Detailed Description

Create frequency-shift-keyed samples for encoding synchronization signals.

An array of data is given to a FSK object using set_data(), and on calling get() this data will be returned in a the D-Cinema FSK "format", sample by sample, starting with the MSB of the first byte in the data array.
