Motor Control PWM wave generated by the procedure, VHDL language

本代码用verilog语言配合sopc和nios实现了串口调试的目的。软件编程用C语言描述，只是比较简单的例子，适合初学者做了解用，本人亲自在EP2C8Q上实践。(The code to use verilog language sopc and nios achieved with serial debugging purposes. Software programming using C language description, but relatively simple example for beginners to do with understanding, I personally EP2C8Q on practice.)

说明：  利用FPGA实现对外设按键的控制，例如用户库用按键控制跑马灯的效果(FPGA is used to realize the control of external keys, such as the effect of user database using keys to control the running horse lamp)

dpim是光通信中使用的一种调制方式，这里提供的是它的环回代码，自己可以根据需要拆开了下载到两块板子上。(dpim is used in an optical modulation, here is its loop-back code, they can download needed two apart on the board.)
