When I read the quaternion values from addresses 109 and 110, the values the UM7 tives are nonsensical.
A always equals 1.0
B, C, and D always equal 0.0
How do I get the IMU to give the actual quaternion values?
Is quaternion mode enabled? Quaternion mode must be turned on for the attitude quaternion to be updated. You can do that from the Configuration tab in the Serial Interface.
I do not have the serial interface, but should I enable it through setting the quarternion mode bit on address 0x08?
Yeah, that should do it. Be aware that in quaternion mode, the magnetometer can influence all angles – yaw, pitch, and roll, not just yaw.
