Virtual Serial Port Cookbook
by Joe Pardue
This book makes USB almost easy. It uses the FTDI FT232R USBUART IC and has many instructive and useful hardware and software projects that will help the user to gain an understanding of one way to communicate between a PC and a microcontroller. The software is written in both C# and Visual Basic .NET and the components needed to do the projects will be available as kits from Smiley Micros.
