LCD12864(带字库)测试程序,控制器st7920-LCD12864 (with character) test procedure, the controller st7920

讲述了代码阅读的许多技巧，对做二次开发的人员来说，真是葵花宝典啊。-code reading about the many skills to do the secondary development of staff, is a treasury of sunflower ah.

MATLAB 模糊pid 完成了无人机的模糊pid控制器的设计与仿真 含有文章和仿真(MATLAB FUZZY PID wurenjifangzhen)

说明：  设计一个8位的简易频率计，测出信号的频率，即1s内变化的次数。(An 8-bit simple frequency meter is designed to measure the frequency of the signal, i.e. the number of changes in one second.)

可以进行圆柱的拟合，保存成TXT文件，复制到matlab中即可运行(It can fit cylinders, save them as TXT files and copy them to matlab to run.)

把fortran语言转化成c. 呵呵，丰富的fortran语言现在可以方便的使用了-The fortran language into c. Oh, the rich fortran language can now be easily used. . .

CEEMDAN是对EEMD的改进算法，EEMD算法通过加入噪声来减小EMD的模态效应，CEEMDAN算法通过加入自适应的噪声来进一步减小模态效应，而且具有更好的收敛性。(CEEMDAN is an improved algorithm of EEMD, the EEMD algorithm by adding noise to reduce modal effects of EMD, CEEMDAN algorithm by adding noise adaptive mode to further reduce the effect, but also has better convergence.)
