dynacube控件升级

说明：  北京航空航天大学的多旋翼飞行器的PPT压缩包，对于想学飞控的玩家很有用(The PPT of the Beihang University's multi rotor aircraft is very useful for players who want to learn flight control.)

VC++可切换到数字模式的圆形时钟，VC++编程学习源码，很好的参考资料。(VC++ round the clock to switch to digital mode, VC++ programming learning source, a good reference.)

本程序使用的是RFID-RC522射频模块设计的一个门禁系统，当感应卡放到射频模块区域内会感应到卡，如果卡序列号和程序设计一致就会认为是正确开锁，D2指示灯亮，LCD上显示开锁，5秒钟以后自动关锁，D2指示灯灭。当卡错误时候不会显示，D2也不会亮。卡的序列号是唯一的。卡感应距离45mm以内，钥匙感应35mm以内。

本程序是实现VC控制操作的小例程，可实现属性页，列表框、编辑框等多种控件的操作。适合初学VC的同学参考。(This procedure is to achieve VC control operation of small routines, enabling property pages, list box, edit box and other control operations. Suitable for beginners VC reference students.)

POJ141的源代码，以空间换时间，速度很快很好用。(POJ141 the source code for time in space, fast easy to use.)

用Csharp做的AutoCAD的二次开发，实现dwg文件的读取显示，保存(Csharp do secondary development of AutoCAD, the dwg file read, save)

包含光伏电池模块、MPPT模块、BOOST模块、逆变模块，基于欧几里得距离的聚类分析，MIMO OFDM matlab仿真。( PV modules contain, MPPT module, BOOST module, inverter module, Clustering analysis based on Euclidean distance, MIMO OFDM matlab simulation.)

蓝牙编解码代码,开源代码,资源非常不好找(Bluetooth codec code, open source code, resources are very difficult to find)

说明：  网上教材体系，包括图书展示，模糊检索，全词搜索，购物车系统，订单管理等(Online textbook system, including the books show, fuzzy search, full-word search, shopping cart system, order management, etc.)
