    ![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 string
    • options.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 A
    • state.PIOB a flag to enable the output latch state of pin B
    {
      PIOA: {pin: true, latch: true},
      PIOB: {pin: false, latch: false}
    }
