The mouse is one of the best proven, widely used and inexpensive man-machine interfaces ever devised, yet its presence in the world of embedded systems is still a rarity. Indeed, there are few embedded engineers today having practical experience of how to implement the hardware and software required to "enable" mouse input.

In Mouse Interfacing with USB and PS/2, the concepts needed are thoroughly explained. The practical development which stems from this knowledge is soon explored, with the feedback from each step providing impetus for the next.

This book describes in-depth how to connect the mouse into new embedded applications. It details the two main interface methods, PS/2 and USB, and offers applications guidance with hardware and software examples plus tips on interfacing the mouse to typical microcontrollers.

A wide range of topics is explored, including

• Ballistic profiles for fast-yet-precise response
• A four-channel, millivolt-precision voltage reference
• USB descriptors
• A variety of examples all with fully documented source-code

If you need to interface an embedded system to a mouse (PS/2 or USB), then this book will prove an invaluble tool. A wealth of clear illustrations enhance this highly readable text.
