摘要
通用串行总线是目前最常用的一种计算机总线.文中提出了一种高速USB接口芯片(EZUSB-FX2)实现数据通信的方法,该方法基于CY7C68013芯片的特点,利用其丰富的开发指令和灵活的程序设计来实现.介绍了接口硬件结构和软件设计,并给出了具体的设计方法和步骤.实验表明,该方法具有结构简单、传输率高的特点,适合于工程应用.
USB is one of the most popular interfaces connecting peripheral devices to the host system. In this paper,the ASIC EZUSB-FX2 is used to implement the high speed serial communication. According to the characteristics of CY7C68013, this method makes use of its abundant instruction and vivid programmer to realize. This paper discusses the structure of hardware and software in detail and introduces the design method and the concrete steps of realization. Practices prove that this method is more fit for the engineering applications for its simple process and high speed.
