基于电压正反馈的逆变器并网孤岛检测技术，simulink仿真有较好的介绍，是学习孤岛检测的好资料。(Based on the positive feedback voltage inverter grid islanding detection technology, for a better introduction to simulink simulation.Islanding detection is learning good information.)

基于星研集成环境的51单片机的电子钟设计与实现，源码是用汇编语言写的，有需要的可以下载参考下，谢谢(Design and implementation of electronic bell 51 single integrated environment based on satellite research, source code is written in assembly language, there is a need to download reference, thank you)

说明：  读取三轴陀螺仪数据，用1602显示，能够显示三轴的角加速度与加速度(rtyuiopghjkl rtyutfyvv ugvugubu)

Mapreduce实现的TF-IDF词频统计分析，可以直接运行于HADOOP环境下(Analysis of TF-IDF statistical Mapreduce to achieve, can be directly run in HADOOP environment )

Alarm / launcher Implemented all the basic functions and features: timer, playing Call (wav), running an application / document, save the settings (manual and automatic), autoloading and avtosvorachivanie (being involved and switchable by the user), the player calls (wav ov), with which you can lose wave y in the right directory and select it by double-clicking.

C8051实现台达变频器驱动和控制，Modbus协议，Keil下编译通过。(C8051 for Delta inverter drive and control, Modbus protocol, Keil compile.)

说明：  STC89C52RC 单片机开发板慧净HL-1 115个例程(Stc89c52rc MCU development board Huijing HL-1 115 routines)

Microchip公司原版写的hcs301滚动码芯片解码程序,注解十分详细，使用低端的pic16c54实现。(Microchip s original written hcs301 rolling code decoder chip, very detailed notes, the use of low-end pic16c54 implementation.)

本实验将实现如下功能：开机的时候先检测SD卡和SPI FLASH是否存在，如果存在则获取其容量，并显示在LCD上面（如果不存在，则报错）。之后开始USB配置，在配置成功之后就可以在电脑上发现两个可移动磁盘。我们用DS1来指示USB正在读写，并在液晶上显示出来，同样，我们还是用DS0来指示程序正在运行。(This experiment will achieve the following functions: when booting, first detect the existence of SD card and SPI FLASH, and if there is, obtain its capacity, and display it on the LCD (if not, report an error). Then the USB configuration is started, and after the configuration is successful, two removable disks can be found on the computer. We use DS1 to indicate that the USB is reading and writing, and display it on the LCD. Similarly, we use DS0 to indicate that the program is running.)
