LIS3DH bad?

wally3D

I have a LIS3DH connected to a duet2 wifi, RRF 3.4.1. It seems to be correctly connected, M955 P0 provides:

Accelerometer 0 type LIS3DH with orientation 46 samples at 1344Hz with 10-bit resolution, SPI frequency 2000000

At 10 bits, a blank csv file is written when running M956.

Sample,X,Y,Z
Failed to collect data from accelerometer

Running M956 when set to 8 bits writes a csv as it should, but the data in all 3 axes is flat. I am using the M956 code from the wiki.

Can the LIS3DH be wired incorrectly to the board and still be recognized correctly? Or, could the board be defective?

Are you trying to use the Input shaping plugin?

@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.
