LSM9DS1, noise coming on all channels when Accelerometer HPF is enabled

Nerd · ‎2018-07-26

I am using a LSM9DS1, the datasheet doesn't clearly state the settings for HPF cutoff for accelerometer.

Moreover, when I enabled HPF using Reg7_XL, I get 0.18g on all the axis, which is noise since my platform is stable. Can somebody help me with this?

@Nerd can you share you sensor configuration?

What do you write to CTRL_REG7_XL to enable HPF?

Nerd · ‎2018-09-23

DCF[1:0] set to 10

FDS set to 1

Rest of the bits are all 0

The high pass configuration is correct.

The noise cannot be 0.18g, I guess you misinterpret the output date or you have another mistake in your code.
