Audio kit keeps rebooting

[deladriere]

I have the ESP32 Audio kit V2.2 and I am running this code:

#include <Arduino.h>

/**
 * @brief We use a predefied board (AudioKitEs8388V1) and output_device a sine
 * with the help of the AudioTools I2SCodecStream
 * @author phil schatzmann
 */

#include "AudioTools.h" // install https://github.com/pschatzmann/arduino-audio-tools
#include "AudioLibs/I2SCodecStream.h"

AudioInfo info(44100, 2, 16);
SineWaveGenerator<int16_t> sineWave(32000);
GeneratedSoundStream<int16_t> sound(sineWave);
I2SCodecStream out(AudioKitEs8388V1);
StreamCopy copier(out, sound);

void setup()
{
  // Setup logging
  Serial.begin(115200);
  AudioLogger::instance().begin(Serial, AudioLogger::Warning);
  LOGLEVEL_AUDIODRIVER = AudioDriverWarning;

  // start I2S & codec with i2c and i2s configured above
  Serial.println("starting I2S...");
  auto config = out.defaultConfig();
  config.copyFrom(info);
  out.begin(config);

  // Setup sine wave
  sineWave.begin(info, N_B4);
}

// Arduino loop - copy sound to out
void loop() { copier.copy(); }

on PlatformIO
with this platformio.ini

Compile and upload work fine, but it keeps rebooting with this message :

What am I doing wrong?
Thanks!

[pschatzmann]

AudioKitEs8388V1 must be wrong for your board and it does not have sda=33 scl=32 !
Did you try AudioKitEs8388V2 ?

[deladriere]

aha thanks !
it works, but the serial still reports warning :

[pschatzmann]

That's a feature of your board: The same pins are used for different things, which leads to conflicts...

class PinsAudioKitEs8388v2Class : public DriverPins {
 public:
  PinsAudioKitEs8388v2Class() {
    // sd pins
    addSPI(ESP32PinsSD);
    // add i2c codec pins: scl, sda, port, frequency
    addI2C(PinFunction::CODEC, 23, 18);
    // add i2s pins: mclk, bck, ws,data_out, data_in ,(port)
    addI2S(PinFunction::CODEC, 0, 5, 25, 26, 35);

    // add other pins
    addPin(PinFunction::KEY, 36, PinLogic::InputActiveLow, 1);
    addPin(PinFunction::KEY, 13, PinLogic::InputActiveLow, 2);
    addPin(PinFunction::KEY, 19, PinLogic::InputActiveLow, 3);
    addPin(PinFunction::KEY, 23, PinLogic::InputActiveLow, 4);
    addPin(PinFunction::KEY, 18, PinLogic::InputActiveLow, 5);
    addPin(PinFunction::KEY, 5, PinLogic::InputActiveLow, 6);
    addPin(PinFunction::AUXIN_DETECT, 12, PinLogic::InputActiveLow);
    addPin(PinFunction::HEADPHONE_DETECT, 39, PinLogic::InputActiveLow);
    addPin(PinFunction::PA, 21, PinLogic::Output);
    addPin(PinFunction::LED, 22, PinLogic::Output);
  }
};

[deladriere]

ah ok thanks !

[Frank-Bemelman]

Apologies for re-opening, but I have more or less the same problem, except the suggestions don't work. My board is ESP32 Audio Kit V2.2 A237

Same code as above, including same platformio.ini
My #include is slightly different:
#include "AudioTools/AudioLibs/I2SCodecStream.h"
... because there is where Platformio has installed this lib.

Compiles without problems. But my board keeps rebooting:

(and so on)

No idea how to attack this....
Any ideas?

Thanks in advance,
