FPGA board based code

说明：  看小说软件，可按键盘快捷键使软件窗口消失和出现以及翻页，可自由调整软件窗口尺寸，本软件可打开已下载好的小说(Read the novel software, keyboard shortcut keys can make the software window disappear and appear, and page turning, can adjust the size of the software window freely, this software can open the downloaded novel.)

说明：  基于gulp的打包流程，简单实用，条例清楚(Packaging process based on gulp)

监测指定目录中的文件目录的改变 ！不错,仅供学习与参考(Monitor changes to the file directory in the specified directory! Yes, for study and reference only)

简易cad，实现了一些cad中的基本功能，vc++编程实现，简单实用-Simple cad, to achieve some of the basic functions of cad in, vc++ programming, simple and practical

Labview双通道信号采集，实现双通道同时采集与数据保存，简单易用(Labview dual channel signal acquisition, double channel simultaneous acquisition and data storage, simple and easy to use)

说明：  采用牛顿法和阻尼牛顿法求解4维无约束极值问题,利用牛顿法确定的搜索方向S，再采用黄金分割法确定最佳步长，所得结果为全局极值点。(Newton method and damped Newton method are used to solve the 4-D unconstrained extremum problem. The search direction s determined by Newton method is used, and the optimal step length is determined by golden section method. The result is the global extremum point.)

NMOS accelerated shutdown circuit

WCS-84坐标系的X，Y，Z与经纬度之间的相互转换(WCS-84 coordinate system X, Y, Z and latitude and longitude between the conversion)

说明：  窗体自适应，统计原始窗体的位置和大小；缩放后Resize通过计算主窗体的大小，计算出长宽伸缩比例，然后再计算出来内部控件的起始点和长宽，过程通过递归完成，简单易行！(The window adapts itself and counts the position and size of the original window; after scaling, resize calculates the length and width scaling ratio by calculating the size of the main window, and then calculates the starting point and length and width of the internal control. The process is completed by recursion, which is simple and easy!)
