Re: [Paparazzi-devel] My IMU for paparazzi is almost done. Few test flights are successfully performed

Hi Andrew


  What is the update rate of your IMU? we are work on the IMU using  
the same sensor, ecept we added the magneto sesnor for heading. The  
communication is also done though SPI.
  We have not yet done any flight test yet, but should be quite soon  
with out 40cm wing span aircraft (I hope ).


  It will be nice to see what your IMU hardware and flight test.


Regards

                                                                       Chen
