Summary:

Previous Edition: 0 7506 2228 8, published 19/06/95This book is about interfacing personal computers using C. Anyone who is interested in ports, transducer interfacing, analog to digital conversion, convolution, filters or digital/analog conversion will benefit from reading Interfacing with C. Students will also find this a practical introduction to real-time programming with a generous collection of tried and tested programs.The pace of the book is such that the reader is encouraged to run the programs and experiment with C. The principles precede the applications in most cases in
