说明：  SD卡的SPI方式驱动，SPI方式简单速度也可以，很多处理器都有SPI功能，没有也可模拟。(SD card SPI mode driver, SPI is simple speed can, many processors have the SPI function, does not and can simulate.)

very good programs,I hope all members can have a look and learn somthing from it !

此程序是为工控设备增加温度和时钟显示电路源程序。(This program is for industrial equipment increased temperature and clock display circuit source.)

量子通信的论文集合，都是在同方知网，或者是万方上下载的(The paper collection of quantum communication, are in tongfang hownet, or ten thousand square on download )

在Microsoft Visual C++软件环境下，用C++ 语言实现整个仿真。将整个产生系统分为C/A码产生，信号产生，量化三个模块，经过编写和调制实现产生的基本功能，即输入导航电文及控制数据，例如 选取卫星信号，多 普勒频移，采样周期。最后可以得到加入服从高斯分布的噪声信号的数字离散中频信号。 (We use the C++ language to archive the simulation in the Microsoft Visual C++ circumstance. The entire generating system is divided into three parts,including C/A Code, Signal Generating and Quantizer. After writing codes and checking and confirming, I archive the basic functions. If you input the guiding codes and controldata like satellite selecting signal, Doppler frequency movement, sampling period, at last you can get the digital middle frequency signals with gauss distributing noise)

用MFC做的一个学生信息管理系统，有增加、删除、排序、筛选功能，系统通过ODBC方式连接数据库。 由于文库不支持RAR，故需要完整的程序以及数据库可以联系俺，希望对大家有帮助。 (To do with the MFC, a student information management system, increase, delete, sort, filter functions, the system through ODBC to connect to the database. The library does not support RAR, I therefore need to complete the program and database can be contacted, we hope to help.)
