Germar, Have a look at the post by Prof. Dr.-Ing. Heinrich
Warmers on 23 July 2010.
He has tested a low cost Sparkfun IMU ( RAZZOR IMU 6DOF Razor -
Ultra-Thin IMU) with the paparazzi hardware.

Contact hwarm or check out his branch in svn. I
believe they have this IMU working with the autopilot already.

Hi,
We are building a fixedwing Aircraft with tiny board.
We want to replace the Thermopiles with a AHRS System. We have purchased the
Sparkfun9DOF Razor IMU. On the IMU we are directly calculating eulerian angles
via the code provided by http://code.google.com/p/sf9domahrs/source/list.
We have activated the SPI interface on the board to communicate with the
paparazzi.
Has anybody done something similar or knows how to use the angles for roll and
pitch for stbilization? The code from the gyro.c only takes analogue
measurements, but since We have a digital interface we don't want to convert to
analogue just to convert back on the paparazzi.
cheers
Germar
