针对蓄电池充电过程中出现的种种问题，采用了分级定电流的脉冲快速充电方案，提出了充电器的硬件电路和控制软件的设计方案。该充电方案对充分发挥蓄电池的功效，提高对蓄电池的充电速度，减少充电损耗，延长蓄电池的使用寿命具有重要意义。 -against rechargeable battery occurred in the course of various problems using the current classification set the pulse rapid charging, the charger circuitry and hardware control software design. The program rechargeable battery to give full play to the effectiveness and improve the battery charging speed, reducing wear and tear rechargeable, extended battery life is of great significance.

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
