急求！关于ESP8266播放音乐的问题
#include <Arduino.h>#ifdef ESP32
#include <WiFi.h>
#include "SPIFFS.h"
#else
#include <ESP8266WiFi.h>
#endif
#include <AudioOutputNull.h>
#include <AudioOutputI2S.h>
#include <AudioGeneratorMIDI.h>
#include <AudioFileSourceSPIFFS.h>
AudioFileSourceSPIFFS *sf2;
AudioFileSourceSPIFFS *mid;
AudioOutputI2S *dac;
AudioGeneratorMIDI *midi;
void setup()
{
const char *soundfont = "/1mgm.sf2";
const char *midifile = "/furelise.mid";
WiFi.mode(WIFI_OFF);
Serial.begin(115200);
Serial.println("Starting up...\n");
audioLogger = &Serial;
sf2 = new AudioFileSourceSPIFFS(soundfont);
mid = new AudioFileSourceSPIFFS(midifile);
dac = new AudioOutputI2S();
midi = new AudioGeneratorMIDI();
midi->SetSoundfont(sf2);
midi->SetSampleRate(22050);
Serial.printf("BEGIN...\n");
midi->begin(mid, dac);
}
void loop()
{
if (midi->isRunning()) {
if (!midi->loop()) {
uint32_t e = millis();
midi->stop();
}
} else {
Serial.printf("MIDI done\n");
delay(1000);
}
}
我尝试用 ESP8266Audio 这个库做MP3播放的PlayMP3FromSPIFFS 这个例子，上传正常，连接电路也正常，可是开机为啥只有一直嘟的声音？
