Re: [Paparazzi-devel] Calibration Problem

[Prof. Dr.-Ing. Heinrich Warmers]

Hi Joey,
please follow the steps in this order:

1.  if you see  the name  of you aircraft on the ground station  the 
down connection is working
2. Change the messages to raw  data on the ground station (after that 
the PFD is not working)
3. if you get now answer the up link is not working
4.  if you see measure values the up and down link is working.
5. Use a oscilloscope and look for pulses on the CS wire of the MPU6000. 
If you see no pulses the initialization fails.

In most cases a problem wiht the aircaft xml file  is the problem.
Therfore try same of the examples you can find.
