IIS328DQ PCB Design Guidelines Unclear

Not quite clear about the statement " "Pin 1 Indicator" unconnected during soldering " as mentioned in the datasheet. Can someone elaborate on this?In the Recommended Land and Soldermask design, the statement "PCB THERMAL PAD NOT TO BE DESIGNED ON P...

IIS3DWB INT1 / INT2 stopping/stuck at high after several Watermark events

Hi there,we are using two IIS3DWB (but the problem also occurs when only using one sensor) and trying to read out data from fifo when a certain watermark/threshold is reached.When polling the status register this works, but causes a lot of SPI traffi...

On a STM32F429I discovery, also when the board is not moving, the gyroscope furnish values different from zero and with high variance (on all the three axes). Is this noise or sensitivity? Is it possible to utilize some filter?

Is it possible to use an external clock source for lSM6DSL?

Hi, I am reading FIFO from a couple LSM6DSL IMUs, but the FIFO generation speed seems a bit different even if all of them are in the same configuration. I am suspect it is the different of the internal clock source. Does anyone know if it is possibl...

LPS Pressure-sensor: model differences and part naming scheme

I am looking for "cavity"-type pressure sensors like the LPS27 or LPS33 but I am having a hard time finding out what the differences between the models are. For the stm32f series the online documentation includes a great comparison chart of the diffe...

Sampling frequency of LSM6DSOX

Hello,I am measuring acceleration with LSM6DSOX.On account of unknown frequencies in measurement I want to know the relation between ODR and sampling rate.I found in https://www.st.com/resource/en/application_note/dm00571818-lsm6dsox-alwayson-3d-acce...

I've programmed the sensortile.box with the DataLogExtended example (from STBOX1). Everything seems to be working ok except for the fact that the Virtual COM port is not recognized (Windows 10)?

I would like to install the en.x-cube-mems1.zip V7.2.0 downloaded from st.com to STM32CubeMX Version 5.6.1.

However I faced the error message during installation​ that "Invalid zip file or missing expected Pdsc file within pack root directory".When unzip this file I can find the STMicroelectronics.X-CUBE-MEMS1.pdsc in the root dirctory "STM32CubeExpansion_...

What is the the size of SPAD array @VL53L3CX ?

In the docu's of VL53L3CX I couldn't find the size of SPAD array. For VL53L1X it was 16x16 pixels, but couldn't find actual data for VL53L3CX.
