ESP32 KorvoV1 microphone not working #55

Alright, meanwhile I am at the microphone part, the last part really.

I am not getting any input. I am using the "mic" example from the LyratMini examples. This is how I included it in Driver.h

 protected:
  AudioDriverES8311Class dac;
  AudioDriverES7210Class adc;

The pins are in DriverPins.h:

addI2S(PinFunction::CODEC_ADC, 0, 27, 26, -1, 36,0);

I tried leaving the port away and setting it to 0 and 1.

In es7210.h I set different I2C addresses, according to the schmematics. I tried with 40 and originally 80.

typedef enum {
    ES7210_AD1_AD0_00 = 0x80,
    ES7210_AD1_AD0_01 = 0x41,
    ES7210_AD1_AD0_10 = 0x42,
    ES7210_AD1_AD0_11 = 0x43

In the sketch I modified line 24 to:

AudioBoardStream i2s(KorvoV1); // Access I2S as stream

I also tried uncommenting lines 37, just to make sure.

Here is my log output. I see nothing specifically about the 7210.

Seems the 8311 goes into ENCODE mode, but isn't the 7210 the chip that would be used to encode for the microphones. Very litte about it in the logs,but I can see the sketch using the correct pins in the last lines of the log: 27,26,36.

What am I doing wrong?

TIA

Just check if the 7210 related code is called

I don't see any log outputs from the Driver.h class.
So I think it is not called. However, later on, in the log I see some I2S pin definitions, which are from DriverPins.h.

Code:

#include "AudioTools.h"
#include "AudioTools/AudioLibs/AudioBoardStream.h"

AudioInfo info(44100, 1, 16);
AudioBoardStream i2s(KorvoV1); // Access I2S as stream
CsvOutput<int16_t> csvStream(Serial);
StreamCopy copier(csvStream, i2s); // copy i2s to csvStream

// Arduino Setup
void setup(void) {
    Serial.begin(115200);
    // Display details what is going on
    AudioToolsLogger.begin(Serial, AudioToolsLogLevel::Debug);
    AudioDriverLogger.begin(Serial, AudioDriverLogLevel::Debug);
    
    auto cfg = i2s.defaultConfig(RX_MODE);
    cfg.copyFrom(info);
     cfg.i2s_function = PinFunction::CODEC_ADC;  // determined automatically
     // cfg.i2s_port_no = 1; // or 1 if 0 is already in use
    i2s.begin(cfg);

    // make sure that we have the correct number of channels set up
    csvStream.begin(info);

}

Driver.h:

class AudioDriverKorvoV1Class : public AudioDriver {
 public:
  bool begin(CodecConfig codecCfg, DriverPins &pins) {
    AD_LOGI("AudioDriverKorvoV1Class::begin");
    p_pins = &pins;
    codec_cfg = codecCfg;

    // setup SPI for SD
     pins.setSPIActiveForSD(codecCfg.sd_active);

    bool ok = true;

    // Start ES8311
    AD_LOGI("starting ES8311");
    dac.setPins(this->pins());
    ok = dac.setConfig(codecCfg);
    setPAPower(true);
    setVolume(DRIVER_DEFAULT_VOLUME); // originally DRIVER_DEFAULT_VOLUME

    // Start ES7210
    //if (codecCfg.input_device != ADC_INPUT_NONE) {
      AD_LOGI("starting ES7210");
      adc.setPins(this->pins());
      ok = ok && adc.setConfig(codecCfg);
    //}

    if (!ok) {
      AD_LOGI("AudioDriverKorvoV1Class::begin failed");
    }
    return ok;
  }
  bool end(void) {
    int rc = 0;
    rc += dac.end();
    rc += adc.end();
    return rc == 2;
  }
  bool setMute(bool enable) override { return dac.setMute(enable); }
  bool setVolume(int volume) override { return dac.setVolume(volume); }
  int getVolume() override { return dac.getVolume(); }
  bool setInputVolume(int volume) override { return adc.setVolume(volume); }
  int getInputVolume() { return adc.getVolume(); }
  bool isInputVolumeSupported() override { return true; }

};

mybe ok is false ? so adc.setConfig(codecCfg); might not be called...

I don't see how. Not any logs from this code. It looks like the whole code is not called.
