| Abstract: | The structure of BMP graph used in LED screen is analyzed, and a series of modes of data communication is compared. In fact, RS - 232C and RS - 485 communication modes are used at the same time. VB is used as programming language to write communication software. SCM is used to receive data and to control showing of LED screen. |
