Is there any problems with the MPU6050 sensor library?

I am currently doing a project with MPU6050 sensor, and i found the example code for MPU9150 from TivaWare.

I tried to run the code for MPU9150 to MPU6050, and it works (but iam not sure if the data is correctly)

But i tried to change the code to MPU6050 and run again. Then errors occurs

I found that my program stops here

//
// Initialize I2C3 peripheral.
//

I2CMInit(&g_sI2CInst, I2C3_BASE, INT_I2C3, 0xff, 0xff,
ROM_SysCtlClockGet());

//
// Initialize the MPU6050 Driver, preparing it for operation.
//
MPU6050Init(&g_sMPU6050Inst, &g_sI2CInst, MPU6050_I2C_ADDRESS,
MPU6050AppCallback, &g_sMPU6050Inst);

//
// Wait for transaction to complete
//
// program stops here
MPU6050AppI2CWait(__FILE__, __LINE__);

Hi,

This is the continuation from your post below.

Question about MPU9150 sample code from TI

The MPU9150 library works as I have tested it with the Sensor Hub. As mentioned at the post above, there is some bugs with it.

How are you connecting MPU6050 sensor to your Tiva kit? Also, what is the Tiva kit that you are using.

The program will stop there if certain flags are not set.

I use TM4C123GH6PM ( EK - TM4C123GXL)

i connect:

SCL to PD0

SDA to PD1

AD0 t0 Ground

INT to PB2

Which are the same as the sample code for MPU9150

But i already ran the sample code from MPU9150, and it works although for MPU6050 sensor.

Same circuitry with MPU9150 at SensorHub? Verify I2C signals using oscilloscope, if you have one.

i searched on the forum, i and saw that somebody said that they found some errors with the mpu6050 library.

i think that there may be problems with the configuration for mpu6050 leading to errors!
