I have an OpenLog Artemis, and was wondering how to use the Digital Motion Processor (DMP) that is include in the 9-axis IMU. There are only a couple of references to how great it is in the datasheet, but nothing on how to use it.

Thank you very much to create this very good and useful lib! This helps a lot to test out the new imu sensor. Will there be a chance to get DMP supported in this library? As the sensor claims to have a better DMP performance and I really want to see how it goes. Thank you so much!

Hi @Windler,
Implementing the DMP functionality in the library and on OpenLog Artemis is still "under consideration". There is some discussion about it here:
https://github.com/sparkfun/OpenLog_Artemis/issues/47
Basically, we're not yet confident (enough) that we can implement it successfully... As far as we are aware, there's currently no clear recipe for enabling the DMP.
Very best wishes,
Paul
