HI all,

I added a define IMU_DROTEK_2_ORIENTATION_IC_UP, which will negate the y and z-axes so you can mount it with the ICs facing up.
You can configure the gyro, accel range, lowpass, etc... And if you check the "print config at build time" box in paparazzi center it will show what you configured.
If you change the range, you however will have to set the appropriate sensitivity in your airframe file.

Committed this to master now...

Cheers, Felix

Hi Felix i think it is working fine now :-)
Here are some RAW sample values and since the "x" axis only remain the same
and all other are reversed in my setup, the recorded values look correct.
Also note that i removed all my definitions about the sensitivity and let the default values
defined in the driver files.
I think that it should be noted that if you follow this orientation the imu must be positioned
with the ICs facing down including the barometer.

Would be great if you could test again and check the scale as well as the
axes assignment.
