基于STM32的RA8875控制LCD

CS5460芯片在MSP430单片机中的应用(Application of CS5460 chip in MSP430 single chip microcomputer)

常用RS232串口通用库类，可直接使用,谢谢大家~(The common library of the RS232)

set_white,matlab一算算法最短路径的选取，最详细的程序。(set_white matlab count shortest path selection algorithm, the most detailed procedures.)

用贪婪算法中的哈夫曼编码为文件进行压缩，得到一个比较好的压缩程序．-greedy algorithm with the Huffman encoding of the document for compression, to be a relatively good compression process.

说明：  Arduino hx711库文件，在编写程序省去很大力气，很好用的头文件，大力推荐(Arduino hx711 library files, eliminating the need to write programs in a lot of effort, a good use of header files, strongly recommended)

实现在线监测数控机床的振动信号，并存入计算机数据库内(Realize online monitoring of vibration signals of CNC machine tools and store them in computer database)

说明：  STM32 FFT积分处理加速度信号到速度、位移(STM32 FFT integrates acceleration signals into velocity and displacement)

tcp通信测试，编写tcp通信相关方法和实现，可以用来测试tcp通信是否可以连通传输和接收数据，作为客户端，获取到服务器端的ip和窜口号，然后进行连接，这只是一个简单的样例，可以方便大家测试，和研究tcp是怎么接收和传输数据的。

数字识别之网络神经算法，功能强大，十分好用。希望和大家共享。(Digital Identification of neural network algorithm, a powerful, very easy to use. Would like to share.)

主要用途是对抗多径衰落。由于多径衰落的存在，使得同一个帧由于路径不同，到达用户端的时延有先有后。在相关的频域上的会造成子载波之间的相互干扰，影响 性能。另外，由于有了循环前缀，使得IFFT FFT操作把原来的线性卷积变成循环卷积，大大简化了相应的信号处理复杂度(The main purpose is to fight against multipath fading. Due to the presence of multipath fading, the first after they have the same frame different paths to reach the client delay. Would cause mutual interference between sub-carriers in the frequency domain, affecting performance. In addition, thanks to the cyclic prefix, so IFFT FFT operation to the linear convolution of the original into a circular convolution, greatly simplifying the corresponding signal processing complexity)
