Analog Interfacing to Embedded Microprocessors: Real World Design

Stuart Ball9780750673396, 0-7506-7339-7

Provides hard-to-find information on interfacing analog devices and technologies to the purely digital world of embedded microprocessors. Gives the reader the insight and perspective of a real embedded systems design engineer, including tips that only a hands-on professional would know. Covers important considerations for both hardware and software systmes when linking analog and digital devices.-Embedded Technology…a comprehensive source on interfacing the real world to microprocessors should prove invaluable to embedded systems engineers, students, technicians, and hobbyists. Anyone involved in connecting the analog environment to their digital machines, or troubleshooting such connections will find this book especially useful. – Embedded TechnologyIn general, for all the sections, there are plenty of simple diagrams and also the maths is kept to a simple level….I like this book and recommend it as an introduction to the subject for home use, students and SW Engineers. – Chris Hills in the ACCU magazine CVu
