"You'll be amazed when you first see a Web server running on a computer that's little bigger than a stick of chewing gum."
--From the Foreword by Tom CargillTINI (TM) (Tiny InterNet Interface) technology is the compact and powerful solution for connecting a wide variety of hardware devices directly to corporate and home networks. The TINI (TM) Specification and Developer's Guide is the complete tutorial and reference guide for developers networking embedded systems with this exciting new technology.
Written by the lead architect of the technology, this book is packed with examples and reference materials, and contains the complete TINI specification. It begins with an overview of the platform, then examines every detail of the specification from the runtime environment to device I/O, networking, and application programming. Though some Java (TM) programming language experience is a prerequisite, the book requires no embedded controller or I/O interface experience.
The key components of the TINI specification are explained, including:
The TINI platform's hardware and runtime environment
TCP/IP networking and dial-up networking using PPP
Asynchronous serial communication
TINI's parallel I/O bus, memory access modes, and port-pin control
The 1-Wire Net (TM) fundamentals, adapters, and direct 1-Wire communication
Managing system resources, including the real-time clock, the Watchdog, and external interrupts
Application programming with TINI
Programming tips for performance optimization
The accompanying CD-ROM contains code examples from the book.
Direct from the authority, The TINI (TM) Specification and Developer's Guide is the first complete reference to this innovative "anywhere anyplace" interface for Web-enabled devices.
