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.

这个是在参加电子设计大赛时的作品，里面包含了数控稳压电源的设计原理、细节、源码-is participating in the Electronic Design Competition at work, it contains the NC Regulators Power design principle, details OSS, etc.

TEA5767做的数字收音机，具有自动搜台，手动搜台，保存功能-TEA5767 do digital radio with automatic station search, manual station search, save function

本实验实现PS/2接口与RS-232接口的数据传输， PS/2键盘上按下按键，可以通过RS-232自动传送到主机的串口调试终端上（sscom32.exe）； 并在数据接收区显示接收到的字符。 串口调试终端的设置：波特率115200，一个停止位，无校验位。 -Realize this experiment, PS/2 interface with RS-232 data interface, PS/2 keyboard to press the button, through RS-232 automatic transmission to the host serial debug terminal (sscom32.exe) and data receiving display received characters. Serial debug terminal settings: 115200 baud rate, one stop bit, no parity bit.

基于单片机的AD转换器，可以用proteus进行仿真-The AD converter based on single chip, you can use proteus simulation

32 k eeprom c51 源程序 调试通过-32 k EEPROM decoder source debugging through

国外大学生毕业设计，是一个多功能表 单片机用的是ＡＶＲ４８，看看别人的风格，及学习ＡＶＲ很有帮助-foreign university graduates design is a multi-function table is using the SCM AVR48. others look at the style, and learn helpful AVR

单片机控制RTL8019网卡芯片实现TCP/IP协议栈是一件非常有意思的实验。我尝试使用专门针对8位单片机设计的uIP6.0在mcu51-63K仿真器移植成功-SCM control RTL8019 chip Ethernet TCP/IP protocol stack is a very interesting experiment. I try to use specific 8-bit microcontroller design uIP6.0 in mcu51- 63K simulator transplant success

目前市场上有很多语音录放系统，如录放音玩具、录音笔等，大多采用了单片机控制一个语音芯片，再接一个FLASH存储器的结构。单片机可以控制录放时间，选取特定时间段的播放以及单多声道的录放，容易通过改变外接存储FLASH改变录放时间。 我们做的是一个简单模型，只能录放。 只需要录音和放音时的外部 ROSC 端振荡电阻不同就能改变声音的录入和播放速度，录入的时间越短音质越好，录入的时间越长音质越差 它采用模拟量直接存贮技术，因此保真度高，音质好 -Currently on the market there is a lot of voice recording systems, such as sound recording toys, sound recording pens and so on, most of the single-chip microcomputer to control the use of a voice chip, making the structure of a FLASH memory. Single-chip microcomputer can control the playback time, select a specific period of time many of the players, as well as single-channel recording, easy to FLASH memory by changing the external playback time change. We make a simple model, only playback. Required only when the recording and playback-side oscillation of the external resistor ROSC will be able to change different recording and playback of sound speed, the shorter the time of admission, the better sound quality, longer recording sound worse using direct ana
