摘要
USB2.0协议不仅支持低速(1.5Mbps)和全速(12Mbps)设备,而且支持高速设备(480Mbps),是新一代的通用串行总线标准。该文对代表业界尖端水准的USB2.0控制器EZ-USB-FX2的性能特点作了介绍,并以EP2端口数据传输为例,详细讨论了设备端固件及主机应用程序的实现方法。
USB2.0specification is a new generation of the standard peripheral interface bus.It adds high speed transfer rate of480Mbps to the12Mbps and1.5Mbps originally defined for USB.In this paper,the features of EZ-USB-FX2are introduced,which is the most advanced USB2.0Microcontroller.Moreover,the program of device firmware and host application are discussed by an example of data transfer through EP2.
