Is that right? > Thanks for reviewing, Jonathan, Correct. It says so in chapter 7.12. But that's a "problem" with all these imu devices, not specific to this addition right? Sidenote: I thought about renaming things to "lsm6ds0" here just because of the name and because the registers are (almost) the same as for my lsm9ds1. But I'm not a fan of blindly doing that without being able to test. When the current patchset looks good to you, let's keep it that way. martin
