Effect of STEP_COUNT_DELTA register on step count in STEP_COUNTER register

AB.4 · ‎2020-08-31

Hello ST community,

I was going through the application note for LIS2DS12 (https://www.st.com/resource/en/application_note/dm00218428-lis2ds12-alwayson-3d-accelerometer-stmicroelectronics.pdf) which mentions in section 5.9.1 that STEP_COUNT_DELTA can be configured to generate interrupt if a step is detected in a certain time period. Does configuration of this register also apply to the step count value in STEP_COUNTER register?

Regards,

Anusha

Hi Anusha @AB.4 ,

the step counter register only tracks the number of steps detected until it is reset (RST_nSTEP bit of reg STEP_COUNTER_MINTHS (3Ah) set to 1).

So: no, the STEP_COUNT_DELTA configuration does not affect the STEP_COUNTER register.
