Design of intelligence remote control device with multimedia computer based on single chip microcontroller

In order to solve the phenomenon which can not be far away from the computer multimedia equipment to operate,this paper proposes a design of intelligence remote control device with multimedia computer based on STC89C51 single-chip microcomputer.In the design,combined with the infrared remote control device,infrared receiving circuit and serial port changed to USB module,it overcomes the inadequate problem effectively.The results show that,the device can automatically identify the remote control signal and decoding,can learn intelligently and custom button functions,Using a remote control aside with this device can break away from the shackles of cable computer,flexible use,convenient operation,cost effectiveness,can be widely used in classrooms,conference rooms,family,entertainment places and other occasions.
