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 (each including+,- two groups, as the display contents), taking into account the needs of the application, the chip may be required It is connected to the host computer via the I2C interface, to adjust the internal control registers of this Verilog code, comprising led, seg, timer modules.
