具有多种功能的电子钟：闹钟、定时和修改…

说明：  基于ofdm系统的各个模块的VHDL程序，软件是用的ISE仿真的。绝对有用。(Ofdm systems based on VHDL program of each module, the software is to use the ISE simulation. Absolutely useful.)

LabVIEW FPGA SPI implementation

本verilog代码通过IIC总线实现了对 PCF8591AD、DA转换芯片的控制。适用于FPGA，亲测可用。(this is used for FPGA to control PCF8591(AD/DA) chip by verilog.)

verilog编程语言的讲解，有电子科技大学出版(verilog programming language to explain, there is the University of Electronic Science and Technology Publishing)

常见的几种电机的特征与控制方法-Several common characteristics of the motor and control method

:针对现场可编程门阵列(FPGA)芯片的特点,研究FPGA中双向端口I/O的设计,同时给 出仿真初始化双向端口I/O的方法。采用这种双向端口的设计方法,选用Xilinx的Spartan2E芯片 设计一个多通道图像信号处理系统。-: For field programmable gate array (FPGA) chip features of FPGA in the bi-directional port I/O design, the simulation is initialized at the same time two-way port I/O method. Using this design method of two-way ports, optional Spartan2E the Xilinx chip to design a multi-channel image signal processing system.

基于verilog的FFT设计，使用vivado作为开发平台(Verilog based on the FFT design, the use of vivado as a development platform)

Verilog HDL编写的键盘扫描程序，考虑了判断按键弹起的问题。程序按一定的频率用低电平循环扫描行线，同时检测列线的状态，一旦判断有一列为低则表示有键被按下，停止扫描并保持当前行线的状态，再读取列线的状态从而得到当前按键的键码；等待按键弹起：检测到各列线都变成高点平后，重新开始扫描过程，等待下一次按键。-Written in Verilog HDL keyboard scanner, taking into account to determine key bounce problem. Program according to a certain frequency of scan lines with low-level circulation lines, while testing out the state line, once the judge has said there is a classified as low-key is pressed, stop the scan and to maintain the current line-line state, and then read out line state to get the current keys key codes to wait for key pop-up: To detect the lines at all out into a high level after the re-start the scanning process, waiting for the next key.

该程序实现的是10进制的计数器，具有置位复位的功能。-the program is the band of 10 counters, with the home-reset function.
