摘要
随着通信技术的发展,通用串行总线作为一种新型接口技术得到广泛应用,它使得计算机与外部设备的连接十分方便。首先介绍USB 2.0特点,并给出了利用CY7C68013A设计控制系统的总体方案,同时对系统固件功能和驱动程序设计做了详细讨论,并提出系统设计中需要注意的一些关键性问题。控制系统固件程序采用C语言编写,上位机界面在VC++6.0环境下开发。实验表明该系统运行良好。
With the increasing development of the communication technology, the universal serial bus （USB） as a new interface technology that makes the connection of PCs with peripheral equipments very simple has been extensively adopted. The feature of USB2.0 is introduced firstly, and then the overall plan for designing the control system by using CY7C68013A is presented. The function of the system firmware and the design of drive program are discussed in detail. The key issues which should be taken more attention during the system design are proposed. The control system firmware is programmed with C language. The control interface on PC is developed under the VC^＋＋ 6.0 development environment. The experiment indicates that the whole system runs perfectly well.
