When a key is pressed for more than

When a key is pressed for more than 36ms, the oscillator activates the chip and transmits a set of 108ms coding pulses. The 108ms transmitting code consists of a guide code (9ms), a result code (4.5ms), a low-8-bit address code (9ms ~ 18ms), a high-8-bit address code (9ms ~ 18ms), an 8-bit data code (9ms ~ 18ms) and an inverse code of the 8-bit data (9ms ~ 18ms). If the key is pressed for more than 108ms and still hasn't been released, the next transmitted code (continuous code) will only consist of start code (9ms) and end code (2.25ms). (in fact, the action of human hands is very slow, even if you press the key quickly, it may be more than 108ms for the chip, so how to deal with the consecutive code is very important.) after pressing the key, the remote control periodically sends out the same 32-bit binary code, with a period of about 108ms. The duration of a set of codes varies with the number of binary "0" and "1", about 45-63ms.
