Email: catalex_inc@163.com Name: Serial MP3 Player manual Version: v1.0 Date: Aug 22, 2014 ©CATALEX 1 / 10 Email: catalex_inc@163.com 1 Description The module is a kind of simple MP3 player device which is based on a high-quality MP3 audio chip---YX5300. It can support 8k Hz ~ 48k Hz sampling frequency MP3 and WAV file formats. There is a TF card socket on board, so you can plug the micro SD card that stores audio files. MCU can control the MP3 playback state by sending commands to the module via UART port, such as switch songs, change the volume and play mode and so on. You can also debug the module via USB to UART module. It is compatible with Arduino / AVR / ARM / PIC. Features： 1. Support sampling frequency (kHz): 8 / 11.025 / 12 / 16 / 22.05 / 24 / 32 / 44.1 / 48 2. High quality 3. Support file format: MP3 / WAV 4.

UART TTL serial control playback mode, baud rate is 9600bps Power supply can be 3.2 ~ 5.2VDC Control logic interface can be 3.3V / 5V TTL Compatible with Arduino UNO / Leonardo / Mega2560 / DUE 2 / 10 Email: catalex_inc@163.com 2 Specification Item Min Typical Max Unit Power Supply(VCC) 3.2 5 5.2 VDC Current（@VCC=5V） / / 200 mA Logic interface 3.3V / 5V TTL / Micro SD card(<=2G); Supported Card Type / Mirco SDHC card(<=32G) File system format Fat16 / Fat32 / Uart baud rate 9600 bps Dimensions 49X24X8.5 mm Net Weight 5 g 3 / 10 Email: catalex_inc@163.com 3 Interface Control interface: It is UART TTL interface. A total of four pins (GND, VCC, TX, RX), GND to ground, VCC is the power supply, TX is the TX pin of the MP3 chip, RX is the RX pin of the MP3 chip. TF card socket: The micro sd card can be plugged in it. Playbck indicator: Green light. If it is ready to play or it is paused, it keeps lighting. If playing, it blinks. Headphone jack: It can be connected with the headphone or external amplifier. Mounting holes: 4 screw mounting holes whose diameter is 2.2mm, so that the module is easy to install, easy to combine with other modules. 4 / 10 Email: catalex_inc@163.com 4 Usage 4.1 About the commands 4.1.1 Asynchronous serial port control play mode: Command bytes: $S VER Len CMD Feedback data $O Mark Byte Byte description $S 0x7E Every command should start with $(0x7E) VER 0xFF Version information Len 0xxx The number of bytes of the command without starting byte and ending byte CMD 0xxx Such as PLAY and PAUSE and so on Feedback 0xxx 0x00 = not feedback, 0x01 = feedback data $O The length of the data is not limit and usually it has two bytes 0xEF Ending byte of the command 4.1.2 Commonly Command bytes Descriptions: Command Command bytes without checksum(HEX) [Next Song] 7E FF 06 01 00 00 00 EF [Previous Song] 7E FF 06 02 00 00 00 EF Remark 7E FF 06 03 00 00 01 EF Play the first song 7E FF 06 03 00 00 02 EF Play the second song [Volume up] 7E FF 06 04 00 00 00 EF Volume increased one [Volume down] 7E FF 06 05 00 00 00 EF Volume decrease one [Set volume] 7E FF 06 06 00 00 1E EF Set the volume to 30 (0x1E is 30) [Single cycle play] 7E FF 06 08 00 00 01 EF Single cycle play the first song [Select device] 7E FF 06 09 00 00 02 EF Select storage device to TF card [Sleep mode] 7E FF 06 0A 00 00 00 EF Chip enters sleep mode [Wake up] 7E FF 06 0B 00 00 00 EF Chip wakes up [Reset] 7E FF 06 0C 00 00 00 EF Chip reset [Play] 7E FF 06 0D 00 00 00 EF Resume playback [Pause] 7E FF 06 0E 00 00 00 EF Playback is paused 7E FF 06 0F 00 01 01 EF Play the song with the directory: /01/001xxx.mp3 7E FF 06 0F 00 01 02 EF Play the song with the directory: /01/002xxx.mp3 [Play with index] [Play with folder and file name] [Stop play] 7E FF 06 16 00 00 00 EF [Cycle play with folder name] 7E FF 06 17 00 00 01 EF [Shuffle Play] 7E FF 06 18 00 00 00 EF [Set single cycle play] 7E FF 06 19 00 00 00 EF 5 / 10 01 folder cycle play Start up single cycle play Email: catalex_inc@163.com [Set DAC] [Group play with indexes] [Play with volume] 7E FF 06 19 00 00 01 EF Close single cycle play 7E FF 06 1A 00 00 00 EF Start up DAC output 7E FF 06 1A 00 00 01 EF DAC no output 7E FF 09 21 00 05 01 02 03 04 EF Play 5 songs in the order of the song index: 05, 01, 02, 03,04 7E FF 0C 21 00 05 01 02 03 04 06 07 08 EF Play 8 songs in the order of the song index: 05, 01, 02, 03,04, 06, 07, 08 7E FF 06 22 00 1E 01 EF Set the volume to 30 (0x1E is 30) and play the first song 7E FF 06 22 00 0F 02 EF Set the volume to 15(0x0f is 15) and play the second song 4.2 Use USB to Uart TTL module (1) You