i2c代码（简单读写1字节数据）

dpim是光通信中使用的一种调制方式，这里提供的是它的环回代码，自己可以根据需要拆开了下载到两块板子上。(dpim is used in an optical modulation, here is its loop-back code, they can download needed two apart on the board.)

异步串行传输的verilog hdl 功能文件以及测试文件(The verilog hdl source and the testbench of asynchronous serial transmission )

2维4节点的UEL单元，嵌入UMAT，采用j2 mises屈服准则(2d4nodes uel elements, with umat codes, and j2 mises flow rule)

利用verilog实现乒乓双缓存代码，比异步FIFO更可靠地缓存。

使用Xilinx3S400开发的钢板检测算法中心化算法，通过测试。(a vhdl-program use Xilinx3S400)

vhdl测试程序，用于初雪者熟悉hdl的具体语法应用。比较简单了。(VHDL test procedure for the First Snow hdl who are familiar with the application of specific syntax. A relatively simple.)

Frame Control field
Retry:
Set in case of retransmission frame
More fragments:
Set when frame is followed by other fragment
Power Management
bit set when station go Power Save mode (PS)
More Data:
When set means that AP have more buffered data for a station in Power Save mode

基于单片机显示原理的IO和LED显示原理(Based on the principle of IO chip and LED display shows the principle)

用blockram实现移位寄存器，开发语言为verilog hdl(Shift register with blockram achieve the development language for the verilog hdl)

在zedboard开发板上采用vivado通过AXI进行DMA数据传输(Using vivado to transfer DMA data through AXI on zedboard development board)
