摘　　要：目前,市面上一部分轨迹球产品为单一接口,支持PS/2接口或USB接口的工作模式,且不能自动识别接口类型。文章采用Cypress公司的PSoC芯片CY7C63813-SXC,设计并实现了一种同时具备USB接口和PS/2接口,并能在相应接口下自适应工作的轨迹球。通过配套多平台主板和操作系统进行测试及环境试验发现,文章设计的轨迹球操作系统兼容性及环境适应性较好。基于CY7C63813-SXC控制器设计的自动识别USB接口和PS/2接口的轨迹球能够实现预期功能,验证了采用PSoC芯片开发计算机周边设备的可行性。At present,some trackball products adopt the single interface(either PS/2 interface or USB interface,which cannot be automatically identified).In this paper,the PSoC chip CY7C63813-SXC of Cypress Company is adopted to design and implement a kind of interface with automatic identification of USB interface and PS/2 interface.Through the testing of the supporting multi-platform motherboard and the operating system,as well as environmental verification,it is proved that the trackball designed in this paper has good operating system compatibility and environmental adaptability.It can be seen that the compatible(automatic identification)USB interface and PS/2 interface trackball based on CY7C63813-SXC controller design achieves the expected function,which validates the feasibility of using PSoC to develop computer peripherals.
