DFRduino_Player_module(.NET_Gadgeteer_Compatible)_(SKU_TOY0008) - jimaobian/DFRobotWiki GitHub Wiki
Introduction
This DFRduino Player module is a MP3 module compatible with .net gadeteer.The Player is able to play MP3/WAV/Midi sound tracks on SD card. It supports two kinds of interfaces UART and gadgeteer which allow other microcontroller to talk to the player. You just put the audio files into SD card. Arduino or other microcontroller will play the audio files by sending the relevant name of audio files. The play is thus able to be controlled by PC. In addition,this module provides a port which will output high level after fishing a song.Now, it is the time to make your project talk with DFRduino Player module. Specification

Diagram
OUT:output 1ms Low level after finish a song
Attention
- The sd card must be formated at FAT format.
- YOU MUST Create a "sound" directory
- put mp3/wav/midi files under the SD card
- make sure the length of file name do not exceed 8 letters.
- The current should higher than 1000mA if use two speakers
- UART must be set 19200.
Support Commands
- Play music via receiving filename command "filename\r\n" Return "Play ok\r\n" if success. Return "Not found\r\n" if failed to find the file.
- Return "over\r\n" if finish playing one song.
- Pause Play "\:p\r\n" Return "pause\r\n" if success
- Continoue Play "\:s\r\n" Return "start\r\n" if success
- Play next "\:n\r\n" Return "next\r\n" if success，Return "false\r\n" if failed
- Play previous "\:u\r\n" Return "key up\r\n"
- Set the volume "\:v 255\r\n"，set the volume, from 0 (minimum)-255 (maximum), Return "vol set ok" if success
