Folder and file names for DFPlayer_Mini
Account cancelled 2017-02-08 20:47:55 1517 Views1 Replies Hello,
I am using the MP3 player in the simplest way -- I/O mode as given here:

(I am controlling the ADKey and I/O pins using a microcontroller, but I don't have UART available, so cannot send commands.)
Should I place the .mp3 files in the root folder or in a folder named "mp3".
Thanks
AJ

Do you mean you want to play the mp3 via the ADkey and IO mode, right? If yes, there is no need to use UART. Only just connect vcc and gnd to a microcontroller and the horn. Insert the SD card to the module, then place the .mp3 files in the root folder named "mp3". Connect the diagram referring to the wiki, then you will can play the files using the switch. It is based on the principle of resistance voltage divider, not the UART.
Let me know if you have any problem. Wendy.Hu
