Description: 设备驱动可以理解为操作系统的一部分，对于一个特定的硬件设备来说，其对应的设备驱动是不同的。本系统要使用摄像头获取视频数据，所以编写摄像头驱动是必需得。我们选用的是OV公司系列摄像头，因为对于嵌入式开发，几乎没有通用的驱动程序可以用，不同的软硬件环境有其特殊性。本文档阐述的摄像头驱动是基于OMAP芯片和嵌入式Linux系统的。-device driver can be understood as part of the operating system for a specific hardware device, its counterpart device drivers are different. The use of the system to access video camera data, the preparation of camera is essential in driving. Our choices are the OV companies series camera, because for embedded development, almost no common driver can use different hardware and software environments are unique. This document set out the camera driver is based on the OMAP chips and embedded Linux system.

Description: 摄像头的工作原理大致为：景物通过镜头（LENS）生成的光学图像投射到图像传感器表面上，然后转为电信号，经过A/D（模数转换）转换后变为数字图像信号，再送到数字信号处理芯片（DSP）中加工处理，再通过USB接口传输到电脑中处理，通过显示器就可以看到图像了。 -The working principle of the camera more or less as follows: the scene through the lens (LENS) to generate the optical image projected onto the image sensor surface, and then converted to electrical signals, after A/D (analog-digital conversion) converted into a digital image signal, and then sent to digital signal processing chip (DSP) in the processing, transmission through the USB interface to computer processing, through the display can be seen on the images.

Description: 利用89S52为核心实现的IDE-USB转接器
现在已经实现了主要功能：可以读取文件和复制文件。不支持格式化硬盘功能。
不过速度比较慢，我从本地硬盘复制文件到移动硬盘里去，速度只有50KBytes/S，
因为单片机速度不快，内存又少，USB1.1的速度也不快。另外，代码写得不够好
压缩包内有线路图-89S52 realize use as the core of the IDE-USB adapter now realize the main function: You can read the files and copy files. Reformat your hard disk does not support the function. More slowly, however, I copy files from the local hard disk to a mobile hard drive into a speed only 50KBytes/S, because of slow single-chip, memory less, USB1.1 speed is not fast. In addition, the code written is not good enough compression packages have circuit diagram
