Quatus下用Verilog语言编写的双向交通灯控制系统，内含程序及波形图，注释详细，课程设计-Verilog language Quatus two-way traffic light control system, containing program and waveforms, detailed annotations, curriculum design

verilog 语言写的交通灯设计源代码，实现左转灯、红灯、绿灯、黄灯转换，并且提供手动控制按钮-verilog language source code for design of traffic lights, turn left to achieve lights, red light, green light, yellow light conversion, and provides manual control buttons

交通灯分为X组和Y组，每组包括了2位倒计时数码管和红黄绿三色LED信号灯（每组包括﹢、-两小组，显示内容一样），考虑到应用需求，要求芯片可通过I2C接口连接到上位机，以调节内部控制寄存器,此为Verilog代码，包含led、seg、timer等模块。-Traffic lights are divided into groups X and Y groups, each including two digital countdown yellow-green and red LED lights
