ABSTRACT
How to get rid of the trouble and inconvenience of the complicated cable, and establish a comfortable, convenient and reliable wireless work environment has become an urgent desire. So, the wireless data transmission technology which greatly different from the traditional cable transmission, has come out. Short-range wireless data communication is advantage in low cost, scalability, less restricted conditions, and easy access to the characteristics of flexibility. So it has a broad application in consumer electronics products, wireless alarm and security systems, wireless sensor networks and many other areas.
As infrared transmission of information has the advantage of simple control, high reliability transmission characteristics，the design pose an easy-to-read data coding schemes based on minicomputer as the basis for achieving a simple infrared data communications systems. Then it goes on to verify and compare each modules of this circuit. The system’s main purpose is to achieve the low wrong code rate and high-speed data transmission. This paper introduces the Infrared Data Communication and the basic principles of data encoding and decoding, put the design of transmitting and receiving into two modules, given the specific hardware and software.
Key words：MCU; LED display; Infrared communication; synchronized serial communications
