I'd like to measure some relativly low-frequency, low-intensity signals (rotations at less than 25 Hz), but there's a lot of strong vibrations (High frequency noise) in the environment my device is in. Is it possible to set a low pass filter in the ADXL-345?
If so, is it also possible to oversample? Say, measure at a frequency of 400 Hz, while the low pass filter cuts out noise above 25 Hz.
I didn't see anything in the datasheet about setting filters, so my guess is that I'm SOL. I suppose I could do all of this in software on a DSP, but I'm trying to target a low-power, low-feature microcontroller.
Thanks for your help!
