US 2003/0197677 A1 · Keyboard/mouse/GPIO interface of a wireless interface device

Abstract

A wireless interface device services communications between a wirelessly enabled host and at least one user input device. The wireless interface device includes a wireless interface unit, a processing unit, an input/output unit, and may include a power management unit. The wireless interface unit wirelessly interfaces with the wirelessly enabled host using a communication interface protocol. The input/output unit includes a keyboard interface module, a pointing device interface module, a General Purpose Input/Output (GPIO) module, and a multiplexer. The multiplexer is configurable to couple at least two of the keyboard interface module, the pointing device interface module, and the GPIO module to the at least one user input device. In one configuration, the at least one user input device includes both a keyboard and a pointing device and the multiplexer couples the keyboard to the keyboard interface module and to the GPIO module and couples the pointing device to the pointing device interface module and to the GPIO module.
