本程序是基于STC系列单片机的2012年中职教师培训教程，实现了DS18B20的温度实时采集，数码管显示，定时器控制的跑马灯，按键实现功能切换，温度上下限设置，高低温报警，继电器控制，步进电机控制等功能。可供初学者学习使用，给有一定单片机基础的朋友提供参考。-This procedure is based on the STC Series MCU 2012 in-service teachers training course, the DS18B20 temperature acquisition in real-time, digital display, timer control Marquee, key switch function, set the lower limit on the temperature, high and low temperature alarm, following electrical control, stepper motor control, and other functions. For beginners to learn to use, and provide a reference to a certain microcontroller-based friends.
