Abstract: simply fired on the infrared remote control, the principle of receiving system, is used as a remote control 89 C52 system decoder to receive a clever method, and a complete compilation of 51 of the code. Including the launching and receiving the principle of programming and the main program, sent the serial port procedures, receiving procedures, procedures regularly interrupted during the process, thereby completing the design of the main points of reference the idea of the process flow diagram, you can write applications software, Use of remote control codes and serial port checking function to prevent interference to other remote code, improve product reliability. Infrared remote control device with small size, low power consumption, strong function, and low cost.

Key words: 89 C52, infrared remote control, serial port
