Hello, I have problems connecting the Fermion I2S MEMS microphone to my Arduino Nano ESP32 board.

I have tried using different pins but nothing works. My multimeter shows the correct voltage only on the 3.3V pin.

Do you have any suggestions? Thanks

Here is the code:

#include “DFrobot_MSM261.h”

#define SAMPLE_RATE (44100)

#define I2S_SCK_IO (13)

#define I2S_WS_IO (12)

#define I2S_DI_IO (11)

#define DATA_BIT (16)

#define MODE_PIN (10)

DFRobot_Microphone microphone(I2S_SCK_IO, I2S_WS_IO, I2S_DI_IO);

char i2sReadrawBuff[100];

void setup() {

Serial.begin(115200);//Serial rate 115200

pinMode(MODE_PIN,OUTPUT);

digitalWrite(MODE_PIN,LOW);//Configure the microphone as receiving data of left channel

while(microphone.begin(SAMPLE_RATE, DATA_BIT) != 0){

Serial.println(" I2S init failed");//Init failed

}

Serial.println("I2S init success");//Init succeeded

}

void loop() {

microphone.read(i2sReadrawBuff,100);

//Output data of left channel

Serial.println((int16_t)(i2sReadrawBuff[0]|i2sReadrawBuff[1]<<8));

delay(100);

}
