DDR3读写

说明：  我测试过的！Verilog HDL实现RS编码。(I' ve tested it! RS coding Verilog HDL implementation.)

fpga verilog实现 S29GL256S 系列 并行 nor flash 的读写擦除操作功能。 verilog源代码。(Verilog S29GL256S to achieve FPGA series parallel flash nor read and write erase operation function. Verilog source code)

da6578的IIc时序驱动verilog，次代码仿真验证通过，有需要的同志可以下载下来参考，同时需要IIC时序的操作，也可以下载下来进行参考来做一些相应的接口时序来完成你们对应的工作。  

说明：  ahbsram contains all codes of sram

在Nexys4开发板上实现一个时钟的显示，利用了视觉暂留的功能实现数码管的输出，但因为时间问题，小时的位数只设计了一位，需要两位的话加一位即可。

FPGA与PC端实现串口数据的收发，先从PC端接收数据，然后发回给电脑，可通过串口助手验证。(The serial port data is sent and received between the FPGA and the PC. First, the data is received from the PC, and then sent back to the computer. It can be verified by the serial port assistant.)

内容有VHDL语法总结及相应的实例应用，每个程序我都亲自试过，特别适合初学VHDL的同学们。常用的程序有 设计一个M序列发生器，M序列为“11110101”、 设计一个彩灯控制器，彩灯共有16个，每次顺序点亮相邻的四个彩灯，如此循环执行，循环的方向可以控制。设计一个跑马灯控制器。一共有8个彩灯，编号为LED0~LED7，点亮方式为：先从左往右顺序点亮，然后从右往左，如此循环往复等等。这些都是我在考试前熬夜总结的，很有用。如果配合开发板用的话，那就更好了 ( VHDL syntax summary content and the appropriate application instance, every program I have personally tried, especially for students of beginner VHDL. Common program has designed a sequence generator M, the M series is 11110101 , a lantern controller design, a total of 16 lights, each sequence of four adjacent lights lit, so the cycle execution cycle direction can be controlled. Marquee design a controller. A total of eight lights, numbered LED0 ~ LED7, the lighting way: first left to right order of light, and then right to left, so the cycle and so on. These are all I stay up all night before the exam summary, very useful. When combined with the development board, then so much the better )

verilog代码，串口发送接收代码，含有源代码和测试文件，准确可用(verilog code for serial port transmit and receive code, with source code and test files, and accurate available)

800 x 600 60 hz VGA 控制器。简单的 verilog 代码。软件项目包括。
