XBee Analog I/O Adapter

Python modules for configuring inputs and outputs

Digi provides a library of Python modules for configuring inputs and outputs

on the adapter and retrieving data from the adapter. These modules are

available for downloading from www.digi.com/din/docs, in a file named

XBee Adapter Libraries. By uploading these Python modules to the

gateway that serves as a coordinator for the adapter, you can use them in

your own programs.

Python module descriptions

The Python modules in the XBee Adapter Libraries that are relevant to

programming the XBee Analog I/O Adapter are:

Upload Python modules to gateway

1. Go to www.digi.com/din/docs.

2. In the list of downloadable files, select and download file

XBee Adapter Libraries.

3. Unzip the downloaded file.

4. Read the readme file.

5. Open the web interface for the gateway, go to Applications > Python.

6. In the Upload File edit box, enter the file name for the

XBee Adapter Libraries, DigiXBeeDrivers.zip, using the Browse

button as needed, and click Upload.

Use Python modules in programs

To use the Python modules in the XBee Adapter Libraries in programs that

you develop, append this statement:

sys.path.append("WEB/python/DigiXBeeDrivers.zip")

Module Description

xbeeprodid.py Contains calls to determine the type of adapter; (Analog,

Digital, Sensor, RS-232, etc.)

xbeedevice.py Implements a base class of any XBee device on the ZigBee

network.

xbeeain.py Configures analog mode, issues AT commands to retrieve

data from the adapter, including raw analog sample data

and sensor data scaled appropriately for operating mode,

and toggles power on/off on terminal 6. Functions and

arguments are shown on page 25.

This module derives an AIO (analog input/output) class from

the base class of any XBee device on the ZigBee network.

That is, module xbeeain.py uses xbeedevice.py internally.

sensor_io.py Decodes the output of the AT IS command.
