Networking and Internetworking with Microcontrollers (Embedded Technology)

Sophisticated networking and communications capabilities that were previously the sole domain of mainframes, PCs, and workstations are now becoming mandatory in the realm of smaller embedded microcontrollers. However, documentation, standards, and design information is scattered among many sources and is difficult to find. In this practical book, popular columnist and embedded designer Fred Eady is your guide and advisor. He pulls together all the necessary design background and details and shows you how to use today's affordable microcontrollers for powerful communications and networking applications such as local area networks and embedded internet. Using working code examples and schematics, Eady steers you through the basics using two popular microcontroller families, PIC and Atmel. Included are a wealth of detailed design examples for: · RS-232 firmware and hardware · Cover -- Contents -- Preface -- A Quick Look at the Microcontrollers -- Chapter 1: The Essence of Microcontroller Networking-RS-232 -- Some History -- RS-232 Standard Operating Procedure -- RS-232 Voltage Conversion Considerations -- Chapter 2: Implementing RS-232 with a Microcontroller -- Basic RS-232 Hardware -- Building a Simple Microcontroller RS-232 Transceiver -- RS-232 Interface Hardware -- A Microcontroller DCE Device -- Microchip's PICkit 1 FLASH Starter Kit -- Writing Some Simple RS-232 Firmware -- A Bit of RS-232 Transmit Code -- Some RS-232 Receive Code -- Chapter 3: Writing RS-232 Microcontroller Routines in BASIC -- BASIC RS-232 -- Chapter 4: Building Some RS-232 Communications Hardware -- A Few More BASIC RS-232 Instructions -- Chapter 5: Using Microcontroller USARTs -- Some Interrupt-Driven USART Code -- Applying What We Know about RS-232 to the Atmel AVR -- Coding the AVR RS-232 Routines -- Chapter 6: I2C ...

Audience: Embedded systems engineers and programmers; electronics technicians working in embedded systems; electrical/software engineering students; electronics hobbyists.

Learn about designing, programming, and developing with the popular new Texas Instruments family of microcontrollers, the MSP430 series with this new book from Chris Nagy. This product line is experiencing explosive growth due to its low-power consumption and powerful features, but very little design and application information is available other than what is offered by the manufacturer. The book fills a gap in the technical literature for embedded systems engineers by offering a more complete combination of technical data, example code, and descriptive prose than is available from the manufacturer reference information, and is useful to both professionals and hobbyists. Intended for embedded engineers who are new to the embedded field, or for the thousands of engineers who have experience with other microcontrollers (such as PICs, 8051s, or Motorola HC0x devices) but are new to the MSP430 line, Chris Nagy offers a thorough and practical description of the device features, gives development guidelines, and provides design examples. Code examples are used in virtually every chapter and online. The book is divided into three sections: the first section provides detailed descriptions of the devices themselves; the second describes hardware/firmware development for the devices; the third is designed to incorporate information from the first two, and provide guidelines and examples of designs.

All disc-based content for this title is now available on the Web.
