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.)

使用STM32F4+usb3300实现虚拟示波器,支持使用外部ADC模式，也就是使用AD9280芯片，最大采样率可达30MSPS.(STM32F4+usb3300 implementation of the virtual oscilloscope, support the use of external ADC mode, that is, the use of AD9280 chip, the maximum sampling rate of up to 30MSPS )

通过RS485端口不停地发送数据0xaa用示波器观察RS485端口A、B信号线上的波形或者用RS485接收器接收发送的字符。(Through the RS485 port to send data continuously 0xaa observed with an oscilloscope RS485 ports A, B signal waveforms or use the RS485 line receiver sends characters.)
