[assembly language] control-systerm-ASM DL : 0: 基于AT89C51的交通控制系统，以ASM为开发环境。 1.AB方向亮绿灯60s，然后黄灯闪烁3次，每次一秒（亮灭各40ms），红灯40s，同时CD方向红灯65s，绿灯35s，黄灯闪烁3s 2.各路灯用LED模拟显示，同时用七段数码管显示两路的倒计时时间 3.利用键盘可修改灯亮时间 4.PC机设置灯亮时间，利用PC与单片机串口通信实现 -AT89C51-based traffic control system to ASM for the development environment. 1.AB Directional Brightness green 60s, and then the yellow light flashes three times, each time one second (light off each 40ms), red 40s, while the direction of the red CD 65s, green 35s, flashing yellow 3s 2. Various street lights with LED analog display, but with two seven-segment digital display countdown time 3 can be modified using the keyboard lights lit time 4.PC time machine settings using PC serial communication with the MCU
