摘　　要：本文介绍红外遥控器与单片机和单片机与电机的硬件接口,并从原理出发给出目前比较常用的几种软件解码方法.通过软件解码程序对红外遥控器发射的脉冲波形检测得出信号码,然后根据得到的不同信号来控制电机的转动,从而为软件解码提供依据.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.
