Operation
460800 is the baud rate of the PC connection
-ppt sets the HDK to use the PPT Interface of the AMBE-3000™ Vocoder chip
or
-uart sets the HDK to use the UART Interface of the AMBE-3000™ Vocoder chip
If neither –ppt or –uart is specified the PPT interface is used by default.
-r 39 is the rate index of the bit rate the file is to be decoded at 3600bps.
-dec decodes the previously encoded file and saves it to a file
dvsi36tst.bit is the name of the encoded file to be decoded
dvsi36tst.pcm is the name of the file to be saved
To validate that the file was decoded correctly simply compare the created file dvsi36tst.pcm with
the similar file dvsi36.pcm included on the HDK CD.
In the HDK directory use the following DOS command.
C:\ Command Prompt
- ’ X
cmp dvsi36.pcm dvsi36tst.pcm
