DDS 正弦波发生器

关于USB开发的verilog开发程序，非常的全面，学习FPGA开发时用得着。(About USB development verilog development process, very comprehensive, learning FPGA development time worthwhile.)

本程序为PCI的协议代码，用Verilog语言编写，还有textbench，经过我们工程验证，能顺利的识别出PCI设备

基于FPGA实现蜂鸣器播放音乐的功能 使用芯片为EP2C8Q208C8N,使用普通蜂鸣器，由于频率不同可实现放歌功能，本例设计的是《友谊地久天长》，使用Verilog语言编程，本例子有工程文件、仿真、波形，经过测试可以使用。(Play music based on FPGA buzzer functions using chip EP2C8Q208C8N, using ordinary buzzer, since the frequency of different functions can be realized sing, in this case the design is " Auld Lang Syne" , using Verilog language programming, this project examples files, simulation, waveform, tested can be used.)

1、FSMC全称是静态存储控制器，用来高速操作外部SRAM，NOR，NAND等，广泛用来驱动LCD MCU的FSMC配置在fsmc_nor.c，你也可以查阅相关资料。 2、此例程通过读写外部M29W128，熟悉FSMC的配置以及操作。(1, FSMC stands for static memory controller for high-speed operation of external SRAM, NOR, NAND, widely used to drive the LCD MCU FSMC configuration in fsmc_nor.c, you can also access to relevant information. This routine by reading and writing external M29W128 familiar with the configuration and the operation of the FSMC.)

说明：  基于OV5640摄像头的视频图像传输存储以及读取。供大家参考。(Video image transmission, storage and reading based on ov5640 camera. For your reference.)

用于ATmega128的一些通讯程序，包含I2C　UART，SPI等接口，用ICCAVR编译(for ATmega128 some communications procedures, including UART I2C, SPI interfaces with ICCAVR compiler)

将串行数据转换为并行的 Verilog 代码。从 rs232 端口的 8 位串行数据转换为 8 位并行数据。

AD conversion using LTC1298

运用VC编程的带LCD显示的信号发生器可用三个开个调节输出三个波形(Signal generator can be used three to open a regulator output waveform using VC programming with LCD display)

说明：  一篇关于LDPC解码算法的FPGA用VHDL实现的PDF文件，老外写的，还可以，可以参考，欢迎大家下载！(A PDF about the FPGA implementation of LDPC algorithm, written by foreigners, but also, you can refer to, welcome to download!)
