Publisher's Synopsis
Linux is becoming the OS of choice for embedded system designers and engineers, due to its real-time power and flexibility. Written for Engineers and students, practical Linux programming: device drives, embedded systems, and the Internet is about designing and developing embedded systems, using Internet technology as a user interface. The book emphasises the use of three different technologies for embedded system design and development: The web, the Linux kernel, and SQL queries. From a software design point of view, device driver design, Interprocess communication usage, Perl programming, shell programming, HTML tags, and SQL queries are covered in detail. The examples demonstrate the guidelines for designing an embedded system that requires interaction of different software modules and show how an operating system like Linux helps glue your software modules together. The book is presented as a tutorial for students and engineers who wish to learn the process of designing an embedded system application using Linux as the real-time operating system and the Internet as the user interface.Key features* teaches how to create a virtual web hosting system to use as the user interface for embedded systems, complete with the DNS server, SQL Server and the HTTP server setup* explains how to design device drivers to form the backbone of the embedded system's external hardware interface* provides real-world tutorials for embedded projects, including network printers, data acquisition systems, entrance security, and other General applications* show how to modularize a design project into manageable objects to achieve a fast and efficient product development cycle.* Covers the Interprocess communication facilities of the Linux kernel, including the semaphores, shared memories, and message queues used to interconnect and link software modules.
