Single-chip microcomputer as its control function is strong, high integration, low power consumption, low voltage, reliability and other characteristics, widely used and penetrated into all areas of our lives. This thesis is based on the present situation of electronic billboards, introduces a STC89C52 MCU as the core of wireless electronic billboard system design. Above the market at present there have been many kinds of electronic billboard,the design of the electronic billboards are mainly based on single chip microcomputer as control core, wireless way to send data, LED dot matrix screen display information of wireless electronic billboard, Wireless electronic billboard manufacture process were introduced in this paper the system design, chip selection, circuit principle and software design principle. With the development of the society, ordinary electronic billboard has been difficult to meet people now use requirements. The significance of this design mainly is to break the traditional way of cable transmission, to transmit data in wireless way greatly increases the electronic billboard use of the easy degree,improve th
