I recommend that you use an IOline from IO8-IO15 instead. You need to
go through some pushups to use the analog lines for digital, which
aren't worth it if you don't have to. On the other hand, with a sharp
implement you can change the pinout on your connector and plug it into
the serial LCD line on the R board.

The two controllers are different - It would be different yet for

I'm not hip to Stamp programming - are those '2' and '1' ASCII
characters or binary numbers? The answer to that question will
determine what you need to send. If they need binary numbers then what
yo have written is so, if ASCII then you need to convert to ASCII.
Other than that, you are correct.

As long as the +5V and ground are correct then you are OK.
