说明：  fpga配置锁相环完整程序，使用quartus IP核，Verilog语言。(FPGA configuration PLL complete program, Verilog language.)

按键控制led灯亮灭顺序，从左到右跑或者从右往左跑(Press button to control the LED lights on and off)

EP2C35A实验箱基于NIOSII的串行AD_DA编程(EP2C35A experimental box based NIOSII the serial AD_DA programming)

vhdl,无进位同步计数器，完成6进制加，输出6进制序列数-vhdl, non-binary synchronous counter to complete the six binary Canada, output 6, the number of binary sequences

verilog hdl 编写的64点fft代码，适合很多芯片(coded by verilog hdl that implement 64 point fft, suite to many core)

说明：  可以获取各种字符，并在数码管显示出来，非常的靠谱且稳定(Various characters can be acquired and displayed on the digital tube.)

8位十六进制频率计设计 根据频率的定义和频率测量的基本原理，测定信号的频率必须有一个脉宽为1s的输入信号脉冲计数允许信号；1s计数结束后，计数值被锁入锁存器，计数器清零，为下一测频计数周期做好准备。测频控制信号可由一个独立的发生器（FTCTRL）来产生。-8-bit hexadecimal Cymometer designed in accordance with the definition of frequency and frequency of the basic principles of measurement to determine the frequency of the signal must have a pulse width of the input signal for 1s permit pulse counting signal 1s counting after the total value was locked into the lock depositors, counters cleared for the next count cycle frequency measurement ready. Frequency control signal generator may be an independent (FTCTRL) to generate.
