摘　　要：为解决单一轨迹球不能自动识别何种工作模式问题,文中采用CYPRESS半导体公司的CY7C63833控制器芯片和AVAGO公司的ADNS-5020EN光学传感器,设计并实现一种高性能的双模光电轨迹球,该轨迹球可在PS/2模式和USB模式下自适应工作。设计使用的CY7C63833控制器芯片整合了USB SIE、通用I/O口以及en Co Re内核,满足了轨迹球开发在价格和性能上的要求,采用它能快速设计出低成本、高性能的人机接口设备。经实际使用测试,该设计具备有线鼠标的全部功能,同时数据传输稳定,轨迹球移动灵活,无停滞现象,在实际项目中得到了很好的应用。In order to solve the problem that the single trackball cannot automatically recognize the working mode problem, a CY7 C63833 controller chip from CYPRESS Semiconductor and an ADNS-5020 EN optical sensor fromAVAGO are used to design and implement a high-performance dual mode photoelectric trackball. The ball can workadaptively in PS/2 mode and USB mode. The CY7 C63833 controller chip used in the design integrates the USB SIE,general-purpose I/O ports, and en Co Re core to meet the price and performance requirements of trackball development.It can quickly design a low-cost, high-performance human interface device. The actual use of the test, the design hasall the features of a wired mouse, while data transmission is stable. The trackball moves flexibly, no stagnation phenomenon. It has been well applied in the actual projects.
