Hi, totally new to the Seeeduino XIAO board and was hoping to connect a DFPlayer Mini but using the code I normally use for Arduino I get this error - no matching function for call to ‘mp3_set_serial(Serial_&)’
This is required by the DFPLayer Mini Library to run and work correctly, I have tried Serial1 and that doesn’t work either.
Thanks in advance for any help
Please provide a link to the code.
Hi Baozhu, here is the example code from th DFPLayer Library which has the same line that won’t compile or upload.
#include <SoftwareSerial.h>
#include <DFPlayer_Mini_Mp3.h>
//
void setup () {
Serial.begin (9600);
mp3_set_serial (Serial); //set Serial for DFPlayer-mini mp3 module
mp3_set_volume (15);
}
//
void loop () {
mp3_play (1);
delay (6000);
mp3_next ();
delay (6000);
mp3_prev ();
delay (6000);
mp3_play (4);
delay (6000);
}
/*
mp3_play (); //start play
mp3_play (5); //play "mp3/0005.mp3"
mp3_next (); //play next
mp3_prev (); //play previous
mp3_set_volume (uint16_t volume); //0~30
mp3_set_EQ (); //0~5
mp3_pause ();
mp3_stop ();
void mp3_get_state (); //send get state command
void mp3_get_volume ();
void mp3_get_u_sum ();
void mp3_get_tf_sum ();
void mp3_get_flash_sum ();
void mp3_get_tf_current ();
void mp3_get_u_current ();
void mp3_get_flash_current ();
void mp3_single_loop (boolean state); //set single loop
void mp3_DAC (boolean state);
void mp3_random_play ();
*/
Many thanks

Many thanks, will download and give it a try.

Hi, could you allready check? It is working?
Hi, yes I got it working by using the “DFPlayerMini_Fast” library.
Great! Can you please share the settings / connections? I’m getting cracy. It works for me with the Wemos ESP32 mini, but not with the Xiao ESP32S3.
These are the settings I use
#include “SoftwareSerial.h”
#include “DFRobotDFPlayerMini.h”
SoftwareSerial mySoftwareSerial(7, 6); // RX, TX
DFRobotDFPlayerMini myDFPlayer;
void setup() {
mySoftwareSerial.begin(9600);
Serial.begin(115200);
if (!myDFPlayer.begin(mySoftwareSerial)) { //Use softwareSerial to communicate with mp3.
while(true){
}
}
myDFPlayer.volume(25); //Set volume value. From 0 to 30
myDFPlayer.play (3);
delay (1500);
myDFPlayer.play (2);
delay (300);
}
Connections image:
Hi, I found now the Error in my connection…
Your Settings couldn’t work for a XIAO ESP32S3 !?! SoftwareSerial.h?
For me this setting are now running with your connection:
#include “Arduino.h”
#include “DFRobotDFPlayerMini.h”
#define FPSerial Serial1
DFRobotDFPlayerMini myDFPlayer;
void setup()
{
FPSerial.begin(9600, SERIAL_8N1, /rx =/44, /tx =/43);
Serial.begin(115200);
Serial.println();
Serial.println(F(“DFRobot DFPlayer Mini Demo”));
Serial.println(F(“Initializing DFPlayer … (May take 3~5 seconds)”));
if (!myDFPlayer.begin(FPSerial, /*isACK = */true, /*doReset = */true)) { //Use serial to communicate with mp3.
Serial.println(F("Unable to begin:"));
Serial.println(F("1.Please recheck the connection!"));
Serial.println(F("2.Please insert the SD card!"));
while(true){
delay(0); // Code to compatible with ESP8266 watch dog.
}
}
Serial.println(F(“DFPlayer Mini online.”));

I know this is an old post now, but, just in case it helps or for anyone else looking at this; the DFPlayer has a built-in amp so the Pam8403 amp is unnecessary. Also, this set-up looks like it’s for a lightsaber usually those use high-powered LEDs if you are using those you will want to keep from running the power directly through your board so a MOSFET setup is recommended.
Hi Jc_Wentzel,
The code and diagram are for a Thermal Detonator not a Lightsaber. I know the DFPlayer Mini has a built in AMP, but many of the 3rd party Chinese copies give a better sound with the PAM8403 and it’s such a cheap board too. I know use only genuine DFPlayer Mini’s in my builds so no longer include the PAM8403. Many Thanks, regards Phil
