C51音乐程序(八月桂花) [功能] 通过单片机演奏音乐 //本例采用89C52, 晶振为11.0592MHZ //关于如何编制音乐代码, 其实十分简单,各位可以看以下代码. //频率常数即音乐术语中的音调,而节拍常数即音乐术语中的多少拍 (C51 music program (August Osmanthus) [function] through Singlechip music// this case, using 89C52, crystal for 11.0592MHZ// on how to prepare music code is actually very simple, you can see the following code.// Frequency music terminology that is constant in tone, and the beat of music terminology that is constant in the number of pictures)

Ftp客户端与服务器VC++完整版，是一个比较简单的ftp程序，但是程序提供了各种接口，能够让读者看法出各种复杂的ftp程序，程序中的各个程序模块均已经实现，以上所有程序在VC6.0中调试通过 　　目录ftp服务器是一个基于控制台的ftp服务器程序，能够实现大部分的FTP的服务器程序； 　　注意： 　　 a.帐号密码为toldo 　　 b.主目录为c:/temp,在连接之前请先建立(Ftp client and server, the full version of VC++, is a relatively simple ftp program, but the program offers a variety of interfaces, allowing readers to view a variety of complex ftp program, proceedings have been achieved in all program modules, all of the above procedures In VC6.0 debug directory ftp server through a console-based ftp server program, able to achieve most of the FTP server program Note: a. account password toldo b. the main directory is c:/temp, in connection before you build)

使用keil5编写的STM32输出四路互补的PWM，适配正点原子的mini版，同样是为电赛逆变系统做的准备。通过定时器的输出比较模式，在PC6~PC9，输出4路PWM，每路PWM频率为500Hz，占空比为50%，每一路PWM相位差为45°(The STM32 output four complementary PWM, which is written in keil5, is suitable for the mini version of the positive point atom, which is also the preparation for the electric match inverter system.Through the output comparison mode of the timer, in PC6~PC9, the output 4 road PWM, the PWM frequency of each road is 500Hz, the duty ratio is 50%, and the PWM phase difference of each road is 45 degrees.)

ch372模拟键盘例程，在pic单片机上的移植,用pic单片机控制ch372芯片，来模拟一个虚拟键盘，对应按键后发送F1-F4之类的模拟键盘的值，此程序用usb的外部固件模式来模拟键盘。

自己写了一个主线程等待多个线程执行.有二种方式去进行。对多线程很有帮助。(Write a main thread waits for multiple threads of execution. There are two ways to proceed. Multi-threaded helpful.)
