这是用VHDL编写的FPGA与计算机进行串口通信的程序和一个LED程序...

说明：  基于RTL8211以太网芯片开发的以太网通信代码，使用Quartus编程，FPGA板子为开发者(Ethernet communication code based on rtl8211 Ethernet chip, using quartus programming, FPGA board for developers)

verilog描述的实用消抖电路，采用三个D触发器和一个JK触发器。使用emacs编写源文件，iverilog仿真通过，内有png仿真图像截屏(verilog description of the practical elimination shake circuit, using three D flip-flop and a JK flip-flop. Prepared source files using the emacs , iverilog simulation adopted, within the simulation images png screenshots)

VHDL实现led灯的动态扫描，主要对CLK进行分频-VHDL realization led lamp dynamic scan, the main points of the CLK to the frequency

说明：  在FPGA上实现CAN总线SPI接口通信，使用Verilog语言(Realize SPI interface communication of CAN bus on FPGA, using Verilog language)
