一个实用的LED条型显示屏程序，采用PHLIPS P89C51RD2芯片，LED显示驱动板为1/16分扫。本程序已经成功应用于多种场合-A practical LED bar display procedures PHLIPS P89C51RD2 chip, LED display driver board for 1/16 sweep. This procedure has been successfully applied to many occasions

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
