Intelligent Sensor Design Using the Microchip dsPIC

Intelligent seonsors are revolutionizing the world of system design in everything from sports cars to assembly lines. These new sensors have abilities that leave their predecessors in the dust! They not only measure parameters efficiently and precisely, but they also have the ability to enhance and interupt those measurements, thereby transformng raw data into truly useful information.Unlike many embedded systems books that confine themselves strictly to firmware and software, this book also delves into the supporting electronic hardware, providing the reader with a complete understanding of the issues involved when interfacing to specific types of sensor and offering insight into the real-world problems designers will face. Meaningful software examples are implemented in both C and assembly language, and the source code is included on the accompanying CD. The examples provide a complete, easily extensible code framework for sensor-based applications as well as basic support routines that are often ignored or treated superficially. The goal throughout is to make readers truly productive as quickly as possible while providing the thorough understanding necessary to design robust systems.Readers will gain in-depth, real-world design information that will help them be more productive and get up to speed on sensor design skills more quickly. The book provides designers and students a leg up in a relatively new design area, imparting knowledge about a new microcontroller that offers some of the functionality of a DSP chip.

Audience
Embedded systems engineers and programmers working onsensor design and interface in a number of markets, including automotive, aerospace, industrial controls, construction; electrical and software engineering students, electronics technicians working in embedded systems, inhouse training departments of electronicsmanufacturers

Reviews

  • "Although Huddleston specifically covers the dsPIC in this book, it is general enough to be used as an introduction on digital sensors for any DSP or DSC platform. Huddleston does get into dsPIC specifics, though he assumes a general understanding of Microchip’s DSC platform. Huddleston does cover some of the non-signal processing aspects of the dsPIC like communication support...If you plan on using the dsPIC, you’ll likely be pulling this one off the shelf for reference." - William Wong, Electronic Design
