Hardware::iButton::Device 0.03

Hardware::iButton::Device is a Perl object to represent iButtons.

SYNOPSIS

use Hardware::iButton::Connection;
$c = new Hardware::iButton::Connection "/dev/ttyS0";
@b = $c->scan();
foreach $b (@b) {
print "id: ", $b->id(), ", reg0: ",$b->readreg(0),"n";
}

This module talks to iButtons via the "active" serial interface (anything using the DS2480, including the DS1411k and the DS 9097U). It builds up a list of devices available, lets you read and write their registers, etc.

The connection object is an Hardware::iButton::Connection. The main user-visible purpose of it is to provide a list of Hardware::iButton::Device objects. These can be subclassed once their family codes are known to provide specialized methods unique to the capabilities of that device. Those devices will then be Hardware::iButton::Device::DS1920, etc.
