quartus环境下开发的三人表决器（三种不同的描述方式）maxplusII兼容...

Altera QUARTUS 7.2的矩阵键盘电子琴完整工程（含源码），在EP2C20芯片上实现-Altera QUARTUS 7.2 Project of matrix keyboard electronic organ, implement on EP2C20 chip.

红外接收处理，根据外部波形记录波形的高低电平时间，从而得到波形数据。(Infrared receiver processing, according to the external waveform waveform record high and low times, resulting waveform data.)

该代码使用 FSM 3 线串行 eeprom 与 fpga 的接口。它是由微芯片定义的接口。 该代码在串行 EPROM 中存储来自 ADC 的偏移量的错误。

数字钟电路的实现，可以24小时计时，可调整时间！(Digital clock circuit implementation, a 24-hour timer, adjustable time!)

Real time Clock DS1307 interacing with PIC using I2C.

本代码实现了全加器的功能，可供初学者学习-This code implements a full adder functions, for beginners to learn

说明：  功能是（用Verilog语言的，内有比较详细的注释）： （1）计数器的功能是从0到9999计数，并能以十进制数的形式在七段数码管上显示出来(包括七段数码管显示模块). （2）该计数器有一个1个nclr和一个adj_plus端，在控制信号的作用下（见下表），计数器具有复位、增或减计数、暂停的功能。编写以上的程序的完整模块. 计数器的功能表 nclr adj_minus 功 能 0 0 复位为0 0 1 递增计数 1 0 递减计数 1 1 暂停计数 (Function is (with Verilog language, the more detailed comments): (1) counter function is from 0 to 9999 counts, and are able to form a decimal number on the seven-segment LED display (including the seven-segment LED display module). (2) The counter has a one nclr and a adj_plus side, under the action of the control signal (see below), the counter has reset, increase or decrease of count pause function. Complete the preparation of the above program modules. Counter function menu nclr adj_minus reset 0 0 0 0 1 1 0 counts counting suspended Count 1 1)

Modified rom based logic

基于VHDL语言的串口发送和接收程序,自己调试通过，并已经运用在工程中(Based on the serial port to send and receive procedures VHDL language, its own debugging, and has been used in the project)
