基于USB接口的计算机外围控制系统设计研究

Peripheral Control System Design of Computer Based on USB Interface

随着计算机外设的增多,通用串行总线作为一种新型接口技术得到广泛应用,它不但解决了设备对传输速率的需求,而且简化了计算机与外部设备的连接过程。给出了利用CY7C68013A芯片设计控制系统的模式选择,同时对系统固件功能和驱动程序设计作了详细讨论,并提出了系统设计中需要注意的一些关键问题。系统固件程序在KeilC51开发环境下采用C语言编写,并在VisualC#环境下完成上位机程序开发。

With the increasingly number of computer peripheral,the universal serial bus as a new interface technology has been extensively applied.This technology not only meets the data transmission need between the peripheral and PC,but also makes the connection very simple.This paper presents how to select the mode of the control system by using CY7C68013A,and discusses the function of the system firmware and the design of driver in detail.The key questions proposed are very important to the USB system design.Finally,the control system firmware is programmed with the C language using the Keil C51 software,and the control interface run on the PC is developed under the Visual C# development environment.
