# Local Digital

Warning

This driver is deprecated in favor of the Local IO (Analog and Digital) driver and will be removed in a future version of Dia.

## Overview

A Dia driver for the digital functionality present locally on the gateway on some devices. This driver presents a subset of the XBee Digital I/O driver options.

## Configuration

A typical local digital configuration block looks like this:

    - name: local_aio0
      driver: devices.xbee.xbee_devices.xbee_local_dio:XBeeLocalDIO
      settings:
        xbee_device_manager: <instance name>
        sample_rate_ms: 60000
        channel1_dir: In
        channel2_dir: Out
        channel3_dir: In
        channel4_dir: Out
        channel4_source: dio0.channel1_value

### Settings

xbee_device_manager (required)
  The name of an XBeeDeviceManager instance to manage this device.
sample_rate_ms (required)
  The sample rate of the XBee adapter in milliseconds.
channel(1-4)_dir (required)

  Operating I/O mode for appropriate pin of the adapter.

  Must be a string value comprised of one of the following:

  `In`
    Pin is configured to be an input.
  `Out`
    Pin is configured to be an output.
channel(1-4)_source (optional)
  If channel<x>_dir is configured as an output, this option setting may be specified to a `device.channel` channel name. The Boolean value of this channel will specify to logic state for pin `x` on the adapter.

## Channels

channel(1-4)_input (Get, type: bool, units: bool)
  The value measured by the device. The units will depend on the configuration of the appropriate `mode` setting.
