#87345 I decoded the ESP8266 stacktrace I was getting in serial monitor:

Looks like its pointing to this library read_sensor_data.cpp

Code: Select all#include <Wire.h>
#include <Adafruit_ADS1015.h>
#include "read_sensor_data.h"

Adafruit_ADS1115 ads;

namespace SensorData
void read_sensor_data::initializeADC() {

int* read_sensor_data::analogValues()
      int* arr = new int[4];
      int16_t adc0, adc1, adc2, adc3;
      arr[0] = ads.readADC_SingleEnded(0);
      arr[1] = ads.readADC_SingleEnded(1);
      arr[2] = ads.readADC_SingleEnded(2);
      arr[3] = ads.readADC_SingleEnded(3);
      return arr;


but I do not understand what is wrong here. :roll:
