开关、 灯、 和多路复用器-DE2-115

FPGA测试程序，仅供测试硬件是否能够运行，主要功能是点亮运行指示灯(The main function of the test program of FPGA is to light the running indicator.)

这是很全的标准库啊，不是1164.vhd，都是一些加，乘，除，平方等操作的包来的．-This is the standard for the whole ah, not 1164.vhd are some increases, multiplication, addition, operational square packages to come.

占空比1：1的通用分频模块-1:1 generic-frequency module

给FPGA程序，使之产生信号，驱动AD7606读取数据，并行模式。(give FPGA signal to read AD7606)

rc6 algorithm designed based on verilog and is verified

在VHDL结构体中用于描述逻辑功能和电路结构的语句分为顺序语句和并行语句两部分，顺序语句的执行方式十分类似于普通软件语言的程序执行方式，都是按照语句的前后排列方式顺序执行的。(VHDL structure in the body used to describe the logic function and circuit structure of the order of statements and expressions are divided into two parts in parallel statement, modalities for the implementation of the order of statement is very similar to ordinary language software program implementation, are in accordance with the statements before and after the arrangement of the order implementation.)

VHDL programmes for basic digital circuits. begineers can learn easily

说明：  基于FPGA设计的串口发送及接收程序，波特率可调(FPGA - based serial port sending and receiving)

电梯控制，包括楼层按键相应，显示上下状态。(Elevator control, including the floors of the corresponding button to show the whole state.)

利用FPGA实现USB芯片CY7C68013与上位机的进行通信的系统，代码采用VHDL语言实现，利用状态机实现FPGA控制USB的数据传输，传输时序采用SLAVE FIFO实现
