drs232 - Horus SSTV reception using the codec2 library.
drs232 usage: InputOneBitPerChar OutputPacket [-v[v]]
Looks for a unique word in series of bits. When found, deframes a RS232 encoded frame of bytes. Used for high bit rate Horus SSTV reception.
Frame format:
16 bytes 0x55 - 0xabcdef01 UW - 256 bytes of payload - 2 bytes CRC
Each byte is encoded as a 10 bit RS232 serial word:
0 LSB .... MSB 1
The first argument, InputOneBitPerChar is the file name of a file with Horus encoded bits. If "-" is given the input is taken from stdin.
The second argument, OutputPackets is the file name of a file to be created with modem sample data. If "-" is given the output is sent to stdout.
The optional third argument, [-v] [-vv] set the verbosity of the output.
