多功能数字钟，在quartusII软件平台上实现的verilog源代码。大家试试看。(Multifunctional digital clock in quartusII software platform to achieve the verilog source code. We try.)

说明：  控制步进电机转动，正反转，旋转角度完美掌握。很好用，亲测(Control stepping motor rotation, positive and negative rotation, perfect control of rotation angle. Very easy to use, personal test)

说明：  LDPC码的FPGA实现，用verilog语言编写(FPGA implementation of LDPC code, written in Verilog language)

通过VHDL语言进行数字信号处理的FIR操作，可以很好的实现滤波功能，有很好的作用，-Through VHDL languages digital signal processing FIR operation, can good realization filtering, have good role

出租车vhdl程序，并带有testbench仿真程序，通过开始按键复位，然后根据行使信号进行公里计数，起步价3公里8元钱，超过3公里一公里1元钱(Taxi vhdl program, with a testbench simulation program, started by the reset button, then the exercise kilometer count signal, starting at 3 km 8 yuan, more than three kilometers one kilometer dollar.)

这是基于verilog hdl的数字时钟源代码，能够实现时分秒的计时，可以手动进行调时与调分。(This is based on the digital clock verilog hdl source code, can be achieved when every minute of the time, you can adjust the time manually adjusting points.)

改VHDL代码可以实现超声波测距的功能，其精确度达到US级，可以用七段数码管显示其数值(sound ranging sound ranging sound ranging sound ranging sound ranging sound ranging sound ranging sound ranging sound ranging sound ranging sound ranging )

交通灯通过数码管显示，几种模式可调，还可以时间可设，适合初学者入门参考学习。(LED traffic lights can be set to several modes adjustable time beginners reference ~ ~ ~)
