Embedded Linux: Hardware, Software, and Interfacing (Sams White Books)by Craig Hollabaugh
Synopses & Reviews
Embedded Linux covers the development and implementation of interfacing applications on an embedded Linux platform. It includes a comprehensive discussion of platform selection, crosscompilation, kernel compilation, root filesystem creation, booting, remote debugging, real-world interfacing, application control, data collection, archiving, and presentation.
This book includes serial, parallel, memory I/O, USB, and interrupt-driven hardware designs using x86-, StrongARM®-, and PowerPC®-based target boards. In addition, you will find simple device driver module code that connects external devices to the kernel, and network integration code that connects embedded Linux field devices to a centralized control center. Examples teach hardware developers how to store and activate field bits and deliver process information using open source software. If you are a hardware developer, software developer, system integrator, or product manager who's begun exploring embedded Linux for interfacing applications, this book is for you.
Book News Annotation:
This book covers the development and implementation of interfacing applications on an embedded Linux platform, offering a series of real- world interfacing examples designed to introduce embedded Linux from hardware and software perspectives. Readers will learn to create an embedded Linux development environment and walk through hardware and software interfacing examples using asynchronous serial communication, the PC parallel port, USB, synchronous serial communication, and interrupts. Material is presented in the context of an ongoing example. The book is of interest to hardware and software developers, system integrators, and product managers. Hollabaugh is a consultant.
Annotation c. Book News, Inc., Portland, OR (booknews.com)
A guide to using Linux on embedded platforms for interfacing to the real world. "Embedded Linux" is one of the first books available that teaches readers development and implementation of interfacing applications on an Embedded Linux platform.
About the Author
Craig Hollabaugh, Ph.D., first administered Sun® and Digital® workstations while pursuing a Ph.D. in electrical engineering at Georgia Institute of Technology. His first embedded design, US Patent #5,222,027, remotely monitors a petroleum process. In 1995, at Wireless Scientific®, he began using Linux for industrial control.
Craig currently consults for three companies from his home in Ouray, Colorado. He developed the Proteus Scalable Node™ code for Antec. At Clifton, Weiss and Associates, he's a member of a carrier-class telecommunications network design team. He's also designing FM, MP3, and Bluetooth™ headset electronics for Arriva®.
