DRV8880驱动程序，各位看官好好学习吧，我就不多介绍了！(DRV8880 driver program, you officers to study well, I will not introduce more!)

compiler programming, code something

IEEE33无功优化，遗传算法，牛顿拉夫逊潮流算法(Reactive Power Optimization of IEEE33, Genetic Algorithms, Newton Raphson Power Flow Algorithms)

Jsp上传图片并裁切，并可放大图片，可作为用户中心的头像图片裁切上传功能，基于jquery内核的图片裁切，需要注意的是，用document. ready事件中在上传后第一次转向时无法获取到图片的打开，应该是没有被下载来的缘故。可以拖动图片以裁剪满意的头像。头像图片的大小应不大于2.5M。

说明：  基于python的bp神经网络人脸性别识别(Python-based BP neural network face gender recognition)

说明：  当矩阵数据在第一列具有相同值时，讲他们分组到变量中(Grouping matrix data into variables when they have the same value in the first column)

说明：  ufmod 1.25.2a source code for windows

经验正交算法，和大家一起分享魏凤英老师编写的eof程序，改程序已经过检验确实有效(EOF University Corporation for Atmospheric Research NCAR Command Language Version 6.2.1 The use of this software is governed by a License Agreement)

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.)

VC++ Windows字体预览程序，先获取到Windows所安装到的所有字体，用户选择任一字体后，可看到下面一行字自动应用于该字体形式，并且下面有几个选项：粗体、斜体和下划线效果，点击这些操作，字体预览效果中会看到这些变化。
