3. If there is no requirement for one-to-one receiving function
of remote control, receiving program can be made to compare
the key code without comparing the address code.

Receive decoding programming
instructions
When the remote control does not send signal 433, the signal
foot of wireless receiving chip (DATA) is irregular miscellaneous
waveform, which is normal. When the remote control starts to
send signal 433, regular waveform will appear in the receiving
signal pin, and generally the receiving program detects the signal
with the interval time of 12MS for each sediment code, and the
decoding program enters to start decoding.
When writing the decoding program, we should pay
attention to the fact that the actual high level time is shorter than
the theoretical value, and the high level time of each remote
control will be different, so we set the high level time range as
large as possible.
