基于EZ-USB FX2LP的高速数据传输系统设计

Design for Streaming High-speed Data Based on EZ-USB FX2LP

设计了一种基于EZ-USBFX2LP的USB2.0高速数据流传输系统。给出了完整的软硬件设计方案,包括硬件电路设计调试、编写固件程序、驱动程序、应用程序。对其中的关键性问题做了分析归纳。最后,给出了高速模式下块传输和同步传输的测试数据。实践证明,此设计稳定可靠,具有良好的移植性,在高速数据传输系统中具有广泛的应用价值。

A high-speed streaming data system based on EZ-USB FX2LP was designed. Design proposal including hardware and soft-ware is presented,including hardware circuit,firmware of MCU,driver and application programs of host. The solution to some crucial questions is analyzed. At last,A test report about bulk transfer and isochronous transfer in high-speed mode is given. The practice shows that this design works stably and reliably. With good portability,it will have a wide application in high-speed data transmis-si...
