Slave setup.

There's also a pair of Nuts and Volts Columns on networking several Stamps together. You'll have to skim through the Nuts and Volts Columns index (see the link on the Resources webpage off Parallax's main webpage). It's pretty obvious.

SERIN and SEROUT is the way to go. You might also use a 2nd I/O pin on each Stamp for signalling ("Hey there! I've got something for you!" / "OK, go ahead and send it. I'll be listening.").

Mike may referring to Columns #55 and #56 found on this page:

It's funny because I was just going through some 3-ring binders damaged in the Nashville flood from May, and those two articles where right on top, barely visible through the water streaked inkjet ink.

I took a look at those articles but they are talking about using outside hardware. I want just the two stamps.
I think I will just SEROUT on the Tx side, and make a program on the Rx side to shiftin on received clock cycles.

There is a small example in the Basic Stamp Manual starting around page 408 that maybe just what you are looking for.

Did you build those hovercrafts?

That would be off topic. PM sent.
