说明：  交通灯的控制，分主干道和从路交通灯，主路优先，正常情况下，绿灯60s，红灯30S，黄灯5S(Traffic light control)

实现4种常见波形正弦、三角、锯齿、方波（A、B）的频率、幅度可控输出（方波 --A的占空比也是可控的），可以存储任意波形特征数据并能重现该波形，还可完成 --各种波形的线形叠加输出。 (Achieve the four kinds of common sine wave, triangle, sawtooth, square wave (A, B) the frequency and amplitude controlled output (square wave- A duty cycle is controlled), can store arbitrary waveform feature data and can to reproduce the waveform, it can perform- all kinds of linear superposition of the output waveform.)
