Developers who want to access USB devices from their embedded systems will find a helpful resource in USB Embedded Hosts: The Developer’s Guide. This new book from the author of USB Complete shows how small systems can take advantage of the same wealth of USB devices available to conventional PCs. The book begins with a review of USB host communication protocols. Readers then learn which USB host requirements are relaxed for embedded systems and what new requirements some embedded systems must meet. To help in selecting a development platform, the book explores available hardware and software for USB host communications in small systems. The heart of the book focuses on communicating with USB devices. The topics (with example code) include USB drives, keyboards, virtual serial ports, network bridges, mics, speakers, video cameras, and printers, plus devices that don’t fit defined USB classes. Also discussed are systems that support both USB host and device functions. The example code is written for the BeagleBoard-xM open development board using a distribution of Linux targeted to small systems. Also covered is how to use Linux commands and utilities to learn about, monitor, and debug communications with USB devices.

This developer's guide for designers and programmers of mass-storage devices that use the Universal Serial Bus (USB) interface provides developers with information on how to choose storage media, interface the media to a microcontroller or other CPU, and write device firmware to access the media and perform USB communications. Comparisons of popular storage-media options to help users choose a media type for a project are included, and the types described cover hard drives and flash-memory cards such as the MultiMediaCard (MMC), Secure Digital (SD) card, and CompactFlash card. Helpful tips on developing an embedded host that can access USB mass-storage devices are also covered.

This unique guide goes beyond all the USB specification overviews to provide designers with the expert knowledge and skills they need to design and implement USB I/O devices.

This guide takes the pain out of designing for this popular interface with specific, detailed examples that show how to develop USB devices and the applications that communicate with them. How the USB communicates with the PC, deciding if a project should use a USB interface, choosing a USB controller chip for peripheral design, and determining code with Windows applications are covered in detail.

Computing: general.

8115C-5.TXT The complete guide to the revolutionary new USB standard. Written for everyone-from users to engineers. Operating system support and troubleshooting techniques.

USB devices are coming fast, and built-in USB support is a key feature of Windows 98. Now there's a complete guide to making the most of this hot new connectivity standard: Universal Serial Bus Explained. Co-authored by the best-selling author of RS-232 Made Easy, this book is written in layman's terms for every interested computer user-and it's comprehensive enough to serve the needs of hardware and software developers. You'll find thorough coverage of: Setting up USB hardware and interfacing peripherals. USB protocols and data flow: what actually happens “on the wire.” A close look inside USB hubs, bus interconnects, devices, and hosts. Troubleshooting USB: Analyzing bus traffic and device configuration. USB support in Windows and other operating systems. Universal Serial Bus Explained shows how the USB standard delivers easy peripheral expansion, fast data transfer, guaranteed bandwidth for multimedia, low cost, true “plug-and-play” support, and a whole lot more. It answers today's most frequently asked questions about USB and the new generation of devices that utilize it. Detailed appendices provide more information about the USB specification; Internet-based resources, periodicals and technical conferences; and an extensive source list for USB devices and software. Whether you want to use USB devices or invent them, this is the only USB book you'll ever need.

For the first time in a single reference, this book provides the beginner with a coherent and logical introduction to the hardware and software of the PIC32, bringing together key material from the PIC32 Reference Manual, Data Sheets, XC32 C Compiler User's Guide, Assembler and Linker Guide, MIPS32 CPU manuals, and Harmony documentation. This book also trains you to use the Microchip documentation, allowing better life-long learning of the PIC32. The philosophy is to get you started quickly, but to emphasize fundamentals and to eliminate "magic steps" that prevent a deep understanding of how the software you write connects to the hardware. Applications focus on mechatronics: microcontroller-controlled electromechanical systems incorporating sensors and actuators. To support a learn-by-doing approach, you can follow the examples throughout the book using the sample code and your PIC32 development board. The exercises at the end of each chapter help you put your new skills to practice. Coverage includes: A practical introduction to the C programming language Getting up and running quickly with the PIC32 An exploration of the hardware architecture of the PIC32 and differences among PIC32 families Fundamentals of embedded computing with the PIC32, including the build process, time- and memory-efficient programming, and interrupts A peripheral reference, with extensive sample code covering digital input and output, counter/timers, PWM, analog input, input capture, watchdog timer, and communication by the parallel master port, SPI, I2C, CAN, USB, and UART An introduction to the Microchip Harmony programming framework Essential topics in mechatronics, including interfacing sensors to the PIC32, digital signal processing, theory of operation and control of brushed DC motors, motor sizing and gearing, and other actuators such as stepper motors, RC servos, and brushless DC motors For more information on the book, and to download free sample code, please visit http://www.nu32.org Extensive, freely downloadable sample code for the NU32 development board incorporating the PIC32MX795F512H microcontroller Free online instructional videos to support many of the chapters
