# DS2413 Onewire IO Module
[](https://gitter.im/ianmetcalf/node-ds2482?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
Provides an interface for Dallas DS2413 IO modules over the DS2482 onewire bridge
# Install
```
$ npm install ds2482-io
```
# Usage
```js
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](https://github.com/ianmetcalf/node-ds2482)
### new DS2413.Module(rom [, options])
Creates an io module instance
- `rom` the ROM address of the module as a 16 character hex encoded string
- `options.wire` an instance of [wire](https://github.com/ianmetcalf/node-ds2482)
### 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
```js
[
]
```
### module.read(callback)
Reads the current pin and latch state status of the module
```js
{
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 A
- `state.PIOB` a flag to enable the output latch state of pin B
```js
{
PIOA: {pin: true, latch: true},
PIOB: {pin: false, latch: false}
}
```
