Description: 89S52加USBD12模拟的一个U盘（源码+原理图+实物照片）
Computer00 发表于 2006-3-3 14:09:00
USB-D12文件包下载.rar
这是一个用89S52加PDIUSBD12模拟的一个U盘，里面涉及到USB接口，USB大容量存储设备，FAT16文件系统等内容。插入电脑后，可显示移动磁盘盘符及一个文本文件。
需要说明一下的是，这个包中的原理图，IDE接口部分、74HC573、以及RS232串口等部分，是作为这个实验板的一部分。在这个模拟U盘的程序中，是没有用到的。在下一个“移动硬盘”的例子中，就用到了IDE接口跟74HC573了。至于RS232，那时笔者在调试程序时用的。如果您不需要通过串口调试程序，RS232部分可以不管它-89S52 increase USBD12 simulation of a U-Disk (OSS diagram kind photos) Comput. er00 published in 2006-3-3 14:09 : 00 USB-D12 package downloaded. rar This is a plus with 89S52 simulation PDIUSBD12 of a U disk, which relate to the USB interface, USB mass storage devices, and FAT16 file system and so forth. Insert the computer, can show that the mobile disk drive and a text file. Need to point out that this is a package of drawings, IDE interface, 74HC573. and RS232 serial port as part of the experiment as part of the plate. In this simulation U disk process is not used in the. Next a "mobile hard" cases, the option of the IDE interface with the HC573 74. For RS232, then the writer debugging procedures used. If you do not need serial debugging procedures, RS232 can be part of it reg Platform: |

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 Platform: |

Description: 简单的二级文件系统
在任一OS下，建立一个大文件，把它假象成硬盘，在其中实现一个简单的模拟文件系统。 编写一管理程序对此空间进行管理，要求：
1． 实现盘块管理
2． 实现文件的读写操作
3． 每组最多2人，小组内要有明确分工，课程设计报告中设计部分可以相同，个人实现部分不同
参考建议：
将模拟硬盘的文件空间划分为目录区，文件区；采用位示图进行空间管理，盘块的分配使用显示链接（FAT表）的方式。-Simple two file system in either OS, the establishment of a large file, the illusion of it into the hard drive, in which a simple simulation file system. The preparation of a management program space management requirements: 1. Disk block management 2. File read and write operations. Each set of up to 2, the group must be a clear division of labor, the design part of the curriculum design report can be the same individuals to achieve some of the different reference proposal: to the analog hard drive file space is divided into a directory area, file area bit diagram space management disk blocks allocated using the link (FAT table).

Description: 用类描述计算机中CPU的速度和硬盘的容量。要求Java应用程序有4个类，名字分别是PC、CPU、HardDisk和Test，其中Test是主类。
PC类与CPU和HardDisk类关联的UML图如下：
其中，CPU类要求getSpeed()返回speed的值，要求setSpeed(int m)方法将参数m的值赋值给speed。HardDisk类要求getAmount()返回amount的值，要求setAmount(int m)方法将参数m的值赋值给amount。PC类要求setCPU(CPU c)将参数c的值赋值给cpu，要求setHardDisk(HardDisk h)方法将参数h的值赋值给HD，要求show()方法能显示cpu的速度和硬盘的容量。
主类Test的要求
（1） main方法中创建一个CPU对象cpu，cpu将自己的speed设置为2200；
（2） main方法中创建一个HardDisk对象disk，disk将自己的amount设置为200；
（3） main方法中创建一个PC对象pc；
（4） pc调用setCPU(CPU c)方法，调用时实参是cpu；
（5） pc调用setHardDisk(HardDisk h)方法，调用时实参是disk
（6） pc调用show()方法。-With class describes the computer CPU speed and hard drive capacity.
