摘要
本文介绍了利用双音多频(DTMF) 编译芯片S2559 和SC8870 通过红外线遥控方式发送键码给控制对象和单片机( MCV) 同时输入指令实现遥控控制的方法及该电路的设计原理和电路组成。
In this paper,two encoding chips S2599 and SC8870 with DTMF are intvodaced.They can transnit encoding signs and realice maltiple componets control by use of infrared remote control.The principle and the design of the circuit are given.
