利用Quartus 综合简单的计时器功能，欢迎大家下载、参考。谢谢大家的支持！

Verilog 我认为写的非常好的细节书(Verilog In my opinion written details of the book)

说明：  基于FPGA的信号发生器，产生了正弦波，方波，锯齿波和三角波四种波形，按下一次按钮，波形切换一次。按下另一个按钮，改变波形的频率(The signal generator based on FPGA can generate four kinds of waveforms: sine wave, square wave, sawtooth wave and triangle wave. Press the button once and switch the waveform once. Press another button to change the frequency of the waveform)

说明：  基于fpga的数字图像处理原理及应用源码(The principle and source code of digital image processing based on FPGA)

ENDAT 协议说明，包括时序等详细的说明，(endat Encoder characteristics)

通过EMIF连接fpga与dsp的代码-Through the EMIF connection FPGA code with dsp

本文介绍了在数字下变频(DDC) 中的抽取滤波器系统设计方法和具体实现方案。采用CIC 滤波器、HB 滤波器、FIR 滤波器三级级联的方式来降低采样率。通过实际验证,证明了设计的可行性(This article describes the digital down conversion (DDC) of the decimation filter system design methods and concrete realization of the program. Using CIC filter, HB filter, FIR filter cascade three-level approach to reduce the sampling rate. Through the actual authentication, to prove the feasibility of the design)

/功 能：1.实现与CPLD的通信,从而控制PWM的占空比. 2.实现LCD显示相关信息. // 3.实现对键盘按键的判断和确定相应的操作. 4.实现对电压电流的检测. // 5.实现过载保护功能,电流过大时,切断PWM输出,当排除过流故障后,自动恢复供电 // 6.实现用PID算法跟踪电压,实现稳压输出(/ Function: 1. Achieve communication with the CPLD to control the PWM duty cycle. 2 LCD Display relevant information.// 3. Realize the keyboard keys judgment and determine the appropriate action. 4. Achieve the voltage and current Detection// 5. achieve overload protection, current is too large, cut off the PWM output, when excluding overcurrent fault, automatically restore power// 6. achieve tracking voltage with PID algorithm to achieve the regulated output)
