Hm.. that is strange.
The mpu60x0_i2c peripheral works fine in the driver for the apogee autopilot.

What do you have set as gyro/accel sensitivity?
The drotek driver defaults to 1000 deg/s and 4g as mentioned before... the defaults should be correct in the latest of imu_drotek branch.
We still need a better way to set the defaults according to the configured range. Also not sure what the best default range is...

Cheers, Felix

Hi Felix
I did some tests today and it looks like the new mpu60x0 subsystem does not work as intended.
The artificial horizon does not move at all and the raw accelerator ang gyro values look strange, here are some sample values:
From the Accelerometer (raw values)
ax = -65636
ay = 3018600
az = 720872

And from the gyro (raw again)
gp = -1572818
gq = 10
gr = 0

The magnetometer values are always 0.

I also get some warnings during compile time about mismatched pointer types.
