Packet Mode Encode/Decode File Command Example:
C:\ Command Prompt
- ’ X
hdkcom.exe –port COM4 460800 –uart or –ppt –r <rate index or rate words in
hex> -encdec <input filename> <output filename>
where
COM4 is the COM port on the PC that the HDK will communicate on
460800 is the baud rate of the PC connection
-r is the rate index of the bit rate the file is to be decoded at. See Table 23 Standard Rate Table
for AMBE-3000™. To use rate words to set the rate – the format must be six words in hex
separated by a space as shown in the following example:
-r 0x0460 0x0986 0x0000 0x0000 0x0000 0x5660
-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.
–encdec the HDK encodes the following input PCM file then decodes it and saves it to a PCM file
with the following output file name
<input filename> is the name of the file to be encoded/decoded
<output filename> is the name of the file to be saved
