Introduction

This document is for developers using the OpenHome SDK to integrate a Widget into an OpenHome system. Each Widget must have its own driver to allow it to communicate with the OpenHome Nodes.

To help you write your driver, this document provides high level descriptions of the core responsibilities of a Widget driver and gives a detailed walk-through using example code.

Full versions of each file used in the development of the example driver are available in the Appendix.

Prerequisites

To begin development of your Widget driver you must be in possession of the following items:

your Widget Service XML that describes the properties on your Widget.

Note

This document does not contain advice on how to write Widget Service XML. Refer to the OpenHome Widget Service XML definition document for more details.

the OpenHome SDK
your chosen communication protocol's API

The protocol you choose for your Widgets must be the same protocol used on your choice of Node.

Note

This document focuses on the development of the Widget driver. Details about the communications protocol used are beyond the scope of this document. This document assumes you are familiar with your chosen protocol's code libraries and are able to use them in the driver code you write.
