串口调试,用于测试232串口的通讯正确 串口调试,用于测试232串口的通讯正确()

通过事务查询，连接access数据库，完成页面导航功能(page navigation and location)

求一段音频信号的短时过零率，可用于特征的选取，以及对音频进行分类筛选等场合。(For the sound process)

串口通信处理的多个线程需要协调运行，一个线程必须等待另一线程结束才能开始，在处理一个线程的同时必须把其余待处理的线程挂起等待，以减少其余待处理线程对CPU的资源占用，正处理的线程一旦处理结束则通过线程间的通信发出信号来击活被挂起的线程中的一个线程进入处理。(Serial communication processing necessary to coordinate multiple threads running, a thread must wait until the end of the beginning of another thread in a thread at the same time deal with the need to deal with the rest of the thread to be suspended waiting for in order to reduce the remaining lines to be processed way of CPU resources occupation, is the thread once the deal by the end of treatment inter-thread communication signal to hit live thread was hang a thread into the handle.)

斯坦福大学开发的一个三维点云重构生成网格，进一步生成NURBS曲面并加光照效果的系统。可以实现对生成的三维图形旋转，移动和多个角度图形的拼接(Stanford University in the development of a 3D point cloud generation reconfigurable mesh, NURBS surface generation further increases and the effect of illumination system. Generation can be achieved on the 3D graphics rotation, movement and different angles graphics Mosaic)
