At the core of the MP3 Trigger board is the Cypress PSoC CY8C29466-24SXI microcontroller. This microcontroller delivers MP3 data to a VLSI VS1063 audio codec IC. This version of the board also supports an optional initialization file that can be used to set the serial port baud rate and reprogram any of the 18 trigger inputs to alternate functions. These functions include 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.
The MP3 Trigger board also features a "Quiet Mode". In this mode, the trigger inputs don't start tracks directly, but instead generate a serial message indicating which triggers were activated. This allows a host microcontroller to monitor the trigger inputs and then start any track or sequence of tracks via the serial control port, making the triggers much more flexible.
This version of the MP3 Trigger includes firmware that supports the use of an initialization file on the microSD card. This file can be used to change the serial baud rate and repurpose any of the 18 trigger inputs to alternate functions. In addition, a restart lockout option can be used to prevent any trigger from starting a track if audio is already playing. These features make the MP3 Trigger board highly adaptable for custom applications.
