How to read IMU information using STEVAL-MKI109D?

juseok · ‎2025-10-20

I connected STEVAL-MKI236A and STEVAL-MKI109D and confirmed that the IMU information comes from Mems studio and Unico.

My final goal is that this IMU value is output in serial communication.
I want to read the output IMU 6-axis information through python and match it to ros2 topic.

Please teach me the way.

Thank you. Have a nice day

The list of commands supported by the STEVAL-MKI109D is in the User Manual:

Or you would have to write your own firmware for the board.

The schematics are on the 'CAD Resources' of the Product Page:

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
