Self test mode in LIS2DH12TR

Hello Team,

We want to test self-test mode in LIS2DH12TR.

We have followed below application note:

https://www.st.com/content/ccc/resource/technical/document/application_note/group0/55/ef/e4/9f/d1/e9/46/2c/DM00365457/files/DM00365457.pdf/jcr:content/translations/en.DM00365457.pdf

(Page - 57)

We have got below results and if we compare these results, it concluded as fail.

We are getting below average values before self-test enabled:

Avg: x: 1008 y: 932 z: 800

and after self-test enabled:

Avg X: 74 y: 1020 z: 743

So, If we found difference of above with respect to axes, only X axes followed the condition to pass the self-test, others were not.

Kindly help here.

Regards,

Parth Y Shah
