cd4052用stm32来写的程序，，实现电子开关电路 (CD4052 uses STM32 to write the program, the electronic switch circuit)

研华数据采集的一个的demo文件，很好用，可以作为里程看，也可以作为现场采集数据的一个简单程序(Advantech data acquisition a demo file, very easy to use, you can see as mileage, can also be used as the data collected at the scene of a simple progra)

说明：  VB串口通讯实例 高精度电压表(24bit) VB源程序(VB serial communication example high precision voltage meter (24bit) VB source code)

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.)
