说明：  红外接收解码 工程说明 本案例实现了编码格式为“引导码+地址码+数据码+数据反码”的红外发送数据进行接收和解码，并将收到的数据显示到七段译码器上。 案例补充说明 在实际的产品设计或业余电子制作中，编码芯片并一定能完成要求的功能，这时就需要了解所使用的编码芯片到底是如何编码的。只有知道编码方式，我们才可以使用单片机或数字电路去定制解码方案。
(Infrared receiving and decoding Engineering description In this case the encoding format for infrared sending data to guide the code and address code + data + code data complement "is received and decoded, and display the received data to the seven segment decoder. Case Supplement In the actual product design or amateur electronic production, the coding chip must be able to complete the required function, then it is necessary to understand how the encoded chip is encoded. Only when we know the encoding method, can we use the microcontroller or digital circuit to customize the decoding scheme.)
