I2C从设备（Slave） Verilog 代码、设计文档和使用文档，简单、适用：很方便修改工作频率，自定义寄存器接口。-I2C slave (Slave) Verilog code, design documents and user guide, simply to apply: the frequency of easy modification, customized register interface.

VHDL的寄存器读写参考，可自己根据要求重新修改，本示范只做参考用-Register read and write VHDL reference to their request to amend in accordance with, the reference model only

实现fpga与单片机通信，单片机修改一个特定寄存器的值，并数码管显示，fpga给mcu传递一组数值，mcu再通过lcd显示-Communication with the microcontroller fpga implementation, microcontroller changes the value of a particular register, and digital display, fpga to pass a set of values ​ ​ mcu,

内含AD9957的SPI配置程序，输出为单音。目前该程序仅给出三个寄存器的配置，如有需要，简单阅读程序，即可对程序进行修改，本人项目中使用的为该配置程序，能成功输出各种MPSK波形。-The AD9957 contains SPI configuration program, the output is mono. Currently, the program gives only three registers configuration, if necessary, a simple rea
