Application of Infrared Remote Devices Based on Single-chip Systems in Power Amplifiers
基于单片机系统的红外遥控器在功放中的应用

In this paper,the hardware joints between infrared remote devices and single-chip computers and those between single-chip computers and electric motors are presented.Several common software decoding methods and their principle are given.First,the software decoding program is used to detect the waveform of the pulse emitted by the infrared remote device so as to obtain signal codes.Then,the rotation of the electric motor is controlled according to the obtained different signals.Thus,the evidences are provided for the software decoding.
