DDS数字信号发生器

使用nios2点亮一个led灯，使用软件quartus13.0，开发板de2-115(nios2 led quartus13.0 de2-115)

拿verilog编写的som(自适应神经网络算法)，用于障碍物检测，基于FPGA可综合实验，已经在altera的cylcone上实现(Canal verilog prepared som (adaptive neural network algorithm) for obstacle detection. Based on FPGA synthesis experiments, in altera achieve the cylcone)

PWM调制流水灯的亮度，可以看到流水灯从亮到暗(PWM modulation)

采集外部设备的电压值，用FPGA内部自带的XADC(Collect the voltage value of the external device and use the internal XADC of the FPGA)

说明：  数字逻辑实验课第十二次作业，基于Verilog的Clock时钟(Clock based on Verilog)

VHDL上百实例 包括 ADDER LATCH FIPPER AND ETC..(VHDL hundreds of examples, including ADDER LATCH FIPPER AND ETC ..)

在FPGA开发板上用VHDL语言实现了贪吃蛇游戏，开发软件为quartus 2.这是详细的实验报告，包括源码(Snake game with VHDL FPGA development board, software development quartus 2 This is a detailed experimental report, including the source)

图像采集、存储控制verilog源代码(Image acquisition, storage, control of Verilog source code)

此代码为使用SPI 用于实现28335控制AD9959输出信号的频率、幅度(This code uses SPI The Frequency and Amplitude of AD9959 Output Signal Controlled by 28335)

带有电网电压反馈的单相PWM整流器反馈，输出的波形很好，适合初学者学习观摩(With power grid voltage feedback single-phase PWM rectifier feedback, the output waveform is very good, suitable for beginners learning view )
