Developer Driver Tutorial

Welcome to the Developer Driver Tutorial for Niagara AX! This tutorial will walk you through the process of creating a device driver for the Niagara AX framework. Device drivers facilitate access to external equipment that is connected to a Niagara AX server through a communications or network port. This tutorial will start with a general overview of Niagara AX itself. This overview is from the author's perspective as a Niagara AX device driver developer himself. Those already familiar with Niagara AX may use the overview simply for reference. After that, this will guide you through a five-day process of Java development. It is the author's intention that you will have a fully functional, or near fully-functional driver at the end of this tutorial.
