This is the Perl script that I use
to power the live floor plan screen in ACE.
This is the Java app that runs on
the Tini that authenticates iButtons. It's very simple and there's no
documentation. The format of the text file that holds the valid iButtons
is: [iButton serial number][space][tini port to activate][newline]. The
serial number is engraved right on the iButton's can. Information about
the port numbers, as well as how to compile Java source code to run on the
Tini can be found in
.pdf on the iButton website.
