CONFIG_ADXL372_ACTIVITY_TIME

Activity time

Type: int

Help

The activity timer implements a robust activity detection that minimizes false positive motion triggers. When the timer is used, only sustained motion can trigger activity detection. Number of multiples of 3.3 ms activity timer for which above threshold acceleration is required to detect activity. It is 3.3 ms per code for 6400 Hz ODR, and it is 6.6 ms per code for 3200 Hz ODR and below.