need a USB to Uart TTL module (such as USB/Serial Adapter) to connect Serial MP3 Player to PC. The hardware installation as show below: (2) After the connection is completed, open the sscom32 serial tool that you can down load from catalex net disk to send commands. About the specific commands, please refer to 4.1.1 part. (3) Click the EXT button and then you can manage the commands to be sent. 6 / 10 Email: catalex_inc@163.com (3) Baud rate should be 9600. Tick HEX and HexData so that the command can be received by the Serial MP3 Player and you can see the feedback information (refer to the file YX5300-24SS Datasheet V1.0.pdf) in the blank of the window. Before sending commands, you should select the [ComNum] and click [Open Com]. 7 / 10 Email: catalex_inc@163.com (4) Make sure your micro sd card is formatted as FAT16 or FAT32 and there is some songs in it. May be you should creat folder “01” and “02”, and put some songs with the name 001xxx.mp3 / 002xxx.mp3 / 003xxx.mp3 in the two folder. Some commands need them. (5) After power up, you should send the command [Select device] first. Serial MP3 Player only supports micro sd card, so you should send “ 7E FF 06 09 00 00 02 EF ”. Then you can send the command [Play with index] to play some song. You can send the command [Set volume] to set the volume(0 ~ 30 class). More operations ? Please refer to 4.1.1 part. 4.3 Use Arduino UNO R3 4.3.1 Project1: Simple test for the player. Step1: Material preparation 1x Arduino UNO R3 1x USB Cable 1x Serial MP3 Player 1x Base Shield 4x Female to Female Dupont cables Step2: Hardware install (1)Plug the Base Shield which is just the I/O expansion board to Arduino UNO R3. (2)Connect the modules and Base Shield with the cables: Serial MP3 Player Wire Base Shield GND <---> GND VCC <---> 5V TX <---> D5 RX <---> D6 (3)Make sure your micro sd card is formatted as FAT16 or FAT32 and there is some songs in it. May be you should creat folder “01” and “02”, and put some songs with the name 001xxx.mp3 / 002xxx.mp3 / 003xxx.mp3 in the two folder. Some commands need them. Plug the micro sd card into the TF card socket on the Serial MP3 Player, and then plug the headphone. 8 / 10 Email: catalex_inc@163.com Step3: Power on Use the USB cable to connect the Arduino UNO R3 and PC. Step4: Upload the demo code Download the demo code (SerialMP3PlayerDemoforArduino-1.0.zip), and unzip it to your code project folder such as ../Arduino-1.0/MyProject. And then upload the code to your arduino UNO R3. Step5: Enjoy yourself Push the reset button on the Base Shield to play the first song in the micro sd card. Step6: Power off Unplug USB cable. 4.3.2 Project2: Use some modules to control the player. Enjoy! Step1: Material preparation 1x Arduino UNO R3 1x USB Cable 1x Serial MP3 Player 1x Base Shield 1x Touch Sensor 1x Rotary Angle Sensor 10x Female to Female Dupont cables Step2: Hardware install (1)Plug the Base Shield which is just the I/O expansion board to Arduino UNO R3. (2)Connect the modules and Base Shield with the cables: Wire Base Shield GND <---> GND VCC <---> 5V TX <---> D5 RX <---> D6 Touch Sensor Wire Base Shield GND <---> GND VCC <---> 5V SIG <---> D2 Rotary Angle Sensor Wire Base Shield GND <---> GND VCC <---> 5V SIG <---> A0 9 / 10 Email: catalex_inc@163.com (3)Make sure your micro sd card is formatted as FAT16 or FAT32 and there is some songs in it. May be you should creat folder “01” and “02”, and put some songs with the name 001xxx.mp3 / 002xxx.mp3 / 003xxx.mp3 in the two folder. Some commands need them. Plug the micro sd card into the TF card socket on the Serial MP3 Player, and then plug the headphone. Step3: Power on Use the USB cable to connect the Arduino UNO R3 and PC. Step4: Upload the demo code. If you have download in Project1, skip this step. Download the demo code (SerialMP3PlayerDemoforArduino-1.0.zip), and unzip it to your code project folder such as ../Arduino-1.0/MyProject. And then upload the code to your arduino UNO R3. Step5: Enjoy yourself Push the reset button on the Base Shield. In the process that the Rotation Angle Sensor is rotated from the 'Min' side to the 'Max' side, the volume is gradually greater. If you touch the Touch Sensor,it will play or pause. About more specific commands, please refer to 4.1.1 part. Step6: Power off Unplug USB cable. 5 Part List 1x Serial MP3 Player Module Documents download link: http://pan.baidu.com/s/1hqilpB2 10 / 10
