9 axis fusion

Hi

I'm using the MPU9250 and msp430 with the sdk application. I want to port the 9 axis fusion to a Cortex M0 and need to identify the code to get 9 axis quaternions.

In the fusion_9axis.h file, there is the function inv_enable_9x_sensor_fusion which is probably defined in the libmplmpu.lib file. But in the results_holder.c file, some functions get 6 axis quaternions to 9 axis quaternions.

Do I need both files to get the 9 axis quaternions like I will need to enable 9axis fusion than get quaternion with the results_holder.c file?

Thanks in advance
