DMX512控制器程序，实测能用，给有学习需要的人

Microsoft Visual C++ MFC串口通信编程详解,主要介绍了用CreateFile()函数和WriteFile()函数读写串口的实例,以及设置 串口属性的实例. 在工业控制中,工控机(一般都基于 Windows 平台)经常需要与智能仪表通过串口 进行通信.串口通信方便易行,应用广泛. 一般情况下,工控机和各智能仪表通过 RS485 总线进行通信.RS485 的通信方式是 半双工的,只能由作为主节点的工控 PC 机依次轮询网络上的各智能控制单元子节点. 每次通信都是由 PC 机通过串口向智能控制单元发布命令,智能控制单元在接收到正 确的命令后作出应答. (Microsoft Visual C++ MFC serial communication programming explain CreateFile () and WriteFile () function to read and write the serial port of the instance, and set the serial port attribute instance in industrial control, IPC (generally based on the Windows platform) often need to communicate with the smart meter through the serial port serial communication easy and widely used normal circumstances, the IPC and intelligent instrument through RS485 communication RS485 communication is half-duplex, only as the primary node industrial PC turn polling network intelligent control unit child nodes. every communication from a PC via the serial port to issue commands to the intelligent control unit, intelligent control unit receives the correct command response.)

学习matlab的方程小程序，没问题额的啊(Learning matlab equation applet, the amount is no problem)

采用openGL实现的类型于画板的工具，可绘制多种基本的图形，提供一个功能面板，可选中多个图形，进行平移旋转，复制删除，线条粗细改动，反走样，填充模式切换。支持拾色器，也可使用滑动条更改颜色，图片可保存至本地(OpenGL implemented using type tools in Sketchpad can draw a variety of basic graphics, provides a function panel, multiple graphic pan rotation, copy delete, line thickness changes, anti-aliasing, fill mode. Support Color Picker, or use the slider to change the colors, images can be saved to a local)

说明：  本系统采用下位机负责模拟数据的采集,从51单片机负责采集数据，并应答主机发送的命令，上位机即主机是负责处理接受过来的数字量的处理及显示，主机和从机之间用RS-485进行通信。这样用户可以在上位机上编写各种程序对文件中的数据进行有效查询和分析,有利于工业过程的长期正常运行和检查。该系统采用的是STC89C52单片机，此芯片功能比较强大，能够满足设计要求。(In this system, the lower computer is responsible for the acquisition of analog data, and the 51 single chip microcomputer is responsible for collecting data and answering the commands sent by the host computer. The host computer is responsible for processing and displaying the received digital quantity. The communication between the host computer and the slave computer uses RS-485. In this way, users can write various programs on the upper computer to effectively query and analyze the data in the file, which is conducive to the long-term normal operation and inspection of industrial processes. The system uses STC89C52 single chip microcomputer, which is powerful and can meet the design requirements.)
