用VHDL写的交通灯控制源码，原创，希望对大家有所帮助

这是一个用VHDL语言编写的并口转串口程序，在altera开发系统下验证通过，运用于开发板与计算机之间的通信，源程序可以提供参考-This is a use of the VHDL language Parallel to Serial procedures, In altera development system under test passed, the development of applied between the panels and computer communications, can provide a reference source

to learn bout development of vhdl code

RS编码器在fpga上的实现，用的modelsim开发环境(RS encoder in the realization of the fpga, development environment used in modelsim)

说明：  一个走马灯的程序,可以按照要求一个一个往后面按顺序点亮(A program for the lantern can be lit one by one according to the requirements.)
