Description: 433m/315m wireless decode data, based on self-made PT2272 chip. Encoded signal emitted by the chip PT2262: address code, data code, to form a complete synchronization code codeword, decoder chip PT2272 received signal, which address code after two comparison check, VT pin only output high, At the same time the corresponding data feet high output, if the sender has been holding down the button will continuously transmit coded chip. When the transmitter is no button is pressed, PT2262 no power, its 17 feet low, so the high-frequency transmitter circuit 315MHz does not work, when a key is pressed, PT2262 electrical work, its 17-pin output modulated serial data signal, when 17 feet high during 315MHz frequency transmitter circuit start-up and launch a high-frequency signal amplitude, when 17 feet during the flat 315MHz frequency transmitter circuit stops oscillating, so high transmitter frequency control circuit is completely closed PT2262 digital signal output of 17 feet, and thus high-fr
