[Robotgroup] Vinculum VMusic player: Nice writeup

[Gray Mack]

Yes it does work, and they continue to improve the
firmware and fix the glitches.
It does suffer some of the same problems of the Rogue
uMP3 being based around a VS1003 mp3 decoder. A slight
pause before the audio file starts, unable to query
the exact location in the playback (only has seconds
not 100th seconds) and sound glitching whenever you
issue a command like volume change. You can't jump to
a specific place in a song or pause a song, play a
sound effect, then go back to the song, but you can
use two of them and mix the analog outputs for
music+sound effects.

It uses a usb thumb drive instead of a SD card.

You can also use it to get serial access to thumb
drives or other usb devices (It is a usb host chip)
So something like reading a usb joystick, mouse, or
GPS may be possible, but a webcam-probably not (I
could never find enough info on webcam protocol to
accomplish this).

I asked the developers to add a few more features,
like direct access to the VS1003 which can do real
time midi synthesis and frequency analysis, but they
have not, yet, and I never got around to hacking the
data line.
