FPGA 蜂鸣器

说明：  通过一个计数器来实现输出信号的占空比要求，可以将duty_cycle分配到拨码开关上,LED分配到发光二极管上,然后调节拨码开关,即可看到LED的亮度发生变化.(The duty cycle of the output signal can be assigned to the dial switch by a counter, and the LED can be assigned to the light emitting diode. Then the brightness of the LED can be seen by adjusting the dial switch.)

verilog xilinx IP实现FFT仿真(Verilog xilinx IP implementation FFT simulation)

都是实验课作业，直接打包的文件，下载之后可以直接跑。

改变学习板上的2个电位器对应的2段模拟输入，实现模拟输入，学员观察数码管的数字变化情况,通过改D[4]的值，实现模拟输出.(Changing the learning board two potentiometers corresponding paragraph 2 analog inputs, analog inputs, digital tube digital trainees observe the changes, by changing D [4] value for analog output.)
