C++ code for Digital Clock Working

说明：  C classic 100 cases c经典100例(C classic 100 cases c classic)

51控制TB6600驱动步进电机程序，用于通过51单片机控制步进电机的转动与调速功能。

运用加权最小二乘法进行电力系统状态估计 具有较好的收敛性 但适合于较小的系统(Using weighted least squares state estimation of power system has a good convergence, but for smaller systems)

可以再研究非线性动力学问题中计算分形维数的Matlab程序(fractal dimension Matlab algorithm in nonliner dynaimcal systems )

本例程支持wav和IMA-ADPCM的解码需求和相关解码算法，ADPCM解码采用的是ST demo，欢迎大家阅读查看

说明：  一个复杂的智能计算器，可以实现智能计算，以及优先级判断(A complex smart calculator, you can achieve intelligent computing, as well as to determine priority)

说明：  C# 导入导出的execl的帮助类，方便学习和使用(Excl Import and Export Help Classes)

说明：  自己编写的一个VC++程序，打开可执行程序后可以读取wave文件，此时程序将在客户区绘制波形图；之后可以计算短时能量、短时过零率和自相关函数，并且在客户区依次显示函数图像。(own VC prepared by a procedure to open executable wave after reading documents, this process will draw customers District waveform diagram; after short-term energy can be calculated, short-term rates and zero autocorrelation function, District customers in the sequence of images function.)

这是一个Visual C++编写的实现文件随寄存储的小程序,在Visual C++6.0中编译通过.(This is a Visual C achieve document prepared by the pin with a small storage procedures, Visual C 6.0 compile.)
