BS2 serin/serout

Christopher41877

Hi,

I am using 2 bs2's and I want to connect them with one wire. Can I use serin and serout to connect them for communication? How difficult would this be?

Thanks,

Chris

It's very simple -- so easy it's in the help file (See SERIN and SEROUT).· A couple notes, though:

1) Use an open baudmode (open true with 10K pull-up·recommended) so that you can talk back and forth without fear of short circuits
2) Remember that the receiver needs to be sitting on a SERIN statment when the transmiter "talks"
··· -- you can create a simple protocol to deal with this

What I am actually trying to do is send data using the Linx LR series modules. I was using DTMF for my application but I am trying to get rid of the extra component and just use the BS2's to do this. When you refer to the help file, where exactly can I find this?

Start the Stamp Editor. You see along the top where it says Help? Click on that, and from the drop-down menu click on Contents.

And then click on "SEROUT", or "SERIN" to get to the correct entry.
