What does COUNTER_BDR_REG1?

Hi,I am using LSM6DSO and I am trying to implement the FIFO feature. I am reading from here (https://www.st.com/content/ccc/resource/technical/document/application_note/group0/56/95/d6/a1/34/4c/49/6d/DM00517282/files/DM00517282.pdf/jcr:content/transl...

X-Nucleo expansion board for LSM6DSO?

Hi, is ST planning to release new version of the X-NUCLEO-IKS01A2 sensor expansion board with the newest recently released sensors? I would like to interface LSM6DSO with NUCLEO-L4. Tks

LSM6DSO no interrupt

I have a LSM6DSO and I want to test it with the data ready interrupt, but I don't get any. I am using a logic analyzer to monitor the interrupt.The registers that I set are:0x18 with value 0x010x0B with value 0x010x10 with value 0x400x0D with value 0...

Resolved! H3LIS331DL: Threshold levels

I have the FS bits set for +/-100g scale.The accel data is a 12-bit signed value, meaning each bit represents 0.049g.The threshold registers however is only a 7-bit value. From what I understand, this is to be an unsigned magnitude level, representi...

IIS2DH sensing Die Location

Where in the 2x2 package is the sensing die for the 3 axis located? Is it dead center? A technical answer as accurate as possible would be best. And if there is some known manufacturing variance ​of this location. ​T​hanks

Interrupt generation for activity event

Hello,I have configured LIS2DH12 to generate interrupt on INT2 pin on activity as well as a strong impact using the register values as follows:CTRL_REG1 - 0x37CTRL_REG2 - 0x00CTRL_REG3 - 0x40CTRL_REG4 - 0x88CTRL_REG5 - 0x0ACTRL_REG6 - 0x28INT1_THS - ...

LSM9DS1 magnetic sensitivity

Posted on July 10, 2018 at 16:40The magnetic sensitivity for the LSM9DS1 is 0.14 mguass/LSB on its most sensitive range.  The LIS2MDL is 1.5 mguass/LSB.  Is the LSM9DS1 really 10X more sensitive?  If so, it would seem the best choice for application...
