IIS2DLPC not responding via SPI, wrong component or issue with communication?.

Hi,We have received a new batch of boards and the sensor is not responding (The only change is the solder mask colour) to the "Who_am_I_ID" command. In the previous batch every thing worked as intended.Is it possible to, based on QR code, to see if t...

I have successfully built AlgoBuilder-based Firmware for my Target: NUCLEO-L476RG + X-NUCLEO-IKS02A1 + ISM330IS In Unicleo GUI, the data is streamed correctly for a few minutes but then stops abruptly. Why?

I put a logic analyzer on the I2C and INT1 line, and note that the INT1 continues to trigger but the I2C lines do not show data transfer anymore. Are there known issues? Is it a problem with the sensor or the host code? It may be dependent on the OD...

Possible bug in Unico GUI v9.13.0.0

Dear ST Community,Have no experience with STM32 MCUs nor with any programming IDEs used to develop for STM chips. As i am developing on espressif MCUs...However recently i am trying to integrate a MEMS sensor of STM into my project.I found out Unico ...

The 210/109 combination allows for a register set to select 1666 Hz. If I run the device and do a read only, it may almost run at 1666 Hz, but if you do any real reads and analysis wanting the acceleration, time and frequency the device runs slower

I have about 10 of these devices on about 6 computers, so this problem is common, the device runs at about 1200 to 1400 Hz. The picture shows a temperature, frequency and FFT results plot for one device. The typical is about 1400 +- 50. I take and...

LIS2MDL single shot issues

When running the single shot with offset cancellation mode we will occasionally get the following measurements for the magnetometer:x = -1y = 0 z = -1 temp = -1 This causes issues for us as we are manually averaging the two single shot values togethe...

Looking for alternative (drop in) product to BMG250 by Bosch Manufacturer

I am interested to use the device to determine the orientation of it in space using lis2dw12 only. As a test, I rotate the device 90 degrees each time over each one of the axes - Roll/Pitch and Yaw as presented in the attached figure.

I get the readings from ax,ay and az(plotted as well).Can the orientation of the lis2dw12 chip be derived from the DC levels? If so - how? What is the purpose of 6D orientation functionality and the accuracy of it?

FIFO timestamp (LSM6DSM)

Hi,i was trying to set up the pedometer and timestamp functionality for the FIFO.I was fallowing the instructions on page 102 (chapter 9.1) of the documentation for the setup (high timestamp resolution).It is working on a FIFO ODR of 104Hz. But if i ...
