It would be of interest and importance for the Kalman filter to estimate the sensor variance and mean value.

  • Implement CLI command to start a sensor sampling task
  • After taking some samples (not too many, we have limited memory space) calculate variance/standard dev/mean etc. with DSP
  • Print values to USB

Perhaps we should use dynamic memory allocation for this so we can unallocate/free used memory after we have taken sensor samples for this

Note to self: use arm_var_f32 and arm_mean_f32 declared in arm_math.h file.
