ISM330xxx version with higher precision

On a workshop I heard of this. For an application I would need a bit more precision especially in gyro resolution / stability. Can you please send me information on this and the MEMS identifier, eg ISM330HLC or ISM330DHC ... Are samples available, e....

LIS2DW12 fails to issue fifo interrupt sometimes

I'm setting up LIS2DW12 to 100Hz, low power mode 1, fifo threshold 30 and fifo interrupt on INT2.When interrupt is received by MCU (STM32L4 here) i readout register 0x2F to know how much samples is to retrieve, then retrieve them all by issuing read ...

Problems using the VL53L0X in a 3D printed tube

I would like to use the VL53L0X in a 3D printed tube with limited space. The diameter is 6,5mm.Since the emitter and collector have a conical characteristic, there are limitations as describes in an earlier post: https://community.st.com/s/question/0...

SPI Stopped Working

Hi,I'm working with a STM32F401 Nucleo-64 board. The board is connected to a mems accelerometer (IIS2DH) via SPI, and I'm using the HAL library.Everything was working good and I was able to retrieve samples from the accelerometer. Suddenly one day la...

LIS2DH12TR

I'm new to Accelerometer Sensor.I have few questions o this LIS2DH12TR.There are two Interrupt pins on this LIS2DH12TR.The interrupt pins are meant for Threshold detection and sending the LIS2DH12TR to sleep/wakeup mode? Can you briefly explain the f...

Recovery of Standby Mode in LIS3DH + STM32L072

Recovery of Standby Mode in LIS3DH + STM32L072I am developing using LIS3DH + STM32L072 now.I think that I want to restore with WKUP (PA0) of STM32L072 by INT1 when it enters Standby Mode and exceeds the threshold set to LIS3DH.However, I will not ret...
