Welcome
Echelon's FTXL products enable any product that contains an Altera Nios II processor to quickly and inexpensively become a networked smart device. An FTXL device includes a complete ANSI/CEA 709.1-B (EN14908.1) implementation that runs on the Nios II embedded processor. Thus, the FTXL 3190 Free Topology Smart Transceiver Chip provides a simple way to add LONWORKS networking to smart devices. The FTXL Transceiver is easy to use because it has a simple host application programming interface (API), a pre-built link-layer driver, a simple hardware interface, and comprehensive tool support. This document describes how to develop an application for a LONWORKS device using Echelon's FTXL Transceiver. It describes the architecture of an FTXL device and how to develop the software for an FTXL device. Development of a FTXL device includes creating a model file, running the LonTalk Interface Developer utility, and using the FTXL API functions to program your FTXL application for the Nios II processor. See the FTXL Hardware Guide for a description of the hardware interfaces for an FTXL device, the development boards for which the FTXL Developer's Kit provides reference designs, and FPGA design requirements for an FTXL device.
