msp430g2553按键控制步进电机正反转，加速，启动停止(2553 Control Stepping Motor)

说明：  东西、南北两干道交于十字路口，各干道有一组红、绿、黄三个指示灯，指挥车辆和行人安全通行。南北方向为主干道，通行时间为35秒；东风方向为支干道，通行时间为25秒。通行时间最后3秒，绿灯灭，黄灯闪烁，黄灯闪烁完毕变更通行车道。通行时间由数字显示器显示，黄灯3秒闪烁不单另计时。 特殊情况控制通行方式控制，用按键开关K1控制主道通行，支道禁行，K2控制支道通行，主道禁行，特殊情况控制通行放行。 有紧急情况时用按键开关K3控制两道均为红灯。(The east-west and North-South arterial roads intersect at the intersection. Each arterial road has a group of red, green and yellow indicator lights to guide vehicles and pedestrians to pass safely. The north-south direction is the main road with a traffic time of 35 seconds; the east direction is the branch road with a traffic time of 25 seconds. At the last 3 seconds of the traffic time, the green light is off, the yellow light is flashing, and the yellow light is flashing to change the traffic lane. The traffic time is displayed by the digital display, and the yellow light flashes for 3 seconds, not only for another time. Under special circumstances, control the way of passage. Use key switch K1 to control the passage of main road, Branch Road, K2 to control the passage of branch road, main road and special circumstances to control the passage and release. In case of emergency, use key switch K3 to control two red lights.)
