SPI接口设计

说明：  FPGA控制外边led，并实现跑马灯等多种效果，用户可以自行控制(FPGA control outside led)

 ；

说明：  数字示波器实验，利用AD、DA和VGA三个外设来实现简易示波器，DA外设发送正弦波给AD外设，AD外设解析成数字信号将数据送给VGA外设进行显示。在VGA上可以看到DA外设发送的波形、波形频率和波形峰峰值。(In the experiment of digital oscilloscope, AD, DA and VGA are used to realize simple oscilloscope. DA peripheral transmits sine wave to AD peripheral. AD peripheral resolves into digital signal and sends data to VGA peripheral for display. The waveform, waveform frequency and peak value of DA peripheral can be seen on VGA.)

实用Verilog编写的SVPWM程序，产生出SVPWM波形，可用于实现同步电机或者异步电机的空间矢量控制算法。(Practical Verilog of SVPWM written procedures, resulting in the SVPWM waveform can be used to implement the space vector control algorithm of the synchronous motor or induction motor.)
