Hi @smichpresel ,
Version 1.7 of the firmware now lets you set the DLPF through the Configure IMU Logging menu. Can you please try updating to 1.7, set the Gyro DLPF to a low frequency, and post the results?
Many thanks,
Paul
Thanks Paul for the fast response!
Updating to v1.7 resolves the issue.
Already the no DLPF setting reduces the noise to expected levels and setting the DLPFs allow to go +-0.5dps (50Hz cuttoff).
Hi @smichpresel , Great! Glad that's fixed your issue. Thanks for letting me know. Best wishes, Paul
Hello to the sparkfun / OpenLog_Artemis team.
I enjoy using your nice device, however is seems that the 'no motion' gyro readings are very high. I am receiving readings in the range of +-10 degrees / second. Based on the gyro datasheet I would be expecting noise approximately one order of magnitude smaller.
By manually trying a constant turn rate - the scale of the measurement readings seems correct.
Setup
Artemis OpenLog v1.6 (but same observed on previous versions) Tested 4 different Artemis OpenLog boards Bare board connected to USB
Reproduce
Results can be directly seen using arduino Serial plotter
