友晶 altera DE2开发板中文用户手册，对DE2开发板的完整介绍。(DE2 development board Chinese user manual, a complete description of the DE2 board.)

说明：  LDPC的编解码的实现，适合初学者学习，大家可以多交流(The implementation of LDPC Encoding and decoding is suitable for beginners to learn)

主控cc2530通过debug接口对目标cc2530进行程序烧写，使用DMA进行数据传输，已调试通过。(Master cc2530 through the debug interface for writing the program to target cc2530, using the DMA data transfer, has been work successful.)

实现线性反馈移位寄存器的verilog实现(lfsr use verilog for the zip)

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)

有符号数的完整讲义和例子Verilog 2001(Signed Arithmetic in Verilog 2001, paper with examples)

通过MATLAB产生单脉冲信号的数据，存储下来作为verilog代码实现的DDS的数据源，用于验证DA数据的ddio的调试是否有问题。(The data of monopulse signal generated by MATLAB is stored as the data source of DDS implemented by Verilog code to verify whether the ddio debugging of DA data is problematic.)

说明：  用verilog编辑的中值滤波器！语言旁表有注释方便理解！(Using Verilog editor median filter! Language beside the table annotated to facilitate understanding!)

基于verilog的2FSK调制程序，simulink仿真通过(2FSK modulation program based on Verilog, Simulink simulation passed)

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