The book consistently examines all stages of creating embedded systems on microcontrollers using modern design technologies. Having conceived this book, the authors set themselves the task of teaching the reader the art of creating real control devices on single-chip microcontrollers. The publication contains material covering all design issues, includes many tasks for independent work, programming examples, examples of hardware solutions and experiments to study the operation of various microcontroller subsystems .This book is an excellent teaching aid for senior students of technical universities who plan to connect their professional activities with the design and implementation of embedded microprocessor systems. The book will also be useful to developers of electronic equipment based on microcontrollers.
