@phaedrux Right now I'm just using M956 to gather csv data. I can see the data as text and in the accelerometer plugin.
(edit) I found the plugin and while setting up the motion profile it stops during the "Please stand by while Motion Profiles are being recorded..." phase for the x axis, I need to cancel it (after waiting awhile) to get back to DWC.
(edit) switching to 8 bits creates data viewable in the gui, so I suppose I am ok now.
