I want to use yaw data, with hmc5883l for stable data. Anyone can help me?

Neither the MPU6050_6Axis_MotionApps20.h or MPU6050_9Axis_MotionApps41.h work with the hmc5883l. For get the values from the hmc5883l you need to use this function in the setup: void setI2CBypassEnabled(bool enabled); Line 1507 of this file: https://github.com/jrowberg/i2cdevlib/blob/master/Arduino/MPU6050/MPU6050.cpp

Enabling this function allows you to use the hmc5883l library for get the mag readings.

To fuse the mag values to the quaternion, i did'nt find any easy way. My final approache was to do the sensor fusion using Madgwick Algorithm.
