This appendix provides an overview of the serial data transmission techniques you may need to understand when creating an in-depth design and implementing your AVR projects. This is by no means an exhaustive survey of the subject, which is huge, but it should give you the information that you need in understanding the serial data communication methods used in this book’s projects.

Data communication over long distances has always had to be a serial process, but at one time it looked like serial transmission would be consigned to history for very short distance transfer purposes. However, as machines got faster ...
