FPGA realize for a good vga display routines, vhdl language.

说明：  用FPGA于32进行SPI单向通信，FPGA向32放松发送数据(One-way SPI communication is carried out in 32 with FPGA, and data is sent to 32 with ease by FPGA.)

vga编程。实现3种模式的vga控制，分别产生横彩条，竖彩条，棋格彩条的显示-vga programming. Realization of the three-mode vga control, generate horizontal color of the color of the shaft, and the chess grid color of the show

基于VHDL语言的DPLL电路的设计，给出了设计方案和部分源代码 (DPLL)

PC104总线的CPLD代码，调试已经通过，可以修改应用到其他的工程(PC104 bus CPLD code, debugging has been passed, you can modify the application to other engineering 示例用法:)

说明：  AD9250是一款双通道14位ADC，最高采样速率250 MSPS，JESD204B Subclass 0或Subclass 1编码串行数字输出(The ad9250 is a dual channel 14 bit ADC with a maximum sampling rate of 250 MSPs and jesd204b sub class 0 or sub class 1 coded serial digital output)

altera官方的各种有用的参考资料，都是自己收集的，遇到问题可以很方便的查看(altera official variety of useful references, are their own collection, problems can easily view)

depends on irda transmitter recever

电梯的vhdl设计，6层楼含开关门，警报，内部请求，外部请求-Vhdl elevator design, six floors with switch doors, alarm, internal requests and external requests

说明：  在FPGA实验操作系统实现ASK,FSK,PSK的调制解调，基带信号由M序列发生器产生，经过AD模块在示波器上进行显示，精油DA模块在同一块实验板上进行解调操作，生成信号控制LED灯的亮灭，并与调制输出信号在示波器上同时展示，并进行对比。基带信号为3MHz。(In the FPGA operating system experiment implementation ASK, FSK, PSK modulation and demodulation of the baseband signal generated by the M sequence generator, through the AD module on the oscilloscope display module, oil DA demodulation operation in the same block experiment board, the signal generation control LED lights off, and the modulated output signal displayed on the oscilloscope at the same time, and compared.)

说明：  资料是本人根据相关文献资料用vhdl语言编写的旋转机械鉴相信号倍频的程序，multifre1.vhd是倍频程序，multifre1.vwf是仿真波形文件，stp1.stp是虚拟逻辑分析仪signaltap文件。该倍频程序可以直接使用，可以设置倍频数，修改实体参数N即可。(According to the literature data is the information I have written in with vhdl Rotating Machinery Kam believe that the procedure multiplier number, multifre1.vhd is the multiplier process, multifre1.vwf is the simulation waveform files, stp1.stp a virtual logic analyzer signaltap file. The multiplier process can be used directly, you can set the multiplier number, modify the parameter N can be solid.)
