A Bluetooth Wireless Mouse System Based on Single Chip Microcomputer
Song Chen · 2008
The core protocol of Bluetooth was analyzed.With a host computer and host controller connection model,the Bluetooth module was controlled by a microcomputer through UART transport layer,thereby the HCI protocol was embedded in the microcomputer and the wireless connection could be automatically achieved.The series mouse was composed of an AT89C2051 microcomputer and the mouse codes were transferred to a computer by the Bluetooth system,thereby formed a wireless system.The Bluetooth module was Ericsson ROK101008 with low price and high reliability;the main Bluetooth chip was the C8051F023 who had 51 cores and two UART interfaces.The system is simple,cheap,and reliable.
