FPGA实现12路pwm

完整的跑表设计，时，分，秒都显示，希望能对大家有用，谢啦(Complete stopwatch design, hours, minutes, seconds, show, hoping to be useful for everyone,)

无线通信调制解调用的verlog和matlab程序，很大很实用。(Wireless modem calls verlog and matlab program, very very practical.)

is61lv25616简单的verilog程序，完成sram读写 主要是基于FPGA(EP2C8Q208I8)下的SRAM驱动(1lv25616 simple verilog program, complete sram read and w1lv25616 simple verilog program, complete sram read)

spi-slave通信的vhdl实现及其仿真(VHDL implementation of spi-slave communication)

在FPGA上实现声卡接口，电子琴，滤波比较器，最终实现语音通信 -In the FPGA to achieve the sound card interface, flower, filter comparators, the eventual realization of voice communications

根据音乐发生的机理，将复杂可编程逻辑器件作为发生音乐的核心器件，用高速集成电路硬件描述语言编程描述发生的音乐乐谱，配合周边硬件电路，由电声转换发声器接收信号，从而发出音乐声，实验表明，采用该方法设计的音乐发生器成本低、修改方便-Music took place in accordance with the mechanism of complex programmable logic device, as occurred in the core of music devices, with high-speed integrated circuit hardware description language to describe the occurrence of music notation, with the peripheral hardware circuits, electro-acoustic conversion by the audible signal device to receive signals, which issued music, experiments show that this method of music generator design and low cost, easy to amend

说明：  使用XILINX公司提供的板子里面的FFT的IP核，很好用(XILINX board provided the use inside the FFT of the IP core, useful)

说明：  ethernet mac vhdl verilog basic

扩频通信的Verilog工程，对从事无线通信的工程人员有参考作用。(Spread spectrum communication Verilog project, engaged in wireless communications engineering staff reference.)

用vhdl编写的主从式代码，会比较接近，它涉及i2c接口，主从式，每行都有注释，我建议如果你想对代码进行编辑就使用灵活的编辑器
