这个程序利用89S51演奏生日快乐的歌曲 */

上车按键后开始计价。有实时时钟、单价、距离和总价钱显示。可以通过键盘修改单价（元/公里）和时间。有清除键用以清楚上次费用。利用LCD分别显示时间、单价、路程和费用。LED辅助显示说做操作。-Button on the bus after the valuation. Real-time clock, unit price, distance, and the total price display. You can modify the keyboard unit price (yuan/km) and time. There is the clear key to clear the last cost. Respectively, using LCD displays time, price, distance and cost. LED auxiliary display saying that operation.

本程序用于用单片机控制步进电机的转动。用单片机的某一个引脚实现控制，如果引脚电平为高则实现正转，反之为反转。所用单片机为日立系列h83664十六位单片机。本代码使用c语言实现，开发环境为日立系列单片机专用开发环境-This procedure for the use of single-chip stepper motor rotation control. With a pin MCU control, if the pin level is higher then realize to the contrary, for the inversion. Used in single-chip for Hitachi Series 16 Singlechip h83664. This code uses the c language, development environment for the Hitachi series of single-chip dedicated development environment
