4, Circuit Board Size

5. Add Arduino library files and Mind+ library files

First find the Arduino library folder:

Copy the library file to the libraries folder in the Arduino IDE software directory and it's done:

Library file:Click to download

Add Mind+ library files

Library file:Click to download

After downloading, unzip the file to get the file...

Step 2: Open the mind+ extension library.

Step 3: Load the library and add the file just added

Now it can be used.

6. Download and store audio.

1. Connect the MP3 player module to the computer via the USB interface

2. Double-click to open My Computer

3. Copy the MP3 audio file and paste it into the MP3 playback module to move to disk G

Example program (UNO development board):

#include <GD5800_Serial.h>

GD5800_Serial mp356(5, 6);

void setup(){
  mp356.begin(9600);
  delay(1000);
  mp356.setLoopMode(MP3_LOOP_ALL);
  mp356.setVolume(255);
}

void loop(){
  //如上传程序mp3播报出现声音小或者只一曲循环；
  //请给单片机断电再重新给单片机上电。

  mp356.play();

}

8, ESP32 Python Example (for Mixly IDE / MiXChip)

Choose the development board Python ESP32 [ESP32 Generic(4MB)] and upload in code mode

Attention: If prompted with an error message about the library file during program upload, please import the library file first!

Example program (ESP32-Python):

import machine
import time


bofang = bytearray(b'\x7e\x02\x01\xef')
shunxuxh = bytearray(b'\x7e\x03\x07\x01\xef')
uart1=machine.UART(1, tx=21, rx=22, baudrate=9600)
uart1.write(bofang)
while True:
    uart1.write(bofang)
    time.sleep(1)
