The integration of LIS2DW as a resonance measuring device in Klipper is becoming more and more common, especially because some manufacturers are promoting its superiority over the established ADXL345. It's indeed a new generation chip that should be better to measure traditional "accelerations". However, a detailed comparison of their datasheets and practical measurements paints a more complex picture: the LIS2DW boasts greater sensitivity, but it has a lower sampling rate and produce significant aliasing that results in a "lightshow" effect on the spectrogram, characterized by multiple spurious resonance lines parallel to the main resonance, accompanied by intersecting interference lines that distort the harmonic profile.
While, the top resonance graph's overall shape, including resonant frequency and damping ratio, should be close with pretty similar recommendations for input shaping filters, this aliasing complicates the identification of subtle details and hampers mechanical issue diagnostics. It especially introduces a potential misinterpretation of "[binding](#low-frequency-energy)" due to a global offset of the curve.
While in most cases the overall shape of the upper resonance curve, including resonant frequency and damping ratio, should be close to reality with fairly similar input shaping filter recommendations, this aliasing makes it difficult to identify subtle details and complicates the diagnosis of mechanical problems. In particular, it introduces a potential misinterpretation of "[binding](#low-frequency-energy)" due to a global offset of the curve. In the worst cases (see the last example below), the aliasing is too severe and adds too much noise to the graph, making it unusable.
