@:
@: DVB-S2 packet to short frame converter for ARM
@: Accepts 188 byte packets and produces DVB-S2 frames to send to an IQ modulator
@: Supports FEC 1/4 or 3/4 only
@: Supports rolloff 0.20, 0.25, 0.35
@: For QPSK modulation only
@:
@: For FEC 3/4,
@: The optimum packet processing time is 25us on an RPI0 and 15us on an RPI3
@: The equivalent frame processing time is 195us on an RPI0 and 115us on an RPI3
@:
@: Parts derived from DATV-Express and RPiDATV
@: Thanks to G4GUO and F5OEO for their help

@: It has no warranty of fitness for any purpose.
@: Generation of a DVB-S2 transport stream may require a licence.

@:
@: When setting the mode, FEC 3/4 and rolloff 0.35 are selected as defaults

@: The supplied buffer address should point to 8832 bytes on a 32 byte boundary (not checked)
@: This area is used to cycle around 4 x 2208 byte output buffers

@: The effiency value is used to determine the required bit rate of the 188 byte TS
