Hello
I'm using the MPU 9250 and I'm trying the Saving and Loading Calibration Data by using Motion Driver 6.12.
In App Note 1 - Motion Driver 6.12 Getting Started, there are functions about caliblation
inv_error_t inv_save_mpl_states(unsigned char *data, size_t sz)
inv_error_t inv_load_mpl_states(const unsigned char *data, size_t length)
Would you tell me how to make "unsigned char *data".
