Make some noise with your next project! The MP3 Trigger board is built
to make it MP3 sound integration easier than ever. The board has 18
external trigger pins that will directly trigger pre-selected MP3
tracks, and a full-duplex serial control port that provides full
transport control, remote triggering for up to 256 tracks, and fast
real-time volume control. MP3s are stored on FAT16 formatted SDSC or
FAT32 formatted SDHC micro-SD flash memory cards. In addition,
optimized code now achieves 192Kbps stereo playback from a wider range
of cards than before.

The heart of the MP3 Trigger board is the Cypress PSoC CY8C29466-24SXI
microcontroller which serves up MP3 data to a VLSI VS1063 audio codec
IC. This version also supports an optional initialization file that
can be used to set the serial port baud rate as well as to reprogram
any of the 18 trigger inputs to alternate functions, including random
and sequential track selection, transport controls and even volume
up/down. Each conventional trigger can be set to either allow
immediate restarts, or to lock out restarts if audio is playing. Also,
a new trigger filename convention provides greater flexibility in
naming your MP3 tracks and makes file management easier.

There is also a "Quiet Mode" feature that can be enabled via the
serial control port. In this mode, the trigger inputs don't start
tracks directly, but instead produce a serial message indicating which
triggers were activated. A host microcontroller can thus monitor the
trigger inputs and then start any track or sequence of tracks via the
serial control port, making the triggers much more flexible.
