I'd be curious to see how well the MPU6000's internal "Digital Motion
Processing" handles in comparison to what Paparazzi already has for
AHRS. If it worked well it would be nice to offload the processing
from microprocessor to it. The MPU6000 even supports plugging a
magnetometer into it for more accurate measurements. Christophe, did
you play around with this DMP at all and make any findings?
