请尝试以下操作,看看你是否仍然得到相同的噪音输出:
确认x和y轴没有显示相同的噪声输出。
将灵敏度设置为2g。
设置高精度模式。
将采样率设置为10/50 / 100hz(我已经尝试过这些速率,它们对我来说效果很好)
关闭FIFO模式并尝试直接从28-2D寄存器中采样加速度值。
尝试将低位和高位读取为16位值。然后,您需要更改缩放系数以获得正确的g值。
我找到了这个线程,因为我在传感器上的z轴上看到的噪声比在x或y上看到的噪声更大。然而,与平均值的最大偏差仅为约0.05g(x和y倾向于保持在约0.025g内)。

Please try the following and see if you still get the same noisy output:
Verify that the x and the y axes do not show the same noisy output.
Set the sensitivity to 2g.
Set high precision mode on.
Set the sample rate to something like 10/50/100hz (I've tried these rates and they work well for me)
Turn off FIFO mode and try to sample the acceleration values directly from the 28-2D registers.
Try reading both the low and the high bits as a 16 bit value. You then need to change the scaling factors to get the correct g value.
I found this thread because I was seeing more noise in the z axis on my sensor than on the x or y. However, the maximum deviation from the mean is only about 0.05g (x and y tend to stay within about 0.025g).
