YX5300 MP3 Music Player UART Control Serial Module In Pakistan

YX5300 UART Control Serial MP3 Music Player Module For Arduino/AVR/ARM/PIC. 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: Support sampling frequency (kHz): 8 / 11.025 / 12 / 16 / 22.05 / 24 / 32 / 44.1 / 48 Support file format: MP3 / WAV Support Micro SD card, Micro SDHC Card 30 class adjustable volume UART TTL serial control playback mode, baud rate is 9600bps Power supply can be 3.2 ~ 5.2VDC Instructions/ helpful Code: Save mp3 files in sd card and here is test code send + to arduino from serial terminal of arduino for next song and – for previous song. //www.hallroad.org // 11-25-16 test code for mp3 module #include SoftwareSerial mp3 ( 5 , 6 ) ;//5=rx , 6=tx static uint8_t cmdbuf[8] = {0}; char serial_byte=0; char song_no=1; void command(int8_t cmd, int16_t dat) { delay(20); cmdbuf [ 0 ] = 0x7e ; // byte start cmdbuf [ 1 ] = 0xFF ; // Version cmdbuf [ 2 ] = 0x06 ; // number of bytes command cmdbuf [ 3 ] = cmd ; // command cmdbuf[4] = 0x00; // 0x00 = no feedback, 0x01 = feedback cmdbuf [ 5 ] = ( int8_t ) ( dat >> 8 ) ; // PARAMETR DAT1 cmdbuf [ 6 ] = ( int8_t ) ( dat ) ; // PARAMETR DAT2 cmdbuf [ 7 ] = 0xef ; // Bajt konczacy for (uint8_t i = 0; i < 8; i++) { mp3.write(cmdbuf[i]); } } void setup() { Serial.begin(9600); mp3.begin(9600); delay ( 500 ) ; // We look forward to 500ms initialization command ( 0x09 , 0x0002 ) ; // Select SD card as a source delay ( 200 ) ; // Czekamu 200ms for initialization command ( 0x06 , 0x0064 ) ; // Set the volume to 30 command ( 0x03 , song_no ); } void loop() { if(serial_byte==’+’) {if(song_no<11) {serial_byte=0;song_no++;command ( 0x03 , song_no );}} else if (serial_byte==’-‘) {if(song_no>1) {serial_byte=0;song_no–;command ( 0x03 , song_no );}} } void serialEvent() { if (Serial.available()) { serial_byte = (char)Serial.read(); if (Serial.available()) char i= Serial.read(); } } Package includes: 1x  MP3 Music Player UART Control Serial  Module
