What’s wrong with my code?

Hello everyone,
I was just wondering why this piece of code is not working.
The code get uploaded normally to arduino
But when I move the gyroscope it just give me random values of X & Y & Z
Im expecting 0,0, variable…
I checked the connection and it was correct
I thought either the sensor is broken or the code is wrong,
I’m using it to measure the acceleration of a moving object
Any ideas??
`

#include "MPU9250.h"

MPU9250 mpu;

void setup() {
    Serial.begin(115200);
    Wire.begin();
    delay(2000);

    if (!mpu.setup(0x68)) {
        while (1) {
            Serial.println("MPU connection failed. Please check your connection with connection_check example.");
            delay(5000);
        }
    }

   
    Serial.println("Accel Gyro calibration will start in 5sec.");
    Serial.println("Please leave the device still on the flat plane.");
    mpu.verbose(true);
    delay(5000);
    mpu.calibrateAccelGyro();

    Serial.println("Mag calibration will start in 5sec.");
    Serial.println("Please Wave device in a figure eight until done.");
    delay(5000);
    mpu.calibrateMag();

    print_calibration();
    mpu.verbose(false);
}

void loop() {
}

void print_calibration() {
    Serial.println("< calibration parameters >");
    Serial.println("accel bias [g]: ");
    Serial.print(mpu.getAccBiasX() * 1000.f / (float)MPU9250::CALIB_ACCEL_SENSITIVITY);
    Serial.print(", ");
    Serial.print(mpu.getAccBiasY() * 1000.f / (float)MPU9250::CALIB_ACCEL_SENSITIVITY);
    Serial.print(", ");
    Serial.print(mpu.getAccBiasZ() * 1000.f / (float)MPU9250::CALIB_ACCEL_SENSITIVITY);
    Serial.println();
    Serial.println("gyro bias [deg/s]: ");
    Serial.print(mpu.getGyroBiasX() / (float)MPU9250::CALIB_GYRO_SENSITIVITY);
    Serial.print(", ");
    Serial.print(mpu.getGyroBiasY() / (float)MPU9250::CALIB_GYRO_SENSITIVITY);
    Serial.print(", ");
    Serial.print(mpu.getGyroBiasZ() / (float)MPU9250::CALIB_GYRO_SENSITIVITY);

    I didn’t notice it.

  4. medic4950#0

    you call it on your setup function

  5. mr.aymen_ammari#0

    I will try this one as it is

  6. medic4950#0

    yep

  7. mr.aymen_ammari#0

    Could you tag me next time, I didn’t see the message 😅

  8. medic4950#0

    yes sure sorry

  9. mr.aymen_ammari#0

    Thank you so much @medic4950

  10. medic4950#0

    no problem
