Verilog DDS发生器的实现

stepper motor vhdl pin assignments and code

基于VHDl的2FSK调制！用的是altera的quartus11软件(Based on VHDl the 2FSK modulation)

VHDL TESTBENCH书写规范，对学习FPGA的同学很有帮助，掌握仿真语言书写规范。(VHDL TESTBENCH description of the norms, the students learn FPGA helpful, master the language of simulation techniques)

用逻辑实现iic协议，其中fpga端作为从设备，接收主设备发送过来的信号，并解析。由于是是作为从设备，因此，也不需要发送对端的IIC地址，对外就是SDA和SCL这2根信号线

VGA显示FPGA实现的VHDL语言的贪吃蛇游戏设计 本设计分为6个模块主要是扫描模块 VGA现实和控制模块 游戏设计的模块 电源模块等 用QUARTUS2仿真运行(VGA display FPGA VHDL language to realize the Snake game design The design is divided into six modules mainly scanning module VGA module power module and control module reality game design, etc. Simulation run with QUARTUS2)

verilog编写的RTC（实时时钟）包含APB总线接口、时钟计时部分等(verilog prepared by the RTC (real time clock) contains APB bus interface, clock time some other)

bpsk qpsk 16qam 64qam的constellation(bpsk qpsk 16qam 64qam constellation)

本人上网下载下来并调试过的，完全实现NIOS 点亮LCD_Panel，附件是驱动部分。

DE2-115开发板TV摄像头成像程序，源码亲测可用，可加入边缘算法成像，实时显示轮廓，速度流畅(The DE2-115 development board TV camera imaging procedures, the pro-test in the source can be added to the edge algorithms imaging, real-time display contours, fast-paced)

该代码实现了对SD 卡的读写操作，是一个较好的范例。(The code achieves access reading SD CARD based on DE-2，It is a good example。)
