Method getCodeWordB

Sming/Libraries/RCSwitch/RCSwitch.cpp:280–310

* Returns a char[13], representing the code word to be sent. * A code word consists of 9 address bits, 3 data bits and one sync bit but * in our case only the first 8 address bits and the last 2 data bits were used. * A code bit can have 4 different states: "F" (floating), "0" (low), "1" (high), "S" (sync bit) * * +-----------------------------+-----------------------------+----------+-------

 * @return char[13]
