keil c51在编译的时候会将0xfd的字符(有些汉字含该字符的内码)过滤, 而导致程序出错.特别是在做液晶汉字显示时. 针对这个bug.由网友编写了这个补丁. 请下载之后放到你的keilc51in 目录里,运行这个程序.就可以了. 支持v8.02-keil c51 will be at compile time 0xfd characters (some characters with the character code) filter, which led to error. particularly in the so LCD display Chinese characters. To address this bug. prepared by the users of the patch. Please after download put your keil c51 bin directory, run the process. it. support v8.02

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.

其中包含了单片机与5045芯片的通信，读出字节，写入字节！还有单片机的内部时钟定时器，中断等操作！-Which includes 5045 single-chip and chip communications, read byte, write byte! There are single-chip" s internal clock timer, interrupt operation, etc.!
