本文介绍了红外遥控的基本工作原理；红外发光二极管的特性；红外接收头详解；红外编码方式；单片机的应用；红外遥控程序流程图及通过对红外遥控器各按键发送中波形的分析可以识别码型，从而为软件解码提供依据。本文以实例介绍红外遥控器与单片机的硬件接口，并从原理出发给出软件解码的方法。这是一个可以直接引用的成功例子，同时也为各类红外遥控器在单片机控制产品中的开发应用提供了一个非常实用的参考。-This article describes the basic working principle of infrared remote control　infrared light-emitting diode characteristics　infrared receiver head Xiang Jie　infrared encoding　microcomputer applications　infrared remote control program flow diagram and through the various buttons on the infrared remote control to send the waveform analysis can identify code type, and thus provide a basis for software decoding. This paper describes examples of infrared remote control with the MCU hardware interface and software decoder is given starting from the principle of the method. This is an example of success can be directly referenced, but also for all kinds of infrared remote control products in the SCM in the development and application provides a very useful reference.
