Problem managing libraries

Projects Libraries
1

Hi everyone,
I am trying to create a multiple sensor with audio and I am using a Teensy 4.1 with Audio shield, a ECG AD8232 and the accelerometer LIS3DH. I have a main code B3_V2.ino that posses numerous class (Sensors,LIS3DH, AudioShield etc.) When I try to compile, the accelerometer can not initialize. But when I test the example code provided by the library, it works fine. I do not understand why and I suppose it is due to library management but I have upload the library and the rest of the file are as presented below

and my code for the accelerometer :

#include "Arduino.h"
#include "LIS3DH.h"

// Used for software SPI
#define LIS3DH_CLK 27
#define LIS3DH_MISO 39
#define LIS3DH_MOSI 26
// Used for hardware & software SPI
#define LIS3DH_CS 37

// software SPI
Adafruit_LIS3DH lis = Adafruit_LIS3DH(LIS3DH_CS, LIS3DH_MOSI, LIS3DH_MISO, LIS3DH_CLK);

LIS3DH::LIS3DH()
{

  Serial.println("LIS3DH test!");
  if (!lis.begin(0x18))
  { // change this to 0x19 for alternative i2c address
    Serial.println("Couldnt start LIS3DH");
    while (1)
      yield();
  }
  // lis.setDataRate(LIS3DH_DATARATE_50_HZ);
  Serial.print("Data rate set to: ");
  switch (lis.getDataRate())
  {
  case LIS3DH_DATARATE_1_HZ:
    Serial.println("1 Hz");
    break;
  case LIS3DH_DATARATE_10_HZ:
    Serial.println("10 Hz");
    break;
  case LIS3DH_DATARATE_25_HZ:
    Serial.println("25 Hz");
    break;
  case LIS3DH_DATARATE_50_HZ:
    Serial.println("50 Hz");
    break;
  case LIS3DH_DATARATE_100_HZ:
    Serial.println("100 Hz");
    break;
  case LIS3DH_DATARATE_200_HZ:
    Serial.println("200 Hz");
    break;
  case LIS3DH_DATARATE_400_HZ:
    Serial.println("400 Hz");
    break;

  case LIS3DH_DATARATE_POWERDOWN:
    Serial.println("Powered Down");
    break;
  case LIS3DH_DATARATE_LOWPOWER_5KHZ:
    Serial.println("5 Khz Low Power");
    break;
  case LIS3DH_DATARATE_LOWPOWER_1K6HZ:
    Serial.println("16 Khz Low Power");
    break;
  }

  xvar = 0;
  yvar = 0;
  zvar = 0;
}

void LIS3DH::acquire()
{
  lis.read();

  // Serial.print("fin LIS3DH   : ");
  // Serial.println(micros());

  sensors_event_t event;
  lis.getEvent(&event);

  xvar = event.acceleration.x;
  yvar = event.acceleration.y;
  zvar = event.acceleration.z;
}

Does the compilation succeed ?

Yes it does when I compile everything is Ok but when I open the serial monitor it says

"Couldnt start LIS3DH"

However, when I replace the correct pin in the example acceldemo the accelerometer is detected and it works fine...
