LIS2DW does not work properly

Hi,I am using nRF52805 with LIS2DW.LIS2DW is connected to nRF52805 with general GPIO, not I2C port.I am emulating GPIO to I2C protocol.SDA and SCL pin is pull-up to 100K resistors.After initializing LIS2DW, no need to use I2C bus.But, in this case, s...

designing schematics with LSM6DSO32XTR and LIS2DW12TR. Can you check and suggest if the schematics is okay, for us to go to production. We are using nrf5340 with these parts.

Hi, I'm using several VN5050AJ-E devices in our PCB. For contract ,I have to provide the global value MTBF/FIT of the PCB. I would need the MTBF/FIT of this component to calculate the value. Do you have MTBF/FIL value for VN5050AJ-E? Thanks

Is possible that the LIS2DW12 accelerometer reports via interrupt pin the Single and Double Tap condition at the same time?

Hi,I am developing an application using the accelerometer LIS2DW12. I need detect the single and double tap at the same time and indicate it to the microcontroller via interrupt pin what condition was detected.I have could detect single tap and doubl...

LIS331HH self-test output change with voltage

We have performed the self test on two prototype boards,as instructed in this post: https://community.st.com/s/question/0D50X00009XkXegSAF/lis331hh-understanding-self-testThe x and y differences are around 135, which is in the range, but on the z axi...

In MotionFX Library, which is the difference between Heading and Yaw?

The MotionFX library provide me quaternion and rotation angles (roll pitch and yaw). It is possible to obtain the accuracy for these data from the Library?

Hi, I'm using a board which embeds two ST MEMS: ism330dhcx and lis3mdl. I'm exploiting the MotionFX Library to obtain quaternion and rotation. Which is the way to obtain accuracy regarding roll pitch and yaw. I want to understand how close is the val...
