INTRODUCTION:

MOD-MP3-X is MP3 player module based on VS1053 Ogg
Vorbis/MP3/AAC/-WMA/MIDI audio decoder and an IMA ADPCM and user­loadable Ogg Vorbis encoder; supports VBR (variable bit rate) for MP3; Supports
streaming. It also employs an on-board STM32F103RBT6 CORTEX-M3 microcon­troller 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 VS1053 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 direct­ory listing, selecting of a file to play and playback and volume control.

STM32F103RBT6 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, 1200 mAh rechargeable battery and an on-board bat­tery charger.

BOARD FEATURES:

• On-board STM32F103RBT6 ARM 32-bit Cortex™-M3 microcontroller

• Based on VS1053 hardware decoder

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-20to10 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 2
development programmer/debugger from Microchip, because we don't offer a
suitable programmer, yet.

MOD-MP3-X-BAT (only):

POWER SUPPLY CIRCUIT:

MOD-MP3-X is typically power supplied with 5 VDC.

The programmed board power consumption is about 70 mA with all peripherals
enabled.

RESET CIRCUIT:

MOD-MP3-X reset circuit for VS1053 includes RC group - R7 (100kΩ) pull-

up and C12 (100nF), jumper MP3_RST, jumper VLS_RST, STM32F103RBT6 pin 43
(PA10/USART1_RX/TIM1_CH3) and VS1053 pin 3 (XRESET).

Note, that if VLS_RST jumper is closed, STM32F103RBT6 must not control

the VS1053 RESET, because VLS_RST is connected to ground.

MOD-MP3-X reset circuit for STM32F103RBT6 includes R36 (10kΩ) pull-

up, STM_RST jumper, SWD pin 10 and STM32F103RBT6 pin 7 (NRST).

Page 11

CLOCK CIRCUIT:

Quartz crystal Q1 (12.288 MHz) is connected to VS1053 pin 17 (XTALO)

and pin 18 (XTALI).

Quartz crystal Q2 (8 MHz) is connected to STM32F103RBT6 pin 5

(PD0/OSC_IN) and pin 6 (PD1/OSC_OUT).

JUMPER DESCRIPTION:

UEXT/BAT

When this jumper is shorted in position UEXT – the board is power suppied via

UEXT. When this jumper is shorted in position BAT – the board is power supplied via
BATTERY, USB or external power supply.
Default state is shorted in position BAT.

BOOT_E

When this jumper is closed, codec is able to boot firmware from EEPROM. This is for
standalone mode.
Default state is closed.

SA_E

This jumper connects SPI2_MOSI signal with SPI1_SCK signal.
Default state is closed.

DREQ_E

This jumper connects SPI1_SCK signal with DREQ signal.
Default state is closed.

MP3_RST/TXD and DREQ/RXD

When these jumpers are shorted in position MP3_RST and DREQ, the codec is
controlled direct via UEXT, without involving STM32F103RBT6. When these jumpers

are shorted in position TXD and RXD - via the UART interface of UEXT may be
submitted to STM32F103RBT6 commands to operate the codec.
Default states are shorted in positions MP3_RST and DREQ.

VLS_RST

When this jumper is closed, STM32F103RBT6 must not control the VS1053 RESET,
because VLS_RST jumper connects VS1053 pin 3 (XRESET) to ground
Default state is opened.

STM_RST

When this jumper is closed, STM32F103RBT6 is in reset.
Default state is closed.

R-T

This jumper connects RST signal with TRST signal.
Default state is opened.

BCD

This jumper connects the battery charger input and output. When is closed the battery
charger is disabled.
Default state is opened.

Jumpers description for changing EEPROM firmware:

–SA_E, BOOT_E and DREQ_E – opened

–STM_RST and VLS_RST – closed

–DREQ/RXD – closed in position DREQ

–MP3_RST/TXD – closed in position MP3_RST

–UEXT/BAT – closed in position BAT (position of this jumper depends on the source of

power that you will choose)

In this jumper position you can program on board EEPROM with the proper programmer
(for example PICkit2). Note that you have to make custom adapter cable between
EEPROM programmer and EEPGM connector. See EEPGM connector description below.

Commands for UEXT smart control mode:

In this mode you can use RXD and TXD signals of UEXT connector to communicate
between MOD-MP3-X and your computer. For this purpose, for example, you can use our
module MOD-USB-RS232, which creates a virtual COM Port. The COM Port setting are
9600bps 8N1.

You can also use other our boards with UEXT to connect with MOD-MP3-X.

It is the list of used commands:

Note: For the latest version visit our site: www.olimex.com/dev

- "L" - lists the current directory and return its contents, directories are marked with
a <DIR> tag

- "CDIRNAME <name>" - switch the current directory to <name>, name should be
up to 8 characters long

- "cnum <index>" - switch the current directory to the one with given <index>, as
displayed with the "L" command

- "." - returns to the parent directory, no higher than the root directory

Page 13

- "PSONGNAME <name>" - plays file in the current directory by its <name>,
<name> should be in 8+3 format and the only extension supported is ".MP3"

- "pnum <num>" - plays file in the current directory by its <index>, starting from 0.
<index> may be calculated by the sequence number displayed with the "L"
command minus the number of directories in the current directory.

- "OFF" - turns the codec chip OFF, may be executed at any time

- "ON" - turns the codec chip ON, may be executed at any time

These commands have meaning only when playback is started:

- "C - stop playing current file, returns "Stopped."

- "+" - increase volume by 0.5dB step, 0 refers to max volume value, 254 is minimal
value.

- "-" - decrease volume by 0.5dB step, 0 refers to max volume value, 254 is minimal
value.

- "p" - play/pause toggle during playback, returns "Paused"/"Playing" respectively.

- "?" - display information on supported commands.

*Note: All of the commands should be followed by a newline character ('\n' or
"\r\n")!

INPUT/OUTPUT:

Status Led (green) with name STAT1, connected to STM32F103RBT6 pin 2

(PC13/ANTI_TAMP).

Meaning of the status LED (STAT1) activity:

- When in mass storage mode the LED indicates SD card read/write activity.

- When playing a file in MP3 player mode LED is constantly ON.

- When playback is paused in MP3 player mode LED is blinking with 0.5Hz period.

Battery level status Led (yellow) with name STAT2, connected to STM32F103RBT6
pin 3 (PC14/OSC32_IN).

Battery level status LED (STAT2) activity:

- When powered by the battery the MOD-MP3-X indicated low battery level. If
voltage of the battery falls below 3.3V then the STAT2 LED starts to blink.

- If an external power source is connected, then battery starts charging. In this case
STAT2 LED is constantly lit while battery is charging and turns off when battery is
