摘要
电视遥控器使用的是专用集成发射芯片来实现遥控码的发射,不同公司的遥控芯片采用的遥控码格式不同,较普遍的有两种,一种是NEC标准,另一种是PHILIPS标准。有些公司摄像机的遥控器是不遵循任何标准的红外编码格式的,针对这种情况我们提出定时器捕获的方法,记录接收到的波形的过程即实现红外学习过程。
The special integrated emission chip is used to realize remote control code transmission in the telecontroller,but the remote control chips come from different companies which using the different format.There are two common types,one is the NEC standard,the other is the PHILIPS standard.However,some company's remote cameras do not follow any infrared encoding format standard.In view of this situation,the method of timer capture is proposed,which can record the received waveform and then achieves the process of infrared learning.
