基于FPGA的USB数字I/O设备设计

USB digital I/O device design based On FPGA

从系统硬件设计和软件设计2个方面阐述了USB数字I/O设备的设计方法。本次设计依据USB 2.0通信协议,以FPGA逻辑为核心控制器件,实现与USB接口芯片CY7C68013的通信控制,多通道数据的存储、读取、发送和采集。较为详细的论述了该设备的软硬件设计及实现,介绍了整体设计思路、硬件总体架构和软件流程,并且对程序进行了仿真。

This article from the hardware design and software design two aspects the USB digital I/O device design method.USB 2.0 communication protocol,according to the FPGA logic control as the core control devices,realize the USB interface chip CY7C68013 communication control,multi-channel data storage,read,send and acquisition.More detailed describes the design and realization of the software and hardware equipment,this paper programs.
