Segun leo, usa 12 bit para codificar , que serian Adress y command.
The Samsung code consists of a start bit followed by a 12 Bit
manufacturers code and an 8 bit command code. The message
is always sent a minimum of twice.
A digital zero is represented by a ‘1‘ of 0.56 ms followed by
a ‘0‘ of 0.56 ms. A digital one is represented by a ‘1‘ of 0.56 ms
followed by a ‘0‘ of 1.69 ms. A continuous key press will cause
the message to be repeated every 60 mS. The carrier fre-
quency used for this code is 38 kHz.
There are no dedicated transmitter IC’s for the Samsung
system. A microcontroller is generally used to generate the
code e.g. the data sheet of the KS51840 from Samsung gives
an application for remote control use.
