| Abstract: | The principal of PS/2 keyboard and mouse is described, and a new design is proposed to implement a multi-keyboard and mouse system with local and remote input. And the system is controlled by single-chip microcomputer and based of transforming between RS-485 level and TTL level. Then the circuit diagram and the flow diagram are presented. The system can be used to equip a multimedia assembly room or classroom,and by contrast with other implementations, some characters such as simply setting and maintenance are (exhibited) in the system. |
