TM1652
TM1652 是一款LED（发光二极管、数码管、点阵屏）驱动控制专用芯片，内部集成了数字通讯电路、
解码电路、数据锁存器、震荡器、LED驱动电路。通讯方式采用异步串口通信（UART）协议，因芯片只
接收单片机发来的数据，仅需要单片机的一个TX端口发送数据给芯片即可，实现单线通讯；在显示驱动
方面，芯片采用动态扫描方式，两种显示模式可选，8级段驱动电流可调，16级位占空比可调；TM1652
内置消隐处理优化电路。(TM1652 is an LED (light-emitting diode, LED, dot-matrix screen) driver control ASIC, integrated digital communications circuits,
Decoding circuit, data latch, oscillator, LED driver circuit. Communication using asynchronous serial communication (UART) protocol, because the chip only
MCU receives data sent only need a microcontroller TX port to send data to the chip can achieve single-wire communication the display driver
Aspects, chip dynamic scan mode, two display modes, 8 segment drive current is adjustable, 16-bit adjustable duty cycle TM1652
Built-in blanking processing optimization circuit.)

交通灯控制
包含proteus仿真文件及c语言程序，在开发板上进行过运行。利用双色LED显示电路，和四位静态数码管显示电路模拟十字路口交通信号灯。4位LED数码管显示时间，双色LED灯显示红绿灯状态。熟悉交通信号灯控制逻辑。设计一个十字路口的交通灯控制电路，要求南北方向和东西方向两个交叉路口的车辆交替运行。每次绿灯变红灯时,要求黄灯先亮3S,才能变换运行车辆。东西方向、南北方向车道除了有红、黄、绿灯指示外，每一种灯亮的时间都用数码管显示器进行显示（采用倒计时的方法）。考虑到特殊车辆情况，设置紧急转换开头。(It contains proteus simulation file and C language program. It has been run on the development board. Two-color LED display circuit and four-bit static digital tube display circuit are used to simulate traffic lights at intersections. Four-bit LED digital tube display time, two-color LED lights show the status of traffic lights. Familiar with traffic signal control logic. Design a traffic light control circuit at the intersection, which requires the vehicles running alternately in the north-south direction and the East-West direction. Every time the green light turns red, the yellow light is required to turn on 3S before changing the running vehicle. In addition to the red, yellow and green lights in the east-west and North-South lanes, the time of each kind of light is displayed by digital tube display (countdown method). Considering the special vehicle situation, set up the emergency switch start.)
