1. Summary

1.1

.Brief Instruction

DFPLayer Mini module is a serial MP3 module provides the perfect integrated MP3, WMV hardware decoding.

While the software supports TF card driver, supports FAT16, FAT32 file system. Through simple serial

commands to specify music playing, as well as how to play music and other functions, without the cumbersome

underlying operating, easy to use, stable and reliable are the most important features of this module.

DFPLayer Mini 3. Serial Communication Protocol Serial port as a common communication in the industrial control field, we conducted an industrial level of optimization, adding frame checksum, retransmission, error handling, and other measures to significantly strengthen the stability and reliability of communication, and can expansion more powerful RS485 for networking functions on this basis, serial communication baud rate can set as your own, the default baud rate is 9600 3.1.

So that to ensure each communication get handshake signals, which will indicate the module has been successfully received data sent by the MCU and process immediately. 2).For general applications, customers can freely choose, without this response processing is also ok. 3.
