Verilog实现 spi接口的FPGA实现 通过仿真，修改后即可应用

FPGA中实现的MSK调制，带modelsim仿真。实际系统测试通过：载波和调制波信号频率可调。调制框图请参见樊昌信 通信原理247页(MSK modulation implemented in FPGA with modelsim simulation. The actual test system: a carrier wave signal and the modulation frequency is adjustable. See Fan Changxin modulation block diagram of communication theory 247)

本源码为Nios II的开发示例,主要演示基于Nios II的uCOS的移植。开发环境QuartusII。 本示例十分经典，对基于SOPC开发的FPGA初学者有很大帮助。(The source code for the Nios II development of examples, mainly based on the Nios II shows the uCOS transplant. Development environment QuartusII. This example is very classic, FPGA-based SOPC development of great help for beginners.)

说明：  发送两个频段的脉冲 个数和频率均可调 发送两个频段的脉冲 个数和频率均可调(pluse and adjust the width of pluse pluse and adjust the width of pluse )

说明：  使用verilog语言实现H.265压缩算法，能够实现实时视频数据的压缩传输(Using Verilog language to realize h.265 compression algorithm can realize the compression and transmission of real-time video data)

*** ***OC_I2C_Master使用说明*** ***** 使用步骤：1.将OC_I2C_Master文件夹拷贝到安装盘alterakits ios2components目录下。 之后重新打开SOPC Builder，在可用元件列表的DeviceSOPC组中将出现OC_I2C_Master 元件，即可像其它Altera外设元件一样添加和使用。 2.hdl文件夹中包含有描述i2c逻辑的硬件描述文件，不能删除。 3.HAL文件夹包含硬件抽象层所需的文件（即驱动），不能删除。 4.inc文件夹包含有定义底层硬件的C语言头文件，不能删除. 5.I2C_doc文件夹下有关于该元件的开发文档。-********* OC_I2C_Master use*********** use these steps: 1. OC_I2C_Master folder will be copied to the installation disk alterakits ios2components directory. Re-open after the SOPC Builder, a list of available devices will appear DeviceSOPC Group OC_I2C_Master components, can be similar to other peripheral devices like Altera add and use. 2.hdl folder contains logical description i2c hardware description files, can not be deleted. 3.HAL folder contains the necessary hardware abstraction layer file (ie drivers), can not be deleted. 4.inc folder contains the definition of the underlying hardware C language header files, should not delete. 5.I2C_doc folder on the developmen

实现4种常见波形正弦、三角、锯齿、方波（A、B）的频率、幅度可控输出（方波 A的占空比也是可控的），可以存储任意波形特征数据并能重现该波形，还可完成 各种波形的线形叠加输出。 -Realize four kinds of common sine wave, triangle, sawtooth, square wave (A, B) the frequency, magnitude controllable output (square wave A, is also a controllable duty cycle), can store arbitrary waveform feature data and can reproduce the waveform, but also completed a variety of linear superposition of the output waveform.
