【摘要】 USB总线是一种新型的微机总线接口标准,而USB2.0的高速特点又是其它总线标准所无法替代的。以USB2.0总线控制器EZ-USBFX2为核心,设计了一个通用的批量数据传输模块。分析了完成批量传输的通信原理,从硬件、固件、驱动程序和应用软件4个方面阐述了该设计的方法,实现了计算机与外部设备间的传输和通信。更多还原

【Abstract】 USB is a new standard for microcomputer’s bus interface prevailing in recent years, and it is difficult to be substituted because of its high speed. The general bulk data transfer module is designed based on the USB 2.0 bus controller EZ-USB FX2 as its core. The transfer principle is analyzed and the implement method is illustrated in design of hardware, firmware, device driver, application, the transfer and communication between computers and peripheral equipment are realized.更多还原
