Problem with MSGEQ7.

Hello

I picked up a couple of the MSGEQ7 IC's and connected as the attached image to Pro Mini.

Using the following code from the MSGEQ7 library (and I have tried others too), I get nothing but 7 lines of randomised high numbers. This is with no audio source attached.

Nice smooth 5.12v supply to the IC's. Nothing else sharing that supply. Common 0v to the Pro Mini.

Check the values of my components, and all seem correct. Didn't have a 200k, hence the dual 100Ks.

This happens on both IC's, so a dud chip is unlikely.

/*

#include <MD_MSGEQ7.h>

// hardware pin definitions - change to suit circuit
#define DATA_PIN    A0
#define RESET_PIN   11
#define STROBE_PIN  10

// frequency reading the IC data
#define READ_DELAY  50

MD_MSGEQ7 MSGEQ7(RESET_PIN, STROBE_PIN, DATA_PIN);

void setup() 
{
  MSGEQ7.begin();

  //pinMode(DATA_PIN,INPUT);
  //pinMode(RESET_PIN,OUTPUT);
  //pinMode(STROBE_PIN,OUTPUT);

  Serial.begin(57600);
  Serial.println("[MD_MSG_SEQ7_Serial]");
}

void loop() 
{
  // only read every READ_DELAY milliseconds
  static long prevTime = 0;
  
  if (millis() - prevTime >= READ_DELAY) 
  {
    prevTime = millis();

    MSGEQ7.read();

    // Serial output
    for (uint8_t i=0; i<MAX_BAND; i++)
    {
      Serial.print(MSGEQ7.get(i));
      Serial.print('\t');
    }
    Serial.println();
  }  
}

The output is:

Any ideas where I am going wrong?
