大家好,我想问一下LIS12DH阈值计算(附上我认为的计算),很明显,当我使用4g作为刻度时,我的计算结果是2.5g,当我移动传感器可以高于这个阈值并触发中断时,我只配置了Z轴,所以我只是在模拟一个下落运动, 但是当我用16g作为阈值时,我需要调整到6,按照同样的计算方法,6*16/255=0.376g,这个时候我以同样的方式移动,只是勉强触发运动,为什么?这与我设置的频率有关吗?因为在调整阈值的时候,我也调整了频率(100hz->4g,25hz->16g),非常感谢有人能替我回答!哦,我差点忘了。我已打开高通滤波器

Hi everyone, I want to ask about the LIS12DH threshold calculation (attached with what I think the calculation is), obviously when I use 4g as the scale, my calculation result is 2.5g, when I move the sensor can be above this threshold and trigger the interrupt, I only configured the Z axis, so I am just simulating a falling motion, but when I use 16g as the threshold, I need to adjust it to 6, according to the same calculation method, 6*16/255=0.376g, this time I move in the same way, just barely triggering the movement, why? Does this have something to do with the frequency I set? Because when adjusting the threshold, I also adjusted the frequency (100hz->4g, 25hz->16g), thank you very much if someone can answer it for me! Oh, I almost forgot. I have turned on the high pass filter
