对用开发板上开关产生的信息做汉明编码并通过串口发送至电脑(The Hamming code is generated from the switch on the development board and sent to the computer through the serial port.)

I2C 的ip核与testbench，用verilog写的，包括master，slave reg

基于VHDL的数字频率计的设计.pdf 基于VHDL的频率计设计 很好用的 希望要用的同志来下载 (基于VHDL的频率计设计 很好用的 希望要用的同志来下载 )

说明：  对delta sigma进行设计，实现delta sigma ADC的设计(this is use for delta sigma adc ,and design and achieve adc)

用FPGA实现 VGA显示的图像显示控制器设计 用VHDL实现 硬件实现是屏幕上面出现彩色条纹(VGA display with FPGA image display controller design Using VHDL hardware implementation is colored stripes appear above the screen)

VHDL Handbook by HARDI Electronics AB

说明：  实现数字频率合成实验，加载数据ram,形成波形(The experiment of digital frequency synthesis is realized, and the data RAM is loaded to form the waveform)

键盘计算器，可实现加减乘数运算 基于fpga nios2(Keyboard, calculator, addition and subtraction can be realized based on fpga nios2 multiplier operator)

本模块适合所有红外接收端，使用时请注意修改地址码，要接收的就是识别用户码，代码里有标注，谢谢大家的支持！
