摘要
采用一体化红外接收器HS0038B设计并实现了学习型红外遥控器,对遥控器的编码信号进行采样,记录编码波形,对高低电平进行脉宽计数,转换成脉宽编码,从而实现"学习"功能,发送时根据存储的脉宽编码恢复出编码信号的脉冲波形。该方案与具体遥控器的编码协议无关,提高了通用性。
A learning infrared remote control is designed and implemented using HS0038B which is a kind of infrared receiver.After sampling of coding signal,pulse waveform is recorded.Pulse width of high and low level is counted,and pulse width code is stored.Consequently,learning function is implemented.When sending control signal, pulse waveform of code signal is recovered according to stored pulse width code.The method is independent of coding protocol of specific remote control,and therefore universality is improved greatly.
