学习使用contex-m3的stm32f103c6的程序库，LCD1602驱动程序。(Learn to use contex-m3 of stm32f103c6 the library, LCD1602 driver.)

这是一个智能电压表的实例，里面有完整的程序。这个电压表可以数字显示电压值的大小。 (This is the example of a table of a smart voltage, which has a complete program. This digital voltmeter shows the size of the voltage value.)

说明：  本课题对基于单片机的交通灯控制系统进行设计。以MCS-51系列单片机为控制核心，设计并制作交通灯控制系统，用于十字路口的车辆及行人的交通管理。东西南北四个路口具有左拐、右拐、直行及行人4种通行指示灯，并分别用计时器显示路口通行转换剩余时间，在特种车辆如119、120通过路口时，系统可自动转为特种车辆放行，其他车辆禁止通行状态。(Traffic light control system based on SCM (Single Chip Microcomputer) is designed in this paper. System requires that MCS-51 series SCM is used as CPU. Traffic light control system should be designed and made .There are four groups light which indicate to turn left, turn right, and go straight ahead and pedestrian access in east, west, north and south four directions. Timer shows traffic conversion remainder time. When special vehicles, such as 119,120 go through, the system can automatically allow special vehicles running and other vehicles is prohibited.)
