AlashUartMP3

🌐 English | Русский

Arduino library for controlling UART-based MP3 player modules (e.g. boards built on the JQ8400 chip).

Installation

• Download: https://github.com/Alash-electronics/AlashUartMP3
• In the Arduino IDE: Sketch → Include Library → Add .ZIP Library…
• Select the downloaded AlashUartMP3.zip
• Examples are now available under File → Examples → AlashUartMP3 → HelloWorld

Usage

AlashUartMP3 works with any object that implements the Stream interface — a hardware Serial port, SoftwareSerial, or an ESP32's extra hardware UARTs.

Basic wiring

#include <AlashUartMP3.h>
AlashUartMP3 mp3(mySerial);

ESP32

#include <AlashUartMP3.h>
AlashUartMP3 mp3(Serial2);

Other initialization examples

#include <AlashUartMP3.h>
AlashUartMP3 mp3(mySerial); // SoftwareSerial

#include <AlashUartMP3.h>
AlashUartMP3 mp3(Serial);   // hardware Serial

#include <AlashUartMP3.h>
AlashUartMP3 mp3(Serial2);  // ESP32 second hardware UART

Examples

• HelloWorld / HelloWorld_ESP32 — minimal init and playback
• FullDemo — walkthrough of the full API
• PlayByNumber — play a specific track by index
• RandomPlay — shuffle playback
• SpecialAnnouncement — interrupt playback with a priority track
