基于单片机的火车测速系统源程序。利用单片机STC89C52系统实现列车行驶速度测量转换和LCD液晶显示。同时实现列车行驶方向判断和指示，键盘设定速度上下限，当速度超限时给出超速报警提示。(Train speed system based on single chip source, using SCM STC89C52 trains speed measurement system to achieve conversion and LCD display. While achieving the train driving directions judgment and instructions, keyboard set speed limit, when the speed exceeds the limit given speeding alarm.)

飞思卡尔８位单片机的ＳＰＩ通信操作，简单明了，可以直接使用，也可以移植使用！(Freescale 8-bit microcontroller SPI communication operations, straightforward, and can be used directly, and also can be ported to use!)

说明：  STM32F103_硬件SPI控制LCD例程(STM32F103_Hardware SPI Control LCD Routine)

说明：  首先它能显示环境的温度并能设置上下限阀值，这是最基本的功能，系统上电的时候显示的是当前环境温度和设定的温度阀值，我们可以通过按键来修改温度上下限阀值。(First of all, it can display the environment temperature and set the upper and lower limit threshold, which is the most basic function. When the system is powered on, it displays the current environment temperature and the set temperature threshold. We can modify the upper and lower limit threshold by pressing the key.)
