Abstract
Now the society is a high automated society, all kinds of equipment can link to the computer on-line, but the simple automated on-line way is to use serial communication. Serial communication existence time is already not short, along with the technical development, it not only has not been substituted, its application scope is more broadly. The serial communication take one kind nimble, convenient, reliable mailing address, has the connection simply, and the transmitting range is long and so on the merit. In the industry monitoring, the data acquisition and the real-time control system obtained the widespread application. In these applications is especially most common by the byte correspondence.
This graduation project topic is "the design and realization of data communication Serial communication ", it is designed by C++ Builder mainly . The computer is connected through the RS-232 main-line and the liquidcrystal screen, then the liquidcrystal screen or the range selector control the LED display monitor again. It is designed by C++Builder, compile the computer connect the singlechip with RS-232,and made it to storage, transmit and show 3、4、8、16 massages.So it is realized to send and accept the data.
Key words: Serial communication ，RS232 C++Builder，LED display monitor.
