Each experimental application in this book was developed and tested on the SL-AVR programming experimenter by the technical personnel of Guangzhou Tianhe Shuanglong Electronics Co., Ltd. and the teachers and students of the Department of Electronic Engineering of East China Normal University (ATMEL Laboratory). The source program list, hardware wiring diagram, and system working software can be downloaded from the Internet (http://www.s1.com.cn). Guangzhou Tianhe Shuanglong Electronics Co., Ltd. can also provide a CD with relevant working software and experimental application source programs with pictures and texts as a supplement to this book. This book has a strong systematic and practical nature. It can be used as a teaching reference for automation, computer, electronics and other majors in colleges and universities, a practical reference for engineering and technical personnel, and a training textbook for applied technology.
