nand flash controler verilog

说明：  Verilog教程，小梅哥FPGA自学与验证(a basic book of how to learn Veriolg)

在BASYS3上实现跑马灯的功能。第一LED交替闪烁；第二LED由左至右逐个变亮，再逐个变暗；第三LED由右至左逐个变亮，再逐个变暗；第四LED由两边逐个变亮，再从中间逐个变暗。(Realize the function of the horse light on BASYS3. The first LED flashes alternately; second LED brightens from left to right and then darkens one by one; the third LED turns from right to left, then darkens one by one, and then darkens one by one; fourth LED is brightened by both sides, and then darkening from the middle.)

说明：  基于ALINX AX7020硬件平台的USB-OTG通信程序。操作系统采用uCOS III v1.41，基本实现了双向USB2.0 块传输（Bulk Transfer）通信，zynq的PS端接收USB数据并回传至主机。经测试，主机端Window10系统采用libUSBK编程时，采用64字节的块时，传输速率可达210Mbps。zynq开发工具为Vivado2015.4，程序包中包含了全部的硬件和软件工程文档。(A USB-OTG communication project where an AX7020 platform is employed as USB device. The embeded operating system is uCOS III of version 1.41, and the FPGA toolchain is Vivado 2015.4. This project implements a full speed bidirectional USB2.0 bulk transfer. A test on Windows 10 host with libUSBK shows that the transfer speed is up to 201Mbps.)

采用倍频及1/3、1/12倍频绘制的路面不平度频谱图（自编）(Using octave and 1/3, 1/12 octave drawn road roughness spectrum (self))

tle转换为六根数的c++源代码，英文原版代码，测试可用(tle converted to six the number of c++ source code, the English original code, test available)

SPI slave接口协议，基于verilog，调试可用

基于verilog的FFT设计，使用vivado作为开发平台(Verilog based on the FFT design, the use of vivado as a development platform)

这是 picoblaze 的线跟踪 bot 程序集代码。

实用Verilog编写的SVPWM程序，产生出SVPWM波形，可用于实现同步电机或者异步电机的空间矢量控制算法。(Practical Verilog of SVPWM written procedures, resulting in the SVPWM waveform can be used to implement the space vector control algorithm of the synchronous motor or induction motor.)

使用VHDL编写数字蜂鸣器音乐，整个项目文件，可直接使用 (Use VHDL to write 1602led driver, the entire project file, and can be used directly.)
