Incorrect I2C device connected. Expected I2C addresses: [0x0C]. Detected I2C addresses: [0x69].

i am trying to connect a single mpu 9250 to arduino uno using matlab

as i run the command

imu=mpu9250(a) to create imu object it gave me an error

Incorrect I2C device connected. Expected I2C addresses: [0x0C]. Detected I2C addresses: [0x69].

why matlab is expecting device address as 0x0C is there any possible way to change it ?

Hey

Is the AD0 pin of the sensor connected to high?

Can you try creating the object by specifying the I2C addresses

imu = mpu9250(a,'I2CAddress',{'0x69','0x0C'})

MPU9250 has two I2C dies

1. Accelerometer-gyroscope (I2C Address can be 0x68 or 0x69,depending on the logical level on AD0 pin)
2. Magnetometer - This is AK8963 sensor (I2C Address - 0x0C)

Datasheet : MPU9250

Hope this helps

Thanks
