这是我大学同学今年的毕业设计项目：基于USB的红外鼠标。红外遥控器模拟鼠标的左右键，还有滚动条。红外接收用HS0038A接收，在这设计中红外处理部分用一块51单片机处理。USB信号处理部分（即USB设备）用51单片机和PDIUSBD12芯片构成-This is my university students graduating this year" s design project: Based on the infrared USB mouse. Infrared remote control analog left and right mouse button, as well as scroll bar. Infrared receiver with HS0038A receive, in the design of mid-infrared processing section 51 with a microcontroller processing. USB signal processing part (ie, USB devices) with 51-chip microcontroller and PDIUSBD12 composition
