手写数字

说明：  这个代码实现的功能是输入两个波形，让两个波形进行卷积计算，最后输出到缓冲区，送到输出口(This code implements the function is to enter two waveforms so that the two waveform convolution calculation, the final output to the buffer and sent to the output port)

说明：  用stm32f103控制无源蜂鸣器播放音乐(Using STM32F103 to control passive buzzer to play music)

8250可编程通讯接口实验，这是很好的8051F单片机初学者的资料(8250 programmable communication interface experiment, which is a good beginner information 8051F microcontroller)

说明：  这是一个傅里叶变换与傅里叶逆变换的程序代码，是一个子函数与主函数的合集，分别为不同文件(Fourier transform)

mysql接口访问动态库,用于C++中访问mysql数据库，int iRet = mysql_query(&m_mySQL, strSQL.c_str()); MYSQL_RES* m_myRs = mysql_store_result(&m_mySQL); pRs->m_myRows = (DWORD)mysql_num_rows(pRs->m_myRs);等接口用于mysql数据库编程

cather使用手册。介绍cather的使用，图解(cather manual. Introduction cather use, graphical)
