摘要
基于USB接口的诸多优点,本文主要研究了用于A/D、D/A、开关量输入输出的USB接口系统。本文通过介绍芯片特点、硬件电路设计、软件(固件)编程、驱动程序开发过程等内容讲述了基于Cypress CY7C68013A-128AXC芯片的USB2.0接口系统设计。本接口系统还扩展了IIC总线、串口等接口,可在系统上直接连接IIC总线器件,也可以实现USB转串口的功能。
Based on the advantages of USB,this paper is to design an interface which is used for A/D,D/A,and I/O.By introduction of the CY7C68013A,hardware design ＆ software/firmware programming and the driver design,this paper proposes a design of USB2.0 interface based on Cypress CY7C68013A-128AXC.This USB interface system also includes IIC BUS and Serial BUS.So we can add IIC components to it and we can also communicate with devices which only provide serial bus interfaces.
