在I2C EEPROM作为奴隶

说明：  基于OV7670采集，SDRAM缓存，sobel处理，VGA显示的工程，内有全部代码，基于QUARTUS开发板实现。 FPGA 边缘检测(Based on OV7670 acquisition, SDRAM cache, sobel processing, VGA display project, with all the code, based on QUARTUS development board. FPGA edge detection)

掌握SDRAM数据读写、刷新、初始化以及FPGA串口收发时序，熟练FIFO IP核的生成和调用。(Master SDRAM data read and write, refresh, initialization and the timing of sending and receiving of the serial port of the FPGA, skilled in the generation and invocation of the FIFO IP core.)

i2c代码 可以从eeprom中写入并读出一字节数据  并用led显示   已调试成功

实现任意整数倍的信号分频，可调，不存在毛刺，波形完整，可运于信号的分析与检测(Arbitrary integer multiple of the signal frequency, adjustable, there is no glitch, waveform integrity, and can transport the analysis and the detection signal)

数字钟通过verilog实现，并且支持Modelsim仿真，通过实验验证(The digital clock is implemented by Verilog and supports Modelsim simulation)

module LDPC (clk,reset,             data_in, data_in_en,             velocity, /*输入信号码率选择*/             data_out, data_out_en,             indication /*输出信号，第一个127要删除前5成7488，指示第一个127*/                );input   clk,reset;input   data_in,data_in_en;input[1:0]  velocity; //码率选择信号output[126:0]   data_out;output  data_out_en;output  indication;

说明：  简单uart，verilog语言编写，已经经过测试，有需要的可以看看(Simple uart, Verilog language, has been tested, you can see if you need it)

本程式為使用Verilog語言寫控制DRAM的控制模塊, 可以簡易的控制DRAM IC, 本程式已經過系統驗證.(program for the use of the Verilog language to write the control of DRAM control module, be easy to control DRAM IC, the program has been systematically verified.)

说明：  EDA软件VCS学习中用到的实际例子，都已经通过调试验证(Practical examples used in the learning of EDA software VCS have been verified by experiments.)

说明：  一本很经典的IC设计中文入门书籍，由任艳颖，王彬编著，翻印几百万册(A very classic introduction to Chinese in IC design book, compiled by Ren Yanying and Wang Bin, reprinted millions of copies)
