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

基于51单片机系统，利用AD转换芯片ADS7841，数码管驱动芯片CH452，以及CD74HC4051、CD74HC259、CD74HC154、74HC244等接口芯片实现二十路以上的电压监测、显示与通断控制。编程环境：keil-Based on 51 single-chip microcomputer system, using AD conversion chip ADS7841, digital tube driver chip CH452, and CD74HC4051, CD74HC259, CD74HC154, 74HC244 interface chip such as the way to achieve more than twenty-voltage monitoring, display and on-off control. Programming environment: keil

两篇很好的论文，论文中就已经包括(c51编写）源码。很不容易从内网上获得。-Two very good papers, papers have been included (c51 prepared) source. Easy online access from the inside.
