DMP support for ICM-20948 IMU?

Development Boards Artemis

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.

Hi yootis,

There are some details on this here:

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
