| Abstract: | Using AT89S52 Single Chip Micyoco(SCM) as the central control of the system and infrared ray remote as keyboard interface and based on PS/2 protocol,scan codes are sent to the computer and consequently communication is established.This interface mode can not only reduce hardware requirements for the Single Chip Micyoco(SCM),but also can manipulate computer wirelessly within some distance.As a result,this design will find wide applications in industrial controls as well as in multimedia teaching. |
