using function: https://github.com/marcbishara/i2cdevlib/blob/master/Arduino/MPU6050/MPU6050_9Axis_MotionApps41.h#L753

Returns 0,0,0 Is that an outstanding issue or am I doing something wrong in setup?

I have the same problem!

I have the Arduino Nano, 2 MPU6050, 2 HMC5883L I want to get the output array with 20 values (the first board {3, 3, accelerometer, magnetometer 3, temperature}), the second board {3, 3, accelerometer, magnetometer 3, temperature}) Now I'm trying to make it work the first board (MPU6050+HMC5883L series connection). But i have the magnetometer (0.00,0.00,0.00); What do you think, what's the problem? my scheme

Have you tried adding pull-up resistors?

The AK8975's address is 0x0C,but the code give the address is 0x0E, so change the address to 0x0C.
