当前时间送电脑同时显示,用RS232运用串口通信送数据给电脑，开中断计算时间，精确到秒。Keil C51开发环境，是一个整合很多技术的程序。 -current time to send the computer also showed that use RS232 serial data communications sent to the computer, open interrupted computing time, accurate to the second. Keil C51

MATLAB 程序,单片机采样后将数据由RS232上传到PC, 由MATLAB截获并画图, 实现示波器功能

这是USB转串口的驱动程序，对没有串口的电脑用处很大。-This is a USB-serial driver, there is no serial port on the computer use much.
