BNO055 mounted vertically

[skinnychris]

Hi,

I've just started exploring using the BNO055, so please excuse my question if it's dumb. I chose the sensor because of the availiblity of Euler outputs, and that's what I'm using.

I have the sensor working correctly providing it's flat, but I wish to mount the sensor vertically. When I try using the sensor vertically, and try to remap the axis using the AXIS_MAP_CONFIG register I can't seem to get it to work. In my case, Y remains as the default reset value, but X and Z axis are swapped.

After the remap, Y doesn't seem to output anything sensible. With sensor vertical and stationary Y goes from 180 towards 0, or -180 towards 0, depending on the rotation around Y. The output of Y seems to start lagging the motion and not truly representative of the angle of its been rotated by.

Am I missing something here, like the remap doesn't work with Euler, or you can't mount the sensor vertically?

Cheers,

Chris

Hi,

Thank you for your inquiry. Please refer to the app note at https://www.bosch-sensortec.com/media/boschsensortec/downloads/application_notes_1/bst-mhs-an001.pdf for more informaiton regarding axes remapping.

Thanks.

Is it possible to draw a picture to show the target coordinate and chip location? Meanwhile, need to know the value you set(AXIS_MAP_CONFIG & AXIS_MAP_SIGN).
