单片机用定时器产生38K载波，利用TC9012芯片的编码方式进行编码，每次发送一字节数据（学会了一字节，多字节也就会了），并由接收端解码加以显示！发射管用的是一般的红外管，接受用的是集成的红外接受器,通过测试，传输距离可达到5M左右！-Microcontroller timer generates 38K carrier, using TC9012 chip encoding encoding, each time you send one byte of data (a byte Society, will be a multi-byte), decoded by the receiver to display! Launch tubes to the general infrared tubes, with receiving the infrared receiver is integrated, tested, transmission distance up to about 5M!
