基于TCP协议的socket套接口编程小程序，可以在两个进程（一个客户端，一个服务器）之间收发内容，使用了epoll方式I/O复用，内容简洁易懂，是初步学习套接口编程及epoll复用的绝佳例程。

为核心的文本hyperlinkview iOS，精选ios编程学习，很好的参考资料。(As the core of the text hyperlinkview iOS, select IOS programming learning, a good reference.)

该程序实现了对STC单片机的EEPROM的操作。每隔0.5秒钟，单片机对EEPROM进行一次 读、擦除和写操作，并把数值显示到数码管上。 确认试验是否成功：电源上电后，数码管的值在递增，观察值。关闭电源，待几秒后上电， 数码管显示的值会从断电钱的那个值开始显示(The program realized STC microcontroller EEPROM operation. Every 0.5 seconds, the microcontroller on the EEPROM once read, erase and write operations, and the value displayed on the digital tube. Confirmatory test is successful: power-up, the digital value in increments observations. Turn the power off after a few seconds until the power, digital display of the value of money off that value from the beginning to show)
