Goodmorning,
I've enabled the motion detection and now when my acceleration on the X-axis exceeds the threshold it works fine, but I want also that it continues to collect data while the device is moving at constant speed (acceleration = 0).
Does exist some embedded register to use the deceleration (breaking) as threshold for stop collecting data?
Thank you for you time.
Luigi
Hi Luigi,
The configurable threshold in the FF_MT_THS register is an absolute value and you can distinguish positive vs. negative using polarity flags (XHP, YHP and ZHP) in the FF_MT_SRC register.
I hope it helps.
Best regards,
Tomas
Hi Tomas,
Oh sure, you're right, I'd forgotten these register's proprieties.
But I have a question, the acceleration's polarity meanings are, for instance for the X axe:
if XHE = 1 we have an acceleration
if XHP = 1 we have a braking (deceleration)
And the polarity isn't correlated to the fact that I'm going forward or backward right?
Thank you in advance.
Luigi
