超级Socket框架，支持各类TCP/IP服务器快速实现(super Socket framework, all TCP/ip server types included)

Arduino32路舵机控制板的控制程序，利用51单片机所接的矩阵键盘通过异步通信向Arduino控制板发送其规定的字符串指令，使舵机控制板控制舵机实现其预先在PC上通过软件设定好的动作。控制舵机机器人时非常好用的程序。(The servos control panel in Arduino32 Road control program using 51 microcontroller connected matrix keyboard through a the asynchronous communication the Arduino control panel sends its provisions string instruction, the steering gear control panel to control the steering gear to achieve its set through the software on the PC in advance given a good action. Control the steering robot is very easy to use program.)
