INTRODUCTION:

MOD-MP3-X is MP3 player module based on VS1 53 Ogg

Vorbis/MP3/AAC/-WMA/MIDI audio decoder and an IMA ADPCM and user-

loadable Ogg Vorbis encoder; supports VBR (variable bit rate) for MP3; Supports

streaming. It also employs an on-board STM32F1 3RBT6 CORTEX-M3 microcon-

troller for smart control via UEXT.

MOD-MP3-X has three modes of operation:

–Standalone mode – compatible with the old revision MOD-MP3 player. In

this mode VS1 53 controls the playback of files written on a micro SD card inserted

in the board. The user is provided with controls on volume, sound effects, starting,

stopping and sequencing of files to play.

- UEXT playback mode – in this mode the board can be connected as slave device to

host microcontroller which streams data to the codec via SPI.

- UEXT smart control mode – in this mode the on-board microcontroller manages

playback of files written to the micro SD card. The microcontroller acts as a slave

device and accepts user commands via UART. Commands include SD card direct-

ory listing, selecting of a file to play and playback and volume control.

STM32F1 3RBT6 firmware has an extra - Mass storage device, through

which you can save MP3 files to the SD card.

Note that, while the board works as mass storage device, it can not work in

UEXT smart control mode. If you want to use the board in UEXT smart control

mode, then the USB must not be plugged in and the board has to be power supplied

via external power supply (PWR_JACK or BATTERY).

MOD-MP3-X ships in two variants – with and without battery. The battery

variant employs a Li-ion 3.7 V, 12 mAh rechargeable battery and an on-board bat-

tery charger.

ELECTROSTATIC WARNING:

The MOD-MP3-X board is shipped in protective anti-static packaging. The board

must not be subject to high electrostatic potentials. General practice for working

with static sensitive devices should be applied when working with this board.

BOARD USE REQUIREMENTS:

Cables: The cable you will need depends on the programmer/debugger you use. If

you use ARM-JTAG-EW, you will need USB A-B cable, for all types programmers

you will need ARM-JTAG-2 to1 adapter.

Hardware: Programmer/Debugger ARM-JTAG-EW , ARM-USB-OCD, ARM-

USB-TINY, ARM-USB-TINY-H , ARM-USB-OCD-H or other compatible

programming/debugging tool. For EEPROM programming you can use PICkit

development programmer/debugger from Microchip, because we don't offer a

suitable programmer, yet.
