Design and Implementation of Infrared Remote Control Decoding Program Based on MCU

该文介绍基于士兰半导体芯片(SC6122)的红外发射遥控器,通过单片机解码程序,实现红外遥控信号的解码和接收。红外接收头与单片机特定的引脚连接,通过设置单片机定时计数器,采样来自红外接收头的高、低电平宽度解码遥控信号。该解码程序设计主要应用在LED数码显示控制和近距离红外遥控控制的电子产品中。

This paper introduces the infrared transmitting remote controller based on Shilan semiconductor chip(SC6122).The infrared remote control signal is decoded and received by the MCU decoding program.The infrared receiver head is connected with the specific pin of the MCU,and the high and low level width decoding remote control signals from the infrared receiver are sampled by setting a MCU timing counter.The decoding program is mainly applied to electronic products of LED digital display control and short-range infrared remote control.
