This project is to create a small board that when
plugged into a PC USB port, will provide an interface to a DVSI digital voice
VOCODER chip. The idea is to be able to use a PC and soundcard and listen
and talk to a D-Star voice data stream over the internet. Other uses would
be to create a soundcard program that would implement the G4GUO HF digital voice
modem or just to use as a low bit rate vocoder for VOIP.
DVDongle Technical Reference Manual:
DVDongle Rev 2 Schematic
DVDongle ARM Source Code(2 projects, one for bootloader and one for the application):
Here is a little utility used for updating the DVDongle application flash memory. It takes a .hex file from the compiler and updates the DVDongle with it. Currently there is no new updates available.
A windows test application to record/playback compressed audio was written to test out the hardware and also demo the voice compression modes.
Here is the VC++6.0 source code and executable for AmbeTest program. This was just a program used to test the DVDongle hardware so is not a slick user application.
Currently, the DVDongle is being sold by HRO.
