Re: [Paparazzi-devel] a direction question about lisa/m 2.0 board

[Hao Zhang]

Hi Balazs!
thanks for your reply.
you are right, on the Aspirin IMU wrote axis as below:

         x
         |
         |
y-------N

so the x point is the front, right?

and my another question whitch is the upside in the calibrating the
accelerometers.
is the lisa/m board upside or the Aspirin IMU board upside?(you know
that they are opposite)
