README
DS2413 Onewire IO Module
![Gitter](https://badges.gitter.im/Join Chat.svg)
Provides an interface for Dallas DS2413 IO modules over the DS2482 onewire bridge
Install
$ npm install ds2482-io
Usage
var DS2413 = require('ds2482-io');
var io = new DS2413();
io.init(function(err) {
if (err) { throw err; }
io.search(function(err, modules) {
if (err) { throw err; }
modules.forEach(function(module) {
module.write({PIOA: true}, function(err, resp) {
if (err) { throw err; }
console.log(resp); // Returns the status of each module
});
});
});
});
API
new DS2413([options])
Creates an interface for Dallas DS2413 IO modules
options.wire
an instance of wire
new DS2413.Module(rom [, options])
Creates an io module instance
rom
the ROM address of the module as a 16 character hex encoded stringoptions.wire
an instance of wire
io.init(callback)
Resets the bridge chip and any onewire devices connected to it
io.search(callback)
Searches the bus and returns a list of found io modules
[
<Module "3ae9f412000000a6">
]
module.read(callback)
Reads the current pin and latch state status of the module
{
PIOA: {pin: false, latch: false},
PIOB: {pin: false, latch: false}
}
module.write(state, callback)
Writes the latch state to the module and returns the current status
state.PIOA
a flag to enable the output latch state of pin Astate.PIOB
a flag to enable the output latch state of pin B
{
PIOA: {pin: true, latch: true},
PIOB: {pin: false, latch: false}
}
