Solved
Blackpill and LIS3DH - issue with Sleep Mode.
When I use sleep mode while debug it sleep mode Works. But when I try runing code without using debug method it dosnot go in Sleep mode. When I chack current.
When using debug method stape by stape.
Without using stape by stape debug method.
Hear is the Code :-
