用CPLD驱动扬声器实现音乐的播放，程序是用VERILOG写的，

这是使用systemgenerator的一个入门程序和范例使用matlab和system generator共同实现，并配有教学文档，清晰简单，易懂(This is an entry using systemgenerator procedures and examples using matlab and the system generator together to achieve, and with a teaching document, clear and simple and easy to understand)

说明：  基于fpga的spi通信测试 可与stm32进行spi通信测试(SPI communication test based on FPGA can test SPI communication with stm32)

说明：  资料是本人根据相关文献资料用vhdl语言编写的旋转机械鉴相信号倍频的程序，multifre1.vhd是倍频程序，multifre1.vwf是仿真波形文件，stp1.stp是虚拟逻辑分析仪signaltap文件。该倍频程序可以直接使用，可以设置倍频数，修改实体参数N即可。(According to the literature data is the information I have written in with vhdl Rotating Machinery Kam believe that the procedure multiplier number, multifre1.vhd is the multiplier process, multifre1.vwf is the simulation waveform files, stp1.stp a virtual logic analyzer signaltap file. The multiplier process can be used directly, you can set the multiplier number, modify the parameter N can be solid.)

HDMI协议的Verilog实现，通过对RGB三个通道分别进行TMDS编码完成，纯原创代码(Verilog implementation of HDMI protocol, through TMDS coding of RGB three channels, pure original code)

每次开机都将次数加1 并存储到EEPROM。这样就能直观的看到机器的使用次数 用P1口 LED做为显示，次数大于256是将溢出，按复位模拟开机 或者直接通过开关开机(Each boot will add a number of times and stored to the EEPROM. So you can visually see the frequency of use of the machine as with P1 port LED display, the number is greater than 256 will overflow, analog power or press the reset switch power directly through)

通过CPLD将8位并行数据转换为串行数据并可以采用I2C方式与其他器件连接，可以用于MCU需要与提供I2C接口器件通信的场合。-through CPLD to eight parallel data into serial data and methods can be used I2C connections with other devices, which can be used to provide MCU with I2C Interface Communications occasions.
